YQ-0629 is a specific HIF-2α inhibitor, binds to HIF-2α PAS-B domain with Kd of 57.5 uM.YQ-0629 could inhibit the expression of HIF-2α with or without the presence of PTX (3 nM) in MCF7 MS culture, does not bind to HIF-1α or affect the expression of HIF-1α.YQ-0629 suppresses self-renewal capacity and synergizes with PTX to reverse the chemoresistance of MCF7 MS.YQ-0629 inhibits growth of BCSCs derived from breast cancer patients and synergistically increases anti-BCSCs activity of PTX in vivo.
