Alkaloids from bufonid toads (Melanophryniscus): Decahydroquinolines, pumiliotoxins and homopumlliotoxins, indolizidines, pyrrolizidines, and quinolizidines

Skins of bufonid toads of the genus Melanophryniscus contain several classes of alkaloids: decahydroquinolines, pumiliotoxins, allopumiliotoxins, homopumiliotoxins, both 3,5- and 5,8-disubstituted indolizidines, 3,5-disubstituted pyrrolidines, and a 1,4-disubstituted quinolizidine. Tricyclic alkaloi...

Sumario:Skins of bufonid toads of the genus Melanophryniscus contain several classes of alkaloids: decahydroquinolines, pumiliotoxins, allopumiliotoxins, homopumiliotoxins, both 3,5- and 5,8-disubstituted indolizidines, 3,5-disubstituted pyrrolidines, and a 1,4-disubstituted quinolizidine. Tricyclic alkaloids, including precoccinelline [193A] and alkaloid 236, an oxime methyl ether, are present in one population of Melanophryniscus stelzneri. © 1993, American Chemical Society.
