Abstract

Abstract : Two new quassinoids, perforalactones D and E, from Harrisonia perforata, could promote the expression of lysosomal genes and induce lysosomal biogenesis. 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.
