Apoptosisinducer 18 is an effective apoptosis-inducing agent that exhibits significant cytotoxicity against the breast cancer cell line MCF-7 (IC50 = 0.559 μM). It induces apoptosis by binding to DNA and causing damage, as well as interacting with the active site of CDK-2, which disrupts kinase activity, thereby impeding cell cycle progression. This compound can be utilized in breast cancer research.
