Chiral polyoxometalate-based materials: From design syntheses to functional applications

Owing to the potential applications in catalysis, analytical chemistry, ion exchange, magnetism, biological chemistry and medicine, tremendous effort has been dedicated to exploring polyoxometalate (POM) chemistry. Chiral POM-based materials are particularly attractive due to the combination of the advantage of POMs with the importance of chirality. Nearly 100 chiral POM-based compounds were reported, which were mainly used as asymmetric catalysts, molecular recognition and nonlinear optical materials. In addition, the chirality within POM systems has attracted the attention of theoretical chemists and research was carried out to explore the origin of chirality by density functional theoretical methods. In this review, we summarize the developments of chiral POM-based materials, including their synthetic strategies, calculations on the origin of chirality and the relevant applications.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about Synthetic Route of 4971-56-6!, Safety of (R)-3-Aminoquinuclidine dihydrochloride

Primary open angle glaucoma: an overview on medical therapy

The purpose of this review is to discuss the topics relevant to the use of intraocular pressure-lowering strategies, which remains the first line in the management of glaucoma. Estimates of blindness from glaucoma and identification of risk factors remain of interest for all ophthalmologists. New functional tests offer promise for better detection and more accurate diagnosis of glaucoma. We finally discuss the impact of various glaucoma therapies, the principles of monotherapy and fixed combinations, which offer benefits of convenience, cost, and safety.

Influence of the acyl moiety on the hydrolysis of quinuclidinium esters catalyzed by butyrylcholinesterase

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 (Ka = 3.3.60 mumol 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. A reaction mechanism is the microscopic path by which reactants are transformed into products.

Novel serotonin type 3 receptor partial agonists for the potential treatment of irritable bowel syndrome

Serotonin type 3 (5-HT3) receptor partial agonists are being targeted as potential new drugs for the treatment of irritable bowel syndrome (IBS). Two new chemical series bearing indazole and indole cores have exhibited nanomolar binding affinity for the h5-HT3A receptor. A range of partial agonist activities in HEK cells heterologously expressing the h5-HT 3A receptor were measured for the indazole series. Excellent 5-HT3 receptor selectivity, favorable in vitro metabolic stability and CYP inhibition properties, and good oral in vivo potency in the murine von Bezold-Jarisch reflex model is exemplified thereby indicating the series to have potential utility as improved IBS agents.

Synthesis and 5-HT-3 receptor binding activity of 5-[125I]iodo-2,3-dimethoxy-N-(1-azabicyclo[2.2.2]oct-3-yl]benzamide and its 5-halogen-2-alkoxyl homologues

(S)-5-Iodo-2,3-dimethoxy-N-(1-azabicyclo[2.2.2]oct-3-yl)benzamide (MIZAC) was prepared from 5-iodo-2,3-dimethoxybenzoyl chloride and (S)-3-aminoquinuclidine. [125I]Iodode-stannylation of its corresponding 5-tri-n-butyltin derivative gave [125I]-MIZAC at 1800 Ci/mmol. Binding of [125I]-MIZAC in rat entorhinal cortex revealed a K(D) of 1.37 ¡À 0.21 nM. A series of racemic 2-O-alkyl derivatives of MIZAC were prepared and 5-HT-3 receptor affinities were determined by inhibition of [125I]-MIZAC binding. Optimal affinity for the receptor was obtained with small, electron-withdrawing substituents in the aromatic 5-position and with bulky substituents in the 3-position. [125I]-MIZAC is a selective radioligand useful for in vitro identification of the 5-HT-3 receptor.
