Comparison of cyclacillin and amoxicillin for therapy for acute maxillary sinusitis. (1/8)

Cyclacillin, a new aminosalicylic semisynthetic penicillin, was compared with amoxicillin for the therapy of acute bacterial maxillary sinusitis in 80 patients (ages, 12 to 70 years) in a prospective, double-blind, randomized clinical trial. Direct sinus aspirations for quantitative culture were done for all patients before and after 10 days of therapy. Both drugs were administered at a dosage of 500 mg orally three times daily. Among culture-positive patients, clinical cure was achieved in 23 of 26 patients and 25 of 27 patients treated with cyclacillin and amoxicillin, respectively, for an overall cure rate of 91%. Bacteriologic failure occurred in 9% (4 of 44 patients); 3 of the 4 failures were in the cyclacillin group. There was no correlation between clinical or bacteriologic cure and the results of sinus transillumination (clear, dark) at follow-up. Initial direct sinus aspirates were positive in 57 of 80 cases (70%): 25 (44%) of these were the result of Streptococcus pneumoniae and 23 (40%) were the result of Haemophilus influenzae. All of these isolates were susceptible (MIC, less than or equal to 0.5 microgram/ml) to both study drugs; no ampicillin-resistant H. influenzae was recovered. On day 10 of therapy, mean concentrations of both drugs in serum were 2.5 to 2.7 micrograms/ml, but no antibiotic was detectable in 20 of 21 simultaneous sinus aspirates. Adverse effects (rash, diarrhea) were infrequent and similar in both groups. Cyclacillin appears equivalent to amoxicillin in the therapy of acute maxillary sinusitis.  (+info)

Double-blind clinical trials of oral cyclacillin and ampicillin. (2/8)

A double-blind study was performed to compare the clinical response and the incidence of side effects in 2,581 patients administered ampicillin or cyclacillin for infections of the genitourinary or respiratory tract, infections of the skin and soft tissues, or for otitis media. There was no significant difference in clinical response and bacterial eradication. All side effects, including diarrhea and skin rash, were approximately twice as frequent in patients treated with ampicillin.  (+info)

Susceptibility of anaerobic bacteria to beta-lactam antibiotics and beta-lactamase production. (3/8)

We examined the susceptibility of various anaerobes to four beta-lactamase susceptible (ampicillin, amoxycillin, cyclacillin, and penicillin G) and two beta-lactamase resistant (moxalactam, and N-F-thienamycin) beta-lactam antibiotics and measured beta-lactamase production. Members of the Bacteroides groups were most resistant to the six antibiotics. N-F-thienamycin was the most effective antimicrobial agent against all the test strains, moxalactam the next most effective, and penicillin G the least. Beta-lactamase production was mainly confined to Bacteroides species. Cephalosporinase was the most common beta-lactamase produced; penicillinase was detected less often. About two thirds of the penicillin-resistant isolates produced cephalosporinase. N-F-thienamycin and moxalactam were the most active agents against those anaerobes that were resistant to many beta-lactam antibiotics.  (+info)

Pharmacological and in vitro evaluation of cyclacillin: assessment as potential single-dose therapy for treatment of Neisseria gonorrhoeae infection. (4/8)

The pharmacokinetic properties of cyclacillin administered as a 3.0-g oral dose, with and without progenecid, have been studied and correlated with in vitro activity of the drug against 109 isolates of Neisseria gonorrhoeae. By 8 h after dosage, levels of cyclacillin in serum declined below the minimal inhibitory concentration and the inferior antibacterial activity of cyclacillin (compared with that of amipicillin) suggest that cyclacillin is not a promising alternative to ampicillin for single-dose treatment of gonorrhea.  (+info)

Comparative pharmacokinetics of cyclacillin and amoxicillin in infants and children. (5/8)

Concentrations of cyclacillin in serum over a 6-h period were similar in fasted and milk-fed infants who received 25-mg/kg doses of cyclacillin suspension. Measured by the concentration in serum after oral administration of 15-mg/kg doses, cyclacillin was absorbed more rapidly, reached larger concentrations, and was cleared more promptly than was amoxicillin.  (+info)

Differential recognition of beta -lactam antibiotics by intestinal and renal peptide transporters, PEPT 1 and PEPT 2. (6/8)

This study was initiated to determine if there are differences in the recognition of beta -lactam antibiotics as substrates between intestinal and renal peptide transporters, PEPT 1 and PEPT 2. Reverse transcription-coupled polymerase chain reaction and/or Northern blot analysis have established that the human intestinal cell line Caco-2 expresses PEPT 1 but not PEPT 2, whereas the rat proximal tubule cell line SKPT expresses PEPT 2 but not PEPT 1. Detailed kinetic analysis has provided unequivocal evidence for participation of PEPT 2 in SKPT cells in the transport of the dipeptide glycylsarcosine and the aminocephalosporin cephalexin. The substrate recognition pattern of PEPT 1 and PEPT 2 was studied with cefadroxil (a cephalosporin) and cyclacillin (a penicillin) as model substrates for the peptide transporters constitutively expressed in Caco-2 cells (PEPT 1) and SKPT cells (PEPT 2). Cyclacillin was 9-fold more potent than cefadroxil in competing with glycylsacosine for uptake via PEPT 1. In contrast, cefadroxil was 13-fold more potent than cyclacillin in competing with the dipeptide for uptake via PEPT 2. The substrate recognition pattern of PEPT 1 and PEPT 2 was also investigated using cloned human peptide transporters functionally expressed in HeLa cells. Expression of PEPT 1 or PEPT 2 in HeLa cells was found to induce H(+)-coupled cephalexin uptake in these cells. As was the case with Caco-2 cells and SKPT cells, the uptake of glycylsarcosine induced in HeLa cells by PEPT 1 cDNA and PEPT 2 cDNA was inhibitable by cyclacillin and cefadroxil. Again, the PEPT 1 cDNA-induced dipeptide uptake was inhibited more potently by cyclacillin than by cefadroxil, and the PEPT 2 cDNA-induced dipeptide uptake was inhibited more potently by cefadroxil than by cyclacillin. It is concluded that there are marked differences between the intestinal and renal peptide transporters in the recognition of beta -lactam antibiotics as substrates.  (+info)

