N-acetylation of the heterocyclic amine batracylin by human liver. (1/255)

Batracylin (8-aminoisoindolo[1,2-b]quinazolin-12(10 H)-one; BAT) is a heterocyclic amine that exhibits antitumor activity in a number of in vivo and in vitro models. The acetyl product has been implicated in BAT toxicity in animals, cells, and bacteria. The ability of human N-acetyltransferase (NAT) to form this product was investigated. Nine human liver samples were analyzed for NAT1 and NAT2 genotypes. Seven of the samples possessed at least one NAT1*4 allele. Three samples contained one or more NAT2*4 allele and were classified as rapid acetylators. The remaining six had two alleles associated with the slow phenotype. NAT activities were evaluated with BAT, sulfamethazine (SMZ), a preferential substrate for human NAT2, and p-aminobenzoic acid, a substrate for NAT1. BAT activities in the nine donor samples ranged from 14.9 to 0.56 nmol/min/mg. The mean apparent K(m) values in rapid acetylators for BAT, SMZ, and p-aminobenzoic acid were 6.59 +/- 3.21, 278 +/- 69.4, and 31.2 +/- 12.5 microM, respectively. The apparent K(m) values for slow acetylators did not differ from the rapid acetylator phenotype. However, a significant difference in the apparent V(max) for BAT and SMZ was observed between rapid and slow acetylators. Comparing the apparent intrinsic clearance (V(max)/K(m)) for BAT and SMZ, a significant correlation (r(2) = 0.97, p <.001) was observed. These data demonstrate that BAT N-acetylation is similar to SMZ, and suggests that BAT is a preferential substrate for human NAT2. Thus, rapid acetylators would be more likely to develop toxicity when exposed to this drug.  (+info)

Antagonism of 5-hydroxytryptamine(4) receptors attenuates hyperactivity induced by cocaine: putative role for 5-hydroxytryptamine(4) receptors in the nucleus accumbens shell. (2/255)

The localization of 5-hydroxytryptamine(4) (5-HT(4)) receptors suggests their role in the regulation of dopamine (DA) neurotransmission, a speculation that has been supported by neurochemical studies. Mesolimbic DA systems play a prominent role in mediating the behavioral effects of the abused psychostimulant cocaine, and the intent of the present study was to assess the role of 5-HT(4) receptors in the control of spontaneous and cocaine-induced activity. Systemic administration of the 5-HT(4) receptor partial agonist 1-(4-amino-5-chloro-2-methoxyphenyl)-3-[1-butyl-4-piperidinyl]1-propa none hydrochloride (RS 67333; 0.0001-1 mg/kg) or the 5-HT(4) receptor antagonist 4-amino-5-chloro-2-methoxy-benzoic acid-(diethylamino)ethyl ester hydrochloride (SDZ 205,557; 0.0001-1 mg/kg) did not significantly alter spontaneous activity, whereas SDZ 205,557 significantly attenuated cocaine-induced horizontal activity and rearing. To test the hypothesis that cocaine-elicited behaviors were modulated by 5-HT(4) receptors in the nucleus accumbens (NAc) shell, two separate groups of male rats were implanted with bilateral cannulas aimed at the NAc shell. Intra-NAc shell microinjections of either RS 67333 (1 or 3 microgram/0.2 microliter/side) or SDZ 205,557 (1-5 microgram/0.2 microliter/side) did not alter spontaneous activity observed after a systemic saline injection but did significantly attenuate the hyperactivity induced by systemic cocaine injection (10 mg/kg). These results support an involvement of 5-HT(4) receptors, particularly those in the NAc shell, in the locomotor stimulatory effects of cocaine. Furthermore, these data suggest that 5-HT(4) receptors may regulate behavioral processes dependent on mesolimbic DA pathways and may provide a novel target for the development of medications useful in the treatment of both drug dependence and psychiatric disorders.  (+info)

Increased levels of dihydrofolate reductase in rifampin-resistant mutants of Bacillus subtilis. (3/255)

