Biological Activity
Description: Isorhyncophylline and rhyncophylline can directly inhibit the contractile responses induced by several agonists in small blood vessels of rat, they also can inhibit the hypertensive effect of angiotensin Ⅱ.
Targets: Potassium Channel
In vivo:
Acta Academiae Medicinae Zunyi, 1994 (1) :7-10.
Effects of rhyncophylline and isorhyncophylline on the contractile responses of rat isolated mesenteric arteries and tail artery[Reference: WebLink]

METHODS AND RESULTS:
In rat isolated mesenteric arteries and tail artery, rhyncopylline (Rhy)and Isorhyncophylline(Isorhy)inhibited the increased infusion pressure induced by high K+ (80 mmol/L) and noradrenaline(NA)in a concentration-dependent manner. The potency of both drugs were similar in mesenteric arteries, but in tail artery,the effect of Rhy on high K+ induced infusion pressure increase was weaker than that of Isorhy, and there was a similar trend in the contractile response induced by NA. Both drugs also inhibited the hypertensive effect of angiotensin Ⅱ.
CONCLUSIONS:
The results suggest that in small blood vessels of rat,Rhy and lsorhy can directly inhibit the contractile responses induced by several agonists, but in some arteries, the effect of Rhy may be weaker than that of Isorhy.
