H3B-6545 hydrochloride

产品介绍

H3B-6545 hydrochloride 是一种有效的，具有口服活性的选择性雌激素受体共价拮抗剂 (SERCA)。H3B-6545 hydrochloride 可用于研究转移性 ER 阳性，HER2 阴性乳腺癌。

生物活性

H3B-6545 hydrochloride is an oral, selective estrogen receptor covalent antagonist (SERCA) for the research of metastatic ER-positive, HER2-negative breast cancer.

体外研究

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. 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 ERα^WT activity and growth of ERα^WT -positive breast cancer lines. H3B-6545 potently inhibits ERα^WT activity and suppresses proliferation of ERα^WT -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.

体内研究

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.
