Synthesis, Biological Evaluation, and Molecular Docking Studies of Novel Isatin-Thiazole Derivatives as ?-Glucosidase Inhibitors.


ABSTRACT: A series of novel isatin-thiazole derivatives were synthesized and screened for their in vitro ?-glucosidase inhibitory activity. These compounds displayed a varying degree of ?-glucosidase inhibitory activity with IC50 ranging from 5.36 ± 0.13 to 35.76 ± 0.31 ?m as compared to the standard drug acarbose (IC50 = 817.38 ± 6.27 ?m). Among the series, compound 6p bearing a hydroxyl group at the 4-position of the right phenyl and 2-fluorobenzyl substituent at the N1-positions of the 5-methylisatin displayed the highest inhibitory activity with an IC50 value of 5.36 ± 0.13 ?m. Molecular docking studies revealed the existence of hydrophobic interaction, CH-? interaction, arene-anion interaction, arene-cation interaction, and hydrogen bond between these compounds and ?-glucosidase enzyme.
