title: Structure of a pineal gland-derived antigonadotropic decapeptide.
abstract: An antigonadotropic decapeptide was extracted from bovine pineal glands, purified by ultrafiltration and Sephadex G-25 gel-filtration chromatography and isolated by serial semi-preparative high performance liquid chromatography. Its primary structure was determined by automated amino acid and microsequence analyses. A synthetic analog of the decapeptide, prepared by solid state methods, was observed to reduce circulating levels of luteinizing hormone and prolactin after intra-atrial injection in male rats.
