In previous studies GnRH-III, a variant of the hypothalamic neurohormone GnRH, was isolated from the brain of the sea lamprey and structurally characterized. GnRH-III is a hypothalamic neurohormone in both female and male sea lampreys. In the present

A photoreactive derivative of the highly potent gonadotropin releasing hormone (GnRH) agonist, D-Lys6-GnRH(1-9)-ethylamide, was prepared by selective modification of the epsilon-amino group with 2-nitro-4-azidophenyl sulfenyl chloride (2,4-NAPS C1).

The aim of our work was to screen peptidomimetic tyrosine kinase inhibitory libraries for antiproliferative and apoptotic or necrotic effect. We also wanted to distinguish between cytostatic and cytotoxic activities.4-Benzylaminoquinasolines can be p

Gonadotropin releasing hormone (GnRH) is a decapeptide regulating the gonadotropin release in organisms. Its analogues inhibit breast, endometrium and prostatic tumor cell proliferation in vitro. Some analogues were conjugated via the lysine side cha

We have found that guanidine acetate catalyses the transformation of a β-benzyl-aspartyl peptide (Boc-Asp-(OBzl)-Leu-Trp-OMe) to an aminosuccinyl peptide (Boc-Asu-Leu-Trp-OMe). The reaction was accompanied by partial epimerization. However, not even

We examined the desensitization and/or sensitization phenomenon in the pituitary GH responsiveness induced by continuous infusion and multiple pulses at different frequencies of a potent GH-RH analog [D-Ala2, Leu15, Nle27, GABA30-GH-RH(1–30)amide].
