| Description | ACTH 4-11 acetate is an adrenocorticotropin hormone fragment and possesses the same amino acid sequence as α-melanocyte stimulating hormone (MSH) does. ACTH 4-11 acetate exhibits a weak MSH potency only at high doses (100 and 1000 nM). |
| In vitro | MSH能够促进小鼠表皮黑色素细胞在体内外的分化，而ACTH 4-11 acetate几乎失去了与黑色素皮质素受体1（MC1R）[1]结合的活性。 |
