edible mushroom Leccinum extremiorientale. The structure of 1 was determined by the interpretation of spectral data. Leccinine A showed protective activity against endoplasmic reticulum stress-dependent cell death. Seven analogues (3–9) of 1 were synthesized in order to evaluate the structure–activity relationship, and the result indicated that the formamide group of 1 was indispensable for the activity
从食用菌Leccinum extremiorientale中分离了Leccinine A(1)和一种已知的化合物(2)。1的结构由光谱数据的解释确定。Leccinine A对内质网应激依赖性细胞死亡具有保护作用。七个类似物(3 - 9)的1中为了评价结构-活性关系进行合成,结果表明,甲酰胺组1是为活动所不可缺少。
