| Abstract: | Abstract A novel series of neplanocin analogues, 6′-(3-sn-phosphatidyl)neplanocin As bearing a variety of fatty acyl or alkyl residues in the glyceride moiety (2b-2h), were synthesized by means of phospholipase D-catalyzed transphosphatidylation. Among them, 2b, 2c, and 2e each exhibited significant antitumor effect against P388 leukemia in mice, which evidently surpassed that of parent compound neplanocin A. |
