title: Abacavir prodrugs: microwave-assisted synthesis and their evaluation of anti-HIV activities.
abstract: The synthesis of a new series of abacavir prodrugs involving N2-substitution with various substituted benzaldehyde and ketone derivatives is described. The in vitro anti-HIV activities indicated that compound (3-(2-(4-methylaminobenzylideneamino)-6-(cyclopropylamino)-9H-purin-9-yl)cyclopentyl)methanol (3) was found to be most potent compound with EC50 of 0.05 microM and CC50 of >100 microM with selectivity index of >2000. Compound 3 was found to be 32 times more potent than the parent drug (EC50 of 1.6 microM). At pH 7.4, 37 degrees C, the hydrolytic t1/2 ranged between 120 and 240 min.
