Simple one-pot process for the bioresolution of tertiary amino ester protic ionic liquids using subtilisin

An efficient hydrolase-catalyzed bioresolution of tertiary amino ester protic ionic liquids has been demonstrated. Protic ionic liquids have been prepared in one step from the corresponding tertiary amino alcohols by treatment with butyric anhydride. After bioresolution, unreacted esters can be easily separated from the corresponding alcohols by extraction with hexane Bioresolution of quinuclidin-3-yl butyrate has been performed with excellent selectivity.

QUINUCLIDIN-2-ENE – BASED MUSCARINIC ANTAGONISTS

A series of achiral 3-heteroaryl substituted quinuclidin-2-ene derivatives and related compounds have been synthesized by facile methods. The compounds were evaluated for muscarinic and antimuscarinic properties in receptor binding studies using (-)-[H-3]-QNB as the radioligand and ina functional assay using isolated guinea pig urinary bladder. 3-(2-Benzofuranyl)-quinuclidin-2-ene (15) displayed the highest M(1)-receptor affinity in the present series (K-i = 9.6 nM).

M-3 receptor antagonism by the novel antimuscarinic agent solifenacin in the urinary bladder and salivary gland

The antimuscarinic profile of the experimental drug solifenacin/YM905 [(+)-(1S,3’R)-quinuclidin-3′-yl 1-phenyl-1,2,3,4-tetrahydroisoquinoline-2-carboxylate] for the treatment of overactive bladder was compared with the commonly prescribed agent oxybutynin. In radioligand binding assays, pK(i) values of solifenacin for M-1, M-2, and M-3 receptors were 7.6, 6.9, and 8.0, respectively. These values for oxybutynin were 8.6 (M-1), 7.7 (M-2), and 8.9 (M-3). Solifenacin and oxybutynin antagonized the contractile effect of carbachol (CCh) on isolated guinea pig urinary bladder smooth muscle (detrusor), displaying the negative logarithm of antagonist apparent affinity constant (pK(b) value) of 7.1 for solifenacin and 7.4 for oxybutynin. To study the tissue selectivity between bladders and salivary glands, guinea pig detrusor and mouse submandibular gland cells were stimulated with CCh and monitored for intracellular Ca2+, as determined by Fura 2 fluorescence. Ca2+ mobilization of detrusor cells was inhibited equipotently by solifenacin (pK(i)=8.4) and oxybutynin (pK(i)=8.6), whereas that of the gland cells was antagonized less potently by solifenacin (pK(b)=7.4) than by oxybutynin (pK(b)=8.8), although the M-3 subtype mediated both cell responses. In anesthetized rats, solifenacin (63-2100 nmol kg(-1) or 0.03-1 mg kg(-1)) dose-dependently inhibited CCh-stimulated increases in urinary bladder pressure, while its inhibitory effects on salivation and bradycardia were apparent only at a dose of 2100 nmol kg(-1). In contrast, oxybutynin within a dose range of 77-770 nmol kg(-1) (0.03-0.3 mg kg(-1)) inhibited responses of the bladder and salivary gland slightly more potently than that of the heart. In addition, inhibitory effects of darifenacin indicated a major role Of M-3 receptors in the bladder and salivary gland. Therefore, M-3 receptor antagonism by solifenacin could be bladder-selective. This selectivity remains to be elucidated and may provide new approaches to the pharmacotherapy of overactive bladder.

Synthesis and antimuscarinic properties of quinuclidin-3-yl 1,2,3,4-tetrahydroisoquinoline-2-carboxylate derivatives as novel muscarinic receptor antagonists

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.

A practical chemoenzymatic process to access (R)-quinuclidin-3-ol on scale

(+/-)-3-Butyryloxyquinuclidinium butyrate 6 (2 M, 571 g/L), prepared from (+/-)-quinuclidin-3-ol 1 and butyric anhydride, undergoes enantioselective hydrolysis by an Aspergillus melleus protease {1.0% (w/v)} in water in the presence of Ca(OH)(2) to keep the reaction at pH 7 and trap butyric acid that is introduced as part of (+/-)-6 and generated by the enzymatic hydrolysis. After a 24 h period, extraction with n-heptane provides (R)-quinuclidin-3-yl butyrate 5a, which, on methanolysis with Na2CO3, is converted into (R)-1, a common pharmacophore of neuromodulators acting on muscarinic receptors, in 96% ee and 42% overall yield from (+/-)-1. The unwanted antipode (S)-1, which is extracted into n-butanol and purified via its hydrochloride salt in 89% ee and 40% overall yield from (+/-)-1, can be racemized by the catalysis of Raney Co at 140degreesC under an atmosphere of H, (5 kg/cm(2)) to regenerate (+/-)-1 in 97% yield.
