Abuta grisebachii

Abuta grisebachii Triana and Planchon (Prance) is the sole ingredient of a curare used by the Sanama Indians of the Venezuela-Brazil border region. An extract of the stem wood afforded macolidine (193), along with the other newly reported alkaloids, macoline (Section II,C,58), 7-C>-demethylpeinamine (Section II,C,24), A-methyl-7-O-demethylpeinamine (Section II,C,65), and peinamine (Section II,C,92). [Pg.50]

Two related alkaloids, grisabine (53 R = Me) and grisabutine (53 R = H), have been isolated from Abuta grisebachii Triana et Planchon. Their structures were determined by splitting the diphenyl ether linkage with sodium-liquid ammonia ... [Pg.97]

Abuta grisebachii Triana and Planchon (Menispemiaceae)[240] Pachygone dasycarpa Kurz (Menispermaceae)(7]... [Pg.30]

There are only three alkaloids in this small subgroup, and all are derivatives of the monophenolic [C(12)], monosecondary [N(2)] alkaloid peinamine (71a) which has only been isolated from Abuta grisebachii (Menispermaceae). The other two alkaloids are 7-0-demethylpeinamine (60a) and N-methyl-7-O-demethylpeinamime (66b), both being metabolites of the same plant as above. In addition, the latter has been isolated from Pachygone dasycarpa (Menispermaceae). [Pg.217]