Absorption of amino penicillins from everted rat intestine. (7/8)

1. Using an in vitro everted gut sac method based on that of Wilson & Wiseman (1954), a number of amino penicillins were tested in order to identify the involvement of any specialized transport mechanisms in their absorption across rat intestine. 2. Only one of the amino penicillins, cyclacillin (1-amino-cyclohexyl penicillin) was shown to be actively transported. The other penicillins appeared to diffuse passively across the intestine. 3. Cyclacillin was found to concentrate against a gradient at 37 degrees C but not at 19 degrees C. 4. Transport of cyclacillin across the mucosal membrane was saturated at mucosal concentrations greater than 1000 microgram/ml. 5. The rate of the forward flux of cyclacillin was many times that of its back flux. 6. No relationship between the active transport of cyclacillin and that of amino acids could be demonstrated.  (+info)

Recognition of beta-lactam antibiotics by rat peptide transporters, PEPT1 and PEPT2, in LLC-PK1 cells. (8/8)

PEPT1 and PEPT2 are H(+)-coupled peptide transporters expressed preferentially in the intestine and kidney, respectively, which mediate uphill transport of oligopeptides and peptide-like drugs such as beta-lactam antibiotics. In the present study, we have compared the recognition of beta-lactam antibiotics by LLC-PK1 cells stably transfected with PEPT1 or PEPT2 cDNA. Cyclacillin (aminopenicillin) and ceftibuten (anionic cephalosporin without an alpha-amino group) showed potent inhibitory effects on the glycylsarcosine uptake in the PEPT1-expressing cells. Other beta-lactams, such as cephalexin, cefadroxil, and cephradine (aminocephalosporins), inhibited modestly the PEPT1-mediated glycylsarcosine uptake. Except for ceftibuten, these beta-lactams showed much more potent inhibitions on the glycylsarcosine uptake via PEPT2 than via PEPT1. Comparison of the inhibition constant (Ki) values between cefadroxil and cephalexin suggested that the hydroxyl group at the NH2-terminal phenyl ring increased affinity for both PEPT1 and PEPT2. It is concluded that PEPT2 has a much higher affinity for beta-lactam antibiotics having an alpha-amino group than PEPT1 and that substituents at the NH2-terminal side chain of these drugs are involved in the recognition by both peptide transporters.  (+info)

Author(s): Wang, Genzhu; Li, Liang; Wang, Xiukun; Li, Xue; Zhang, Youwen; Yu, Jie; Jiang, Jiandong; You, Xuefu; Xiong, Yan Q | Abstract: Bacteremia is a life-threating syndrome often caused by methicillin-resistant Staphylococcus aureus (MRSA). Thus, there is an urgent need to develop novel approaches to successfully treat this infection. Staphylococcal accessory regulator A (SarA), a global virulence regulator, plays a critical role in pathogenesis and β-lactam antibiotic resistance in Staphylococcus aureus. Hypericin is believed to act as an antibiotic, antidepressant, antiviral and non-specific kinase inhibitor. In the current study, we investigated the impact of hypericin on β-lactam antibiotics susceptibility and mechanism(s) of its activity. We demonstrated that hypericin significantly decreased the minimum inhibitory concentrations of β-lactam antibiotics (e.g., oxacillin, cefazolin and nafcillin), biofilm formation and fibronectin binding in MRSA strain JE2. In addition, hypericin

Growth of E. coli at pH 5 protected the bacteria against the lytic effect of beta lactam antibiotics typically observed when the cells are grown at pH 7 or 7.5, i.e., the pH values routinely used in laboratory experiments. In contrast, the typical effects of beta lactam antibiotics on cellular shape and elongation and cell division appeared to be similar in cultures grown under neutral and acid pH conditions. The pH-dependent antibiotic tolerance can also be demonstrated with pneumococci, staphylococci, streptococci, and Bacillus subtilis. We suggest that the mechanism of the pH-dependent antibiotic tolerance may involve either the production of a more stable plasma membrane or the suppression of the activity of a murein hydrolase(s) that catalyzes the antibiotic-induced lysis; at least a fraction of these enzyme molecules may be localized at the cell surface and be accessible to experimental manipulation.. ...

