It is a non-nucleoside reverse transcriptase inhibitor (NNRTI) and works by blocking the function of reverse transcriptase. [5] Nevirapine was approved for medical use in the United States in 1996. [5] It is on the World Health Organization's List of Essential Medicines. [7] It is available as a generic medication. [5]
HIV-1 RT does not have proof-reading activity. This, combined with selective pressure from the drug, leads to mutations in reverse transcriptase that make the virus less susceptible to NRTIs and NNRTIs. Aspartate residues 110, 185, and 186 in the reverse transcriptase polymerase domain are important in the binding and incorporation of nucleotides.
The most popular target in the field of antiretroviral drug development is the HIV-1 reverse transcriptase (RT) enzyme. [1] There are two classes of drugs that target the HIV-1 RT enzyme, nucleoside/nucleotide reverse-transcriptase inhibitors (NRTIs/NtRTIs) and non-nucleoside reverse-transcriptase inhibitors (NNRTIs). Drugs in these classes are ...

A reverse transcriptase (RT) is an enzyme used to convert RNA genome to DNA, a process termed reverse transcription.Reverse transcriptases are used by viruses such as HIV, COVID-19, and hepatitis B to replicate their genomes, by retrotransposon mobile genetic elements to proliferate within the host genome, and by eukaryotic cells to extend the telomeres at the ends of their linear chromosomes.
Nucleoside reverse-transcriptase inhibitors (NRTI) and nucleotide reverse-transcriptase inhibitors (NtRTI) are nucleoside and nucleotide analogues which inhibit reverse transcription. HIV is an RNA virus, so it can not be integrated into the DNA in the nucleus of the human cell unless it is first "reverse" transcribed into DNA.
The reverse transcriptase of HIV-1 has been the main foundation for the development of anti-HIV drugs. [5] The first nucleoside reverse-transcriptase inhibitor with in vitro anti-HIV activity was zidovudine. [6] Since zidovudine was approved in 1987, six nucleosides and one nucleotide reverse-transcriptase inhibitor (NRTI) have been approved by ...
