Abstract
Recent research has indicated pivotal roles for neuropeptides and their cognate receptors in reproductive physiology. Kisspeptins are RF-amide neuropeptides that stimulate gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus. Neurokinin B (NKB) is a member of the tachykinin family of neuropeptides and positively regulates pulsatile GnRH secretion. These peptides are coexpressed in kisspeptin/NKB/Dyn (KNDy) neurons of the arcuate nucleus, where they contribute to the regulation of puberty onset and other reproductive functions. In this review, the design of peptide ligands for the kisspeptin (KISS1R) and neurokinin-3 (NK3R) receptors are described. © 2016 Wiley Periodicals, Inc. Biopolymers (Pept Sci) 106: 588-597, 2016.
