isolation of fifteen new N-glycosides of indolo[2,3-a]carbazoles designated tjipanazoles A1, A2, B, C1, C2, C3, C4, D, E, F1, F2, G1, G2, I and J. The structures of the alkaloids were determined by physical methods, chemical degradation and synthesis. Tjipanazole J is the only compound having the pyrrolo[3,4-c] ring of previously described indolo[2,3-a]carbazoles.
生物活性指导的蓝藻Tolypothrix tjipanasensis提取物的分离已导致分离出十五种新的吲哚并[2,3-a]咔唑N-糖苷,分别命名为tjipanazoles A1,A2,B,C1,C2,C3,C4,D ,E,F1,F2,G1,G2,I和J。通过物理方法,化学降解和合成方法确定生物碱的结构。吉帕唑J是唯一具有前述吲哚并[2,3-a]咔唑的吡咯并[3,4-c]环的化合物。
