A second mechanism is the disruption of important interactions on the inside of the pocket. For example, Y181C and Y188L result in the loss of important aromatic rings involved in NNRTI binding. [20] [21] The third type of mutations result in changes in the overall conformation or the size of the NNRTI binding pocket. An example is G190E, which ...
The discovery of the TIBO compounds led to the definition of the NNRTI class in the late 1980s [2] when they were unexpectedly found to inhibit RT. This finding initiated researches on mechanism of action for these compounds. The HEPT compounds were described before the TIBO compounds and were originally believed to be NRTIs.
B: Mechanism of action of the nucleotide analogue reverse-transcriptase inhibitor, tenofovir Most standard HIV drug therapies revolve around inhibiting the reverse transcriptase enzyme (RT), an enzyme that is necessary to the HIV-1 virus and other retroviruses to complete their life cycle. [ 5 ]
Rilpivirine, sold under the brand names Edurant and Rekambys, is a medication, developed by Tibotec, used for the treatment of HIV/AIDS. [5] [6] It is a second-generation non-nucleoside reverse transcriptase inhibitor (NNRTI) with higher potency, longer half-life and reduced side-effect profile compared with older NNRTIs such as efavirenz.
Mechanism of action [ edit ] Etravirine is a second-generation non-nucleoside reverse transcriptase inhibitor (NNRTI), designed to be active against HIV with mutations that confer resistance to the two most commonly prescribed first-generation NNRTIs, mutation K103N for efavirenz and Y181C for nevirapine .

Emtricitabine (commonly called FTC, systematic name 2',3'-dideoxy-5-fluoro-3'-thiacytidine [2]), with trade name Emtriva (formerly Coviracil), is a nucleoside reverse-transcriptase inhibitor (NRTI) for the prevention and treatment of HIV infection in adults and children.
Nevirapine was the first NNRTI approved by the U.S. Food and Drug Administration (FDA). It was approved June 21, 1996 for adults and September 11, 1998, for children. It was approved June 21, 1996 for adults and September 11, 1998, for children.
It is a non-nucleoside reverse transcriptase inhibitor (NNRTI) and works by blocking the function of reverse transcriptase. [1] Efavirenz was approved for medical use in the United States in 1998, [1] and in the European Union in 1999. [4] It is on the World Health Organization's List of Essential Medicines. [6]