Several independent, spontaneous rifampin-resistant mutants of Bacillus subtilis were isolated and found to have an increased resistance to trimethoprim, an inhibitor of dihydrofolate reductase. This increased resistance in the rif mutants was the result of a specific threefold increase in the activity of dihydrofolate reductase, since six other enzymes examined remained unchanged. This increased level of dihydrofolate reductase and the trimethoprim resistance were cotransformed (100%) with the rif marker. These results suggest that the RNA polymerase is altered in its recognition of the gene that specifies dihydrofolate reductase.  (+info)

N-Acetylation of paraphenylenediamine in human skin and keratinocytes. (4/255)

Skin is the major target of allergic reactions to paraphenylenediamine (PPD). Such small molecules require activation to become immunogenic. The balance between activation and/or detoxification processes is critical for immunogenic potentials of compounds. Therefore, we investigated N-acetylation (NAT) capacities of human skin for PPD to gain a better understanding of its mechanisms of action. PPD is acetylated to monoacetyl-PPD (MAPPD), which in turn is acetylated to N,N'-diacetyl-PPD (DAPPD). This was found using cytosolic fractions from human skin (n = 9) and cultured normal human epidermal keratinocytes (n = 7). The cutaneous activities for MAPPD formation ranged from 0.41 to 3.68 nmol/mg/min (9-fold variation) and DAPPD formation from 0.65 to 3.25 nmol/mg protein/min (5-fold), respectively. Similar results were obtained with keratinocytes. NAT activities toward both substrates, PPD and MAPPD, were correlated in keratinocytes (r = 0.930), suggesting that the reactions were catalyzed by the same enzyme. Formation of MAPPD and DAPPD was competitively inhibited in the presence of p-aminobenzoic acid (300 microM), a typical NAT1 substrate, but not by sulfamethazine. These kinetic characteristics suggest that the acetylation of PPD in human skin and keratinocytes is predominantly attributable to the polymorphic NAT1, although both mRNAs (NAT1 and NAT2) are synthesized in human skin and keratinocytes. The metabolism of PPD by NAT1 in human skin and keratinocytes as well as the virtual absence of NAT2 activity may have important toxicological implications. In the case of PPD, our results emphasize that N-acetylation status may be a susceptibility factor for the development of an allergy to PPD.  (+info)

Substrate-dependent regulation of human arylamine N-acetyltransferase-1 in cultured cells. (5/255)

Arylamine N-acetyltransferase-1 (NAT1) is a polymorphically expressed enzyme that is widely distributed throughout the body. In the present study, we provide evidence for substrate-dependent regulation of this enzyme. Human peripheral blood mononuclear cells cultured in medium supplemented with p-aminobenzoic acid (PABA; 6 microM) for 24 h showed a significant decrease (50-80%) in NAT1 activity. The loss of activity was concentration-dependent (EC(50) approximately 2 microM) and selective because PABA had no effect on the activity of constitutively expressed lactate dehydrogenase or aspartate aminotransferase. PABA also induced down-regulation of NAT1 activity in several human cell lines grown at confluence. Substrate-dependent down-regulation was not restricted to PABA. Addition of other NAT1 substrates, such as p-aminosalicylic acid, ethyl-p-aminobenzoate, or p-aminophenol to peripheral blood mononuclear cells in culture also resulted in significant (P <.05) decreases in NAT1 activity. However, addition of the NAT2-selective substrates sulfamethazine, dapsone, or procainamide did not alter NAT1 activity. Western blot analysis using a NAT1-specific antibody showed that the loss of NAT1 activity was associated with a parallel reduction in the amount of NAT1 protein (r(2) = 0.95). Arylamines that did not decrease NAT1 activity did not alter NAT1 protein levels. Semiquantitative reverse transcriptase polymerase chain reaction of mRNA isolated from treated and untreated cells revealed no effect of PABA on NAT1 mRNA levels. We conclude that NAT1 can be down-regulated by arylamines that are themselves NAT1 substrates. Because NAT1 is involved in the detoxification/activation of various drugs and carcinogens, substrate-dependent regulation may have important consequences with regard to drug toxicity and cancer risk.  (+info)

