Abstract A series of novel benzosuberone bearing coumarin moieties 5a–c have been synthesized and their structures were determined by analytical and spectral (FT-IR, 1 H NMR, 13 C NMR, HRMS) studies. The newly synthesized compounds were evaluated for their cytotoxicity against four human cancer cell lines, A549 (Human alveolar adenocarcinoma cell line), HeLa (Human cervical cancer cell line), MDA-MB-231 (Human ...
