Involvement of two plasmids in the degradation of carbaryl by Arthrobacter sp. strain RC100. (1/1210)

A bacterium capable of utilizing carbaryl (1-naphthyl N-methylcarbamate) as the sole carbon source was isolated from carbaryl-treated soil. This bacterium was characterized taxonomically as Arthrobacter and was designated strain RC100. RC100 hydrolyzes the N-methylcarbamate linkage to 1-naphthol, which was further metabolized via salicylate and gentisate. Strain RC100 harbored three plasmids (designated pRC1, pRC2, and pRC3). Mutants unable to degrade carbaryl arose at a high frequency after treating the culture with mitomycin C. All carbaryl-hydrolysis-deficient mutants (Cah-) lacked pRC1, and all 1-naphthol-utilization-deficient mutants (Nat-) lacked pRC2. The plasmid-free strain RC107 grew on gentisate as a carbon source. These two plasmids could be transferred to Cah- mutants or Nat- mutants by conjugation, resulting in the restoration of the Cah and Nah phenotypes.  (+info)

Efficacy and safety of rivastigmine in patients with Alzheimer's disease: international randomised controlled trial. (2/1210)

OBJECTIVES: To assess the effects of rivastigmine on the core domains of Alzheimer's disease. DESIGN: Prospective, randomised, multicentre, double blind, placebo controlled, parallel group trial. Patients received either placebo, 1-4 mg/day (lower dose) rivastigmine, or 6-12 mg/day (higher dose) rivastigmine. Doses were increased in one of two fixed dose ranges (1-4 mg/day or 6-12 mg/day) over the first 12 weeks with a subsequent assessment period of 14 weeks. SETTING: 45 centres in Europe and North America. PARTICIPANTS: 725 patients with mild to moderately severe probable Alzheimer's disease diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, and the criteria of the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association. OUTCOME MEASURES: Cognitive subscale of the Alzheimer's disease assessment scale, rating on the clinician interview based impression of change incorporating caregiver information scale, and the progressive deterioration scale. RESULTS: At the end of the study cognitive function had deteriorated among those in the placebo group. Scores on the Alzheimer's disease assessment scale improved in patients in the higher dose group when compared with patients taking placebo (P<0.05). Significantly more patients in the higher dose group had improved by 4 points or more than had improved in the placebo group (24% (57/242) v 16% (39/238)). Global function as rated by the clinician interview scale had significantly improved among those in the higher dose group compared with those taking placebo (P<0.001), and significantly more patients in the higher dose group showed improvement than did in the placebo group (37% (80/219) v 20% (46/230)). Mean scores on the progressive deterioration scale improved from baseline in patients in the higher dose group but fell in the placebo group. Adverse events were predominantly gastrointestinal, of mild to moderate severity, transient, and occurred mainly during escalation of the dose. 23% (55/242) of those in the higher dose group, 7% (18/242) of those in the lower dose group, and 7% (16/239) of those in the placebo group discontinued treatment because of adverse events. CONCLUSIONS: Rivastigmine is well tolerated and effective. It improves cognition, participation in activities of daily living, and global evaluation ratings in patients with mild to moderately severe Alzheimer's disease. This is the first treatment to show compelling evidence of efficacy in a predominantly European population.  (+info)

Treatment with amprenavir alone or amprenavir with zidovudine and lamivudine in adults with human immunodeficiency virus infection. AIDS Clinical Trials Group 347 Study Team. (3/1210)

