  Synthesis and cytotoxicity of 4′-C- and 5′-C-substituted toyocamycins

  摘要：

  Toyocamycin and some analogues have shown potent antitumor activities; however, none of them could be used clinically primarily owing to their cytotoxicity to normal human cells. In order to overcome the weakness of these nucleoside analogues, substitution of a variety of modified sugars for the ribofuranose was explored in our laboratories with expectation that certain sugar-modified toyocamycin analogues may be selectively cytotoxic to cancer cells. In this article, we report synthesis and cytotoxicity of 4'-C- and T-C-substituted toyocamycins, which were prepared via the condensations of 4-C- and 5-C-substituted ribofuranose derivatives 11, 12, 13, 20, 21, and 26 with the silylated form of 4-amino-6-bromo-5-cyanopyrrolo[2,3-d]py (27) and subsequent debromination and debenzoylation. When compared to the parent toyocamycin, all these analogues showed much lower cytotoxicity to human prostate cancer cells (HTB-81), mouse melanoma cancer cells (B16) as well as normal human fibroblasts. Compound le showed a significant cytotoxicity to the prostate cancer cells and a moderate selectivity. The results suggested that sugar modifications, especially those that may affect phosphorylation of nucleosides, could alter cytotoxicity profile significantly. (C) 2000 Elsevier Science Ltd.
