Peptide inhibitors of the Keap1–Nrf2 protein–protein interaction with improved binding and cellular activity

Abstract

Inhibitors of the Keap1-Nrf2 protein-protein interaction (PPI) have been proposed as potential anti-inflammatory and cancer chemopreventive agents. Such compounds have the potential to increase the intracellular concentrations of Nrf2 in a reversible manner and consequently increase the expression of a battery of gene products with antioxidant response elements (AREs) in their promoter region. In this manuscript we describe the development of peptide inhibitors with modified C- and N-termini and reduced overall charge. The activity of the compounds in inhibiting the PPI and in cellular assays of Nrf2 function are described. Compound 10 has potent activity (IC50 = 22 nM) in a cell-free fluorescence polarisation assay and induced the expression of Nrf2 dependent gene products in cells, suggesting that it has potential as a lead molecule for the development of peptidomimetic inhibitors.

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.
