Solifenacin succinate (Vesicare (R)), a novel muscarinic receptor antagonist for the treatment of overactive bladder (OAB) with symptoms of urge urinary incontinence, urgency, and urinary frequency, has been approved in more than 60 countries. In the course of continuing efforts to develop potent and bladder-selective muscarinic M-3 receptor antagonists, solifenacin was designed as one of conformationally restricted analogues of quinuclidin-3-yl benzhydrylcarbamate with little selectivity among muscarinic receptor subtypes. In preclinical studies, solifenacin exhibited a highly bladder-selective profile compared with other antimuscarinic agents. Clinically, solifenacin ameliorates all symptoms in OAB patients; and, in particular, it produces a significant decrease in urgency episodes, which is the principal symptom of OAB with good tolerability. In this article, the drug discovery and the process development of solifenacin succinate are described.

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 25152-84-5. Related Products of 25152-84-5.

Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. Application In Synthesis of (2E,4E)-Deca-2,4-dienal.

Four chiral, quaternary, N-methyl and N-benzyl derivatives of (R)- and (S)-quinuclidin-3-yl benzoates were synthesized and studied as substrates of horse serum butyrylcholinesterase (BChE). The k(cat) for the substrates decreased in the order (R)-N-methyl > (R)-N-benzyl (2.3-fold slower) much greater than (S)-N-methyl (70.5-fold slower reaction), while for the (S)-N-benzyl ester inhibition of the enzyme was observed. The kinetics of inhibition (K-a = 3.3 mum) indicated that binding to the catalytic site of BChE occurred. From the ratio of the k(cat)/K-M values of both enantiomers an enantiomeric excess of 95% was calculated for N-methyl derivatives. Thus, BChE is suitable as a biocatalyst for the resolution of racemic quaternary quinu-clidinium esters. In order to explain the experimental data, combined quantum chemical (HF/3-21G*) and semiempirical (PM3) calculations within the ONIOM scheme of the stable species in the acylation step were performed. Geometry optimizations were carried out for all benzoate esters for an assumed active site model of BChE. It was confirmed that hydrolysis is affected to an appreciable extent by a proper geometrical orientation of substrates at the choline subsite. The energies of the optimized systems were in good agreement with the experimental data. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003).

In the course of continuing efforts to develop potent and bladder-selective muscarinic M-3 receptor antagonists, quinuclidin-3-yl 1-aryl-1,2,3,4-tetrahydroisoquinoline-2-carboxylate derivatives and related compounds were designed as conformationally restricted analogues of quinuclidin-3-yl benzhydrylcarbamate (8). Binding assays with rat muscarinic receptor subtypes revealed that the quinuclidin-3-yl 1-aryl-1,2,3,4-tetrahydroisoquinoline-2-carboxylate derivatives showed high affinities for the M3 receptor, and selectivity for the M3 receptor over the M-2 receptor. Of these derivatives, (+)-(1S,3’R)-quinuclidin-3′-yl 1-phenyl-1,2,3,4-tetrahydroisoquinoline-2-carboxylate monohydrochloride (9b) exhibited almost the same inhibitory activity against bladder contraction to that of oxybutynin (1), and more than 10-fold selectivity for bladder contraction versus salivary secretion, demonstrating that 9b may be useful for the treatment of symptoms associated with overactive bladder without having side effects such as dry mouth.
