Sciadotenia toxifera

Sciadotenia toxifera Krukoff and A. C. Smith (Menispermaceae) was the source (134,135) of sciadenine (279), C37H4ON206, colorless needles (CHC13-... [Pg.74]

A novel type of bisbenzylisoquinoline alkaloid containing one fully aromatic isoquinoline system is sciadoline, from Sciadotenia toxifera Kruhoff and A. C. Smith (Menispermaceae), which has been shown to have the structure (54) by spectroscopic studies.65 It is related to cycleanine (43 R1 = R2 = Me) and 7-nor-cycleanine (43 R1 = H, R2 = Me). [Pg.98]

The only alkaloid of this group is sciadenine (127) which is solely a metabolite of Sciadotenia toxifera (Menispermaceae). Sciadenine (127) has the same substitution as sciadoline (128) and sciadoferine (217)[two other alkaloids of the same plant], except that sciadenine contains a fully reduced ring A, while ring A of the other two alkaloids is oxidized to different degrees. [Pg.243]

Sciadotenia toxifera Krukhoff and A. C. Smith has been shown to contain isochondodendrine and a new base sciadoferine (47), which is 1,2-dehydro-N-desmethylnorcycleanine... [Pg.93]
