title: Non-nucleoside reverse transcriptase inhibitors: perspectives on novel therapeutic compounds and strategies for the treatment of HIV infection.
abstract: At present, the nucleoside reverse transcriptase (RT) inhibitors and protease inhibitors (PI) have dominated the therapeutic options for the treatment of human immunodeficiency virus (HIV) infection. From the initial monotherapeutic strategies, to the widely accepted multi-drug cocktails of today, the use of these two classes of compounds has successfully prolonged patient survival following infection with HIV. The efficacy of the multi-drug cocktails has delayed the onset of disease and generated hope that long-term therapy might allow the natural immune response to HIV infection to control both virus replication and pathogenesis within the context of an intact immune system despite the continuing presence of virus in various reservoirs within the body and the inability of these therapies to completely eradicate virus. However, the use of antiretroviral compounds for prolonged periods of time has also resulted in the appearance of significant drug-induced toxicity and metabolic abnormalities, as well as drug-induced variations in disease progression. Thus, continued research and development to identify new and improved antiretroviral agents will be a critical requirement in the foreseeable future. This ongoing research and development should also consider the challenges of defining more effective use of existing therapeutic agents, including the non-nucleoside reverse transcriptase inhibitors (NNRTIs).
