摘要: A series of twenty-five 2-azitidinone (β-lactam) derivatives were synthesized and evaluated for anti-cancer properties against breast cancer, MCF-7 MDA-MB-231. These β-lactam depicted significant cytotoxicity in cancer cell lines but not normal human mammary epithelial cells, MEpiC. Interestingly, 2-bromo ethyl acrylonitrile (19w) exhibited - potent anti-proliferative activity with IC50, 5.79 ± 0.01 μM 6.86 ± 0.009 μM In addition, an increased expression pro-apoptotic genes (p53, Bax, Bid) as well decreased mRNA cyclins D1, E Cdk 2, 6 along cycle arrest at G1 phase was observed. 19w treatment has shown higher percentage Annexin-positive cells indicating induction apoptosis. Further, docking studies confirmed interaction between ATP-binding catalytic site AKT1. Mechanistically, dose-dependent decrease phosphorylation AKT GSK-3β kinase activity. conclusion, derivative is a potential anti-breast therapeutic candidate targeting survival pathway (AKT/GSK3β).
