Abstract

The HIV-1 gp41 envelope glycoprotein promotes fusion of the virus and cell membranes through the formation of a trimer-of-hairpins structure, in which the amino- and carboxyl-terminal regions of the gp41 ectodomain are brought together. Synthetic peptides derived from these two regions (called N and C peptides, respectively) inhibit HIV-1 entry. In contrast to C peptides, which inhibit in the nanomolar range, N peptides are weak inhibitors with IC 50 values in the micromolar range. To test the hypothesis that the weak inhibition of N peptides results from their tendency to aggregate, we have constructed chimeric variants of the N-peptide region of gp41 in which soluble trimeric coiled coils are fused to portions of the gp41 N peptide. These molecules, which present the N peptide in a trimeric coiled-coil conformation, are remarkably more potent inhibitors than the N peptides themselves and likely target the carboxyl-terminal region of the gp41 ectodomain. The best inhibitors described here inhibit HIV-1 entry at nanomolar concentrations.
