INCB057643 是一种新型有效、选择性、口服生物可利用的 BET 抑制剂。

INCB057643 is a novel potent, selective, orally bioavailable BET inhibitor; shows more effectivity against androgen-dependent (VCaP and LNCaP) than androgen-independent (DU145 and PC3) cells with IC50 of <100 nM and >500 nM, respectively; significantly causes inhibition of tumor growth in mice bearing 22Rv1 tumor xenografts.Solid Tumors Phase 2 Clinical.

INCB-057643 is a novel, orally bioavailable BET inhibitor. INCB-057643 inhibits binding of BRD2/BRD3/BRD4 to an acetylated histone H4 peptide in the low nM range, and is selective against other bromodomain containing proteins. In vitro analyses show that INCB-057643 inhibits proliferation of human AML, DLBCL, and multiple myeloma cell lines, with a corresponding decrease in MYC protein levels. Cell cycle analyses indicate that G1 arrest and a concentration-dependent increase in apoptosis are seen within 48 hours of treatment with INCB-057643.

Production of several cytokines, including IL-6, IL-10 and MIP-1α, is repressed by INCB-057643 in human and mouse whole blood stimulated ex vivo with LPS. Oral administration of INCB-057643 results in significant anti-tumor efficacy in xenograft models of AML, myeloma, and DLBCL. Additionally, combining INCB-057643 with standard of care agents used for the treatment of DLBCL including rituximab and bendamustine results in enhanced anti-tumor efficacy relative to that achieved with single agent therapies at doses that are well tolerated.
