Targeting the protein-protein interaction (PPI) between nuclear factor erythroid 2-related factor 2 (Nrf2) and Kelch-like ECH-associated protein 1 (Keap1) is a potential therapeutic strategy to control diseases involving oxidative stress. Here, six classes of known small-mol. Keap1-Nrf2 PPI inhibitors were dissected into 77 fragments in a fragment-based deconstruction reconstruction (FBDR) study and tested in four orthogonal assays. This gave 17 fragment hits of which six were shown by X-ray crystallog. to bind in the Keap1 Kelch binding pocket. Two hits were merged into pyrazole I with a 220-380-fold stronger affinity (Ki = 16μM) relative to the parent fragments. Systematic optimization resulted in several novel analogs with Ki values of 0.04-0.5μM, binding modes determined by X-ray crystallog., and enhanced microsomal stability. This demonstrates how FBDR can be used to find new fragment hits, elucidate important ligand-protein interactions, and identify new potent inhibitors of the Keap1-Nrf2 PPI.
