Description and Uses
The roots of Sternona japonica contain this complex alkaloid which forms colourless crystals from MeOH containing solvent of crystallization. The base is dextrorotatory with [α]D + 147.8° and the ultraviolet spectrum shows a broad absorption maximum at 305 m/J.. The picrolonate has been prepared as yellow needles, m.p. 237°C. The structure given above is based upon X-ray crystallo_x0002_graphic analysis of the MeOH solvate and on the already established configuration of Stemonine (q.v.).
Protostemonine is an alkaloid which provided protective effects of protostemonine in LPS/GalN-induced acute liver failure.
