GSK 4112 is a synthetic ligand for REV-ERBα, a member of the nuclear receptor superfamily that functions as a receptor for the porphoryin heme. GSK 4112 mimics the action of heme acting as agonist and suppresses the expression of REV-ERBα target genes involved in gluconeogenesis.
GSK4112 is a rev-erbα, (orphan nuclear receptor NR1D1) agonist, the first agent able to reset the circadian clock in a phase-dependent manner. Rev-erbα impacts the precision of the circadian clock by repressing target gene activities with the help of a nuclear receptor co-repressor complex (NCoR) and HDAC3. GSK4112 competes with heme (rev-erb′s natural ligand) and enhances co-repressor complex recruitment and thus, repression of transcription. suggests that pharmacological modulation through Rev-erb may provide new routes to treat metabolic diseases, especially disorders of adipogenesis regulated by rev-erba.
