The synthesis of racemic and enantiomerically pure 3-butanamidoquinuclidines ((+/-)-Bu, (R)-Bu and (S)-Bu), (1-3) and 3-benzamidoquinuclidines ((+/-)-Bz, (R)-Bz, and (S)-Bz), (4-6) is described. The N-quaternary derivatives, N-benzyl-3-butatiamidoquinuclidinium bromides ((+/-)-Bn1Bu, (R)-Bn1Bu and (S)-Bn1Bu), (7-9) and N-betizyl-3-beiizaimidoquinuclidiniuim bromides ((+/-)-Bn1Bz, (R)-Bn1Bz and (S)-Bn1Bz), (10-12) were subsequently synthesized. The interaction of the four enantiomerically pure quaternary derivatives with horse serum butyrylcholinesterase (BChE) was tested. All tested Compounds inhibited the enzyme. The best inhibitior of the enzyme was (S)-Bn1Bz with a K-i = 3.7 mu M. The inhibitor potency decreases in order (S)-Bn1Bz > (R)-Bn1Bz > (R)-Bn1Bu > (S)Bn1Bu. (c) 2006 Elsevier Inc.

1 To better understand how it decreases plasma cholesterol and triglyceride, we evaluated the effect of YM-53601 ((E-2-[2-fluoro-2-(quinuclidin-3-ylidene) ethoxy]-9H-carbozole monohydrochloride) on the clearance rate of low density lipoprotein (LDL) and very low density lipoprotein (VLDL) in hamsters. 2 Treatment with YM-53601 at 50 mg kg(-1) for 5 days in hamsters fed a normal diet enhanced the disappearance of 1,1′-Dioctadecyl-3,3,3′,3′-tetramethylindocarbocyanine perchlorate (DiI)-VLDL and DiI-LDL. This effect on DiI-LDL was lost in the early phase after DiI-methyl(met)-LDL, chemically modified to block LDL receptor binding, was injected in hamsters, but was retained in the late phase. Pre-treatment with prolamine sulphate, which inhibits the activity of LPL, also failed to enhance DiI-VLDL clearance rate by YM-53601. 3 Even on single oral administration at 30 mg kg(-1), YM-53601 enhanced the disappearance of the high concentration of plasma triglyceride after injection of intrafat, an emulsion of fat. Plasma triglyceride was significantly decreased as soon as 1 h after single administration of YM-53601 in hamsters fed a normal diet. 4 These results indicate that the decrease in plasma total cholesterol and triglyceride after the treatment with YM-53601 is due to its enhancement of the clearance rate of LDL and VLDL, respectively. Moreover, YM-53601 may be effective in decreasing plasma triglyceride levels early in the course of treatment of hypertriglyceridaemia in humans.

Purpose: Although antimuscarinic treatment is indicated for overactive bladder, many patients discontinue it because of dry mouth. Of available antimuscarinics oxybutynin is associated with the highest dry mouth rate. We compared the safety and tolerability of 5 mg solifenacin vs 15 mg oxybutynin immediate release. Materials and Methods: At 12 Canadian centers a total of 132 patients with overactive bladder symptoms (greater than 1 urgency episode per 24 hours, and 8 or greater micturitions per 24 hours) were randomized to 5 mg solifenacin once daily or 5 mg oxybutynin 3 times daily for 8 weeks. The primary end point was the incidence and severity of dry mouth reported after direct questioning. Efficacy end points (3-day diary documented changes in urgency, frequency, incontinence, nocturia and voided volume), and changes on the Patient Perception of Bladder Condition scale and the Overactive Bladder Questionnaire were evaluated secondarily. Results: Of patients on solifenacin vs oxybutynin immediate release 35% vs 83% reported dry mouth (p <0.0001). Of patients reporting dry mouth severity was graded moderate by 13% and 42% of those on solifenacin and oxybutynin immediate release, and severe by 13% and 28%, respectively (p = 0.001). Patients in each group showed improvements in efficacy end points, and Patient Perception of Bladder Condition scale and Overactive Bladder Questionnaire scores from baseline to treatment end. Conclusions: Significantly fewer patients on 5 mg solifenacin once daily reported dry mouth vs those receiving 5 mg oxybutynin immediate release 3 times daily. Significantly fewer patients on solifenacin reported moderate/severe dry mouth. Significantly fewer patients on solifenacin withdrew from study due to dry mouth and there were significantly fewer overall adverse events. Solifenacin and oxybutynin immediate release were efficacious in decreasing efficacy end points, and improved Patient Perception of Bladder Condition scale and Overactive Bladder Questionnaire results from baseline to treatment end. Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 6413-10-1.

The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In a document, author is Naito, R, introducing its new discovery. Electric Literature of 6413-10-1.

A novel series of biphenylylcarbamate derivatives were synthesized and evaluated for binding to M-1, M-2 and M-3 receptors and for antimuscarinic activities. Receptor binding assays indicated that biphenyl-2-ylcarbamate derivatives had high affinities for M-1 and M-3 receptors and good selectivities for M-3 receptor over M-2 receptor, indicating that the biphenyl-2-yl group is a novel hydrophobic replacement for the benzhydryl group in the muscarinic antagonist field. In this series, quinuclidin-1-yl biphenyl-2-ylcarbamate monohydrochloride (81, YM-46303) exhibited the highest affinities for M-1 and M-3 receptors, and selectivity for M-3 over M-2 receptor. Compared to oxybutynin, YM-46303 showed approximately ten times higher inhibitory activity on bladder pressure in reflexly-evoked rhythmic contraction, and about 5-fold greater selectivity for urinary bladder contraction against salivary secretion in rats. Moreover, selective antagonistic activity was also observed in vitro. Further evaluation of antimuscarinic effects on bradycardia and presser in pithed rats, and on tremor in mice, showed that YM-46303 can be useful for the treatment of urinary urge incontinence as a bladder-selective M-3 antagonist with potent activities and fewer side effects.

Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. Like 6413-10-1, Name is Ethyl 2-(2-methyl-1,3-dioxolan-2-yl)acetate. In a document, author is BESIDSKY, Y, introducing its new discovery. Reference of 6413-10-1.

Cyclocondensation of 2-(2-cyano-1,2-diphenylethyl)quinuclidin-3-one 1 in the presence of sulfuric acid gave an intramolecular phenylation instead of lactam formation. The cyclic product was hydrogenated to give 6-carbamoyl-5-phenyl-2,3,4a,5,6,10b-hexahydro-1H-1,4-ethanobenzo- [f]quinoline. On treatment with LiAIH(4) the carbamoyl group was stereospecifically replaced by a hydroxy group. The alcohol was acetylated and the structure was confirmed by X-ray crystallography. The hydroxylation reaction is believed to proceed via a carbonitrile intermediate. In the presence of air the nitrile can be converted to a ketone which is then reduced to the alcohol with an overall retention of configuration.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 6413-10-1. Reference of 6413-10-1.
