標題: | Sesquiterpenoids and Artificial 19-Oxygenated Steroids from the Formosan Soft Coral Nephthea erecta | 作者: | Cheng, Shi-Yie CHANG-FENG DAI Duh, Chang-Yih |
公開日期: | 2007 | 卷: | 70 | 期: | 9 | 起(迄)頁: | 1449-1453 | 來源出版物: | Journal of Natural Products | 摘要: | Chemical investigations on the acetone and MeOH solubles of the soft coral Nephthea erecta have afforded five new sesquiterpenoids (1-5), one known sesquiterpene, kelsoene (6), and two known 19-oxygenated steroids (10 and 11). In addition, three unexpected artificial 19-oxygenated steroids (7-9) were obtained by letting 10 and 11 stand in CDCl3 for prolonged periods of time. The structures of 1-9 were elucidated by extensive spectroscopic analyses, and their cytotoxicity against selected cancer cells was measured in vitro. ? 2007 American Chemical Society and American Society of Pharmacognosy. |
