Synthesis, in vitro evaluation and molecular docking studies of thiazole derivatives as new inhibitors of α-glucosidase
摘要:
A series of thiazole derivatives 1-21 were prepared, characterized by EI-MS and H-1 NMR and evaluated for alpha-glucosidase inhibitory potential. All twenty one derivatives showed good alpha-glucosidase inhibitory activity with IC50 value ranging between 18.23 +/- 0.03 and 424.41 +/- 0.94 mu M when compared with the standard acarbose (IC50, 38.25 +/- 0.12 mu M). Compound (8) (IC50, 18.23 +/- 0.03 mu M) and compound (7) (IC50 = 36.75 +/- 0.05 mu M) exhibited outstanding inhibitory potential much better than the standard acarbose (IC50, 38.25 +/- 0.12 mu M). All other analogs also showed good to moderate enzyme inhibition. Molecular docking studies were carried out in order to find the binding affinity of thiazole derivatives with enzyme. Studies showed these thiazole analogs as a new class of a-glucosidase inhibitors. (C) 2015 Elsevier Inc. All rights reserved.

Aryl thiosemicarbazones react rapidly in a facile procedure with dimethyl acetylene-dicarboxylate to give substituted (ylidene) hydrazono(4-oxothiazolidin-5-ylidene) acetates in high yields. The synthesised compounds were characterised by spectroscopic methods and the structures confirmed by single crystal X-ray crystallography. Several mechanistic options involving nucleophilic interaction are presented

A Series of Benzylidenes Linked to Hydrazine‐1‐carbothioamide as Tyrosinase Inhibitors: Synthesis, Biological Evaluation and Structure−Activity Relationship
and enzymatic browning of vegetables and fruits. In the present article, 12 small molecules of benzylidene-hydrazinecarbothioamide were designed, synthesized and evaluated for their anti-tyrosinase activities followed by molecular docking and pharmacophore-based screening. Among synthesized thiosemicarbazone derivatives, 3d is the strongest inhibitor of mushroom tyrosinase with IC 50 of 0.05 µM which
