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.

An expeditious, eco‐friendly, and efficacious protocol was achieved for the preparation of bis‐imidazoles and bis‐1,3‐thiazines from the reaction of tetracyanoethylene with dialdehydes or bis‐thiosemicarbazones, respectively. Merely mixing and sonicating the starting materials furnishes the desirable products in considerable yields. This reaction smoothly proceeded and presented many merits, over conventional
