Structure-Activity Relationship and Biological Investigation of a REV-ERBα-Selective Agonist SR-29065 (34) for Autoimmune Disorders.
Journal of medicinal chemistry(2023)
Abstract
Autoimmune diseases affect 50 million Americans, predominantly women, and are thought to be one of the top 10 leading causes of death among women in age groups up to 65 years. A central role for TH17 cells has been highlighted by genome-wide association studies (GWAS) linking genes preferentially expressed in TH17 cells to several human autoimmune diseases. We and others have reported that the nuclear receptors REV-ERBα and β are cell-intrinsic repressors of TH17 cell development and pathogenicity and might therefore be therapeutic targets for intervention. Herein, we describe detailed SAR studies of a novel REV-ERBα-selective scaffold. Metabolic stability of the ligands was optimized allowing for in vivo interrogation of the receptor in a mouse model of multiple sclerosis (EAE) with a ligand (34). Reduction in frequency and number of T-cells in the CNS as well as key REV-ERB target genes is a measure of target engagement in vivo.
