Potent and highly selective human immunodeficiency virus type 1 (HIV-1) inhibition by a series of alpha-anilinophenylacetamide derivatives targeted at HIV-1 reverse transcriptase.

In vitro evaluation of a large chemical library of pharmacologically acceptable prototype compounds in a high-capacity, cellular-based screening system has led to the discovery of another family of human immunodeficiency virus type 1 (HIV-1) inhibitors. Through optimization of a lead compound, several alpha-anilinophenylacetamide (alpha-APA) derivatives have been identified that inhibit the replication of several HIV-1 strains (IIIB/LAI, RF, NDK, MN, HE) in a variety of host cell types at concentrations that are 10,000- to 100,000-fold lower than their cytotoxic concentrations. The IC50 of the alpha-APA derivative R 89439 for HIV-1 cytopathicity in MT-4 cells was 13 nM. The median 90% inhibitory concentration (IC90) in a variety of host cells was 50-100 nM. Although these alpha-APA derivatives are active against a tetrahydroimidazo [4,5,1-jk][1,4]benzodiazepin-2(1H)-thione-(TIBO)-resistant HIV-1 strain, they do not inhibit replication of HIV-2 (strains ROD and EHO) or simian immunodeficiency virus (strains Mac251, mndGB1, and agm3). An HIV-1 strain containing the Tyr181-->Cys mutation in the reverse transcriptase region displayed reduced sensitivity. alpha-APA derivative R 89439 inhibited virion and recombinant reverse transcriptase of HIV-1 but did not inhibit that of HIV-2. Reverse transcriptase inhibition depended upon the template/primer used. The relatively uncomplicated synthesis of R 89439, its potent anti-HIV-1 activity, and its favorable pharmacokinetic profile make R 89439 a good candidate for clinical studies.[1]