Sensitive and selective determination of tetracaine and its metabolite in human samples by gas chromatography-mass spectrometry. (6/255)

A sensitive and reliable method was developed for the determination of tetracaine and its metabolite, p-butylaminobenzoic acid, in human samples. Tetracaine and the metabolite, effectively extracted using a liquid-liquid extraction procedure from 0.5 g of sample, were analyzed by gas chromatography-mass spectrometry. Tetracaine was analyzed without derivatization, and the metabolite was analyzed after tert-butylolimethylsilyl derivatization. Dibucaine and p-dimethylaminobenzoic acid were used as internal standards for tetracaine and the metabolite, respectively. The calibration curve for each compound was linear in the concentration range from 10 to 1,000 ng/0.5 g, and the lower limits of detection were 10 ng/g for tetracaine and 0.6 ng/g for the metabolite in whole blood and tissues. The accuracy and precision of the method were evaluated in whole blood and brain at the concentrations of 50 ng/0.5 g and 500 ng/0.5 g for tetracaine and 10 ng/0.5 g and 100 ng/0.5 g for the metabolite. The coefficients of variation ranged from 0.8 to 3.0% for tetracaine and 2.4 to 9.8% for the metabolite. We used this method to determine tetracaine and its metabolite in human whole blood and tissues of an autopsied patient who died during spinal anesthesia induced by tetracaine.  (+info)

Inhibition of the development of the cellular slime mould Dictyostelium discoideum by omega-aminocarboxylic acids. (7/255)

Four omega-aminocarboxylic acids - epsilon-aminocaproic acid (EACA), trans-4-aminomethylcyclohexane-1-carboxylic acid (t-AMCHA), p-aminomethylbenzoic acid (PAMBA) and omega-aminocaprylic acid (OACA) -- prevented fruiting body formation of the cellular slime mould Dictyostelium discoideum. At concentrations of 40 mM, 75 mM, 10 mM and 5 mM, respectively, they allowed aggregation but prevented all further development at 24 degrees C. At lower concentrations, EACA allowed fruiting body formation but with a reduced number of spores per fruiting body. Only t-AMCHA had a significant inhibitory effect on the growth of myxamoebae. EACA affected development only if it was present between 8 and 16 h after the cells were deposited on the filters. Its effect was enhanced by high salt concentrations and by higher temperature, and was also dependent on the manner in which the cells were grown. Only strains capable of axenic growth displayed this sensitivity to EACA, although strains carrying only one of the genetic markers for axenic growth (axe A) were partially sensitive.  (+info)

The effect of epsilon-aminocaproic acid on biochemical changes in the development of the cellular slime mould Dictyostelium discoideum. (8/255)

epsilon-Aminocaproic acid (EACA) inhibited the development of Dictyostelium discoideum strain AX2 after the aggregation stage. Biochemical changes that occurred early in development (loss of cellular protein, RNA and carbohydrate; increase in the specific activity of N-acetylglucosaminidase, alpha-mannosidase, threonine deaminase and leucine aminopeptidase) were not affected by concentrations of EACA which blocked development; but biochemical changes that occurred later (synthesis of carbohydrate, increase in the specific activity of UDP-glucose pyrophosphorylase) were inhibited. Spores from fruiting bodies formed in the presence of low concentrations of EACA were larger, more spherical and less able to survive heat treatment than spores from fruiting bodies of control (no EACA) cells.  (+info)

Malonaldehyde, a very reactive member of the homologous series of dialdehydes, is associated with the autoxidative deterioration of lipids. Its measurement, in autoxidized lipid systems is an expression of the extent of oxidation, in lipids. Malonaldehyde lends itself well to such determinations because of the sensitivity and specificity of its quantification in complex lipid systems. Complete knowledge of the formation of malonaldehyde in autoxidized lipids. is lacking. Such knowledge would undoubtedly promote a better understanding of lipid autoxidation mechanisms. In this investigation, a method for detecting malonaldehyde through the use of its reaction with p-aminobenzoic acid was developed. This was adapted for use in measuring malonaldehyde in lipids and in tissue samples. The reaction between p-aminobenzoic acid and malonaldehyde was partially characterized, and a mechanism for the formation of the reaction product was postulated. The quantification of malonaldehyde in lipid systems by ...

