YZ-35 is a STAT3 inhibitor with a Ki value of 0.38 µM. It binds directly to STAT3 with high affinity, having a dissociation constant (Kd) of 190 nM. YZ-35 effectively inhibits the dual phosphorylation of STAT3 at Tyr705 and Ser727 sites. It also suppresses colony formation, cell migration, and induces apoptosis in breast cancer cell lines. Additionally, YZ-35 selectively inhibits the self-renewal capability of breast cancer stem cells (BCSC) and reduces tumor growth in breast cancer stem cell xenograft models. YZ-35 is applicable for breast cancer research.