Amprenavir is a human immunodeficiency virus (HIV) protease inhibitor with a favorable pharmacokinetic profile and good in vitro activity. Ninety-two lamivudine- and protease inhibitor-naive individuals with >/=50 CD4 cells/mm3 and >/=5000 HIV RNA copies/mL were assigned amprenavir (1200 mg) alone or with zidovudine (300 mg) plus lamivudine (150 mg), all given every 12 h. After a median follow-up of 88 days, the findings of a planned interim review resulted in termination of the amprenavir monotherapy arm. Among 85 subjects with confirmed plasma HIV RNA determination, 15 of 42 monotherapy versus 1 of 43 triple-therapy subjects had an HIV RNA increase above baseline or 1 log10 above nadir (P=.0001). For subjects taking triple therapy at 24 weeks, the median decrease in HIV RNA was 2.04 log10 copies/mL, and 17 (63%) of 27 evaluable subjects had <500 HIV RNA copies/mL. Treatment with amprenavir, zidovudine, and lamivudine together reduced the levels of HIV RNA significantly more than did amprenavir monotherapy.  (+info)

A 1-year multicenter randomized double-blind comparison of repaglinide and glyburide for the treatment of type 2 diabetes. Dutch and German Repaglinide Study Group. (4/1210)

OBJECTIVE: Repaglinide is a newly developed oral blood glucose-lowering agent that exerts its effect by stimulating insulin secretion. This multicenter study was designed to compare the efficacy and safety of this drug with glyburide in a 1-year randomized double-blind study of outpatients with type 2 diabetes. RESEARCH DESIGN AND METHODS: A total of 424 subjects (154 women, 270 men) participated and had the following characteristics: age, 61 +/- 9 years; duration of diabetes. 8 years (range 0.5-35); BMI, 28.3 +/- 3.5 kg/m2; HbA1c, 7.1 +/- 1.4%; and fasting plasma glucose, 10.8 +/- 3.1 mmol/l. The majority of the subjects (91%) were previously treated with sulfonylurea, alone or in combination with metformin. The patients were randomized to a 2:1 ratio of repaglinide (0.5-4 mg t.i.d.) or glyburide (1.75-10.5 mg daily) treatment. The study protocol included a screening visit to assess patient eligibility; a titration period of 6-8 weeks, during which the dosages of repaglinide and glyburide were optimized; and a subsequent 12-month treatment period on fixed, optimal dosages. RESULTS: The trial was completed by 320 subjects, 211 (74%) in the repaglinide and 109 (78%) in the glyburide group. HbA1c initially decreased in both groups and then increased during the second half-year of the maintenance period to a similar extent in the repaglinide and glyburide subjects (0.58 and 0.45% vs. at screening, respectively). In the small group of subjects who previously controlled their condition with diet only (n = 37), a sustained improvement of metabolic control could be observed with both drugs, which was slightly better with glyburide than with repaglinide (theta HbA1c -2.4 vs. -1.0%; P < 0.05). The same trends were seen with fasting plasma glucose. There were no changes in serum lipids. Over the course of the study, 15% of the repaglinide-treated and 13% of glyburide-treated subjects withdrew due to adverse events, mostly hyperglycemia. No differences in adverse events between both drugs were reported. There were no differences in incidences of hypoglycemia. CONCLUSIONS: Repaglinide is a safe and efficacious oral blood glucose-lowering agent, with a potency similar to that of glyburide. Its rapid onset of action and hepatic clearance allows meal-related administration, including in subjects with impaired kidney function.  (+info)

Structural and mechanistic aspects of transcriptional induction of cytochrome P450 1A1 by benzimidazole derivatives in rat hepatoma H4IIE cells. (5/1210)

