Development of heat shock protein 90 (Hsp90) C‐terminal inhibitors has emerged as an exciting strategy for the treatment of cancer. Previous efforts have focused on modifications to the natural products novobiocin and coumermycin. Moreover, variations in both the sugar and amide moieties have been extensively studied, whereas replacements for the coumarin core have received less attention. Herein,
热激蛋白90(Hsp90)C末端抑制剂的开发已成为治疗癌症的令人兴奋的策略。先前的努力集中在对天然产物新霉素和香豆霉素的修饰上。此外,已经广泛研究了糖和酰胺部分的变化,而香豆素核心的替代品受到的关注较少。本文中,合成了24个糖和酰胺部分之间具有不同距离和角度的核。对多种癌细胞系表现出良好的抗增殖活性和Hsp90抑制活性的化合物是那些糖和酰胺部分之间的间隔为7.7至12.1Å,且夹角为180°的化合物。
