obtained from an endophytic fungus Bipolaris sp. L1-2 from Lycium barbarum. Compound 2 is the first example of cochlioquinone derivatives possessing a benzofuran moiety. The structures and absolute configurations of the new compounds were elucidated by spectroscopic data interpretation, single-crystal X-ray diffraction analysis, chemical transformations, and biosynthetic considerations. Compounds 3, 4,
从内生真菌Bipolaris sp。获得了11种新的甲萜类化合物,双polahydroquinones AC(1-3),cochlioquinones IN(4-8和11)以及isocochlioquinones F和G(9和10),以及6种已知的。L1-2来自枸杞。化合物2是具有苯并呋喃部分的科儿喹啉衍生物的第一个例子。通过光谱数据解释,单晶X射线衍射分析,化学转化和生物合成考虑因素,阐明了新化合物的结构和绝对构型。化合物3、4和6-8对NCI-H226和/或MDA-MB-231表现出细胞毒性,IC50值为5.5至9.5μM。
