Amino Acid Sequence

H2N-(CH2)4-CO-Phe-Pro-NMe-Leu-Met-NH2

General description

Neurokinin (NK) receptors are acted upon by tachykinins or neurokinins namely, NKA and NKB. These are endogenous ligands. An exogenous agonist/ligand for NK1 is GR 64349 petpide.

Biochem/physiol Actions

GR 73632 interacts with neurokinin (NK1) receptor, which results in rhythmic tapping of hind-foot in gerbils. Administration of this peptide in the intra-ventral tegmental area (VTA) results in locomotor activity. It interacts with and activates NK1 receptors present on smooth muscle and interstitial cells of Cajal, resulting in elevated distention-induced peristalsis.

Intracerebroventricular (i.c.v.) administration of tachykinin NK(1) receptor agonists induces tapping of the hind legs in gerbils, so-called gerbil foot tapping, which is thought to reflect a fear-related response. The aim of the present study was to examine how ligands selective

Significant electrophysiological and biochemical findings suggest that receptor cross-talk occurs between serotonergic 5-HT(3)- and tachykininergic NK(1)-receptors in which co-activation of either receptor by ineffective doses of their corresponding agonists (serotonin (5-HT) or substance P (SP), respectively) potentiates the activity of

The pharmacological properties of the novel neurokinin-1 (NK(1)) receptor antagonist FK886, ([3,5-bis(trifluoromethyl)phenyl][(2R)-2-(3-hydroxy-4-methylbenzyl)-4-{2-[(2S)-2-(methoxymethyl)morpholin-4-yl]ethyl}piperazin-1-yl]methanone dihydrochloride), were studied. FK886 potently inhibited the binding of [(125)I]Bolton-Hunter-labeled substance P ([(125)I]BH-SP; 100 pM) to human NK(1) receptors expressed in Chinese hamster ovary (CHO) cells (IC(50)=0.70 nM).
