制备方法与用途

生物活性

VER-49009 是一种强效的 HSP90 抑制剂，其 IC50 为 47 nM。

在 体外研究 中，VER-49009 抑制重组酵母 HSP90 蛋白的内源性 ATP 酶活性，IC50 值为 167 nM。该化合物对部分人肿瘤细胞系和非肿瘤细胞具有抗增殖活性。VER-49009 可诱导 HSP72 和 HSP27与其结合蛋白（C-RAF、B-RAF、生存素及 PRMT5）解离，从而导致细胞周期阻滞和凋亡。此外，该化合物能够抑制细胞增殖，并诱导肝细胞 CFSC 的 G2 期阻滞，提供了阻止肝纤维化的一个合理治疗策略。

  Novel, Potent Small-Molecule Inhibitors of the Molecular Chaperone Hsp90 Discovered through Structure-Based Design

  摘要：

  The crystal structure of a previously reported screening hit 1 (CCT018159) bound to the N terminal domain of molecular chaperone Hsp90 has been used to design 5-amide analogues. These exhibit enhanced potency against the target in binding and functional assays with accompanying appropriate cellular pharmaeodynamic changes. Compound 11 (VER-49009) compares favorably with the clinically evaluated 17-AAG.
