2-dimethyl-2,3-dihydro-1,5-benzoxazepine (RS03) and RS12 displayed potent cytotoxicity in both benign (MCF-7) and metastatic (MDA-MB-231) breast cancer cells. These compounds were more selective for the MCF-7 cells with RS03 being the most potent compound (IC50 = 15 µM) of the series. Upon further investigation, it was found that RS03 and RS12 induced cell cycle arrest in the G2/M phase and display limited toxicity
