Drogas anti-VIH: passado, presente e perspectivas futuras Drugs anti-HIV: past, present and future perspectives

By Marcus Vinícius Nora de Souza and Mauro Vieira de Almeida


<abstract language="eng">Currently available anti-HIV drugs can be classified into three categories: nucleoside analogue reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs). In addition to the reverse transcriptase (RT) and protease reaction, various other events in the HIV replicative cycle can be considered as potential targets for chemotherapeutic intervention: (1) viral adsorption, through binding to the viral envelope glycoprotein gp120; (2) viral entry, through blockage of the viral coreceptors CXCR4 and CCR5; (3) virus-cell fusion, through binding to the viral envelope glycoprotein gp 41; (4) viral assembly and disassembly through NCp7 zinc finger-targeted agents; (5) proviral DNA integration, through integrase inhibitors and (6) viral mRNA transcription, through inhibitors of the transcription (transactivation) process. Also, various new NRTIs, NNRTIs and PIs have been developed, possessing different improved characteristics
