Abstract

Isoxestovanin A (6), xestovanin B (7), xestovanin C (8), dehydroxestovanin A (9), epidehydroxestovanin A (10), dehydroxestovanin C (11), and secodehydroxestovanin A (12), seven new triterpenoid glycosides, have been isolated from the Northeastern Pacific sponge Xestospongia vanilla. The structures of the metabolites were determined by a combination of spectroscopic analysis and chemical degradation. The aglycone of 6 has the new isoxestovanane triterpenoid carbon skeleton. Compounds 7, 8, and 11 are the first X. vanilla triterpenoid glycosides known to contain three monosaccharide subunits.
