This study investigated the cytotoxic activities of α-Santonin compound which extracted from Dysidea avara. In ...
متن کاملA 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...
متن کاملBispuupehenone 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...
متن کاملSesquiterpene aminoquinones, from a marine sponge, induce erythroid differentiation in human chronic myelogenous leukemia, K562 cells.
A new sesquiterpene aminoquinone, 5-epi-smenospongorine, together with nine known sesquiterpene quinone/phenols, was isolated as differentiation-inducing substances to K562 cells into erythroblast from the marine sponge Dactylospongia elegans. The structure-activity relationship study of these compounds clarified that the quinone skeleton is indispensable and the amino group plays an important ...