Microbial metabolites, including B complex vitamins contribute to diverse aspects of human health. Folate, or vitamin B9, refers to a broad category of biomolecules that include pterin, para-aminobenzoic acid (pABA), and glutamate subunits. Folates are required for DNA synthesis and epigenetic regulation. In addition to dietary nutrients, the gut microbiota has been recognized as a source of B complex vitamins, including folate. This study evaluated the predicted folate synthesis capabilities in the genomes of human commensal microbes identified in the Human Microbiome Project and folate production by representative strains of six human intestinal bacterial phyla. Bacterial folate synthesis genes were ubiquitous across 512 gastrointestinal reference genomes with 13% of the genomes containing all genes required for complete de novo folate synthesis. An additional 39% of the genomes had the genetic capacity to synthesize folates in the presence of pABA, an upstream intermediate that can be obtained
In deciding to use a medicine, the risks of using the medicine must be weighed against the good it will do. This is a decision you and your medical doctor, dentist, or nurse will make. For local anesthetics, the following should be considered:. Allergies - Tell your medical doctor, dentist, or nurse if you have ever had any unusual or allergic reaction to a local anesthetic or to epinephrine (e.g., Adrenalin). Also tell your medical doctor, dentist, nurse, or pharmacist if you are allergic to any other substances, such as sulfites or other preservatives, especially aminobenzoic acid (also called para-aminobenzoic acid [PABA]). Pregnancy - Local anesthetics have not been reported to cause birth defects in humans.. Use of a local anesthetic during labor and delivery may rarely cause unwanted effects. These medicines may increase the length of labor by making it more difficult for the mother to bear down (push). They may also cause unwanted effects in the fetus or newborn baby, especially if ...

Probiotic bacteria, mostly belonging to the genera Lactobacillus and Bifidobacterium, confer a number of health benefits to the host, including vitamin production. With the aim to produce folate-enriched fermented products and/or develop probiotic supplements that accomplish folate biosynthesis in vivo within the colon, bifidobacteria and lactobacilli have been extensively studied for their capability to produce this vitamin. On the basis of physiological studies and genome analysis, wild-type lactobacilli cannot synthesize folate, generally require it for growth, and provide a negative contribution to folate levels in fermented dairy products. Lactobacillus plantarum constitutes an exception among lactobacilli, since it is capable of folate production in presence of para-aminobenzoic acid (pABA) and deserves to be used in animal trials to validate its ability to produce the vitamin in vivo. On the other hand, several folate-producing strains have been selected within the genus Bifidobacterium, with a

