Some of these have been found to possess cytotoxic activity. In continuation of our search for bioactive metabolites from the above sponge, Hippospongia sp., we have further isolated one new sesterterpene, hippospongide D (1). Moreover, our chemical investigation on the sponge Dendoricella flabelliformis which was collected off the North Pole, has led to the isolation of one new natural product sucrose octaacetate (7). The cytotoxic activity of 2-7 was evaluated against two cancer cell lines including HuCCT1 and SW620. The result showed that compounds 2 and 5 exhibited significant cytotoxic activity against HuCCT1 and SW620 cancer cell lines and they had significantly suppressed cell viability and increase cell apoptosis in dose-manner. Compounds 2 and 5 administration increased protein expression of apoptosis by regulates active-form of caspase-3, caspase-7 and PARP. Jui-Hsin Su 蘇瑞欣 2017 學位論文 ; thesis 61 zh-TW |
