Anticancer agent 183

This potent small molecule anticancer agent (compound 4h) strongly inhibits MMP-9 activity (>75% at 100 μg/mL) and demonstrates high cytotoxicity against A549 lung cancer cells (IC50 <0.14 μM) by inducing apoptosis. It is a valuable research tool for studying MMP-9 function and apoptosis mechanisms in both in vitro and in vivo oncology models.
