Description:

Tuberostemonine has antitussive activity, acts in part as an open-channel blocker at the crayfish neuromuscular junction; it also exhibits relatively higher intestinal permeabilities.

Oral absorption and antitussive activity of tuberostemonine alkaloids from the roots of Stemona tuberosa.   

The intestinal absorption of four stereoisomers of Tuberostemonine-type alkaloids, neoTuberostemonine (1), Tuberostemonine (2), Tuberostemonine H (3), and Tuberostemonine J (4), isolated from the antitussive Chinese medicinal herb Radix Stemonae, and the IN VIVO antitussive activity of alkaloids 1, 2 and 3 were investigated in the current study. 

METHODS AND RESULTS:

All three alkaloids exhibited dose-dependent inhibitory effects on citric acid-induced cough in guinea pigs after intraperitoneal administration. Alkaloid 2 had the same potency via both oral and intraperitoneal dosing, 1 exhibited significantly lower oral activity than that following intraperitoneal application, while 3 did not show oral activity. 

CONCLUSIONS:

Alkaloid 4 demonstrated a moderate permeability in Caco-2 monolayer cells while alkaloids 1, 2 and 3 exhibited relatively higher intestinal permeabilities, indicating that all four alkaloids tested had reasonable oral absorption.
