Design and synthesis of aminocoumarin derivatives as DPP-IV inhibitors and anticancer agents

Abstract

DPP-IV "a moonlighting protein" has immerged as promising pathway to control Type 2 diabetes as well as found to play key role in earlier stages of cancer. Here we have reported design, synthesis and applications of aminocoumarin derivatives as DPP-IV inhibitors. Compounds have been synthesized and studied for their DPP-IV inhibition activity. Three compounds have shown moderate inhibition at 100 µM concentration. All compounds were also screened for their anticancer activity against A549 (Lung cancer cell line), MCF-7 (Breast cancer cell line) using MTT assay. One of the compounds has shown very good anticancer activity with IC₅₀ value 24 ± 0.1 nM against A549 cell line.

Keywords: 3-Aminocoumarin derivatives; 7-Amino-4-methylcoumarin derivatives; Anticancer activity; DPP-IV inhibition.
