The nonatriacontapeptide corresponding to the newly revised amino acid sequence of bovine adrenocorticotropic hormone was synthesized by successive condensation of 3 peptide fragments ; Z(OMe)-(15-19)-OH, Z (OMe)-(11-14)-OH and Z-(1-10)-OH, with H-(20-39)-OBzl, a synthetic intermediate of bovine type corticotropin-like intermediate lobe peptide. The synthetic peptide exhibited the in vivo steroidogenetic activity of 93.8 IU/mg.
