A new magnetically separable catalyst consisting of quinuclidin-3-thiol supported on propylsilane-functionalized silica-coated FeNi3 nanoparticles (FeNi3/quinuclidine) has been prepared. The synthesized catalyst was characterized by powder X-ray diffraction, transmission electron microscopy, vibrating sample magnetometry, thermogravimetric analysis, and Fourier transform infrared spectroscopy. The immobilized FeNi3/quinuclidine was shown to be an efficient heterogeneous catalyst for the synthesis of triazolo[1,2-a]indazole-triones under solvent-free conditions at room temperature. The catalyst is readily recovered by simple magnetic decantation and can be recycled several times with no significant loss of catalytic activity.

A series of 26 derivatives of the novel muscarinic antagonist 3-(2-benzofuranyl) quinuclidin-2-ene (1) has been synthesized and evaluated for muscarinic and antimuscarinic properties. The affinity of the compounds was determined by competition experiments in homogenates of cerebral cortex, heart, parotid gland, and urinary bladder from guinea pigs using (-)-[H-3]-3-quinuclidinyl benzilate as the radioligand, and the antimuscarinic potency was determined in a functional assay on isolated guinea pig urinary bladder using carbachol as the agonist. The 5-fluorobenzofuranyl derivative was slightly more potent than 1. The 7-bromo-substituted 8 displayed a 14-fold tissue selectivity ratio for muscarinic receptors in the cortex versus the parotid gland. Comparative molecular field analysis and quantitative structure-activity relationship models were developed for this series of substituted benzofuranyl derivatives.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.If you’re interested in learning more about 583-60-8.

Racemates as well as (R)- and (S)-enantiomers of 3-pivalamidoquinuclidine (PivQ) and 3-acetamidoquinuclidine (AcQ) were prepared. Their quaternary racemic and enantiomerically pure N-benzyl derivatives (BnlPivQ and BnlAcQ) were synthesized as well. The amides were tested as substrates and inhibitors of butyrylcholinesterase (BChE) from horse serum (EC 3.1.1.8). No hydrolysis was observed under the experimental conditions applied. On the contrary, inhibition of BChE by (R)- and (S)-enantiomers of N-benzylquinuclidinium amides of pivalic acid was observed. The (S)-BnlPivQ with K-i = 41.57 mu mol dm(-3) was 3-fold more potent inhibitor than the (R)-enantiomer. On the other hand, preliminary results indicated that both enantiomers of N-benzylquinuclidinum amides of acetic acid may possibly be inhibitors as well as activators depending on the concentrations of benzoylcholine (BzCh) used as a substrate of BChE.

To obtain novel muscarinic acetylcholine receptor (mAChR) antagonists, the enantiomers of the hybrid compounds 3-5, in which the quinuclidin-3-yloxy fragment of solifenacin and the 6,6-diphenyl-1,4dioxane-2-yl moiety of 2 linked by an ester or ether spacer were embedded in the same chemical entity, were prepared and evaluated for their affinity at the five mAChR subtypes (M-1-M-5). Stereochemistry and the nature of the linker between the quinuclidine moiety and the 1,4-dioxane nucleus play an important role on the affinities of the compounds. The presence of an ether bridge confers higher affinities for all mAChR subtypes to the ligand. Interestingly, the ether enantiomer (R,S)-5 shows the highest affinity at all mAChR subtypes with K-p(i) values similar to that of solifenacin at M-3 and higher at the other subtypes. Unlike solifenacin, it shows a preference for M-1 mAChR subtype with respect to the other subtypes. This compound, lacking a permanent positive charge on the nitrogen atom, can be a useful tool for the pharmacological study of mAChRs in the central nervous system. (C) 2017 Elsevier Masson SAS.

Eight chiral esters of quinuclidin-3-ol and butyric, acetic, pivalic and benzoic acid were synthesized as well as their racemic and chiral, quaternary N-benzyl derivatives. All racemic and chiral quaternary compounds were studied as substrates and/or inhibitors of horse serum butyrylcholinesterase (BChE). The best substrate for the enzyme was (R)-N-benzyl butyrate. The rates of hydrolysis decreased in order (R)-butyrate >> (R)-acetate (7-fold slower) > (R)-pivalate (8-fold slower) > (R)-benzoate (9-fold slower reaction), while (S)-N-benzyl esters were much poorer substrates (320 (butyrate) – 4360-fold slower (pivalate) than the appropriate (R)-enantiomer). For all (S)-N-benzyl esters excluding (S)-N-benzyl acetate inhibition constants were determined (K-a = 3.3-60 mu mol dm(-3)). The hydrolysis of racemic mixtures of N-benzyl esters proceeded 1.4 (for acetate) – 5.1 (for benzoate) times slower than that of pure (R)-enantiomers of the corresponding concentrations due to the inhibition with (S)-enantiomers. Change of the acyl moiety of the substrate effected both activity and stereoselectivity of the BChE.(doi: 10.5562/cca1829)

Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.Interested yet?
