| + | Keap1 binds to the Nrf2 transcription factor to promote its degradation, resulting in the loss of gene products that protect against oxidative stress. While cell-active small molecules have been identified that modify cysteines in Keap1 and effect the Nrf2 dependent pathway, few act through a non-covalent mechanism. We have identified and characterized several small molecule compounds that specifically bind to the Keap1 Kelch-DC domain as measured by NMR, native mass spectrometry and X-ray crystallography. One compound upregulates Nrf2 response genes measured by a luciferase cell reporter assay. The non-covalent inhibition strategy presents a reasonable course of action to avoid toxic side-effects due to non-specific cysteine modification. | ||
