[structure: see text] Four new dolabellane-type diterpene alkaloids, nigellamines A(1) (1), A(2) (2), B(1) (3), and B(2) (4), were isolated from the seeds of Nigella sativa. Their absolute stereostructures were determined on the basis of chemical and physicochemical evidence. Nigellamines A(1) (1), B(1) (3), and B(2) (4) were found to show potent lipid metabolism promoting activity in primary cultured
[结构:参见文本]分离了四个新的多拉姆兰型二萜生物碱,nigellamines A(1)(1),A(2)(2),B(1)(3)和B(2)(4)。从Nigella sativa的种子中提取。它们的绝对立体结构是根据化学和物理化学证据确定的。发现Nigellamines A(1)(1),B(1)(3)和B(2)(4)在原代培养的小鼠肝细胞中显示出有效的脂质代谢促进活性,其活性与PPAR相同-α激动剂,克洛贝特。
