Abstract

Synthetic C peptides, corresponding to the C helix of the HIV type 1 (HIV-1) gp41 envelope protein, are potent inhibitors of HIV-1 membrane fusion. One such peptide is in clinical trials. The crystal structure of the gp41 core, in its proposed fusion-active conformation, is a trimer of helical hairpins in which three C helices pack against a central coiled coil. Each C helix shows especially prominent contacts with one of three symmetry-related, hydrophobic cavities on the surface of the coiled coil. We show that the inhibitory activity of the C peptide C34 depends on its ability to bind to this coiled-coil cavity. Moreover, examining a series of C34 peptide variants with modified cavity-binding residues, we find a linear relationship between the logarithm of the inhibitory potency and the stability of the corresponding helical-hairpin complexes. Our results provide strong evidence that this coiled-coil cavity is a good drug target and clarify the mechanism of C peptide inhibition. They also suggest simple, quantitative assays for the identification and evaluation of analogous inhibitors of HIV-1 entry.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