AU - Sinko, Patrick J.. PY - 1988/10. Y1 - 1988/10. N2 - The oral absorption of five cephalosporin antibiotics, cefaclor, cefadroxil, cefatrizine, cephalexin, and cephradine, has been studied using a single-pass intestinal perfusion technique in rats. Intrinsic membrane absorption parameters, unbiased by the presence of an aqueous permeability (diffusion or stagnant layer), have been calculated utilizing a boundary layer mathematical model. The resultant intrinsic membrane absorption parameters are consistent with a significant carrier-mediated, Michaelis-Menten-type kinetic mechanism and a small passive component in the jejunum. Cefaclor colon permeability is low and does not exhibit concentration dependent behavior. The measured carrier parameters (±SD) for the jejunal perfusions are as follows: ...
An increase in the copper pool in body fluids has been related to a number of pathological conditions, including infections. Copper ions may affect antibiotics via the formation of coordination bonds and/or redox reactions. Herein, we analyzed the interactions of Cu2+ with eight β-lactam antibiotics using UV-Vis spectrophotometry, EPR spectroscopy, and electrochemical methods. Penicillin G did not show any detectable interactions with Cu2+. Ampicillin, amoxicillin and cephalexin formed stable colored complexes with octahedral coordination environment of Cu2+ with tetragonal distortion, and primary amine group as the site of coordinate bond formation. These β-lactams increased the solubility of Cu2+ in the phosphate buffer. Ceftazidime and Cu2+ formed a complex with a similar geometry and gave rise to an organic radical. Ceftriaxone-Cu2+ complex appears to exhibit different geometry. All complexes showed 1:1 stoichiometry. Cefaclor reduced Cu2+ to Cu1+ that further reacted with molecula...r ...
Darcie Long, a fourth-year in the Chemistry-Biology Interface Program and one of the authors of this study, explained that while most of the clinically relevant β-lactam antibiotics have two fused structures, a different class, called moncyclic antibiotics, only has one ring structure.. Although most antibiotics are bicyclic, Long says the monocyclic antibiotics are of increasing interest because of their relative resistance to metalloproteases and β-lactamases, which are enzymes involved in conferring antibiotic resistance to some pathogenic bacteria.. Therefore, to better understand this single-ring class of antibiotics, the authors investigated the ring formation in one specific family: norcardicin.. Long and lead author Nicole Gaudelli worked together on all of the benchwork that led to the discovery of the mechanism. They found how the nonribosomal peptide synthetases (NRPSs) were able to create a ring structure in the norcardicin family. Intriguingly, this enzyme has been identified in ...
The results of the current study are encouraging, with the minority of studied patients exhibiting adverse symptoms, most of which were triggered during the hospital rather than the home provocation. Data from the current study do not exclude the possibility that reactions may occur hours to days after a single-day provocation attempt. The authors pose the question of whether all patients who will react are able to be provoked with a single-day attempt with prolonged subsequent observation. Additional study is needed to assess larger numbers of children with nonimmediate adverse reactions to β-lactam antibiotics. Additional data on risk assessment and pretest predictive measures will lead to benefits both for individual patients and community antibiotic stewardship. ...

The studies described here were designed to probe the similarities and contrasts that exist between the mecA homologues carried by two staphylococcal species, S. aureus and S. sciuri. In S. aureus, the mecA gene is acquired from an unknown extraspecies source: it is present only in methicillin-resistant strains, providing these bacteria with blanket resistance against the most important class of antimicrobial agents-the family of β-lactam antibiotics. In S. sciuri, a close structural homologue of the S. aureus mecA gene appears to be a domestic gene present in each one of the large number of independent isolates examined. Yet, in contrast to the case ofS. aureus, S. sciuri strains carrying themecA gene homologue are uniformly susceptible to all β-lactam antibiotics (4). S. sciuri is a staphylococcal species taxonomically remote from S. aureus,and it is unlikely that these bacteria have often been exposed to β-lactam antibiotics in their natural habitat, which is the skin of rodents and ...
Penicillins and cephalospororins are the most prescribed group of antibiotics. They belong to half-synthetic beta lactam antibiotics. These antibiotics work by inhibiting the enzymes responsible for the production of peptidoglycan. Peptidoglycan is a biopolimer that is a main structural component of the bacterial cell wall. The blockage of peptidoglycan synthesis leads to the lysis of the microorganisms. Another group of preparations are aminoglycosides. However, these antibiotics are prescribed in rare cases. The most of aminoglycosides possesses nephrotoxicity, ototoxicity and cab cause neuromuscular blockage. Bactericidal action of aminoglycosides is related to the interfering with the synthesis of proteins on the ribisomes in the microbial cells. When aminoglycosides are used with penicillins and cephalosporins the sinergism against gram-positive and gram-negative microorganisms is observed. Among all bacteriostatic antibiotics macrolides and tetracyclines are the most indicated groups. ...

Growing incidence of β-lactam resistance mediated by Extended Spectrum β-Lactamases (ESBLs) and Metallo-β-lactamases (MBLs) is a major concern due to their extreme resistance towards the commonly used antibiotics. The present study was undertaken to determine the in-vitro effect of antibiotic encapsulated micro/multiple emulsions on clinical isolates of 68 ESBL and 7 MBL-producing uropathogens by agar diffusion method. The water in oil (w/o) microemulsions of amoxicillin (particle size 11-15nm) and ceftazidime (particle size 17-19nm) did not exhibit antibacterial activity. However, water in oil in water (w/o/w) multiple-emulsion of both the drugs exhibited activity. Further, the effect of glyceryl dilaurate (GDL), a lipid emulgent having inherent antibacterial activity was studied. Ceftazidime multiple emulsions, with and without GDL showed zones of inhibition against all test uropathogens in the range of 11-32mm. Amoxicillin w/o/w multiple-emulsion without GDL was found to be ineffective. However,
Rate coefficients for the inactivation of several penicillin in acids and alkalis at 30°C have been determined by means of ultraviolet spectroscopy. The case of benzylpenicillin, though well investigated in the past, has been studied again and, in the light of new experiments, a scheme detailing the proportions of the various degradation products has been proposed. A number of substituted phenylpenicillins have been synthesised, and their reactions with acid have been investigated. Product analysis was carried out by means of TLG and NMR studies, the degradation products (penicilloic, penilloic, penillic and penicillenic acids) having been previously prepared and characterised. From the manner in which the phenyl substituent on the penicillin affects the rate coefficient, it is deduced that the mechanism of inactivation by acids involves a rate-determining intramolecular attack by the side-chain carbonyl group on the protonated β-lactam function. An intermediate oxazolone-thiazolidine ...

