  C-15 Thiazol-4-yl Analogues of (E)-9,10-Didehydroepothilone D:  Synthesis and Cytotoxicity

  摘要：

  [GRAPHICS]The syntheses and biological evaluation of six epothilone D analogues are reported. These side-chain variants of the (E)-9,10-didehydroepothilone scaffold contain C-15 thiazole appendages that are derived from bromomethyl ketone intermediates. Although each of these analogues is less cytotoxic than the parent (E)-9,10-didehydroepothilone D, three maintain IC50 values in the double-digit nanomolar range against both susceptible and resistant cell lines.

  Preparation of epothilone derivatives

  摘要：

  该发明涉及一种新型工艺，用于制备式I的环丙沙星衍生物，其中R1和R2各自独立地表示氢或保护基，R3为甲基或三氟甲基，这些衍生物在合成式IV的去氧环丙沙星衍生物的前体中有用，其中R3为甲基或三氟甲基。式IV的去氧环丙沙星具有抑制肿瘤细胞生长的作用，因此是新型抗癌药物的有前途的候选药物。

  The invention comprises a novel process for the preparation of an epothilone derivative of formula I: wherein R 1 and R 2 independently from each other represent hydrogen or protecting groups and R 3 is methyl or trifluoromethyl, which are useful precursors in the synthesis of the desoxyepothilone derivatives of the formula IV: wherein R 3 is methyl or trifluoromethyl. The desoxepothilones of formula IV inhibit the growth of tumor cells and are therefore promising candidates for novel anticancer agents.

  The invention relates to a novel process for the preparation of an epothilone derivative of the formula (I) wherein R1 and R2 are silyl protecting groups, that uses a sultam alcohol of the formula (IV) wherein R is hydrogen or lower alkyl and R1 is a silyl protecting group, as intermediate. The compound of formula (I) is useful for the preparation of desoxyepothilones that are promising candidates for novel anticancer agents.
