phenanthroindolizidine alkaloids, namely tylohirsutinine, 13a-methyltylohirsutine, 13a-methyltylohirsutinidine, tylohirsutinidine and 13a-hydroxysepticine, isolated from Tylophora hirsuta together with two unidentified bases are described. Structural studies indicate that the first four alkaloids possess the dibenzo [f, h ]-pyrrolo-[1,2 b ]isoquinoline skeleton present in other Tylophora species, but differ
摘要 描述了从 Tylophora hirsuta 中分离得到的五种新型菲吲哚里西啶生物碱,即 tylohirsutinine、13a-methyltylohirsutinine、13a-methyltylohirsutinidine、tylohirsutinidine 和 13a-hydroxysepticine,以及两种未知的碱基。结构研究表明,前四种生物碱具有其他 Tylophora 物种中存在的二苯并 [f, h ]-吡咯并 [1,2 b ] 异喹啉骨架,但在环 E 中存在不饱和度或存在角甲基功能。第五种生物碱已被证明是脓毒碱的 13a-羟基类似物。
