The 41-residue sequence of recently identified ovine corticotropin-releasing factor (CRF) was assembled on a benzhydrylamine resin support. Deprotection and cleavage from the resin were accomplished by HF treatment. The crude peptide was purified by gel filtration and reverse-phase, medium pressure, followed by high-performance liquid chromatography (HPLC). In addition to the usual criteria, the homogeneity of the final material, obtained in 7% yield, was assessed by the isolation and examination of cyanogen bromide cleavage and tryptic digestion fragments by HPLC and amino acid analysis. The synthetic 41 amino acid CRF stimulated the release of corticotropin (ACTH) in three in vitro systems: isolated rat pituitary quarters, monolayer cultures of dispersed pituitary cells, and superfused pituitary cells on a column, the responses being related to the log-dose of CRF in the range of 0.05–125 ng/ml. The synthetic peptide also augmented in vivo release of ACTH in rats pretreated with chlorpromazine, morphine, and Nembutal, as assessed by the measurement of serum corticosterone. The data indicates chemical purity and high biological activity of synthetic material.