Green Guidance The Truth in Beauty by Mindy Pennybacker, with reporting by Molly Rauch and Claire Gutierrez Not for nothing did our ancestors worship the sun, the source of Earths fertility and associated revels. What the ancients didnt understand, however, was the link between sun exposure and skin cancer. Whether you celebrate the season on a mountaintop or basking by the swimming hole, it pays to protect your skin. The key: read ingredient lists, and dont be caught napping at the expense of your or your childrens health. Sunscreens and Sunblocks. The skin is an absorptive organ, so it makes sense to use the least toxic products on it. Unfortunately, most sunscreens contain at least some iffy chemicals, including benzophenone, homosalate, and octy-methoxycinnamate, shown in animal tests to disrupt hormones and affect development of the brain and reproductive organs. PABA (para-aminobenzoic acid) has caused allergic reactions, and padimate-O and parsol 1789 (avobenzone) have the potential ...
A nutrient-rich diet contributes to a healthy head of hair. Without omega-3 fatty acids, hair is often dry and lifeless. Foods rich in biotin, copper, zinc, selenium, and para-aminobenzoic acid (PABA) may promote hair growth or slow hair loss. Note that foods containing raw egg should be avoided because raw egg binds biotin and prevents it from being absorbed by the body. (In any case, raw eggs should be avoided because of the risk of salmonella.) Please see related links for additional information on psoriasis and eczema, which may cause a flaking and itching scalp that contributes to hair problems. Mega-Recipes ...
People who are allergic to para-aminobenzoic acid (PABA) may also be allergic to Tessalon. This eMedTV discusses this possibility in more detail and describes several other important warnings and precautions to be aware of before taking Tessalon.
Amino esters are a class of local anesthetics. They are named for their ester bond (and are unlike amide local anaesthetics). Structurally, local anesthetics consist of three molecular components: a lipophilic part an intermediate aliphatic chain a hydrophilic (amine) part The chemical linkage between the lipophilic part and the intermediate chain can be of the amide-type or the ester-type, and is the general basis for the current classification of local anesthetics. Amino esters, in reference to anesthetic agents, are rapidly metabolized in the plasma by butyrlcholinesterase to para-aminobenzoic acid derivatives, then excreted in the urine. This suggests their very short half lives. Allergy is more likely to occur with ester-type agents, as opposed to amide-type. Amino ester-type include: Cocaine Procaine (Novocain) Tetracaine (Pontocaine) Benzocaine University of Texas Med School, Pharmacology Syllabus. Katzung. 10th edition. Chapter 26 ...
Is regional anesthesia indicated?. 1. Should you avoid using local anesthetics?. No. His allergic reaction could have been an intravascular injection, a reaction to epinephrine added to the solution, or a reaction to a derivative of para-aminobenzoic acid, from Novacaines ester local anesthetic.. 2. What determines potency of local anesthetics?. Lipid solubility determines potency. The higher the solubility, the more potent the agent is.. 3. What determines duration of action of local anesthetics?. Protein binding determines duration of action. The more the protein binding, the longer the duration of action.. 4. What determines onset of action of local anesthetics?. pKa determines onset of action. The closer the pKa is to the tissue pH, the faster the onset. All local anesthetics are weak bases, so those with a pKa near 7.4 have more molecules that are lipid-soluble and unionized.. ...

Nutrition is very important for the body. Even though hair and fingernails are just dead cells, they are an important indicator of the general well being of a person. Nutrition for the body is derived from the food we take. When the body does not receive the essential nutrients, or if it loses the ability to absorb nutrients from the food it receives, it causes the body to use up internal resources. This causes weakness in the body parts and is reflected in the skin, hair and fingernails. In order to have healthy hair and finger nails, it is very important to consume food that contains some major vitamins like vitamin A (produces healthy sebum in the scalp), vitamin C (antioxidant), vitamin E (improves scalp circulation), Biotin (produces Keratin), Inositol (keeps hair follicles healthy), Niacin (promotes scalp circulation) and pantothenic acid, Para-Aminobenzoic Acid, vitamin B6 and vitamin B12 that prevent graying and hair loss. Of these, vitamin E is found to have a significant influence on ...
Hair growth is more in the initial 30-40 years of an individuals life and much more slow after that. It is exceptionally hard to guarantee great hair growth all through however a decent and legitimate eating routine would go far in advancing hair growth. Hair growth might be influenced because of a few components like disregard, outer climate conditions, stress, drawn out diseases or stress. Dainty, fragile or split hair consumes a large chunk of the day to develop in light of the fact that it is anything but sound. The main pills vital for hair growth are: vitamin A produces solid sebum in the scalp, vitamin C cell reinforcement, vitamin E improves scalp course, Biotin produces Keratin, Inositol keeps hair follicles sound, Niacin advances scalp dissemination and pantothenic corrosive, Para-Aminobenzoic Acid, vitamin B6 and vitamin B12 that forestall turning gray and hair misfortune.. The most widely recognized food-based wellsprings of these pills are citrus organic products, green vegetables, ...
Biosynthetic Production of 4-Amino 4-Deoxychorismate (Adc) and [3R,4R]-4-Amino-3-Hydroxycyclohexa-1,5-Diene-1-Carboxylic Acid (3,4-Cha) - The invention relates to a process for the biosynthetic production of 4-amino-4-deoxychorismate (ADC) performed fermentatively in vivo with a 4-amino-4-deoxychorismate synthase, preferably a PabAB bipartite protein (which may be a fusion protein), at an increased level of activity, thereby obtaining a broth comprising ADC and 4-amino-4-deoxyprephenate (ADP), that are recovered. The invention also relates to a further process of converting the ADP into p-aminophenylalanine. The invention, moreover relates to biosynthetic production of [3R,4R]-4-amino-3-hydroxycyclohexa-1,5-diene-1-carboxylic acid (3,4-CHA), by concerted action of such 4-amino-4-deoxychorismate synthase and of an enzyme capable of converting isochorismate into [5S,6S]-5,6 dihydroxycyclohexa-1,3-diene-1-carboxylic acid (2,3-CHD), preferably a phenazine biosynthesis protein PhzD, including ...

