Abstract: The present study is related to a commercially practicable new synthetic process for production of teneligliptin hydrobromide hydrate (1), a dipeptidyl peptidase-4 (DPP-4) inhibitor. Key strategies in the new process include preparation and isolation of new intermediates such as a better reactive nosyl derivative (3c) of l-proline methyl ester (2), its stereoselective substituted intermediate (5) with 1-(3-methyl-1-phenyl-1H-pyrazol-5-yl)piperazine (4) through SN2-type nucleophilic substitution, and isolation of carboxylic acid derivative 6 by deesterification of intermediate 5. The reaction conditions for preparation of new intermediates, and the additionally used coupling reaction for amidation and deprotection of N-Boc were optimized with control of impurities to improve the quality of drug molecule 1 with good yield. The developed synthetic strategy offers significant advantages over existing synthetic approaches, avoiding use of expensive reagents, long time consumption, and laborious procedures involving isolation of intermediates. The developed process for drug molecule 1, achieving overall yield of 37?39% over six sequential chemical transformations, enables rapid delivery of multi-kilogram quantities of the desired active pharmaceutical ingredient (API), meeting stringent purity requirements.

We report a novel methodology for preparing enantiomerically pure beta-lactams, starting from nitriles in diastereomeric ratios up to 10:1. The power of the methodology was demonstrated by the efficient synthesis of the cholesterol absorption inhibitor SCH 48462.

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.name: (S)-4-Isopropylthiazolidine-2-thione, you can also check out more blogs about76186-04-4

Cysteamine (1) was reported many years ago to reversibly inhibit lentil seedling amine oxidase, through the formation of a complex with thioacetaldehyde, the turnover product of 1. Herein, cysteamine (1) and its analogs 2-(methylamino)ethanethiol (3) and 3-aminopropanethiol (6) were found to be reversible inhibitors of bovine plasma amine oxidase (BPAO), but 2-(methylthio)ethylamine (7) was determined to be a weak irreversible inhibitor of BPAO. Based on our results, indicating the necessity of a sulfhydryl-amine for reversible inactivation of BPAO, the failure of inhibited BPAO to recover activity after gel filtration, the first-order kinetics of activity recovery upon dialysis, and 2,4,6-trihydroxyphenylalanine quinine (TPQ) cofactor transformation which indicated from the results of phenylhydrazine titration and substrate protection, we propose a mechanism for the reversible inactivation of BPAO by 1 involving the formation of a cofactor adduct, thiazolidine, between BPAO and 1.

Some new beta-lactams bearing biologically important morpholine ring have been synthesized by acylation of amino beta-lactams in the presence of morpholine-4-carbonyl chloride. These novel beta-lactams were prepared under mild reaction conditions without any solvent in short reaction times. Their biological activities have been examined against microbial agents such as Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa) and fungi such as Candida albicans (C. albicans) and Candida glabrata (C. glabrata). They have been also tested against Plasmodium falciparum K14 resistant strain and showed moderate to good IC50 values.

Vascular endothelial growth factor receptors (VEGFR) are kinase based receptors reported as a promising target in anti tumour therapy. VGEFR inhibitors are being investigated which can have important contribution in anti-angiogenic therapy for treatment of cancer. In the present study, an attempt has been made to develop a site-specific QSAR model in order to explore the definite sites of substitution of a series of 4-thiazolidinone derivatives having reported antitumor activity against h460 cell lines. Each molecule of the series was divided into seven fragments for varying substituent at the positions R1, R2, R3, R4, R5, R6 and R7 of the parent nucleus. GQSAR was performed using MLR, PCR, PLS and KNN methods of variable selection. Amongst these methods, PCR has come out with promising result as compared to other methods. A comparative docking study was performed to explore the particular sites of interactions within the binding cavity of VGEFR protein. (PDB id: 1Y6A). The important substitutions contributing towards the biological activity by interpreting the developed GQSAR equation using virtual studies were found out which are as follows. position R1 should be substituted with groups with low electro negativity and higher atomic mass, oxygen count at R5 should be increased which would act as hydrogen bond acceptors and total polar surface area at R7 has to be decreased by making substitutions of non polar groups to promote hydrophobic interactions.

We live in a world with complex diseases such as cancer which cannot be cured with one-compound one-target based therapeutic paradigm. This could be due to the involvement of multiple pathogenic mechanisms. One-compound-various-targets stratagem has become a prevailing research topic in anti-cancer drug discovery. The simultaneous interruption of two or more targets has improved the therapeutic efficacy as compared to the specific targeted based therapy. In this review, six types of dual targeting agents along with some interesting strategies used for their design and synthesis are discussed. Their pharmacology with various types of the molecular interactions within their specific targets has also been described. This assemblage will reveal the recent trends and insights in front of the scientific community working in dual inhibitors and help them in designing the next generation of multi-targeted anti-cancer agents.

A series of thiazolidinone derivatives with various aromatic aldehyde substitution were synthesized and characterized by physical (TLC and M.P.) and spectral data (IR, NMR and MASS). They were evaluated for antimicrobial potential against Gram positive Staphylococcus aureus, Bacillus subtilis, gram-negative Escherichia coli, Pseudomonas aeuroginosa, Shigella and fungi Candida albicans and Aspergillus niger. The initial screening using zones of inhibition at 50 mul concentration revealed that they are moderately active against the tested strains.