The effect of several structurally different benzimidazole compounds on CYP1A1 expression at the transcriptional, mRNA and protein levels was investigated in the rat hepatoma H4IIE cell line. Omeprazole, thiabendazole, carbendazim, 2-mercaptobenzimidazole and 2-mercapto-5-methoxybenzimidazole caused a dose-dependent increase in CYP1A1 protein levels that reached maximum effect at 250 microm, as measured by Western blot. In addition, hydroxyomeprazole, 2-aminobenzimidazole and 2-mercapto-5-nitro-benzimidazole caused a notable increase in CYP1A1 protein expression, whereas 5-O-desmethylomeprazole, 2-hydroxybenzimidazole, 2-benzimidazole propionic acid and 5-benzimidazole carboxylic acid were ineffective. Thus, benzimidazole substituted with a thiol or an amino group in the 2-position were active inducers. Northern blot analysis confirmed an extensive increase of CYP1A1 mRNA induced by omeprazole and 2-mercapto-5-methoxybenzimidazole which was 32% and 49% of maximal induction by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) respectively, whereas thiabendazole and carbendazim showed approximately 15% increase as compared to TCDD. Transient transfection of H4IIE cells, with a XRE-pGL3 reporter gene construct revealed a 2.3-4.3-fold induction by carbendazim, thiabendazole, and 2-mercapto-5-methoxybenzimidazole as compared to a 3.3- and 23-fold induction by omeprazole and TCDD, respectively. Thus, these data indicate that the benzimidazoles utilize the aryl hydrocarbon receptor-arnt-XRE-mediated signal-transduction pathway for induction of the CYP1A1 gene.  (+info)

A common pharmacophore for cytotoxic natural products that stabilize microtubules. (6/1210)

Taxol (paclitaxel), a complex diterpene obtained from the Pacific yew, Taxus brevifolia, is arguably the most important new drug in cancer chemotherapy. The mechanism of cytotoxic action for paclitaxel-i.e., the stabilization of microtubules leading to mitotic arrest-is now shared by four recently identified natural products, eleutherobin, epothilones A and B, and discodermolide. Their ability to competitively inhibit [3H]paclitaxel binding to microtubules strongly suggests the existence of a common binding site. Recently, we have developed nonaromatic analogues of paclitaxel that maintain high cytotoxicity and tubulin binding (e.g., nonataxel). We now propose a common pharmacophore that unites paclitaxel, nonataxel, the epothilones, eleutherobin, and discodermolide, and rationalizes the extensive structure-activity relationship data pertinent to these compounds. Insights from the common pharmacophore have enabled the development of a hybrid construct with demonstrated cytotoxic and tubulin-binding activity.  (+info)

Pharmacological activities of TEI-8362, a novel inhibitor of human neutrophil elastase. (7/1210)

1. TEI-8362, 4-(N-(3-((3-carboxypropyl)amino)-8-methyl-1-oxo-4-azaisochromen-6- yl)carbamoyl)-4-((phenylmethoxy)carbonylamino)butanoic acid (C26H28N4O9) is a novel inhibitor of human neutrophil elastase (HNE). We evaluated its pharmacological profile in vitro and in vivo. 2. TEI-8362 demonstrated potent inhibition of HNE with a Ki value of 1.38 x 10(-9) M. Its selectivity for HNE among a variety of proteases ranged from 163 fold to 68,000 fold in favour of HNE. 3. The pulmonary haemorrhage that occurred after i.t. instillation of HNE to hamsters was inhibited by either i.t., i.v., or inhalant administration of TEI-8362. 4. Intratracheal administration of lipopolysaccharide induced pulmonary neutrophilia. Twenty-four hours after lipopolysaccharide administration, the additional treatment with formyl-methionyl-leucyl-phenylalanine resulted in a specific neutrophil-dependent acute lung injury. In this model, lung injury was significantly attenuated by i.t., i.v., or inhalant administration of TEI-8362. 5. These pharmacological actions of TEI-8362 suggest that this drug has therapeutic value in the treatment of destructive lung diseases due to neutrophils.  (+info)

Does an association between pesticide use and subsequent declines in catch of Atlantic salmon (Salmo salar) represent a case of endocrine disruption? (8/1210)

