Description

Physalaemin: An oligopeptide isolated from the skin of Physalaemus fuscumaculatus, a South American frog. It is a typical kinin, resembling SUBSTANCE P in structure and action and has been proposed as a sialagogue, antihypertensive, and vasodilator.

Research Excerpts

Overview

Physalaemin (Mr = 1284) is a potent undecapeptide from the skin of South American frogs. Physalaemin is a powerful stimulant of fluid secretion by both glands.

Dosage Studied

Dose-response curves showed that in the unoperated glands maximal secretory responses were obtained to an intravenous dose of 5-10 micrograms/kg. The amount of saliva secreted from the submaxillary gland was twice that from the parotid gland, and that physalaemin was more potent than substance P.

ExcerptRelevanceReference
" The order of potency, the maximal effect and the slope of the dose-response curve were examined with six tachykinins - substance P (SP), physalaemin, phyllomedusin, uperolein, eledoisin, kassinin - and several substance P fragments - SP-(2-11), SP-(3-11), SP-(4-11) and SP-(6-11)."( Interaction of tachykinins with an adrenergic receptor in the rat urinary bladder.
