Abstract
γ‐MSH, a third melanotropic sequence in the N‐terminal cryptic portion of the ACTH/β‐LPH precursor molecule pro‐opiocortin, was synthesized by the fragment condensation approach. The dodecapeptide H‐Tyr‐Val‐Met‐Gly‐His‐Phe‐Arg‐Trp‐Asp‐Arg‐Phe‐Gly‐OH was tested for melanocyte‐stimulating activity on the skin of the lizard Anolis Carolinensis and was found to possess only 2.5 × 10^−4^ of the activity of α‐MSH.
