Inhibitors of HIV-1 Reverse Transcriptase—Associated Ribonuclease H Activity
HIV-1 enzyme reverse transcriptase (RT) is a major target for antiviral drug development, with over half of current FDA-approved therapeutics against HIV infection targeting the DNA polymerase activity of this enzyme. HIV-1 RT is a multifunctional enzyme that has RNA and DNA dependent polymerase activity, along with ribonuclease H (RNase H) activity. The latter is responsible for degradation of...
متن کاملHIV-1 Ribonuclease H: Structure, Catalytic Mechanism and Inhibitors
Since the human immunodeficiency virus (HIV) was discovered as the etiological agent of acquired immunodeficiency syndrome (AIDS), it has encouraged much research into antiviral compounds. The reverse transcriptase (RT) of HIV has been a main target for antiviral drugs. However, all drugs developed so far inhibit the polymerase function of the enzyme, while none of the approved antiviral agents...
متن کاملIdentification of Alternative Binding Sites for Inhibitors of HIV-1 Ribonuclease H Through Comparative Analysis of Virtual Enrichment Studies
The ribonuclease H (RNase H) domain on the p66 monomer of HIV-1 reverse transcriptase enzyme has become a target for inhibition. The active site is one potential binding site, but other RNase H sites can accommodate inhibitors. Using a combination of experimental and computational studies, potential new binding sites and binding modes have been identified. Libraries of compounds were screened w...
متن کاملSelective inhibition of HIV-1 reverse transcriptase-associated ribonuclease H activity by hydroxylated tropolones
High-throughput screening of a National Cancer Institute library of pure natural products identified the hydroxylated tropolone derivatives beta-thujaplicinol (2,7-dihydroxy-4-1(methylethyl)-2,4,6-cycloheptatrien-1-one) and manicol (1,2,3,4-tetrahydro-5-7-dihydroxy-9-methyl-2-(1-methylethenyl)-6H-benzocyclohepten-6-one) as potent and selective inhibitors of the ribonuclease H (RNase H) activity...
متن کاملColorimetric detection of HIV-1 ribonuclease H activity by gold nanoparticles.
Scheme 1 . Illustration of colorimetric detection of HIV-1 RNase H activity using unmodifi ed gold nanoparticles. Acquired immune defi ciency syndrome (AIDS) is generally characterized by infection of human immunodefi ciency virus type 1 (HIV-1). Despite enormous efforts in developing antiretroviral drugs, coping with the drug resistance of HIV-1 remains a daunting task. [ 1 ] The ribonuclease ...
