New aporphine alkaloids from guatteria foliosa.
Four new alkaloids were obtained from Guatteria foliosa, namely, the noraporphines (-)-3-methoxyputerine [1] and (+)-norguattevaline [2], the more highly oxidized (+)-3-methoxyguattescidine [3], and the oxoaporphine 3-methoxyoxoputerine [4]. Among several other known alkaloids also found in this same plant, (-)-3-hydroxynornuciferine, (-)-isoguattouregidine, and argentinine exhibited significant activity against Trypanosoma cruzi.
