2'-Deoxy-2'-methylenecytidine (DMDC, 1) and its 5-fluoro congener (5-F-DMDC, 2), potent antitumor nucleosides developed by us, were efficiently converted to their 5'-phosphatidyl derivatives bearing palmitoyl residues (3 and 4, respectively) as novel antitumor phospholipids by phospholipase 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 clearly superior to that of DMDC. Compound 3 was a good substrate for phospholipase A2 from bovine pancreas as well as phospholipase D from Streptomyces, while it was slightly hydrolyzed by phospholipase C from Bacillus cereus.

The synthesis of nine enantiopure structured triacylglycerols (TAGs) of the AAB type is described, all possessing the (S)-absolute configuration. Six of them possess one saturated and two identical unsaturated fatty acyl chains, whereas the remaining three possess two identical saturated fatty acids along with one unsaturated fatty acid. The former group was synthesized by a five-step chemoenzymatic route involving a highly regioselective immobilized Candida antarctica lipase, starting from enantiopure (R)-solketal. The second group was prepared by a fully chemical five-step approach based on the same chiral precursor. Such enantiopure TAGs are strongly required as standards for the enantiospecific analysis of intact TAGs in fats and oils.
