Antitumor agents XXXVI: Structure elucidation of sesquiterpene lactones microhelenins-A, B, and C, microlenin acetate, and plenolin from Helenium microcephalum

The antitumor sesquiterpene lactones microhelenine-A, B, and C, microlenin acetate, and plenolin were isolated from Helenium microcephalum. The structures and stereochemistry of these lactones were determined by physical methods as well as by chemical transformations and correlations. Microlenin acetate appears to be the first novel dimeric sesquiterpene lactone demonstrated to have significant antileukemic activity.
