  Discovery and Modification of in Vivo Active Nrf2 Activators with 1,2,4-Oxadiazole Core: Hits Identification and Structure–Activity Relationship Study

  摘要：

  Induction of phase II antioxidant enzymes by activation of Nrf2/ARE pathway has been recognized as a promising strategy for the regulation of oxidative stress-related diseases. Herein we report our effort on the discovery and optimization of Nrf2 activators with 1,2,4-oxadiazole core. Screening of an in-house collection containing 7500 compounds by ARE-luciferase reporter assay revealed a moderate Nrf2 activator, 1. Aimed at obtaining more derivatives efficiently, molecular similarity search by the combination of 2D fingerprint-based and 3D shape-based search was applied to virtually screening the Chemdiv collection. Three derivatives with the same core were identified to have better inductivity of Nrf2 than 1 The best hit 4 was selected as starting point for structurally optimization, leading to a much more potent derivative 32. It in vitro upregulated gene and protein level of Nrf2 as well as its downstream markers such as NQO1, GCLM, and HO-1. It remarkably suppressed inflammation in the in vivo LPS-challenged mouse model. Our results provide a new chemotype as Nrf2-ARE activators which deserve further optimization with the aim to obtain active anti-inflammatory agents through Nrf2-ARE pathway.
