Abstract
This report describes the rational design, synthesis, and pharmacological properties of an amide-linked cyclic analogue of gonadotropin-releasing hormone (GnRH) namely Cyclo(4−9)[Lys4,d-Trp6,Glu9]GnRH. The conformationally restricted analogue is characterized by reduced flexibility of the peptide strand due to the introduction of a β-turn mimetic through 4,9 residue amide cyclization. The cyclic analogue was found to stimulate gonadotropin gene expression in the goldfish pituitary with similar potency compared to two native forms of GnRH. Simulation studies based on ROE connectivities in linear GnRH and potency of cyclic analogue supports the His2, Trp3, Tyr5 clustering considered important for triggering receptor activation.
