生物活性 | H3B-6545 is an oral, selectiveestrogen receptorcovalent antagonist (SERCA) for the research of metastatic ER-positive, HER2-negative breastcancer[1][2]. | ||||||||||||||||
IC50& Target | Estrogen receptor[1] | ||||||||||||||||
体外研究 (In Vitro) | H3B-6545 is a highly selective small molecule that potently antagonizes wild-type and mutant ERα in biochemical and cell based assays. In vitro comparisons with standard of care and other experimental agents confirm increased cell potency of H3B-6545 under continuous as well as washout treatment conditions[1]. H3B-6545, a member of a novel class of ERα antagonists refer to as selective ER covalent antagonist (SERCA), which inactivates both wild-type and mutant ERα by targeting C530 and enforcing a unique antagonist conformation. H3B-6545 is a first-in-class selective ER covalent antagonist (SERCA). H3B-6545 inhibits ERαWTactivity and growth of ERαWT-positive breast cancer lines. H3B-6545 potently inhibits ERαWTactivity and suppresses proliferation of ERαWT-positive breast cancer lines. With GI50s of 0.3-0.4, 1.0, 0.5, 5.2, and 0.2 nM for MCF7, HCC1428, BT483, T47D and CAMA-1 cell lines[1]. | ||||||||||||||||
体内研究 (In Vivo) | In vivo, once daily oral dosing of H3B-6545 shows potent activity and superior efficacy to fulvestrant in the MCF-7 xenograft model with maximal antitumor activity at doses >10x below the maximum tolerated dose in mice. In addition, H3B-6545 shows superior antitumor activity to Tamoxifen and Fulvestrant in patient derived xenograft models of estrogen receptor positive breast cancer including models carrying ERα mutations in rat and monkeys, H3B-6545 is well tolerated across a broad dose range and at exposures that significantly exceed those required for efficacy in mouse xenograft models[1]. | ||||||||||||||||
