Reverse transcriptase inhibitors (RTIs) show promise as HIV microbicides, with tenofovir and dapivirine leading clinical trials. Challenges include drug resistance and accessibility for global HIV prevention.
Area of Science:
- Medicinal Chemistry
- Virology
- Pharmaceutical Sciences
Background:
- The CAPRISA 004 study highlighted the potential of antiretroviral microbicides for HIV prevention.
- Microbicides target specific enzymes in the HIV replication cycle, particularly reverse transcriptase.
Purpose of the Study:
- To review the potential of HIV-1 reverse transcriptase inhibitors (RTIs) as microbicides.
- To discuss current research on RTI microbicides, considering medicinal chemistry, virology, and pharmaceutical aspects.
Main Methods:
- Review of existing research on HIV-1 RTIs as microbicides.
- Focus on nucleotide RTI tenofovir and six classes of nonnucleoside RTIs.
- Analysis of clinical trial data and unresolved issues.
Main Results:
- Tenofovir and dapivirine are the most advanced RTI microbicides in clinical trials.
- Several classes of nonnucleoside RTIs (e.g., UC781, PETTs, DABOs, pyrimidinedione) are under investigation.
- Key challenges include the role of nonhuman primates in trials, drug resistance, combination strategies, and accessibility.
Conclusions:
- RTI microbicides represent a promising avenue for HIV prevention, but further research is crucial.
- Addressing drug resistance, optimizing combinations, and ensuring global accessibility are critical for successful implementation.

This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
