In this study, fourteen ingenane-type and nine jatrophane-type diterpenoids were isolated from Euphorbia kansui, including seven undescribed compounds. Kansuingenol A-C have the 6,7-vicinal diol moiety, and Kansuijatrophanol A and B possess the 11,12-vicinal diol moiety, both of which are rarely reported. 3,4-(Methylenedioxy) cinnamyl moiety was found for the first time in jatrophane-type diterpenoids, as shown in Kansuijatrophanol C and D. The absolute configurations of seven undescribed compounds have been analyzed and assigned by the modified Mosher's method, Mo2(OAc)4-induced circular dichroism (ICD) method, and CD exciton chirality method. All compounds were screened for their antiproliferative effects against HepG2, MCF-7 and DU145 cell lines. Regarding the HepG2 cells, Kansuijatrophanol C exhibited the most promising inhibition with the IC50 value of 9.47 ± 0.31 μM. Regarding the MCF-7 and DU145 cells, Kansuijatrophanol D exhibited the most promising inhibition with the IC50 values of 6.29 ± 0.18 and 4.19 ± 0.32 μM, respectively.

甘水大戟中的木乃伊烷和麻风树二萜类化合物及其抗增殖作用

在这项研究中,从甘水大戟中分离出 14 种原木薯蓍烷型和 9 种麻风树烷型二萜,包括 7 种未描述的化合物。Kansuingenol AC 具有 6,7-邻二醇部分,Kansuijatrophanol A 和 B 具有 11,12-邻二醇部分,两者都很少报道。3,4-(亚甲二氧基)肉桂基部分首次在麻风树烷型二萜类化合物中被发现,如 Kansuijatrophanol C 和 D 所示。 七种未描述的化合物的绝对构型已通过改进的 Mosher 方法 Mo2(OAc )4 诱导的圆二色性 (ICD) 方法和 CD 激子手性方法。筛选了所有化合物对 HepG2、MCF-7 和 DU145 细胞系的抗增殖作用。关于 HepG2 细胞,Kansuijatrophanol C 表现出最有希望的抑制作用,IC50 值为 9.47 ± 0.31 μM。对于 MCF-7 和 DU145 细胞, Kansuijatrophanol D 表现出最有希望的抑制作用,IC50 值分别为 6.29 ± 0.18 和 4.19 ± 0.32 μM。
