Resistance mechanism of human immunodeficiency virus type-1 protease to inhibitors: A molecular dynamic approach
Human immunodeficiency virus type 1 (HIV-1) protease inhibitors comprise an important class of drugs used in HIV treatments. However, mutations of protease genes accelerated by low fidelity of reverse transcriptase yield drug resistant mutants of reduced affinities for the inhibitors. This problem is considered to be a serious barrier against HIV treatment for the foreseeable future. In this st...

متن کاملMaraviroc (Celsentri) for multidrug-resistant human immunodeficiency virus (HIV)-1.
(1) Maraviroc belongs to a new class of antiretroviral drugs designed to block entry of HIV-1 into CD4+ T-cells via the CCR5 coreceptor. It is indicated for combination therapy in treatment-experienced adults infected with CCR5-tropic HIV-1 that is resistant to multiple antiretroviral agents. (2) Results from two randomized controlled trials (RCTs) indicate that in treatment experienced patient...
متن کاملFitness landscape of human immunodeficiency virus type 1 protease quasispecies.
Here we show, at a high resolution (1%), the human immunodeficiency virus type 1 (HIV-1) protease gene quasispecies landscape from three infected naïve individuals. A huge range of genetic configurations was found (67%, 71%, and 80% of the nucleotide clones from the three individuals, respectively, were different), and these configurations created a dense net that linked different parts of the ...
متن کاملPharmacodynamics of human immunodeficiency virus type 1 protease inhibitors.
Many factors are involved in the success or failure of antiretroviral therapy. Recent data suggest that there are significant differences in drug absorption and disposition for the protease inhibitor class of antiretroviral drugs, and relationships between plasma concentrations and their antiviral effect have been described. Consequently, the issue of whether therapeutic drug monitoring should ...
