This invention relates to the use of pterosin compounds of formula I for treating diabetes including type I and type II. Also disclosed is the use of the pterosin compounds for treating obesity.
Abstract A new illudane-type sesquiterpene glycoside, named dennstoside A, was isolated fromDennstaedtiascabra and characterized as an analogue of ptaquiloside, the carcinogenic principle of Pteridium aquilinum, on the basis of spectral analyses and chemical conversion to pterosin A.
Chemical and toxicological studies on bracken fern, Pteridium aquilinum var. latiusculum. II. Structures of pterosins, sesquiterpenes having 1-indanone skeleton.
The structures of twenty-four sesquiterpenes isolated from the young fronds were disclosed by chemical and physical methods. The stereostructures were established as 1-22 by degradation and correlation reactions and physical data.
