  Epothilone D and its 9-Methyl analogues: Combinatorial syntheses, conformation, and biological activities

  摘要：

  Epothilone D (Epo D) and its 9-Methyl conformational analogues were synthesized through a highly efficient combinatorial approach. The fragment E was synthesized in 11 total steps with 6 longest linear steps, and each aldehyde B was prepared via a 3-step sequence. Starting from the common precursor E and a suitable aldehydes B, each target molecule were obtained in only 4 steps. The 9-(S)-epo D and 9-(R)-epo D demonstrated significant difference in inhibition activities against cancer cell lines and in conformational analysis. (C) 2013 Elsevier Masson SAS.

Biological evaluation of these analogues revealed a number of exceptionally potent epothilone B analogues, demonstrating the potency enhancing effects of the fluorine residues and the aziridinyl moiety within the structure of the epothilone molecule and providing new and useful structure-activity relationships within this class of compounds.

  尽管在埃坡霉素领域进行了先前的研究，但该化合物家族中只有一个成员ixabepilone批准用于临床。有机合成和药物化学的最新进展使埃博霉素铅类似物进一步优化，旨在提高其效力和其他药理特性，这是对发现和开发新的抗癌药物（包括抗体-药物缀合物作为潜在的靶向癌症治疗方法）的追求的一部分。本文中，我们报告了一系列新型Epothilone B类似物的设计，合成和生物学评估，这些类似物配备了新颖的结构基序，包括含氟残基，12,13-二氟环丙基部分，单和二甲基化大内酯和1-酮大环系统，以及两个N-取代的ixabepilone类似物，其中的12 取代13-环氧化物和大内酰胺NH部分，前者具有取代的氮丙啶部分，而后者具有NCO-烷基残基（酰亚胺或氨基甲酸酯）。这些类似物的生物学评估揭示了许多异常有效的埃坡霉素B类似物，证明了埃坡霉素分子结构内氟残基和氮丙啶基部分的效力增强作用，并在此类化合物中提供了新的有用的构效关系。

  Stereoselective total syntheses of two novel conformationally restrained epothilone analogues are described. Evans asymmetric alkylation, Brown allylation, and a diastereoselective aldol reaction served as the key steps in the stereoselective synthesis of one of the two key fragments of the convergent synthetic approach. Enzyme resolution was employed to obtain the second fragment as a single enantiomer
