Abstact

The ectodomain of HIV-1 gp41 mediates the fusion of viral and host cellular membranes. The peptide-based drug Enfuvirtide(1) is precedent that antagonists of this fusion activity may act as anti HIV-agents. Here, NMR screening was used to discover non-peptide leads against this target and resulted in the discovery of a new benzamide 1 series. This series is non-peptide, low molecular weight, and analogs have activity in a cell fusion assay with EC50 values ranging 3-41microM. Structural work on the gp41/benzamide 1 complex was determined by NMR spectroscopy using a designed model peptide system that mimics an open pocket of the fusogenic form of the protein.
