Studies on peptides. LXXV. Synthesis of the hexadecapeptide corresponding to the entire amino acid sequence of .BETA.-melanocyte-stimulating hormone from the dogfish (Squalus acanthias).

Abstract
In a conventional manner, the hexadecapeptide corresponding to the entire amino acid sequence of dogfish .beta.-MSH [melanocyte stimulating hormone] was synthesized using protecting groups removable HF. The synthetic peptide exhibited the in vitro MSH activity of 1.88 .times. 109 MSH [units]/g.