Historical aerial applications of the insecticide Matacil 1.8D provide an opportunity to look for potential effects of the endocrine disrupting compound 4-nonylphenol (4-NP) on Atlantic salmon (Salmo salar) populations. Matacil 1.8D contained the carbamate insecticide aminocarb, with 4-NP as primary solvent. Between 1975 and 1985 Matacil 1.8D was applied to forests in Atlantic Canada to control damage from the spruce budworm (Choristoneura fumiferana). After spraying, estimated concentrations of 4-NP in water fell within a range in which estrogenic effects might be anticipated. The spraying coincided with final stages of smolt development in salmon. Salmon catch data were evaluated considering effects on survival of the smolt stage. There was a significant negative relationship between the returns of salmon and the proportion of tributaries sprayed within the Restigouche River drainage basin in 1977. There was also a broader event of unusually heavy salmon smolt mortality in 1977, which contains a significant relationship indicating that where Matacil 1.8D spraying occurred, the smolt mortality increased. For 16 rivers exposed to spraying between 1973 and 1990, a significant proportion (p<0.005) of the lowest salmon catches coincided with Matacil 1.8D spraying. A decline coinciding with the use of Matacil 1.8D was also apparent in blueback herring (Alosa aestivalis) catches in New Brunswick. Because similar relationships were not evident for Matacil 1.8F or fenitrothion, neither of which were formulated with 4-NP, we hypothesize that the 4-NP in Matacil 1.8D was the causal agent. Concentrations of 4-NP described here are within current ranges encountered in industrial effluents and municipal sewage outfalls.  (+info)

Fatty acid amide hydrolase (FAAH) is responsible for hydrolysis of endocannabinoid, anandamide (AEA), and N-acyl ethanolamines such as palmitoylethanolamine (PEA) and N-oleoylethanolamide (OEA). Genetic deletion or pharmacological inactivation of FAAH shows site-specific elevation of AEA that plays a role in the modulation of pain and other neurodegenerative disorders. The review elaborates recent progress and current status of diverse structural classes of reversible and irreversible FAAH inhibitors. The discussion also addresses ligand-enzyme active site interactions and mechanism of enzyme inactivation, emerging approaches to novel FAAH inhibitors, and ongoing efforts to address gaps in therapeutic utility of FAAH inhibitors.
As a member of the transient receptor potential (TRP) ion channel superfamily, the ligand-gated ion channel TRPA1 has been implicated in nociceptive function and pain states. The endogenous ligands that activate TRPA1 remain unknown. However, various agonists have been identified, including environmental irritants (e.g., acrolein) and ingredients of pungent natural products [e.g., allyl isothiocyanate (ITC), cinnamaldehyde, allicin, and gingerol]. In general, these agents are either highly reactive, nonselective, or not potent or efficacious, significantly limiting their utilities in the study of TRPA1 channel properties and biological functions. In a search for novel TRPA1 agonists, we identified 3 -carbamoylbiphenyl-3-yl cyclohexylcarbamate (URB597), a potent and systemically active inhibitor of fatty acid amide hydrolase (FAAH). This enzyme is responsible for anandamide degradation and therefore has been pursued as an antinociceptive and antiepileptic drug target. Using Ca influx assays and patch

0015]Due to the relative stability amides in vivo, N-acylation of amines to give amide prodrugs has only been used to a limited extent (H. Bundgaard H & M. Johansen, J Pharm Sci., 69 (1980) 44-6). For the same reason, the utility of carbamates as prodrug derivatives for amines is also limited. Introducing an enzymatically hydrolyzable ester function into the carbamate structure may evade such problem. N-(acyloxyalkoxycarbonyl) derivatives of primary or secondary amines are likely to be transformed to the parent amine in vivo (J. Alexander, R. Cargill, S. R. Mohelson and H. Schwamm, J. Med. Chem., 31 (1988) 316-22; U. S. Gates & A. J. Repta, Int. J. Pharm., 40 (1987) 249-55). Enzymatic based hydrolysis of such ester moiety in those derivatives will lead to a (hydroxy-alkoxy)carbonyl derivative which spontaneously decomposes into parent amine via an unstable carbamic acid. Acyloxy-alkyl carbamates as shown in Table 5 and Example 11 are promising biolabile prodrugs for amino functional drugs, since ...

