Syntheses of the positional isomers of N-aminopyrimidine bases (1- and 3-amino derivatives of uracil, thymine, and cytosine), 3-aminopyrimidine deoxyribonucleosides (3-amino derivatives of deoxyuridine, thymidine, deoxycytidine), and related compounds are reported. Physicochemical properties of these N-aminopyrimidines are described.

N-Aminated nucleoside complexes of cis-dichloroplatinum(II) were synthesized, and their antitumor activities against L1210 cells in mice and in vitro were studied. While the native nucleosides failed to show any antitumor activity, the complexes exhibited high antitumor activity and had no nephrotoxicity in mice. Studies on their mode of action in vitro indicated that the ligands played characteristic
