    摘要:
    生物活性聚酮化合物埃坡霉素的构象与活性关系已经确定。基于计算机的分子建模和高场核磁共振技术为埃坡霉素 1 和 2 提供了解决方案的选择。对于 C1-C8 聚丙酸酯区域,两个构象家族,即构象异构体 1 和 2,已被确定为在极性和非极性区域具有显着的群体。 -极性溶剂。在 C11-C15 区域,观察到额外的灵活性,并且已确定两个重要的局部构象,即构象异构体 3 和 4。已设计并合成了具有改变构象特征的埃坡霉素类似物。构象分析和生物测定结果相互关联,以加深对埃坡霉素类天然产物的生物活性构象的了解。构象-活性关系已被证明是结构-活性数据的重要补充。

    Rapid access to epothilone analogs via semisynthetic degradation and reconstruction of epothilone D
    摘要:
    A facile and efficient route to epothilone analogs has been developed from the natural product epothilone D (1). Degradation of 1 via an oxidative cleavage sequence provides acid intermediate 4 rapidly in six steps. From 4, a variety of epothilone analogs have been prepared utilizing ring-closing metathesis to reconstruct the trisubstituted-12,13-double bond. Using this approach, we report a number of epothilone analogs with varying C-15 aromatic side chains and C-14 allylic substitutions and their biological activities. (C) 2004 Elsevier Ltd.

  • Conformation−Activity Relationships in Polyketide Natural Products:  A New Perspective on the Rational Design of Epothilone Analogues
    作者:Richard E. Taylor、Yue Chen、Alicia Beatty、David C. Myles、Yiqing Zhou
    DOI:10.1021/ja028196l
    日期:2003.1.1
    The syntheses of C14-methyl analogues of epothilone B and D are described. Conformational analysis using computational methods, X-ray crystallography, and NMR studies showed that the stereochemistry at C14 has a pronounced effect on the conformation of the epoxide region. Biological assays indicated significant differences in their biological activity. Substitution which stabilized conformer I retained significant biological activity. In contrast, substitution which stabilized conformer II provided analogues with no measurable cytotoxicity. The conformation-activity relationships strongly support the importance of conformer I as the bioactive conformation of the epoxide region of epothilone. The approach presented here offers a new perspective on rational design of modified biologically active polyketides.
