从天山驼舌草(Stelleropsis tianschanica)中分离得到了4种新的瑞香烷型二萜,命名为天茶萜C - F(1 - 4)以及6种已知的二萜。通过化学和光谱分析阐明了它们的结构。利用计算和实验电子圆二色谱(ECD)方法的比较来确定新化合物的绝对构型。此外,对化合物1 - 10针对HGC - 27细胞系的细胞毒活性进行了评估;结果表明化合物2具有较强的细胞毒活性,其半数抑制浓度(IC50)值为8.8 µM,该活性优于顺铂(13.2 ± 0.67 µM)。
Four new daphnane-type diterpenes named tianchaterpenes C-F (1–4) and six known ones were isolated from Stelleropsis tianschanica. Their structures were elucidated based on chemical and spectral analyses. The comparisons of calculated and experimental electronic circular dichroism (ECD) methods were used to determine the absolute configurations of new compounds. Additionally, compounds 1–10 were evaluated for their cytotoxic activities against HGC-27 cell lines; the results demonstrate that compound 2 had strong cytotoxic activities with IC50 values of 8.8 µM, for which activity was better than that of cisplatin (13.2 ± 0.67 µM).
