title: Synthesis and antiviral activity of C-5 substituted analogues of d4T bearing methylamino- or methyldiamino-linker arms.
abstract: A general strategy is reported for the preparation of C-5-methylamino- or methyldiamino-d4T analogues of "different sizes". Reactions of the 2',3'-didehydro-2',3'-dideoxy-C-5 hydroxymethyl precursor (7) with either polymethylene diamines (n = 6, 8, 10 and 12) or propargylamine proceed regioselectively via substitution reactions at the C-5 position of uracil. The compounds were evaluated for antiviral activity and cytotoxicity. No significant activity was observed for compounds 9, 11, and 13, but 10 and 12 exhibited a weak activity against HIV-1.
