Nrf2 Activator II, AI-1 - CAS 75483-04-4 - Calbiochem

General description

A cell-permeable chloro-quinolinone compound that selectively and covalently modifies Kelch-like ECH-associated protein 1 (Keap1)-Cys¹⁵¹ and represses Keap1 function and reduces Nrf2 (Nuclear factor E2-related factor 2)-Keap1 interaction. Shown to stabilize Nrf2 by inhibiting the Keap1-driven ubiquitination of Nrf2 and thereby activating the Nrf2-ARE (antioxidant response element) pathway (EC₅₀ = 2.7 µM in neuroblastoma IMR-32 cells). Offers protection against H₂O₂ induced oxidative stress, but unlike tert-butylhydroquinone (Cat. No. 286888) AI-1 does not act as a free radical scavenger. Its anti-oxidant effects are mediated via Nrf2 induced antioxidant response. Does not affect mutant ARE where GC are substituted with AT within the core ARE sequence.
