Abstact

Pharmacological activation of NRF2 (nuclear factor erythroid 2-related factor 2) arises from blocking the interaction of NRF2 with its negative regulator, KEAP1 (Kelch-like ECH-associated protein 1). We previously reported an isoquinoline-based NRF2 activator, but this compound showed negative logD7.4 and a -2 charge at physiological pH, which may have limited its membrane permeability. In this work, we report potent, metabolically stable analogs that result from replacing a carboxymethyl group at the 4-position with a fluoroalkyl group.