The pab1 gene of the basidiomycete Coprinus cinereus encodes PABA synthase, necessary for para-aminobenzoic acid production. The C. cinereus protein is bifunctional with an N-terminal glutamine amidotransferase domain and a C-terminal chorismate amination domain. In most bacteria, these two functions are encoded in separate genes (e.g., pabA and pabB of E. coli). Fused PABA synthases have so far been detected in actinomycetes, Plasmodium falciparum, fungi and Arabidopsis thaliana. Phylogenetic analysis shows that the fused PAB sequences form a tight group that also includes uncharacterized PabB homologues from several bacteria. Unfused bacterial PabA proteins group with the glutamine amidotransferase subunits of bacterial anthranilate synthases, independent of organismal systematics, indicating a complex and perhaps independent evolutionary origin. In contrast, unfused PabB group and fused PabA/B proteins form a monophyletic group on a branch separate from the chorismate amination subunits of
The effect of the local anaesthetic, butacaine, on adenine nucleotide binding and translocation in rat liver mitochondria partially depleted of their adenine nucleotide content was investigated. The range of butacaine concentrations that inhibit adenine nucleotide translocation and the extent of the inhibition are similar to the values obtained for native mitochondria. Butacaine does not alter either the total number of atractyloside-sensitive binding sites of depleted mitochondria, or the affinity of these sites for ADP or ATP under conditions where a partial inhibition of the rate of adenine nucleotide translocation is observed. The data are consistent with an effect of butacaine on the process by which adenine nucleotides are transported across the mitochondrial inner membrane rather than on the binding of adenine nucleotides to sites on the adenine nucleotide carrier. The results are briefly discussed in relation to the use of local anaesthetics in investigations of the mechanism of adenine ...
Acetyl coenzyme A-dependent N-acetyltransferase and O-acetyltransferase activities were examined in liver cytosols derived from homozygous rapid acetylator C57BL/6J and A.B6 congenic inbred mouse strains, from homozygous slow acetylator A/J and B6.A congenic inbred mouse strains, and from the (C57BL/6J x A/J)F1 heterozygous acetylator hybrid mouse strain. Acetylator genotype-dependent N-acetyltransferase activity was exhibited for the N-acetylation of p-aminobenzoic acid, 2-aminofluorene, and 4-aminobiphenyl. In contrast, levels of isoniazid N-acetyltransferase and N-hydroxy-3,2-dimethyl-4-aminobiphenyl O-acetyltransferase activities in mouse liver cytosol appeared to be independent of the arylamine Nat acetylator gene. Although cytosolic N-acetyltransferase activities differed about 2-fold between the parental C57BL/6J and A/J strains for p-aminobenzoic acid, 2-aminofluorene, and 4-aminobiphenyl, the same N-acetyltransferase activities differed about 6-7-fold between the homozygous rapid ...
Antimetabolites may also be antibiotics, such as sulfanilamide drugs, which inhibit dihydrofolate synthesis in bacteria by competing with para-aminobenzoic acid (PABA).[7] PABA is needed in enzymatic reactions that produce folic acid, which acts as a coenzyme in the synthesis of purines and pyrimidines, the building-blocks of DNA. Mammals do not synthesize their own folic acid so they are unaffected by PABA inhibitors, which selectively kill bacteria. Sulfanilamide drugs are not like the antibiotics used to treat infections. Instead, they work by changing the DNA inside cancer cells to keep them from growing and multiplying. Antitumor antibiotics are a class of antimetabolite drugs that are cell cycle nonspecific. They act by binding with DNA molecules and preventing RNA (ribonucleic acid) synthesis, a key step in the creation of proteins, which are necessary for cancer cell survival.[8]. Anthracyclines are anti-tumor antibiotics that interfere with enzymes involved in copying DNA during the ...
Sulfacetamide is a sulfonamide antibiotic that blocks the synthesis of dihydrofolic acid by inhibiting the enzyme dihydropteroate synthase. Sulfacetamide is a competitive inhibitor of bacteria para-aminobenzoic acid (PABA), which is required for bacterial synthesis of folic acid1. It is active against Gram positive bacteria, Gram negative bacteria and Chlamydia. Mode of resistance is via the alteration of dihydropteroate synthase or alternative pathway for folic acid synthesis. ...