The rate of aminolysis of benzylpenicillin and cephaloridine by hydroxylamine, unlike other amines, shows only a first order dependence on amine concentration. The rate enhancement compared with that predicted from a Bronsted plot for other primary amines with benzylpenicillin is greater than 106. This is much more than an -effect and is compatible with rate-limiting formation of the tetrahedral intermediate due to a rapid intramolecular general acid catalysed breakdown of the intermediate. For cephaloridine, the rate enhancement is greater than 104 which demonstrates that -lactam C-N bond fission and expulsion of the leaving group at C3 are not concerted.. ...
Due to widespread resistance to penicillin, the current treatment of choice for S. aureus infections is semi-synthetic penicillin molecules. This resistance is due to the activity of the enzyme penicillinase, which cleaves the β-lactam ring of the penicillin molecule. Penicillinase-resistant β-lactam antibiotics include methicillin, oxacillin, and flucoxacillin. S. aureus strains that have acquired resistance to methicillin have an altered penicillin-binding protein (PBP2a) that has lower affinity for binding β-lactam antibiotics, thus rendering them ineffective. Strains that have acquired this resistance are referred to as methicillin-resistant S. aureus (MRSA). The current gold standard for treatment of MRSA is vancomycin. However, vancomycin is far from ideal due to poor tissue penetration, slow bactericidal activity, and a number of side effects (Gould, 2008). Additional antibiotics utilized include teicoplanin, tegecyline, linezolid, daptomycin, and televancin. Each of those medications ...
Inhibitory effect of commercial antibiotics and bioactive compounds produced by the isolate W3 against vibrios. Most of the antibiotics used could cause inhibition of all tested strains of V. harveyi (Table 1), Hence antibiotics could be used to control V. harveyi infections that affect aquaculture in Thailand. However, some of them such as chloramphenicol, furazolidone, tetracycline and oxonilic acid are now banned for use in aquaculture as previously mentioned. In general, β-lactam antibiotics such as ampicillin are preferred for use by shrimp farmers to treat luminous vibriosis disease since these groups of antibiotics do not cause significant side effects (Teo et al. 2002). Unfortunately, all tested strains in this study were resistant to ampicillin and this result is in agreement with Teo et al. (2002) who reported that many types of β-lactam antibiotics were no longer able to prevent vibriosis. In Thailand sulphamethoxazole is normally used in hatcheries against Vibrio sp.; however, in ...
Pneumococcal disease was studied prospectively to determine the risk factors associated with resistance to penicillin and other antibiotics. One hundred twelve clinically significant pneumococcal isolates were recovered from 95 patients. Approximately one-half (49.47%) of the cases were due to penicillin-resistant strains. Multivariate analysis showed that previous use of β-lactam antibiotics (odds ratio [OR], 2.81; 95% confidence interval [CI], 0.95-8.27), alcoholism (OR, 5.22; 95% CI, 1.43-19.01), and noninvasive disease (OR, 4.53; 95% CI, 1.54-13.34) were associated with penicillin resistance, whereas intravenous drug use (OR, 0.14; 95% CI, 0.03-0.74) was not. Statistical analyses of the variables associated with resistance to multiple antibiotics detected age of younger than 5 years (OR, 16.79; 95% CI, 1.60-176.34) or of 65 years or older (OR, 4.33; 95% CI, 1.42-13.21) and previous use of β-lactam antibiotics by patients with noninvasive disease (OR, 7.92; 95% CI, 1.84-34.06) as parameters ...
Detectable compounds comprising a chemically-transformable first compound covalently linked to an electrochemiluminescent compound are provided. Such compounds are useful in processes and kits that monitor the status of the first compound and derive information from such monitoring. A rapid single step assay suitable for the detection or quantification of β-lactam antibiotics and β-lactamases. The assay can be performed directly on samples of food, such as milk and meat, blood or serum and is useful in determining the suitability of a particular antibiotic in treating a particular bacterial infection and in diagnosis of a bacterial infection. The assay is also useful in determining and quantifying β-lactam antibiotic resistance. The assay can be performed on an IGEN OrigenR Analyzer.
This study was designed to detect and compare ESBLs distribution among vaginal E. coli isolates from pregnant and non-pregnant women. Most of this study-included isolates were resistant to CTX and more than half of them were resistant to CAZ. All of CAZ resistant isolates were also resistant to CTX. The members of Enterobacteriaceae possess many mechanisms of resistance to β-lactam antibiotics, however, β-lactamases are the most common and clinically significant mechanism of resistance to β-lactam antibiotics among this bacterial group [7]. Four types of ESBLs were detected in this study, namely: TEM-, SHV-, CTX-M-, and OXA-type. Of this study-included isolates, 65.5% (40/61) were ESBL producers by PCR technique. In Iraq, previous researchers [17, 18] reported ESBL production by 100% of enteropathogenic E. coli (EPEC) isolates from infants, most of them were suffering from watery diarrhea for more than 10 days, for that they were hospitalized. The important reason for this difference with ...
The neurotoxic potential of intravenous administered benzylpenicillin (BPC) was studied in rabbits with intact blood-CNS barriers and rabbits with experimental E. coli meningitis. At onset of epileptogenic EEG activity or seizures, serum, CSF and brain tissue were collected for assay of BPC. Based on the fact that, in tissues, BPC seems to remain extracellularly, brain concentrations of BPC were expressed as brain tissue fluid (BTF) levels, calculated as lOx the concentration in whole brain tissue. Neurotoxicity could be precipitated in all rabbits. In normal rabbits BTF levels of BPC were considerably higher than those in CSF indicating a better penetration across the blood-brain barrier (BBB). BPC penetrated better to CSF and BTF in meningitic rabbits than in normal controls, suggesting some degree of damage of the BBB concomitant with meningeal inflammation. E. coli meningitis did not increase the neurotoxicity of BPC. In control rabbits the intracistemal injection of saline resulted in some ...
Background -lactam level of resistance in Gram-negative bacteria is a substantial clinical issue in the grouped community, long-term care services, and hospitals. fast and accurate approach to visualizing the SHV category of enzymes in medical examples including Gram-negative bacilli utilizing a fluorescein-labeled polyclonal antibody. Background Level of resistance to -lactam antibiotics in Gram-negative bacterias can be a Volasertib substantial medical issue in the grouped community, long-term treatment, and hospital configurations [1-3]. In the normal Gram-negative bacterias that are in charge of most medical infections, -lactam level of resistance results from creation of penicillinases (mainly the -lactamases specified TEM-1 and SHV-1), cephalosporinases (e.g., extended-spectrum -lactamases, ESBL, of TEM-, SHV- and CTX-M-types), as well as the plasmid or chromosomally encoded AmpC enzymes [1]. Hence, an intense search for book therapeutic real estate agents and fast, accurate detection ...
