Pterodon pubescens

The fruit oil of the leguminous tree Pterodon pubescens contains geranylgeraniol (3) and its terminal epoxide (98). This terminal epoxide is highly lethal to the cercariae of Schistosoma mansoni, the causative agent of schistosomiasis (Gilbert, 1977). Other unsaturated diterpenes such as dehy-droabietic acid, agathic acid, and copalic acid prevent cercar-ial penetration. [Pg.420]

Cassane and Miscellaneous Tricyclic Diterpenoids.—A group of furanoid diterpenoids, related to the caesalpins, has been isolated from Pterodon emargina-and P. pubescens. They include compounds (39—42). Some further diterpene alkaloids of the cassaic acid class have been isolated from Erythro-phleum ivorense. [Pg.171]
