inhibitors of dihydropteroatesynthase from Escherichia coli. A number of 6-(alkylamino)-5-nitrosoisocytosines have in vitro potency equivalent with or superior to that of therapeutically effective sulfonamide inhibitors of the synthase. The sulfonamide drugs are known to compete for the p-aminobenzoic acid binding site of the synthase, and kinetic analysis of inhibition of the synthase by 6-(methyl

Several simple 8-substituted 9-alkyl- and 7,8-disubstituted 9-alkylguanine derivatives were synthesized as potentialantiviral agents. These were tested for antiviral protection against a lethal Semliki Forest virus (SFV) infection in mice, and their antiviral properties were evaluated from a structure-activity standpoint. In this model system, 9-alkylguanines with the alkyl chain consisting of four