Side effects are similar to those for other β-lactam antibiotics, including nausea, vomiting, rashes, and antibiotic-associated colitis. Loose bowel movements (diarrhea) may also occur. Rarer adverse effects include mental changes, lightheadedness, insomnia, confusion, anxiety, sensitivity to lights and sounds, and unclear thinking. Immediate medical care is required upon the first signs of these adverse effects.[citation needed] The onset of an allergic reaction to amoxicillin can be very sudden and intense; emergency medical attention must be sought as quickly as possible. The initial phase of such a reaction often starts with a change in mental state, skin rash with intense itching (often beginning in fingertips and around groin area and rapidly spreading), and sensations of fever, nausea, and vomiting. Any other symptoms that seem even remotely suspicious must be taken very seriously. However, more mild allergy symptoms, such as a rash, can occur at any time during treatment, even up to a ...
β-lactamases (EC 3.5.2.6) [1,2] are enzymes which catalyze the hydrolysis of an amide bond in the β-lactam ring of antibiotics belonging to the penicillin/cephalosporin family. Four kinds of β-lactamase have been identified [2]. Class-B enzymes are zinc containing proteins whilst class -A, C and D enzymes are serine hydrolases. Class-B β-lactamases have been described in several Gram-negative bacterial species; they seem to share the characteristic of being able to hydrolyze carbapenem compounds which are new β-lactam antibiotics of great therapeutic potential. There are a number of conserved regions in the sequence of known class-B β-lactamases [3]. Most of them are centered on residues known [4] to be involved in binding the zinc ion essential for the enzymes catalytic activity. We designed two signature patterns for this class of enzyme. The first contains three residues involved in binding zinc ions. The second pattern contains a cysteine which is also a zinc ligand. Last update: ...
Open in another window Infections due to hard-to-treat methicillin-resistant (MRSA) certainly are a serious global public-health concern, while MRSA is becoming broadly resistant to numerous classes of antibiotics. of attacks in intensive treatment devices in 1974 to 64% in 2004,3 although newer data statement stabilization of the instances.4,5 Over time, -lactams had been antibiotics of preference for treatment of infections. Nevertheless, these agents confronted obsolescence using the introduction of MRSA in the first 1960s.6 Presently, the only effective agents for treatment of MRSA infections are vancomycin, daptomycin, and linezolid,7 although only linezolid could be dosed orally.8 Level of resistance to all or any three has surfaced.9?13 Thus, fresh anti-MRSA therapeutic strategies are needed, especially providers that are orally bioavailable.14 Clinical resistance to -lactam antibiotics by Compound 56 MRSA offers its basis in the acquisition of the gene,15 which encodes penicillin-binding ...
β-lactam antibiotics are widely used for the treatment of different types of infections worldwide and the resistance to these antibiotics has grown sharply, which is of great concern. Resistance to β-lactams in gram-negative bacteria is mainly due to the production of β-lactamases, which are classified according to their functional activities. The aim of this study was to verify the presence of β-lactamases encoding genes in feces, soil, and water from a Brazilian pig farm. Different β-lactamases encoding genes were found, including blaCTX-M-Gp1, blaCTX-M-Gp9, blaSHV, blaOXA-1-like, blaGES, and blaVEB ...
Antibiotic resistance to clinically employed β-lactam antibiotics currently poses a very serious threat to the clinical community. The origin of this resistance is the expression of several β-lactamas
Two classification plans for β-lactamases are in make use of. subgroups of each of the major groups are explained based on specific attributes of individual enzymes. A list of attributes is also suggested for the description of MK-5108 a new β-lactamase including the requisite microbiological properties substrate and inhibitor profiles and molecular sequence data that provide an adequate characterization for a new β-lactam-hydrolyzing enzyme. MK-5108 Hydrolysis of β-lactam antibiotics by β-lactamases is the most common mechanism of resistance for this class of antibacterial brokers in clinically important Gram-negative bacteria. Because penicillins cephalosporins and carbapenems are included in the favored treatment regimens for many infectious diseases the presence and characteristics of these enzymes play a critical role in the selection of appropriate therapy. β-Lactamase production is most frequently suspected in a Gram-negative bacterial isolate that demonstrates resistance to a ...
The emergence of carbapenemase producing bacteria, especially New Delhi metallo-β-lactamase (NDM-1) and its variants, worldwide, has raised amajor public health concern. NDM-1 hydrolyzes a wide range of β-lactam antibiotics, including carbapenems, which are the last resort of antibiotics for the treatment of infections caused by resistant strain of bacteria. In this review, we have discussed bla NDM-1variants, its genetic analysis including type of specific mutation, origin of country and spread among several type of bacterial species. Wide members of enterobacteriaceae, most commonly Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, and gram-negative non-fermenters Pseudomonas spp. and Acinetobacter baumannii were found to carry these markers. Moreover, at least seventeen variants of bla NDM-type gene differing into one or two residues of amino acids at distinct positions have been reported so far among different species of bacteria
Abstract. Metallo-β-lactamases (MBLs) cause resistance of Gram-negative bacteria to β-lactam antibiotics and are of serious concern, because they can inactivate the last-resort carbapenems and because MBL inhibitors of clinical value are still lacking. We previously identified the original binding mode of 4-amino-2,4-dihydro-5-(2-methylphenyl)-3H-1,2,4-triazole-3-thione (compound IIIA) within the dizinc active site of the L1 MBL. Herein we present the crystallographic structure of a complex of L1 with the corresponding non-amino compound IIIB (1,2-dihydro-5-(2-methylphenyl)-3H-1,2,4-triazole-3-thione). Unexpectedly, the binding mode of IIIB was similar but reverse to that of IIIA. The 3 D structures suggested that the triazole-thione scaffold was suitable to bind to the catalytic site of dizinc metalloenzymes. On the basis of these results, we synthesized 54 analogues of IIIA or IIIB. Nineteen showed IC50 values in the micromolar range toward at least one of five representative MBLs (i.e., L1, ...

