从白首乌(Cynanchum bungei Decne)根际土壤青霉(Penicillium sp. HFF 16)中分离得到4个新的吲哚萜类化合物(1-4),分别命名为encindolene A,18-O-甲基-encindolene A,encindolene B和encindolene C,以及3个已知的类似物(5-7)。通过光谱数据和电子圆二色谱(ECD)分析确定了化合物的结构,包括绝对构型。抗炎活性评价显示化合物1-7抑制一氧化氮的产生,IC 50值分别为79.4、49.7、81.3、40.2、86.7、90.1和54.4 μM,并降低脂多糖诱导的RAW 264.7巨噬细胞中肿瘤坏死因子-α、白细胞介素-6的水平。
Four new indole-terpenoids (1–4) named encindolene A, 18-O-methyl-encindolene A, encindolene B, and encindolene C, as well as three known analogs (5–7), were isolated from the fungus Penicillium sp. HFF16 from the rhizosphere soil of Cynanchum bungei Decne. The structures of compounds including absolute configurations were elucidated by spectroscopic data and electronic circular dichroism (ECD) analysis. Anti-inflammatory activity evaluation revealed that compounds 1–7 inhibit the production of nitric oxide with IC50 values of 79.4, 49.7, 81.3, 40.2, 86.7, 90.1, and 54.4 μM, respectively, and decrease the levels of tumor necrosis factor-α, interleukin-6 contents in lipopolysaccharide-induced RAW264.7 macrophages.
