    Product Description

    ACTH (1-17) is a peptide fragment of adrenocorticotropic hormone (ACTH; Item No. 24257), a peptide hormone found in the brain that is involved in the biological stress response.1 It binds to melanocortin receptors (MCRs; Kis = 0.23, 14, 419, and 4,240 nM for MC1R, MC3R, MC4R, and MC5R, respectively).2 It is an agonist at MC1R, increasing adenylate cyclase activity with an EC50 value of 3.02 nM in HEK293 cells expressing MC1R.3 ACTH (1-17) (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.4 It induces melanogenesis in a biphasic manner (EC50s = 0.0001 and 0.08 nM) and differentiation of melanocytes when used at concentrations ranging from 0.01 to 1,000 nM.3,5
