(1R,2R,3S,3aR,8bS)-6-[[(2S,3R,6R)-6-[(1R)-1,2-Dihydroxyethyl]-3-methoxy-1,4-dioxan-2-yl]oxy]-2,3,3a,8b-tetrahydro-1,8b-dihydroxy-8-methoxy-3a-(4-methoxyphenyl)-3-phenyl-1H-cyclopenta[b]benzofuran-2-carboxylic acid methyl ester

ChEBI: An organic heterotricyclic compound that consists of a 2,3,3a,8b-tetrahydro-H-benzo[b]cyclopenta[d]furan framework substituted by hydroxy groups at positions C-1 and C-8b, a methoxycarbonyl group at C-2, a phen l group at C-3, a 4-methoxyphenyl group at C-3a, a methoxy group at C-8 and a 1,4-dioxan-2-yloxy group at position C-6 which in turn is substituted by a methoxy group at position 3 and a 1,2-dihydroxyethyl group at position 6. Isolated from Aglaia si vestris, it exhibits antineoplastic activity.

It is a natural flavogline compound from the group of cyclopenta[b]benzofurans,extracted from the fruits of Aglaila sylvestre, which shows anticancer activityagainst lung and breast cancers (Shoeb 2006). The plant extract is reported to bepotent against P-388 cells in in vivo experiments. In the hollow fiber in vivo assay,it shows cytotoxicity in a dose-dependent way. It works by altering the cell signal pathways that related to the cell survival as well as angiogenesis and exerts itseffects by inhibiting the translation of mRNA preferentially associated withmalignancy (Balunas and Kinghorn 2005; Cencic et al. 2009).
