  Syntheses of brostallicin starting from distamycin A

  摘要：

  Two syntheses of brostallicin, a DNA minor groove binder now undergoing phase II studies, starting from distamycin A are described. One approach is based upon the selective hydrolysis via imide activation of the C-terminus amide. Besides employing traditional solution-phase synthesis, the convenient use of a polymer-supported reagent is also discussed. The other one is based upon the Curtius rearrangement of the C-terminus side chain of a convenient intermediate, easily prepared in two steps by straightforward functional group manipulation of distamycin A.

  Compounds which are &agr;-halogenoacryloyl distamycin derivatives of formula (I) wherein R 1 is a bromine or chlorine atom; R 2 is a distamycin or distamycin-like framework as set forth in the specification; or a pharmaceutically acceptable salt thereof; are cytotoxic agents particularly effective in the treatment of tumors over expressing GSH/GSTs system and which are poorly responsive or even resistant to conventional antitumor therapies.

  公式（I）中的α-卤代丙烯酰基二氨基链霉素衍生物，其中R1是溴或氯原子；R2是按规范所述的二氨基链霉素或类似二氨基链霉素框架；或其药学上可接受的盐；是细胞毒剂，特别是对于在GSH/GST系统过度表达且对传统抗肿瘤治疗反应不佳甚至耐药的肿瘤的治疗非常有效。
