Abstract:

In this study, two new holostane-type glycosides were isolated from the ethanol extract of Apostichopus japonicus Selenka. Combined spectral data analysis with physical and chemical properties, they were identified as 3β-O-{2-O-[3-O-methyl-β-D- glucopyranosyl-(1→3)-β-D-xylopyranosyl-(1→4)-β-D-quinovopyranosyl]-4-O-[β-D-glucopyranosyl]-β-D-xylopyranosyl}-holosta-7(8),25(26)-dien-16-one(compound 1, named holotoxin E1) and 3β-O-{2-O-[3-O-methyl-β-D-glucopyranosyl-(1→3)- β-D-xylopyranosyl-(1→4)-β-D-glucopyranosyl]-4-O-[β-D-glucopyranosyl-(1→3)-β-D-glucopyranosyl]-β-D-xylopyranosyl}-holosta-7(8),25(26)-dien-16-one(compound 2, named Holotoxin E2). Moreover, CCK-8 assay was used to determine the inhibitory activities of these two new compounds together with four known holostane-type glycosides against MDA-MB-231 cells and HepG2 cells. The results showed that the compounds except Holotoxin E2 had good inhibitory activities against MDA-MB-231(IC50= 2.386—4.686 μmol/L) and HepG2(IC50=5.909—18.860 μmol/L).
