The following compounds were isolated from acetate extracts of 7951 solid cultures: demethylchaetocochin C (1) and chaetoperazine A (3), two new epipolythiodioxopiperazine (ETP) alkaloids, a novel pyridine benzamide, 4-formyl--(3'-hydroxypyridin-2'-yl) benzamide (6), and three known ETP derivatives (2, 4, and 5). The structures of these compounds were determined using extensive spectroscopic data analysis. Compounds 1-3, and 6, inhibited the growth of MCF-7, MDA-MB-231, H460 and HCT-8 cells with an IC of 4.5 to 65.0 μM.
从7951固体培养物的乙酸乙酯提取物中分离出以下化合物：去甲基毛壳素C（1）和毛壳哌嗪A（3），两种新的表聚硫代二氧哌嗪（ETP）生物碱，一种新型吡啶苯甲酰胺，4-甲酰基-（3'-羟基吡啶-2'-基）苯甲酰胺（6），以及三种已知的ETP衍生物（2、4和5）。通过广泛的光谱数据分析确定了这些化合物的结构。化合物1-3和6对MCF-7、MDA-MB-231、H460和HCT-8细胞的生长具有抑制作用，半数抑制浓度（IC）为4.5至65.0μM。
