Ac-[Nle4,D-Phe7]-α-MSH (4-10)-NH2 is a melanotropin, a melanocyte-stimulating hormone. Ac-[Nle4,D-Phe7]-α-MSH (4-10)-NH2 stimulates tyrosinase and exhibits thermoregulatory effect in rats model.
Ac-[Nle4,D-Phe7]-α-MSH (4-10)-NH2 (0.1 pM-1 μM; 48 h) stimulates tyrosinase activity in a dose-dependent manner in Cloudman S91 mouse melanoma cells[1].
Ac-[Nle4,D-Phe7]-α-MSH (4-10)-NH2 (0-50 pM; i.c.v.; single dose) exerts thermoregulatory effect in rats model[2].
