对新生霉素的香豆素核心和苯甲酰胺侧链的结构修饰已成功将天然产物从选择性 DNA 促旋酶抑制剂转化为 Hsp90 C 端的有效抑制剂。然而,没有对 noviose 附属物进行构效关系研究,它代表了类似物制备中的限速合成子。因此,合成并评估了一系列糖模拟物和非糖衍生物,以鉴定表现出 Hsp90 抑制作用的简化化合物。对两种乳腺癌细胞系的评估表明,用简化的烷基胺替代立体化学复合物 noviose 增加了抗增殖活性,导致新生霉素类似物的 IC 50值在中纳摩尔范围内。

Novobiocin analogues are useful in methods of treating, inhibiting, and/or preventing cyst formation in autosomal dominant polycystic kidney disease (ADPKD) in a subject. The disclosure provides methods of treating ADPKD comprising administering a therapeutically effective amount of a coumarin-3-carboxamide novobiocin analogue. Accordingly, the method can include administering a novobiocin analogue in a therapeutically effective amount for reducing levels of mTOR pathway phosphoproteins P-mTOR, P-Akt and P-S6K, or combinations thereof. Further, the method can include administering a novobiocin analogue in a therapeutically effective amount for reducing levels of Hsp-90 client proteins CFTR, ErbB2, c-Raf and Cdk4, or combinations thereof.
