2-Azetidinones: Synthesis and biological evaluation as potential anti-breast cancer agents.

A series of twenty-five 2-azitidinone (β-lactam) derivatives were synthesized and evaluated for anti-cancer properties against breast cancer, MCF-7 and MDA-MB-231. These β-lactam derivatives depicted significant cytotoxicity in cancer cell lines but not in normal human mammary epithelial cells, MEpiC. Interestingly, derivatives of 2-bromo ethyl acrylonitrile (19w) exhibited - potent anti-proliferative activity with IC, 5.