Artemisinin (ART) and its derivatives artesunate (AS), dihydroartemisinin (DHA) are a group of drugs containing a sesquiterpene lactone used to treat malaria. Previously, AS was shown to not have antibacterial activity but to significantly increase the antibacterial activities of β-lactam antibiotics against E. coli. Herein, molecular docking experiments showed that ART, AS and DHA could dock into AcrB very well, especially DHA and AS; both DHA and AS had the same docking pose. The affinity between AS and AcrB seemed weaker than that of DHA, while the succinate tail of AS, which was like a

At constant pH and temperature, the degradation followed pseudo-first-order kinetics at the initial concentration of 5 mM. The shape of the rate-constant-pH profile of cefaclor resembled those for cefatrizine and other aminocephalosporins. At neutral pH, cefaclor was degraded via intramolecular nucleophilic attack of the α-amino group on the β-lactam moiety. The intramolecular reaction rate was very similar to that in the cases of ...
Summary: The effect of different β-lactam antibiotics on the growth and morphology of Myxococcus xanthus has been examined. Exposure to penicillin and cephalexin resulted in spheroplast and filament formation, respectively. Mecillinam appeared to inhibit cell elongation and caused the formation of bent cells with central bulges. Myxospore formation was inhibited by cephalexin but not by mecillinam, although myxospores formed in the presence of mecillinam showed defects after germination. Germination of myxospores involves substantial cell-wall turnover as measured by uptake and loss of meso-diamino[14C]pimelic acid. Although turnover was observed when myxospores were germinated in the presence of mecillinam, the bacteria remained as spheres. Growth of these germinated myxospores following removal of mecillinam indicated that wall material laid down during the early stages of germination is stable and a rod shape could be re-established only by bipolar growth of new wall.

Enterobacteriaceae is a family of Gram negative bacilli which can cause a wide range of community acquired and nosocomial infections including infections of the urinary and gastrointestinal tracts, pneumonia, peritonitis, meningitis, sepsis and medical device associated infections (Surinder Kumar, 2012; Wang et al., 2015; Harbaik et al., 2014). These organisms easily acquire and transfer drug resistance genes through plasmids and transposons (Okoche et al., 2015). Carbapenem are beta lactam antibiotics and are the last resort for the treatment of severe infections caused by multidrug resistant Gram negative bacilli (Gupta et al., 2006; Roy et al., 2011). Reports indicate that carbapenemases producing Enterobacteriaceae (CRE) isolates seem to be increasing in number in the last few years (Nagaraj et al., 2012).
Sri Lanka-based company Navesta Pharmaceuticals has opened a sterile manufacturing facility in the town of Horana in August 2017.. Construction began in October 2015, and the plant is said to be the first of its kind in Sri Lanka. The facility is intended to produce sterile dry powder injectables of beta lactam antibiotics, which were previously imported to the country.. Built with an investment of more than LKR1.4bn ($9.1m), the Horana facility has generated more than 100 direct and 500 indirect jobs for locals in areas including bio-chemistry, pharmaceutical sciences, molecular bio-science, drugs, engineering, and ancillary services.. The factory will allow Navesta to export its pharmaceutical products to markets globally, contributing to the countrys economic development. It will also support the Government of Sri Lankas aim to achieve self-sufficiency in the pharmaceutical industry by 2020.. ...

A racemic synthesis of two diastereoisomeric α-benzyloxycarbonylamino substituted trans-fused bicyclic lactams (4 and 5), was achieved from cyclopentene oxide. These lactams are useful intermediates to investigate the possibility of using a trans-lactam template as a replacement for the β-lactam ring found i
A beta-lactam (β-lactam) ring is a four-membered lactam. (A lactam is a cyclic amide.) It is named as such because the nitrogen atom is attached to the β-carbon atom relative to the carbonyl. The simplest β-lactam possible is 2-azetidinone. The β-lactam ring is part of the core structure of several antibiotic families, the principal ones being the penicillins, cephalosporins, carbapenems, and monobactams, which are, therefore, also called β-lactam antibiotics. Nearly all of these antibiotics work by inhibiting bacterial cell wall biosynthesis. This has a lethal effect on bacteria, although any given bacteria population will typically contain a subgroup that is resistant to β-lactam antibiotics. Bacterial resistance occurs as a result of the expression of one of many genes for the production of β-lactamases, a class of enzymes that break open the β-lactam ring. More than 1,800 different β-lactamase enzymes have been documented in various species of bacteria. These enzymes vary widely in ...
High affinity for PBP 2′ is crucial for the antibacterial activity of β-lactams against MRS. Unfortunately, none of the available β-lactam antibiotics sufficiently fulfils this requirement. This fact increasingly limits the therapeutic potential against staphylococcal infections of these otherwise very useful drugs.. However, the intensive search for new antistaphylococcal drugs has shown recently (1, 7, 11, 12, 14) that it is possible to achieve strong inhibition of PBP 2′ with selected β-lactam structures. Ro 63-9141 is a member of the class of pyrrolidinone-3-ylidenemethyl cephems, which show high potency against PBP 2′ of S. aureus but higher IC50s against normal, sensitive PBPs than other β-lactam antibiotics, e.g., methicillin and imipenem. This appears to be a common property of the pyrrolidinone-3-ylidenemethyl cephems, as it has been observed before for other members of this structural class (7). Ro 63-9141 shares features of cephalosporins with 7-aminothiazolylhydroxyimino ...

