ClinConnect Summary

Current antiviral therapies for HIV-1 are limited by a few choices, and the lack of sustained clinical benefit from the drugs. The mechanisms that account for the lack of prolonged inhibition of viral replication by these agents are not fully understood. The activity of RT inhibitors might be potentiated by inhibiting host cellular enzymes essential for efficient HIV reverse transcription. Based on this information, comparisons of the antiviral effects of ddI monotherapy and hydroxyurea plus ddI, with the cellular enzyme ribonucleotide reductase as a potential target, should be done.
