Development of a new tachykinin antagonist.
The mouse urinary bladder possesses a tachykinin receptor which responds to kassinin and eledoisin, but not to some other tachykinins. The action of kassinin, but not that of eledoisin, was blocked in a surmountable manner by a new tachykinin antagonist, D-Pro4, Val8, D-Trp (SP).
