Synthesis of new coumarin derivatives and evaluation of their anti-cancer activity

A fragment-based approach has been applied to derive 2-(7-hydroxy-2-oxo-2H-chromen-4- yl)acetic acid 1 into 4 new coumarin derivatives 2a-d through amide bonds. The compounds were screened for their anticancer activity using MTT assay on MCF-7 and HepG2 cell lines.
