Nevirapine resistance mutation at codon 181 of the HIV-1 reverse transcriptase confers stavudine resistance by increasing nucleotide substrate discrimination and phosphorolytic activity.

چکیده
Recombinant HIV-1 reverse transcriptase (RT) carrying non-nucleoside inhibitors (NNRTIs) resistance mutation at codon 181 showed reduced incorporation and high efficiency of phosphorolytic removal of stavudine, a nucleoside RT inhibitor. These results reveal a new mechanism for cross-resistance between different classes of HIV-1 RT inhibitors.

Drug resistance mutations in the nucleotide binding pocket of human immunodeficiency virus type 1 reverse transcriptase differentially affect the phosphorolysis-dependent primer unblocking activity in the presence of stavudine and zidovudine and its inhibition by efavirenz.
Human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) derivatives with D113E, Y115F, F116Y, Q151E/N, and M184V mutations were studied for their phosphorolysis-mediated resistance to the nucleoside RT inhibitors (NRTIs) zidovudine and stavudine and for their inhibition by the nonnucleoside analogs (NNRTIs) efavirenz and nevirapine. The results presented here indicate that these ...
متن کاملIncreased Risk of Q151M and K65R Mutations in Patients Failing Stavudine-Containing First-Line Antiretroviral Therapy in Cambodia
BACKGROUND Multi-nucleos(t)ide resistance (MNR) mutations including Q151M, K65R mutations, and insertion at codon 69 of HIV-1 reverse transcriptase coding region may confer resistance to all molecules of nucleos(t)ide reverse transcriptase inhibitors (NRTI). The presence of these mutations is an emerging problem compromising non-nucleoside reverse transcriptase inhibitors and protease inhibitor...
متن کاملMulti-nucleoside reverse transcriptase inhibitor resistant HIV type-1 in a patient from Sierra Leone failing stavudine, lamivudine and nevirapine.
We report a 33-year-old HIV type-1 (HIV-1)-infected male from Sierra Leone who harboured extensive drug resistance mutations to all nucleoside reverse transcriptase inhibitors (NRTIs) and non-NRTIs, including the multi-NRTI-resistance Q151M complex, K65R, M184I and Y181I, after using standard first-line generic fixed-dose stavudine, lamivudine and nevirapine (Triomune™) for 36 months. In the co...
متن کاملThe human immunodeficiency virus type 1 nonnucleoside reverse transcriptase inhibitor resistance mutation I132M confers hypersensitivity to nucleoside analogs.
We previously identified a rare mutation in human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT), I132M, which confers high-level resistance to the nonnucleoside RT inhibitors (NNRTIs) nevirapine and delavirdine. In this study, we have further characterized the role of this mutation in viral replication capacity and in resistance to other RT inhibitors. Surprisingly, our data ...
متن کاملInsertions and deletions in HIV-1 reverse transcriptase: consequences for drug resistance and viral fitness.
Human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) is an important target of drugs fighting HIV infection. The introduction of potent antiretroviral therapies based on the use of RT inhibitors and/or protease inhibitors has been an important achievement towards the control of AIDS. However, the development of drug resistance constitutes a major hurdle towards long-term effic...
