从新生烟曲霉（Aspergillus novofumigatus）CBS 117520中分离到两个新的二酮哌嗪代谢产物：novoamauromine（1）和ent-cycloechinulin（2）。化合物1和2的结构是在光谱和化学研究的基础上确定的，其中包括对amauromine（3）和cycloechinulin（4）的光谱和理化数据的详细比较。
Two new diketopiperazine metabolites, novoamauromine (1) and ent-cycloechinulin (2) have been isolated from Aspergillus novofumigatus CBS117520. The structures of 1 and 2 were established on the basis of spectroscopic and chemical investigation, including a detailed comparison of the spectroscopic and physico-chemical data of amauromine (3) and cycloechinulin (4).
