analysis of synthetic analogues of curacin A revealed the lack of activity of traditional heterocyclic replacements of the thiazoline ring or cyclopropyl analogues of the core diene segment. The significance of the C(3)-C(4)-(Z)-alkene geometry was established, and a novel oxime analogue was designed that displays biological properties that are a close match of the natural product lead.

姜黄素A合成类似物的结构活性关系分析表明,核心二烯链段的噻唑啉环或环丙基类似物的传统杂环替代品缺乏活性。建立了C(3)-C(4)-(Z)-烯烃几何结构的重要性,并设计了一种新型肟类似物,该类似物显示的生物学特性与天然产物铅非常匹配。亲脂性低,结构简化的肟50在抑制培养的人类肿瘤细胞生长方面仅比天然产物稍弱,并且发现在抑制纯化微管蛋白的组装方面比curacin A更有效。因此,肟部分很可能充当(Z)-烯烃基团的新型生物等排体。
