SB-T-101141

SB-T-101141 is a novel taxane. SB-T-101141 effectively induces a noncanonical ferroptosis to overcome Paclitaxel resistance of breast cancer. SB-T-101141 facilitates the production of iron and ferrous ions and ROS. SB-T-101141 stably binds to KHSRP to inhibit the iron-dependent expression of CISD1 related to iron homeostasis. SB-T-101141 synergistically enhances the iron-dependent activation of JNK and PERK pathways via KHSRP. SB-T-101141 suppresses breast tumor growth in MCF-7 (PR) /MDA-MB-231 (PR) or KHSRP knock-down MCF-7 xenograft mice model[1].
