A new sesquiterpenoid hydroquinone from the marine sponge Dysidea arenaria.

Detailed chemical investigation of the South China sponge Dysidea arenaria resulted in the isolation of a new sesquiterpenoid hydroquinone, 19-hydroxypolyfibrospongol B (1), along with five known compounds: polyfibrospongol B (2), isosemnonorthoquinone (3), ilimaquinone (4), smenospongine (5) and smenotronic acid (6). The structures were determined by extensive spectroscopic analysis. The in vi...

Marine Sponge Dysidea herbacea revisited: Another Brominated Diphenyl Ether

A pentabrominated phenolic diphenyl ether (1) that has not previously been reported from marine sources has been isolated from Dysidea herbacea collected at Pelorus Island, Great Barrier Reef, Australia. The structure was determined by comparison of NMR data with those of known structurally-related metabolites. NMR spectral assignments for (1) are discussed in context with those of three previo...

Bispuupehenone from the South Chinese Sea sponge Dysidea sp.

Bispuupehenone, C(42)H(54)O(6), formally results from dimerization of puupehenone, which is constructed of sesquiterpene and benzene units. Bispuupehenone was isolated from the South China Sea sponge Dysidea sp. and the single-crystal X-ray diffraction analysis confirmed the previously reported structure. The mol-ecule is located on a twofold axis and the dimerization forms two fused dibenzopyr...

Synthesis and Bioactivity of a Cyclopolypeptide from Caribbean Marine Sponge

Synthesis of a natural proline-rich cyclopolypeptide - rolloamide A [8] was carried out by coupling of tri- and tetrapeptide units Boc-Phe-Pro-Val-OMe and Boc-Pro-Leu-Pro-Ile-OMe after proper deprotection at carboxyl and amino terminals using carbodiimide chemistry in alkaline environment followed by cyclization of linear heptapeptide segment in the presence of base. The structure of synthesize...