Applications were made from growth stages R1 (flowering) to R3 (podset) (2), with more than 60% of the trials receiving a pyraclostrobin application at growth stage R3. Locations of fungicide strips were recorded with on-board GPS systems in all 14 trials that received aerial fungicide applications and in approximately 90% of the trials that received ground fungicide applications. In the remaining 10% of the trials, farmers flagged the strips during fungicide applications and recorded GPS coordinates of each strip later during the growing season. Treatments were alternated within each trial to help farmers accommodate treatment applications, allow researchers to verify treatment locations and conduct analysis of yield responses observed at both field and within-field (spatial observations) levels. All discussions in this article are focused only on field-level mean yield responses.

In case of emergency-There may be a time when you need emergency help for a problem caused by your diabetes. You need to be prepared for these emergencies. It is a good idea to wear a medical identification (ID) bracelet or neck chain at all times. Also, carry an ID card in your wallet or purse that says that you have diabetes and a list of all of your medicines.. Too much repaglinide can cause low blood sugar (hypoglycemia). Low blood sugar also can occur if you use repaglinide with another antidiabetic medicine, delay or miss a meal or snack, exercise more than usual, drink alcohol, or cannot eat because of nausea or vomiting. Symptoms of low blood sugar must be treated before they lead to unconsciousness (passing out). Different people may feel different symptoms of low blood sugar. It is important that you learn which symptoms of low blood sugar you usually have so that you can treat it quickly.. Symptoms of low blood sugar include anxiety; behavior change similar to being drunk; blurred ...
Section 1 of this thesis contains an introduction to method development in organic synthesis, multicomponent reactions, sulfonyl azides, tracer development in 11C chemistry and the biological target.. Section 2 describes the use of sulfonyl azides in carbonylative chemistry. Paper I covers development of a diazotransfer protocol. In total, 30 arylsulfonyl azides were synthesised from primary sulfonamides (20-90% yield). 15N mechanistic studies were carried out and in Paper II, the products were converted into sulfonamides, sulfonylureas and sulfonyl carbamates (19-90% yield). For ureas and carbamates, a two-chamber protocol was employed to release CO from Mo(CO)6. 15N mechanistic studies showed that the sulfonamides were formed by direct displacement of azide.. Section 3 covers imaging and biological studies of the angiotensin II receptor subtype 2 (AT2R). In Paper III, 12 11C-sulfonyl carbamates were prepared in isolated radiochemical yields of 3-51% via Rh(I)-mediated carbonylation. The first ...

Repaglinide is presently recommended by the U.S. Food and Drug Administration as a clinical CYP2C8 probe, yet current in vitro and clinical data are inconsistent concerning the role of this enzyme in repaglinide elimination. The aim of the current study was to perform a comprehensive investigation of repaglinide metabolic pathways and assess their contribution to the overall clearance. Formation of four repaglinide metabolites was characterized using in vitro systems with differential complexity. Full kinetic profiles for the formation of M1, M2, M4, and repaglinide glucuronide were obtained in pooled cryopreserved human hepatocytes, human liver microsomes, human S9 fractions, and recombinant cytochrome P450 enzymes. Distinct differences in clearance ratios were observed between CYP3A4 and CYP2C8 for M1 and M4 formation, resulting in a 60-fold M1/M4 ratio in recombinant (r) CYP3A4, in contrast to 0.05 in rCYP2C8. Unbound Km values were within 2-fold for each metabolite across all in vitro ...

Repaglinide can cause low blood sugar (hypoglycemia) especially if you are taking other medicines for diabetes. Consuming large quantities of alcohol, not getting enough calories from food, or doing unusually heavy exercise may also lead to low blood sugar. Symptoms may include chills, cold sweat, dizziness, drowsiness, shaking, fast heartbeat, weakness, headache, fainting, tingling of the hands or feet, or hunger. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you dont have these reliable forms of glucose, raise your blood sugar quickly by eating a quick source of sugar such as table sugar, honey, candy, or drinking a glass of fruit juice or non-diet soda.