General. The safety and effectiveness of lidocaine depend on proper dosage, correct technique, adequate precautions, and readiness for emergencies. (See WARNINGS and ADVERSE REACTIONS). The lowest dosage that results in effective anesthesia should be used to avoid high plasma levels and serious adverse effects. Repeated doses of lidocaine may cause significant increases in blood levels with each repeated dose because of slow accumulation of the drug or its metabolites. Tolerance to elevated blood levels varies with the status of the patient. Debilitated, elderly patients, acutely ill patients, and children should be given reduced doses commensurate with their age and physical status. Lidocaine should also be used with caution in patients with severe shock or heart block. Lidocaine Hydrochloride Jelly USP, 2% should be used with caution in patients with known drug sensitivities. Patients allergic to para-aminobenzoic acid derivatives (procaine, tetracaine, benzocaine, etc.) have not shown cross ...
Abstract: Objective: The main objective of the present work was to grow 4-carboxyanilinium nitrate C7H8NO2+. NO3‾ semi-organic crystal by slow evaporation method and analyzed by various techniques. The positively charged carboxyanilinium cation and nitrate anion were existing in this crystal structure. Materials and Methods: 4-aminobenzoic acid, nitric acid, ethanol and deionized water were used in the crystal growth process as the raw materials. The semi-organic crystal of 4-carboxyanilinium nitrate is crystallized from the aqueous ethanol solution of 4-aminobenzoic acid mixed with aqueous solution of nitric acid in 2:1 stoichiometric ratio by slow evaporation technique. Results: The crystal lattice parameters and space group was obtained from the single crystal XRD study. The powder X-ray diffraction peaks were indexed using the INDX software. The FTIR and FT-Raman spectra of 4-carboxyanilinium nitrate crystal had been recorded at room temperature. The spectra were interpreted in terms of ...
A dihydropteroate synthase inhibitor is a drug that inhibits the action of dihydropteroate synthase. Most are sulfonamides.. In bacteria, antibacterial sulfonamides act as competitive inhibitors of the enzyme dihydropteroate synthase, DHPS. DHPS catalyses the conversion of PABA (para-aminobenzoate) to dihydropteroate, a key step in folate synthesis.[1] Folate is necessary for the cell to synthesize nucleic acids (nucleic acids are essential building blocks of DNA and RNA), and in its absence cells will be unable to divide. Hence the sulfonamide antibacterials exhibit a bacteriostatic rather than bactericidal effect.[2]. ...

