Ten new clerodane diterpenoid glucosides (1–10) and three known analogues (11–13) were isolated from an EtOAc extract of the stems of Tinospora sinensis. Spectroscopic analyses and chemical methods were used to elucidate the structures of these isolates. The absolute configurations of tinosinenosides A–C (1–3) were established by using experimental and calculated ECD data. Their cytotoxicity against
十个新克罗二萜糖苷(1 - 10)和三个已知类似物(11 - 13)从用EtOAc提取物中分离的茎青牛胆吸虫。使用光谱分析和化学方法阐明了这些分离物的结构。tinosinenosides A-C(的绝对构型1 - 3)通过使用实验和计算ECD数据建立的。测试了它们对人上皮样宫颈癌(HeLa)细胞系的细胞毒性和脂多糖激活的N9小胶质细胞的一氧化氮生成抑制活性。1-脱乙酰基肌苷A(12)对HeLa细胞表现出轻度的细胞毒性,IC 50值为8.35±0.60μM。
