Hemokinin 1 is a tachykinin peptide neurokinin-1 (NK1) receptor agonist.1,2,3,4,5 It induces migration of A375 and B16/F10 melanoma cells when used at a concentration of 1 µM, an effect that can be reversed by the NK1 receptor antagonist L-732,138 .1 Hemokinin 1 (0.001-0.1 µM) promotes the proliferation, migration, and tube formation of human umbilical vein endothelial cells (HUVECs).2 It induces the production of prostaglandin E2 in human colon mucosal and muscle explants.3 Intracerebroventricular administration of hemokinin 1 increases the latency to withdrawal in the tail-flick test in mice in a dose-dependent manner.4 It decreases mean arterial pressure (MAP) and heart rate in anesthetized rats when administered at doses ranging from 1 to 30 nmol/kg.5
