Abstract
Abstract The current study describes synthesis of diindolylmethane (DIM) derivatives based-thiadiazole as a new class of urease inhibitors. Diindolylmethane is natural product alkaloid reported to use in medicinal chemistry extensively. Diindolylmethane- based-thiadiazole analogs ( 1–18 ) were synthesized and characterized by various spectroscopic techniques 1 HNMR, 13 C-NMR, EI-MS and evaluated for urease (jack bean urease) inhibitory potential. All compounds showed excellent to moderate inhibitory potential having IC 50 value within the range of 0.50 ± 0.01 to 33.20 ± 1.20 µ M compared with the standard thiourea (21.60 ± 0.70 µ M). Compound 8 (IC 50 = 0.50 ± 0.01 µ M) was the most potent inhibitor amongst all derivatives. Structure-activity relationships have been established for all compounds. The key binding interactions of most active compounds with enzyme were confirmed through molecular docking studies.
