  Novel 5β-hydroxyspirostan-6-ones ecdysteroid antagonists: Synthesis and biological testing

  摘要：

  Eight new 5 beta-hydroxy-spirostan-6-ones bearing hydroxy and amino functions in the A ring, i.e., 3 beta-OH, 3 alpha-OH, 2 beta,3 beta-OH, 2 alpha,3 beta-OH, 3 beta-NH2, 2 alpha-NH2-3 beta-OH, 2 beta-NH2-3 beta-OH, and 2 beta-OH-3 beta-NH2, were efficiently synthesized, and their antiecdysteroid activities were evaluated on the metamorphosis bioassay of mosquito Aedes aegypti. To our knowledge, these new steroids represent the first 5 beta-hydroxy-spirostanes which have been tested for antiecdysteroid activity in mosquitoes. The higher antagonistic effect was found for compounds bearing the 3 beta-hydroxy and 2 beta,3 beta-dihydroxy functionality which show promise as environmental friendly insecticides.

  great efficiency for the ligation of two bulky building blocks (e.g., chacotriose derivatives and spirostanes bearing axial azides), which enabled the rapid creation of a small library of triazole-based analogs for cytotoxicity evaluation. A molecular modeling study was performed to understand the conformational and electronic differences between a natural saponin and its triazole-based analogs.

  描述了螺环皂苷的新型类似物，其中糖苷键已被三唑键取代。为此，基于Cu I的直接寡糖-类固醇结合方法催化的叠氮化物-炔烃1,3-偶极环加成反应得以实现，从而导致皂苷类似物的各种组合具有三糖部分，人工连接和类固醇骨架功能化的变化。这种“点击”过程证明了用于连接两个笨重的构建基块（例如带有轴向叠氮化物的查三糖衍生物和螺环烷烃）的高效连接，从而能够快速创建一个小的三唑类类似物文库来进行细胞毒性评估。进行了分子建模研究，以了解天然皂苷及其基于三唑的类似物之间的构象和电子差异。
