摘要: The CD4 binding site on HIV-1 gp120 has been validated as a drug target to prevent entry cells. Previously, we identified two small molecule inhibitors consisting of 2,2,6,6-tetramethylpiperidine ring linked by an oxalamide p-halide-substituted phenyl group, which this site, specifically, cavity termed "Phe43 cavity". Here use synthetic chemistry, functional assessment, and structure-based analysis explore variants each region these for improved antiviral properties. Alterations the group linker indicated that regions were close optimal in original lead compounds. Design series compounds, where tetramethylpiperidine was replaced with new scaffolds, led activity. These scaffolds provide insight into surface chemistry at entrance offer additional opportunities optimize further potential-next-generation therapeutics microbicides against HIV-1.
