Studies on peptides. CXXIV. Solution synthesis of the hentetracontapeptide amide corresponding to the entire amino acid sequence of human corticotropin releasing factor (hCRF).

Abstract
The hentetracontapeptide amide corresponding to the entire amino acid sequence of human corticotropin releasing factor (hCRF), deduced from the complementary DNA (cDNA) sequence analysis, was synthesized by assembling 9 peptide fragments in solution followed by deprotection with 1 M trifluoromethanesulfonic acid-thioanisole (molar ratio 1:1) in trifluoroacetic acid. The synthetic peptide significantly elevated the immunoreactive corticotropin level in rat plasma.
