Biochem/physiol Actions

Brain-penetrant alpha-melanocyte-stimulating hormone (α-MSH)-derived melanocortin receptors (MC1R, MC3R, MC4R) agonist with in vivo sexual arousal efficacy.
Bremelanotide (PT-141) is a brain-penetrant, alpha-melanocyte-stimulating hormone (α-MSH)-derived cyclic heptapeptide agonist toward melanocortin receptors, including MC1R, MC3R and MC4R (affinty = 10 nM by competitive binding against 0.2 nM NDP-α-MSH using human MC4R-expressing HEK-293). Bremelanotide induces cAMP accumulation in hMC4R-expressing HEK-293 cells and exhibits in vivo sexual arousal efficacy among both male (50 μg/kg intranasally or 50-500 pg/kg via lateral ventricle injection) and female rats (100-200 μg/kg sc or 800 μg/kg via lateral ventricle injection) by activating neurons in brain regions responsible for sexual function.

Hypothalamic neuropeptides centrally modulate sexual arousal. However, the role of neuropeptides in peripheral arousal has been ignored. Vascular and non-vascular smooth muscle relaxation in the vagina is important for female sexual arousal. To date, in vitro studies have focused on

PT-141, a synthetic peptide analogue of alpha-MSH, is an agonist at melanocortin receptors including the MC3R and MC4R, which are expressed primarily in the central nervous system. Administration of PT-141 to rats and nonhuman primates results in penile erections. Systemic
