The alpha-MSH (alpha-melanocyte-stimulating hormone) agonist, Ac-[Nle4, D-Phe7]alpha-MSH4-11NH2 (hereafter called ND4-11 alpha-MSH), is at least 10-fold more potent than alpha-MSH as a stimulus of tyrosinase activity in F1 variant cells of B16 melanoma. The binding to these cells during an incubatio
