Background:
ACTH (1-16) is a peptide fragment of adrenocorticotropic hormone , a peptide hormone found in the brain that is involved in the biological stress response.1 It binds to melanocortin receptors (MCRs; Kis = 0.267, 19, 698, and 2,600 nM for MC1R, MC3R, MC4R, and MC5R, respectively).2 ACTH (1-16) (160 μg/kg, i.v.) increases mean arterial blood pressure (MAP) following bleeding-induced hypotension in a rat model of hemorrhagic shock 15-30 minutes after administration.3 It increases grooming behavior and the incidence of stretching and yawning syndrome (SYS) in rats when administered intraventricularly at 0.05 or 2 μg.4