Terrestrial plants, inter alia Eucalyptus trees, have evolved direct and indirect associations with microbes and insects. Each of these interactors produce specialized metabolites such as Abyssomycine C, a derivate of the para-aminobenzoic and folic acid biosynthesis (actinomyces), the polyketide Pederin, isolated from the intestine of the beetle Paederus spp, or numerous secondary allelopathic plant compounds that act as chemical defense and provide unique bio-fertilizer and pharmaceutical products. Their agonistic, antagonistic interactivities with the periphery environment foster, or negatively interfere with, food web functioning, plant fitness and adaptability. Independent plant, microbe and insect reserach provides only a limited view of the biotic interactions that dictate plant-microbe-insect community structure. The diversity inside insect intestines, in phyllo-, rhizo-spheres and soils of natural and agriculturally-used systems accommodate a wealth of secondary metabolite-producing
Deoxyribonucleate (DNA) preparations were extracted from Neisseria meningitidis (four isolates from spinal fluid and blood) and N. gonorrhoeae strains, all of which were resistant to sulfadiazine upon primary isolation. These DNA preparations, together with others from in vitro mutants of N. meningitidis and N. perflava, were examined in transformation tests by using as recipient a drug-susceptible strain of N. meningitidis (Ne 15 Sul-s Met+) which was able to grow in a methionine-free defined medium. The sulfadiazine resistance typical of each donor was introduced into the uniform constitution of this recipient. Production of p-aminobenzoic acid was not significantly altered thereby. Transformants elicited by DNA from the N. meningitidis clinical isolates were resistant to at least 200 μg of sulfadiazine/ml, and did not show a requirement for methionine (Sul-r Met+). DNA from six strains of N. gonorrhoeae, which were isolated during the period of therapeutic use of sulfonamides, conveyed lower degrees

Image acquisition. Albino Xenopus laevis tadpoles were reared as described previously (ORourke et al., 1994). Single neurons at different positions along the rostrocaudal axis of the tectum of stage 46-48 (Nieuwkoop and Faber, 1956) tadpoles were labeled by 1,1′-dioctadecyl-3,3,3′,3′-tetramethylindocarbocyanine perchlorate (DiI) (0.01% in absolute ethanol; Molecular Probes, Eugene, OR) iontophoresis. Positive current (1-10 nA) was applied in 3-10 pulses of 200 msec duration. Animals were screened to select those with single or well isolated brightly labeled neurons. Cells were imaged with a Noran XL laser scanning confocal attachment mounted on an upright Nikon Optiphot, using a 40× air lens (0.8 NA; Nikon). Optical sections were collected at 2 μm steps through the depth of the neuron. Each optical section was the average of eight frames.

Purpose: Emran et al (2010) reported that the amplitudes of the electroretinograms (ERGs) recorded from isolated eyes of larval zebrafish were normal throughout the day, but were almost absent after several hours of darkness at night. The purpose of our study was to confirm this circadian rhythm of the ERGs in living zebrafish.. Methods: Initially, zebrafish (Danio rerio) were kept in a 14:10 light:dark cycle (room fluorescent light, 9:00 to 23 hours). ERGs were elicited by stimulus intensities of 790 mW/m2 and durations of 1000 msec. The ERGs were recorded with an Ag/AgCl wire electrode that was inserted into a glass micropipette filled with E3 medium. A glasspipette electrode was positioned in the center of the cornea and a reference electrode was an Ag/AgCl pellet that placed beneath the larvae body. The zebrafish was anesthetized by 3-aminobenzoic acid methylester and placed on its side on a moisture sponge with one eye facing toward a light. We recorded ERGs of larval (5 days ...

The process of formation of a multilayer film on the ITO coated glass from sequential addition of PABA/RNA bilayers was observed with UV-Vis Spectroscopy as shown in Figure 3.34. The film growth observed with the deposition of additional bilayers suggests that the multilayer formation of PABA/RNA is reproducible with sequential deposition. All spectra exhibit an intense and sharp peak attributed to the w-tt and bipolaron band transitions. The bipolaron absorption band at 800 nm, associated with complexation of RNA with PABA, increases linearly with the number of PABA/RNA bilayers (Figure 3.34 inset). The linear relationship between absorbance and the number of deposited bilayers indicates that the deposition was reproducible from layer to layer, i.e., the amount of PABA adsorbed in each bilayer was the same. In addition to these results, multilayer formation was observed with ellipsometric and X-ray photoelectronic spectroscopy. The linear increase in film thickness with number of PABA/RNA ...
