Where Did Our Drugs Come From? New morphine comes from frogs Epibatidine The skin of the phantasmal 地棘蛙素 poison frog contains epibatidine 'Frog Man Amphibian skin has provided a wide range of biologically active alkaloids.During the past 30 years,>400 alkaloids of>20 structural classes have been detected by Daly.Total 800 Amphibian alkaloids reported. Epibatidine was discovered by John W.Daly in 1974.The structure of epibatidine was elucidated in 1992.About 28 structural classes of alkaloids are known in poison frogs
