生物活性
描述 Denudatin B, a natural product isolated and purified from the herbs of Kadsura coccinea, inhibits the aggregation and ATP release of washed rabbit platelets caused by platelet-activating factor (PAF) in a concentration-dependent manner, has nonspecific antiplatelet action at high concentration by inhibiting phosphoinositides breakdown induced by collagen and thrombin, relaxes vascular smooth muscle by inhibiting the Ca2+ influx through voltage-gated and receptor-operated Ca2+ channels and its effect to increase cGMP may enhance the vasorelaxation and shows potent 2, 2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging activity.