Antibiotic potential for people who are injured get infection are high. First aid to evade the infection use antibiotics. Antibiotics have ability to inhibit or kill bacteria that cause infection. Tetracycline is antibiotic that usually uses for first treatment because of tetracycline easy to obtain. There are six classification of carbapenem antibiotic such as imipenem, ertapenem, mesopenem, and doripenem. Doripenem is one of the classification of carbapenem that can be obtained easily. Doripenem can be used for first aid if infection is happened. Silver usually uses too for avoiding infection but it is not easily to degrade. It is necessary to find antibacterial composites that easily to find and biodegradable. The purpose of this research is to study the effect of pH, kinetic, and isotherm adsorption of doripenem into bentonite. The optimum condition of doripenem adsorption will be determined. After knowing the optimum condition, the antibacterial composite will be tested on nutrient agar. ...
Background & Aims: The production of extended-spectrum-β-lactamases (ESBLs) is the main mechanism of resistance to β-lactam antibiotics. The outbreak of isolates simultaneously possessing several resistance mechanisms to β-lactam antibiotics caused a decrease in sensitivity of the confirmatory tests for ESBL. The aim of this study was the evaluation of the β-lactamase disk test method in the detection of ESBLs in clinical isolates of multidrug-resistant Pseudomonas aeruginosa. Methods: A total of 100 multidrug-resistant P. aeruginosa isolates were recovered from burn patients. The sensitivity of the isolates to different antibiotics was determined using the standard disk diffusion method. ESBL-producing isolates were detected through the combination disk test with clavulanic acid, double disk synergy test, and β-lactamase disk test. Carbapenemase-producing isolates were detected using the Modified Hodge Test (MHT). The ESBLs genes (blaTEM, blaOXA, blaPER, blaSHV, blaCTX-M and blaPSE) were
Abstract: The diazabicyclooctanes (DBOs) are a class of serine β-lactamase (SBL) inhibitors that use a strained urea moiety as the warhead to react with the active serine residue in the active site of SBLs. The first in-class drug, avibactam, as well as several other recently approved DBOs (e.g., relebactam) or those in clinical development (e.g., nacubactam and zidebactam) potentiate activity of β-lactam antibiotics, to various extents, against carbapenem-resistant Enterobacterales (CRE) carrying class A, C, and D SBLs; however, none of these are able to rescue the activity of β-lactam antibiotics against carbapenem-resistant Acinetobacter baumannii (CRAB), a WHO critical priority pathogen producing class D OXA-type SBLs. Herein, we describe the chemical optimization and resulting structure-activity relationship, leading to the discovery of a novel DBO, ANT3310, which uniquely has a fluorine atom replacing the carboxamide and stands apart from the current DBOs in restoring carbapenem ...
Members of the proton-coupled oligopeptide transporter (POT) family are responsible for transporting small peptides across the cell membrane. The mammalian PepT1 and PepT2 transporters play a key role in this process for dietary peptide uptake in the small intestine and peptide retention in kidney, respectively, and are capable of recognizing and transporting a diverse library (~8000 combinations) of di- and tri-peptides. Recently, PepT1 has also been shown to transport drugs with peptide-like structures, such as β-lactam antibiotics. This makes PepT1 and PepT2 attractive targets to improve drug uptake and bioavailability within the body.. My work focuses on the functional dynamics of PepTso, a bacterial homologue of PepT1. Given the high substrate promiscuity of these peptide transporters, the binding site must be incredibly accommodating and flexible in order to recognize and transport various substrates. Using solid-state NMR, electron spin resonance, and other biophysical techniques, I will ...

The Klebsiella pneumoniae carbapenemase (KPC) was detected in a carbapenem-resistant respiratory isolate of Klebsiella pneumoniae in an Irish hospital. This is the first report of a KPC-producing isolate in the Republic of Ireland. The isolate was resistant to all β-lactams. Furthermore, it had reduced susceptibility to three other classes of non-β-lactam antibiotics. The isolate was not associated with travel abroad. Detection of KPC-producing bacteria has important infection control and public health implications.

