Infection with human immunodeficiency virus type 1 (HIV-1),the retrovirus that causes the acquired immunodeficiency syndrome(AIDS), is one of the leading causes of death worldwide. Allcurrently available antiretroviral agents inhibit essentialHIV-1 enzymes either the reverse transcriptase or theprotease (Figure 1). Recent advances have markedly improvedthe outcome for many patients who receive these classes of antiretroviraldrugs. However, the success of current therapy is limited bythe emergence of drug-resistant viruses, the necessity of sustainedadherence to complex regimens, and the potential for toxic effects.Novel classes of safe and effective agents with . . .
