investigation of the onion pathogenic fungus Alternariaporri resulted in the isolation of two new phthalides named zinnimide (2) and deprenylzinnimide (8), along with a new bianthraquinone, alterporriol F (10). The structures of the new metabolites were characterised by spectroscopic analysis and chemical degradation. Of the new compounds isolated, alterporriol F was highly cytotoxic towards HeLa and KB
对洋葱病原性真菌Alternaria porri的化学研究导致分离出了两种新的邻苯二甲酸酯,分别称为zinnimide(2)和deprenylzinnimide(8),以及一种新的比蒽醌,Alterporriol F(10)。通过光谱分析和化学降解来表征新代谢物的结构。在分离出的新化合物中,甲三醇F对HeLa和KB细胞具有高度细胞毒性,IC 50值为6.5和7.0 µg mL -1。
