Perforalactones D and E, two new C-20 quassinoids with potential activity to induce lysosomal biogenesis from the twigs of Harrisonia perforata (Blanco) Merr.

Abstract

Two new quassinoids (1 and 2) were isolated from the twigs of Harrisonia perforata (Blanco) Merr. Perforalactone E (2) possesses an uncommon hexacyclic 1α,12α:5α,13α-dicyclo-9βH-picrasane skeleton. Its structure was determined based on spectroscopic data and X-ray crystallography. Compounds 1 and 2 could significantly induce lysosomal biogenesis through transcriptional activation of lysosomal genes.
