Background:
Neurokinin A is a peptide agonist of the neurokinin-2 (NK2) receptor. It potentiates electrically-induced contractions of isolated rat vas deferens and increases vasodilation in the rat hind paw. Neurokinin A (0.3-30 nmol/kg, i.v.) induces bronchoconstriction in guinea pigs in a dose-dependent manner (EC50 = 29 nM), an effect which can be reversed by the NK2 receptor antagonist MEN 10,207.
