Design, Synthesis and Biological Evaluation of Novel 4-Substituted Coumarin Derivatives as Antitumor Agents.

ABSTRACT: Herein, fifteen new compounds containing coumarin, 1,2,3-triazole and benzoyl- substituted arylamine moieties were designed, synthesized and tested in vitro for their anticancer activity. The results showed that all tested compounds had moderate antiproliferative activity against MDA-MB-231, a human breast cancer cell line, under both normoxic and hypoxic conditions. Furthermore, the 4-substituted coumarin linked with benzoyl 3,4-dimethoxyaniline through 1,2,3-triazole (compound 5e) displayed the most prominent antiproliferative activities with an IC₅₀ value of 0.03 μM, about 5000 times stronger than 4-hydroxycoumarin (IC₅₀ > 100 μM) and 20 times stronger than doxorubicin (IC₅₀ = 0.60 μM). Meanwhile, almost all compounds revealed general enhancement