Cysteinyl variants on the α3 and L3 regions, which flank the di-ZnII active site, were selectively 19F-labeled using 3-bromo-1,1,1-trifluoroacetone. The PrOF NMR results reveal roles for the mobile α3 and L3 regions in the binding of both inhibitors and hydrolyzed β-lactam products to SPM-1. These results ...
In this study, we report the development of an SPR (Surface Plasmon Resonance) immunosensor for the detection of ampicillin, operating under flow conditions. SPR sensors based on both direct (with the immobilization of the antibody) and competitive (with the immobilization of the antigen) methods did not allow the detection of ampicillin. Therefore, a sandwich-based sensor was developed which showed a good linear response towards ampicillin between 10−3 and 10−1 M, a measurement time of ≤20 min and a high selectivity both towards β-lactam antibiotics and antibiotics of different classes.
The art of war is simple enough. Find out where your enemy is. Get at him as soon as you can. Strike him as hard as you can, and keep moving on.. -Ulysses S. Grant. Since the discovery of antibiotics, there has been a conflict between antibiotics and bacterial mutations and resistance. This has led to an arms race of sorts in which bacteria have undergone modifications that facilitate the development of resistance to progressive generations of antibiotics. Staphylococcus aureus, a bacterium frequently found in the nose and skin of patients, is now noted to be one of the most common causes of hospital-based infections and contamination of postsurgical wounds. Bacteria such as S aureus rapidly developed resistance to the penicillins, which led to the development of the so-called β-lactamase-resistant penicillins such as methicillin. However, with the emergence of methicillin-resistant S aureus (MRSA), bacteria have now developed resistance to all β-lactam antibiotics.. The review article by Mah ...
TY - JOUR. T1 - Extended-spectrum β-lactamases. AU - Patterson, Jan E.. PY - 2000/1/1. Y1 - 2000/1/1. N2 - Resistance to broad-spectrum cephalosporins among Klebsiella pneumoniae has increased significantly, particularly in the intensive care unit setting, in the past decade. The problem has been noted not only in the United States, but around the world. A major mechanism responsible for this is the emergence of extended-spectrum β-lactamases (ESBLs). These plasmid-mediated β-lactamases confer resistance to broad-spectrum β-lactam antibiotics, including third and fourth-generation cephalosporins, aztreonam, and extended-spectrum penicillins. Other resistances, such as aminoglycoside and trimethoprim-sulfamethoxazole resistance, are often cotransferred on the same plasmid. Fluoroquinolone resistance is also frequently associated, resulting in an organism resistant to most broad-spectrum options. The carbapenems are currently considered the drug of choice for these pathogens. Prevention and ...
A membrane-bound, bacterial enzyme inhibited by penicillin and other β-lactam antibiotics, which acylate the active site serine. Examples are known from peptidase famili
Among relevant metal ions in biological systems, zinc and iron play a key role as active partners of the catalytic machinery. In particular, the inhibition of metal enzymes that are involved in physiological and pathological processes has been deeply investigated for the rational design of selective and efficient drugs based on chelators. Since imidazole histidine residue is one of the most versatile sites in proteins, especially in enzymes acting in the presence of metal ions as cofactors, in this work the synthesis and characterization of a new imidazole derivative, namely 5-methyl-2-phenoxymethyl-3-H-imidazole-4-carboxylic acid (PIMA) is reported. PIMA was designed as metallo-β-lactamase inhibitor thanks to its similarity with penicillin V, a β-lactam antibiotic inactivated by metallo-β-lactamase, for which there are no commercially available inhibitors. The evaluation of PIMA coordinating ability toward iron, zinc, and gallium, these latter selected as a non-paramagnetic probe for ...
Third-generation cephalosporins are a class of β-lactam antibiotics that are often used for the treatment of human infections caused by Gram-negative bacteria, especially Escherichia coli. Worryingly, the incidence of human infections caused by third-generation cephalosporin-resistant E. coli is increasing worldwide. Recent studies have suggested that these E. coli strains, and ... read more their antibiotic resistance genes, can spread from food-producing animals, via the food-chain, to humans. However, these studies used traditional typing methods, which may not have provided sufficient resolution to reliably assess the relatedness of these strains. We therefore used whole-genome sequencing (WGS) to study the relatedness of cephalosporin-resistant E. coli from humans, chicken meat, poultry and pigs. One strain collection included pairs of human and poultry-associated strains that had previously been considered to be identical based on Multi-Locus Sequence Typing, plasmid typing and antibiotic ...
The metallo-β-lactamases (MBLs) are enzymes with the ability to hydrolyse the β-lactam antibiotics. The worldwide emergence of the antibiotic resistant MBLs poses an increasing clinical threat. The VIM enzymes are a growing family of carbapenemases with a wide geographic distribution in Europe, South America and the USA. The VIM-7, the first VIM enzyme to be discovered in the USA, is the most divergent member of the VIM-enzymes with the closest similarity to VIM-1 with a 77% amino acid identity. The VIM-7 has a conserved D120 in the active site, which, in catalysis, plays an important role. The Y224 residue present in the VIM-2, which currently is the most widespread MBL, is though to have an impact on the activity. Three site-directed mutations of the VIM-7, with a previously solved structure, were made; D120A, D120N and H224Y respectively. All three mutants and the VIM-7 wt were sequenced, and the mutants VIM-7 D120A and VIM-7 H224Y with the VIM-7 wt, containing an N-terminal hexahis-tag and ...
Metallo-β-lactamases catalyze the hydrolysis of most β-lactam antibiotics and hence represent a major clinical concern. The development of inhibitors for these enzymes is complicated by the diversity and flexibility of their substrate-binding sites, motivating research into their structure and function. In this study, we examined the conformational properties of the Bacillus cereus β-lactamase II in the presence of chemical denaturants using a variety of biochemical and biophysical techniques. The apoenzyme was found to unfold cooperatively, with a Gibbs free energy of stabilization (ΔG(0)) of 32 ± 2 kJ·mol(-1) For holoBcII, a first non-cooperative transition leads to multiple interconverting native-like states, in which both zinc atoms remain bound in an apparently unaltered active site, and the protein displays a well organized compact hydrophobic core with structural changes confined to the enzyme surface, but with no catalytic activity. Two-dimensional NMR data revealed that the loss of
Cephalosporins are the most commonly prescribed β-lactam antibiotics. Spectrophotometry is probably the most convenient analytical technique for routine analysis, because of its inherent simplicity, low cost and wide availability in quality control laboratories. Several papers have been presented in recent years regarding the development and validation for spectrophotometry methods for analysis of cephalosporins in pharmaceutical formulations. In this review article, various spectroscopic methods for analysis of cephalosporins are presented and discussed.
