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.

Both enantiomers of quinuclidin-3-yl benzoate (RQBz and SQBz) were synthesized in order to examine the stereoselectivity of the hydrolysis of these esters catalyzed by horse serum butyrylcholinesterase (BChE). The hydrolysis of benzoylcholine (BzCh) was also studied in order to determine the influence of the alcohol part of the esters upon the kinetics. The k(cat) value for the substrates decreased in order BzCh > RQBz (4-fold slower) much greater than SQBz (76-fold slower reaction). K-M values determined for quinuclidinium substrates revealed that the binding affinity of RQBz (0.28 mm) is approximately 2-fold lower than that of SQBz (0.13 mM) towards BChE. From the ratio of the enantiomeric k(cat)/K-M values, an enantiomeric excess of 78% was calculated, indicating that the resolution of racemic quinuclidin-3-yl benzoate can be achieved by hydrolysis with BChE. The orientations of all the studied benzoate esters and butyrylcholine (BuCh) in the active site of human BChE were proposed by flexible ligand docking with AutoDock 3.0. Analyses of the Michaelis complexes obtained revealed that there are numerous similar close contacts in the active site. The main difference in binding of quinuclidinium and choline esters was found in the ammonium electrostatic region which includes cation-pi interaction of the ammonium moiety of substrates with the indole ring of Trp(84). The important cation-pi interaction with Trp(84) was lowest in the case of the S-enantiomer of QBz, which might be the main explanation for the slowest rate of hydrolysis of that compound.

1 The aim of this study was to establish an experimental model of the escape phenomenon, in which plasma cholesterol, initially reduced by a 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) reductase inhibitor such as pravastatin, increases again on long-term administration. We also evaluated the efficacy of YM-53601 ((E)-2-[2-fluoro-2- (quinuclidin-3-ylidene) ethoxy]-9H-carbazole monohydrochloride), a squalene synthase inhibitor, in this model. 2 Pravastatin inhibited cholesterol biosynthesis in hamster primary hepatocytes (IC50, 14 nM). After pre-treatment with pravastatin, in contrast, almost no effect on cholesterol biosynthesis was seen. 3 In hamsters fed a high fat diet, 3 mg kg(-1) pravastatin for 9 days decreased plasma non-HDL cholesterol (total cholesterol-high density lipoprotein cholesterol) (P<0.01), but this effect was lost between 17 and 27 days of treatment, accompanied by an increase in HMG-CoA reductase activity. No such increase in plasma non-HDL cholesterol was seen with YM-53601 at 30 mg kg(-1) after 9 (P<0.001), 17 (P<0.01) or 27 (P<0.001) days of treatment. Replacement of pravastatin with YM-53601 caused a decrease in plasma non-HDL cholesterol by 53% (P<0.001) and in HMG-CoA reductase activity. 4 This animal model thus satisfactorily replicates the escape phenomenon observed in humans and may therefore be useful in evaluation of lipid-lowering agents, specifically comparison of HMG-CoA reductase inhibitors. Further, YM-53601 may be useful in the treatment of hypercholesterolemia without induction of the escape phenomenon. Because enzymes can increase reaction rates by enormous factors, typically producing only a single product in quantitative yield, they are the focus of active research.In my other articles, you can also check out more blogs about 141627-42-1.

A small library of N-benzyl indolequinuclidinone (IQD) analogs has been identified as a novel class of cannabinoid ligands. The affinity and selectivity of these IQDs for the two established cannabinoid receptor subtypes, CB1 and CB2, was evaluated. Compounds 8 (R = R-2 = H, R-1 = F) and 13 (R = COOCH3, R-1 = R-2 = H) exhibited high affinity for CB2 receptors with K-i values of 1.33 and 2.50 nM, respectively, and had lower affinities for the CBI receptor (K-i values of 9.23 and 85.7 nM, respectively). Compound 13 had the highest selectivity of all the compounds examined, and represents a potent cannabinoid ligand with 34-times greater selectivity for CB2R over CB1R. These findings are significant for future drug development, given recent reports demonstrating beneficial use of cannabinoid ligands in a wide variety of human disease states including drug abuse, depression, schizophrenia, inflammation, chronic pain, obesity, osteoporosis and cancer.
