HIV-1 integrase is an essential enzyme for the replication cycle, and currently, inhibitors are in first line of treatment many guidelines. Despite discovery new inhibitors, including a class molecules with different mechanisms action, resistance still relevant problem, adding options to therapeutic arsenal fight viral Sisyphean task. Because difficulty cost vitro screenings, machine learning-d...
BACKGROUND Optimal regimen choice of antiretroviral therapy is essential to achieve long-term clinical success. Integrase inhibitors have swiftly been adopted as part of current antiretroviral regimens. The purpose of this study was to review the evidence for integrase inhibitor use in clinical settings. METHODS MEDLINE and Web-of-Science were screened from April 2006 until November 2012, as ...
Some new diazo incorporated coumarin compounds were designed and synthesized to evaluate their anti-HIV activity. Overall, compounds were active against HIV at 100 μM. Additionally, no cytotoxic effect was observed at this concentration. The compound with 4-chlorobenzyl group indicated the best anti-HIV activity (52%). Docking studies using the later crystallographic data available for PFV inte...
HIV-1 integrase binds site-specifically to the ends of the viral cDNA. We used two HIV-1 integrase-DNA cross-linking assays to probe the binding sites of integrase inhibitors from different chemical families and with different strand transfer selectivities. The disulfide assay probes cross-linking between the integrase residue 148 and the 5'-terminal cytosine of the viral cDNA, and the Schiff b...

Understanding the HIV integrase protein and mechanisms of resistance to HIV integrase inhibitors is complicated by the lack of a full length HIV integrase crystal structure. Moreover, a lentiviral integrase structure with co-crystallised DNA has not been described. For these reasons, we have developed a structural method that utilizes free software to create quaternary HIV integrase homology mo...
Integrase is actively studied as an antiviral target, but many inhibitors selected from biochemical screens fail to inhibit human immunodeficiency virus (HIV) replication or primarily affect off-site targets. Here we develop and validate a replication-competent, simian virus 40-HIV integrase mutant chimera as a novel tool to classify the mechanism of action of potential integrase inhibitors. Wh...
We have identified dihydroxythiophenes (DHT) as a novel series of human immunodeficiency virus type 1 (HIV-1) integrase inhibitors with broad antiviral activities against different HIV isolates in vitro. DHT were discovered in a biochemical integrase high-throughput screen searching for inhibitors of the strand transfer reaction of HIV-1 integrase. DHT are selective inhibitors of integrase that...
Here, we describe an HIV-infected patient with pretreatment resistance to raltegravir, nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors and protease inhibitors, and the ultimate ability to achieve viral suppression. Pretreatment integrase resistance testing is not routinely performed because transmitted integrase mutations conferring resistance to ral...
