examined in several series of N6-substituted 6-aminopyrimidines. The presence of alkyl groups as large as n-butyl in the 3-position of 6-(5-indanylamino)uracil had no effect on inhibitor-enzyme binding. Substituents in the 4-position of a series of 2-amino-6-(benzylamino)pyrimidines had complex effects: alkoxy and phenoxy derivatives were less active than the parent 4-oxo (isocytosine) compound, but alkylphenoxy

As part of a series of studies to discover new HIV reverse-transcriptase inhibitors, various novel 6α- and 6β-naphthylthio 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio) thymine (HEPT) derivatives were synthesized, and in vitro anti-HIV-1 activity was evaluated. The results revealed that most of 6α-naphthylthio HEPT derivatives (7a—w) showed good activity [for 7e, IC50 value of 0.048 μM and selectivity index (SI) value of 735; for 7h, IC50 value of 0.057 μM and SI value of 579; for 7k, IC50 value of 0.063 μM and SI value of 565], 6β-naphthylthio HEPT derivatives (8a—f) showed low activity, but the introduction of α nitro group to the C-1 position of the 6β-naphthyl ring in the 6β-naphthylthio series (11a—c) resulted in a dramatic increase in anti-HIV-1 activity.
