简介内容:S-72 acts as a microtubule polymerization inhibitor, effective in cell-free assays at concentrations of 1, 3, and 10 ?M. At nanomolar levels (IC50s = and nM, respectively), it diminishes the viability of both MCF-7 and paclitaxel-resistant MCF-7/T breast cancer cells. Moreover, at 50 nM, S-72 impedes migration, invasion, and wound healing in these cell lines. Additionally, at 100 nM, it arrests the cell cycle at the G2/M phase and induces apoptosis in MCF-7/T cells, while also inhibi
