Delavirdine susceptibilities and associated reverse transcriptase mutations in human immunodeficiency virus type 1 isolates from patients in a phase I/II trial of delavirdine monotherapy (ACTG 260).

چکیده
The development of human immunodeficiency virus type 1 resistance to delavirdine (DLV) was studied in subjects receiving DLV monotherapy. Phenotypic resistance developed in 28 of 30 subjects within 8 weeks. K103N and Y181C, which confer nonnucleoside reverse transcriptase inhibitor (NNRTI) cross-resistance, were the predominant reverse transcriptase mutations. P236L, which confers DLV resistance but hypersensitivity to other NNRTIs, developed in <10% of isolates.

Amino acid substitutions at position 190 of human immunodeficiency virus type 1 reverse transcriptase increase susceptibility to delavirdine and impair virus replication.
Suboptimal treatment of human immunodeficiency virus type 1 (HIV-1) infection with nonnucleoside reverse transcriptase inhibitors (NNRTI) often results in the rapid selection of drug-resistant virus. Several amino acid substitutions at position 190 of reverse transcriptase (RT) have been associated with reduced susceptibility to the NNRTI, especially nevirapine (NVP) and efavirenz (EFV). In the...

Delavirdine mesylate (U-90152T) is a highly specific nonnucleoside reverse transcriptase inhibitor currently under development for the treatment of AIDS. The excretion, disposition, and metabolism of delavirdine were investigated in Sprague-Dawley rats after oral administration of [14C]delavirdine mesylate at single doses ranging from 10 to 250 mg/kg and multiple doses ranging from 20 to 250 mg...
متن کاملGenetic divergence of human immunodeficiency virus type 1 Ethiopian clade C reverse transcriptase (RT) and rapid development of resistance against nonnucleoside inhibitors of RT.
We sequenced and phylogenetically analyzed the reverse transcriptase (RT) region of five human immunodeficiency virus type 1 isolates from treatment-naive Ethiopian émigrés to Israel. Heteroduplex mobility assays were performed to confirm the clade C status of env genomic regions. The RT sequences showed that the strains clustered phylogenetically with clade C viruses, and a KVEQ-specific motif...
متن کاملAntiretroviral resistance and genetic diversity of human immunodeficiency virus type 1 isolates from the Federal District, Central Brazil.
In the context of universal access to antiretroviral therapy, the surveillance of human immunodeficiency virus type 1 (HIV-1) genetic diversity and resistance becomes pivotal. In this work our purpose was to describe the genetic variability; prevalence of drug-resistance mutations; and genotypic resistance profiles in HIV-1 infected individuals under antiretroviral treatment, from the Federal D...

Limited information is available on the activity of antiretroviral drugs against human immunodeficiency virus type 2 (HIV-2) and simian immunodeficiency virus (SIV) strains to guide their use in treatment or prophylaxis. We evaluated the antiviral activity of 16 approved drugs and one experimental drug, AMD3100, against two wild-type HIV-2 (ROD and EHO) isolates, two strains of SIV (mac251 and ...
