), along with two known quinazolinones, 3 and 4, two known 2‐(4‐hydroxyphenyl)acetamides, 5 and 6, and two known N‐(4‐hydroxystyryl)formamides, 7 and 8, were isolated and identified from the culture extract of Penicillium chrysogenum EN‐118, an endophytic fungus obtained from the marine brown alga Sargassum pallidium. The structures of the isolated compounds were elucidated by NMR‐spectroscopic analysis
两种新的三唑,金三唑A和B(分别为1和2)以及两种已知的喹唑啉酮3和4,两种已知的2-(4-羟基苯基)乙酰胺5和6,以及两种已知的N-(4-从产黄青霉EN-118的培养提取物中分离并鉴定了7和8个羟基苯乙烯基甲酰胺,这是一种从海洋褐藻海藻(Sargassum pallidium)获得的内生真菌。分离的化合物的结构通过NMR光谱分析得以阐明,而化合物1的结构得以阐明X射线对它的对溴苯甲酸酯衍生物的晶体学分析证实了这一点。化合物4、5和7对Du145,A-549和HeLa细胞系显示中等程度的细胞毒性。
