Preclinical profile of BI 224436, a novel HIV-1 non-catalytic-site integrase inhibitor.
BI 224436 is an HIV-1 integrase inhibitor with effective antiviral activity that acts through a mechanism that is distinct from that of integrase strand transfer inhibitors (INSTIs). This 3-quinolineacetic acid derivative series was identified using an enzymatic integrase long terminal repeat (LTR) DNA 3'-processing assay. A combination of medicinal chemistry, parallel synthesis, and structure-...
متن کاملDiscovery of a small-molecule HIV-1 integrase inhibitor-binding site.
Herein, we report the identification of a unique HIV-1 integrase (IN) inhibitor-binding site using photoaffinity labeling and mass spectrometric analysis. We chemically incorporated a photo-activatable benzophenone moiety into a series of coumarin-containing IN inhibitors. A representative of this series was covalently photo-crosslinked with the IN core domain and subjected to HPLC purification...
متن کاملIdentification of a nucleotide binding site in HIV-1 integrase.
HIV-1 integrase is essential for viral replication and can be inhibited by antiviral nucleotides. Photoaffinity labeling with the 3'-azido-3'-deoxythymidine (AZT) analog 3',5-diazido-2', 3'-dideoxyuridine 5'-monophosphate (5N3-AZTMP) and proteolytic mapping identified the amino acid 153-167 region of integrase as the site of photocrosslinking. Docking of 5N3-AZTMP revealed the possibility for s...
متن کاملIdentification of an inhibitor-binding site to HIV-1 integrase with affinity acetylation and mass spectrometry.
We report a methodology that combines affinity acetylation with MS analysis for accurate mapping of an inhibitor-binding site to a target protein. For this purpose, we used a known HIV-1 integrase inhibitor containing aryl di-O-acetyl groups (Acetylated-Inhibitor). In addition, we designed a control compound (Acetylated-Control) that also contained an aryl di-O-acetyl group but did not inhibit ...
متن کاملProgress in HIV-1 integrase inhibitors: A review of their chemical structure diversity
HIV-1 integrase (IN) enzyme, one of the three main enzymes of HIV-1, catalyzed the insertion of the viral DNA into the genome of host cells. Because of the lack of its homologue in human cells and its essential role in HIV-1 replication, IN inhibition represents an attractive therapeutic target for HIV-1 treatment. Since identification of IN as a promising therapeutic target, a major progress h...
