Abstract

AbstractNew coumarin‐benzimidazole hybrids (3a–f) have been synthesized from 4‐formylcoumarins and a series of N‐sulphonation (4 a‐f) and N‐methylation (5 a‐f) compounds were obtained from compounds (3a–f). All the synthesized compounds have exhibited good antimicrobial activity. Docking studies provide valuable insights to potential binding modes of inhibitors. Anti cancer activity of compound 4 a and 4 c have shown excellent activity against HeLa cell line. Whereas compound 4 a and 4 d exhibited higher activity against HT 29 cell lines. We calculated the LC50, TGI and GI50 which show < 10 mg/mL. The synthesized compounds were characterized by IR, NMR, Mass spectral analysis and few of them by single X‐ray crystallography analysis.
