Method: Among the protease inhibitor resistance mutations, the I50V, I54M, and I84V were associated with resistance to darunavir.
Method: In this study, HIV-2 resistance mutations were identified using the list generated by the 'Collaborative HIV and Anti-HIV Drug Resistance Network', leading to the following mutations in reverse transcriptase - K65R, D67G/N, N69S/T, K70N/R, L74V, V111I, Y115F, M184I/V, Q151M, S215A/C/F/L/Y,
Tenofovir-based regimens associated with less drug resistance in HIV-1-infected Nigerians failing first-line antiretroviral therapy.
Result: Three patients had selected IAS PI major mutations (I50V, N83D, I84V and L90M).
Antiviral resistance and correlates of virologic failure in the first cohort of HIV-infected children gaining access to structured antiretroviral therapy in Lima, Peru: a cross-sectional analysis.
Method: The OLA was conducted according to the NIH protocol for mutations at HIV-1B protease positions D30N, I50V, V82A, V82S, V82T, I84V, N88D, and L90M as well as reverse transcriptase positions K103N, Y181C, K65R, T215F, T215Y, M184V, and Q151M.

Introduction: I50V also has a significant effect in destabilizing the PR dimer.
Introduction: In order to study the molecular basis for the potency of inhibitor 1 against drug resistant viral strains, crystal structures of inhibitor 1 complexes with PR mutants bearing single substitutions of R8Q, D30N, I50V, I54M and V82A (PRR8Q, PRD30N, PRI50V, PRI54M and PRV82A) were analyzed.
Introduction: Indeed, PR with I50V mutation exhibits significantly reduced inhibition b
"Description of the L76V resistance protease mutation in HIV-1 B and ""non-B"" subtypes."
Method: In our study, samples with at least one of the major PI RAM of the IAS-USA list as follows: D30N, V32I, M46I/L, I47A/V, G48V, I50L/V, I54L/M, Q58E, T74P, L76V, V82A/F/L/T/S, N83D, I84V, N88S, L90M were considered as PI-resistant issued from PI-experienced patients.
Structural and thermodynamic basis of amprenavir/darunavir and atazanavir resistance in HIV-1 protease with mutations at residue 50.
Abstract: The I50V substitution is often associated with amprenavir (APV) and darunavir (DRV) resistance, while the I50L substitution is observed in patients failing atazanavir (ATV) therapy.
Abstract: Thus, the varied inhibitor susceptibilities of I50V/L protease variants are largely a direct consequence of the interdependent changes in protease inhibitor interactions.
Abstract: To explain how APV, DRV, and ATV susceptibility are influenced by mutations at residue 50 in HIV-1 protease, structural and binding thermodynamics studies were carried out on I50V/L-substituted protease variants in the compensatory mutation A71V background.

Abstract: The concordance rates between the RFMP and direct sequencing assays for the examined codons were 97% (K65R), 97% (T69Ins/D), 97% (L74VI), 97% (K103N), 96% (V106AM), 97% (Q151M), 97% (Y181C), 97% (M184VI) and 94% (T215YF) in the reverse transcriptase coding region, and 100% (D30N), 100% (M46I), 100% (G48V), 100% (I50V), 100% (I54LS), 99% (V82A), 99% (I84V) and 100% (L90M) in th

Abstract: For the bound complex PR(I50V)-KNI-10075, an increased polar solvation free energy also contributes to the drug resistance.
Abstract: Our calculations indicate that the mutation I50V causes drug resistance against both inhibitors.
