(-)-象牙(洪达木)酮宁是一种血管扩张药，也可以作为大脑的新陈代谢刺激剂。该化合物可以保护暴露于氰化钾中毒的小鼠大脑。研究表明(-)-象牙(洪达木)酮宁增加了乙酰胆碱对M2和M4受体的亲和力，并增加了卡巴胆碱，对苯二酚，呋喃丁醚，甲基呋喃丁酯，戊硫基TZTP，毛果芸香碱，氧代莫瑞莫林和氧代莫雷莫林的亲和力- M在M2受体上。研究还表明，(-)-象牙(洪达木)酮宁具有抗缺氧作用。 (-)-Eburnamonine is a vasodilator that also acts as a cerebral metabolic stimulant. The compound can protect the cerebral of mice exposed to potassium cyanide intoxication. Studies show that (-)-Eburnamonine increases the affinity of acetylcholine on the M2 and M4 receptors, as well as augment the affinity of carbachol , bethanechol, furmethide, methylfurmethide, pentylthio-TZTP, pilocarpine, oxotremorine and oxotremorine-M on the M2 receptors. Research also shows that (-)-Eburnamonine has antihypoxic effects.
