Abstract
Acquired immunodeficiency syndrome (AIDS) is one of the most frightening diseases worldwide. Extensive effort has been spent to discover therapeutic agents targeting the etiological agent of AIDS, human immunodeficiency virus type 1 (HIV-1). Currently, the FDA (Food and Drug Administration) has approved twenty two anti-AIDS drugs including nucleoside reverse transcriptase inhibitors (zidovudine, abacavir, lamivudine, stavudine, didadosine, zalcitabine, entricitabine and tenofovir), non-nucleoside reverse transcriptase inhibitors (nevirapine, efavirenz and delavirdine), protease inhibitors (saquinavir, ritonavir, lopinavir, indinavir, nelfinavir, amprenavir, tipranavir, fosamprenavir, darunavir and atazanavir) as well fusion inhibitors (enfurvitide). This last category represents a promising strategy, due to it prevents the entrance of virus HIV in the target cell, being an important weapon in the combat to the appearance of resistant virus to medicines used. Due to the importance of alternative strategies in the fight to virus HIV and the relevance of the natural products in the discovery of new drugs, the aim of this article is to highlights triterpenes antifusing as a promising category of anti-HIV agents.
