developmental space of C-terminal inhibitors is limited. It was hypothesized that the combination of two previously identified scaffolds into a single structure could provide a platform for which to probe the three-dimensional space within the Hsp90 C-terminal binding pocket. The resulting chimeric compounds displayed anti-proliferative activity at low micromolar concentrations and manifested inhibitory activity
Hsp90 C末端的抑制是治疗癌症的一种有吸引力的治疗范例,但是C末端
抑制剂的发展空间有限。假设两个先前鉴定的支架组合成单个结构可以提供一个平台,供其探测Hsp90 C末端结合口袋中的三维空间。所得的嵌合化合物在低微摩尔浓度下显示出抗增殖活性,并在Hsp90依赖性再成熟试验中表现出抑制活性。最初的结构-活性关系表明,该新支架以不同于母体化合物的构象结合Hsp90,因此,为开发更有效的Hsp90 C-末端结合口袋
抑制剂提供了新的机会。
