Abstract
2'-Deoxy-2'-methylenecytidine (DMDC, 1) and its 5-fluoro congener (5-F -DMDC, 2), potent antitumor nucleosides developed by us, were efficien tly converted to their 5'-phosphatidyl derivatives bearing palmitoyl r esidues (3 and 4, respectively) as novel antitumor phospholipids by ph ospholipase D-catalyzed trans-phosphatidylation. These phospholipids 3 and 4, administered i.p., remarkably prolonged the life-span of mice which were i.p.-inoculated with M5076 sarcoma, and the effects were cl early superior to that of DMDC. Compound 3 was a good substrate for ph ospholipase A(2) from bovine pancreas as well as phospholipase D from Streptomyces, while it was slightly hydrolyzed by phospholipase C from Bacillus cereus.
