Synthesis, in vitro evaluation and molecular docking studies of thiazole derivatives as new inhibitors of α-glucosidase.
2015
Abstract A series of thiazole derivatives 1 – 21 were prepared, characterized by EI-MS and 1 H NMR and evaluated for α-glucosidase inhibitory potential. All twenty one derivatives showed good α-glucosidase inhibitory activity with IC 50 value ranging between 18.23 ± 0.03 and 424.41 ± 0.94 μM when compared with the standard acarbose (IC 50 , 38.25 ± 0.12 μM). Compound ( 8 ) (IC 50 , 18.23 ± 0.03 μM) and compound ( 7 ) (IC 50 = 36.75 ± 0.05 μM) exhibited outstanding inhibitory potential much better than the standard acarbose (IC 50 , 38.25 ± 0.12 μM). 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 α-glucosidase inhibitors.
