Chemical investigation of Penicillium sp. GDGJ-N37, a Sophora tonkinensis-associated fungus, yielded two new azaphilone derivatives, N-isoamylsclerotiorinamine (1) and 7-methoxyl-N-isoamylsclerotiorinamine (2), and four known azaphilones (3–6), together with two new chromone derivatives, penithochromones X and Y (7 and 8). Their structures were elucidated based on spectroscopic data, CD spectrum, and
青霉菌属 GDGJ-N37(一种与苦参相关的真菌)的化学研究产生了两种新的氮杂酮衍生物,N-异戊基菌核蛋白胺 (1) 和 7-甲氧基-N-异戊基菌核蛋白胺 (2),以及四种已知的氮杂菌酮 (3-6),以及两种新的铬酮衍生物,喷铬酮 X 和 Y(7 和 8)。它们的结构是根据光谱数据、CD 光谱和半合成来阐明的。硬化萝胺 (3) 对枯草芽孢杆菌和痢疾链球菌显示出显着的抗菌活性,并且还对 P. theae、C. miyabeanus 和 E. turcicum 显示出最有效的抗植物病原真菌活性。
