(+/-)-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.

New Advances in Chemical Research in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. Like 2442-10-6, Name is 1-Octen-3-yl Acetate. In a document, author is Liu, Shenping, introducing its new discovery. Synthetic Route of 2442-10-6.

Nicotinic acetylcholine receptors (nAChRs) form ligand-gated ion channels that mediate fast signal transmission at synapses. These receptors are members of a large family of pentameric ion channels that are of active medical interest. An expression system utilizing a chimerical construct of the N-terminal extracellular ligand binding domain of alpha7 type nAChR and the C-terminal transmembrane portion of 5HT3 type receptor resulted high level of expressions. Two ligand affinity chromatography purification methods for this receptor have been developed. One method relies on the covalent immobilization of a high affinity small molecule alpha7 nAChR agonist, (R)-5-(4-aminophenyl)-N-(quinuclidin-3-yl) furan-2-carboxamide, and the other uses mono biotinylated alpha-bungarotoxin, an antagonist, that forms a quasi-irreversible complex with alpha7 nAChR. Detergent solubilized alpha7/5HT(3) chimeric receptors were selectively retained on the affinity resins and could be eluted with free ligand or biotin. The proteins purified by both methods were characterized by gel electrophoresis, mass spectra, amino acid composition analysis, and N-terminal sequence determination. These analyses confirmed the isolation of a mature alpha7/5HT(3) receptor with the signal peptide removed. These results suggest a scalable path forward to generate multi-milligram amounts of purified complexes for additional studies including protein crystallization. (C) 2011 Elsevier Inc.

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.
