Showdomycin analogs: synthesis and antitumor evaluation
摘要:
The synthesis of N-beta-D-ribofuranosyl derivatives of maleimide, 3-methylmaleimide, and 3-chloromaleimide was accomplished in three steps from ribosylamine. The synthetic ribosides can be considered N-nucleoside analogues of showdomycin, which is an antitumor antibiotic of the C-nucleoside type. Although the three analogues were cytotoxic to cultured L1210 cells, no in vivo antitumor activity was found with the murine P388 leukemia test system. Drug transport studies were done in an attempt to trace the biological fate of the analogues.
