Abstract

Two new diketopiperazines, named diphenylalazine C (1) and epicoccin U (2), together with six known compounds (3-8) were isolated from the EtOAc extract of the fermentation broth of the tin mine tailings-derived fungus Schizophyllum commune YIM DT 10058. Their structures were elucidated by detailed analysis of spectroscopic data and comparison with related known compounds. Compounds 1 and 2 exhibited weak antibacterial and cytotoxic activities.

摘要

从锡矿尾矿来源的真菌裂褶菌YIM DT 10058发酵液的乙酸乙酯提取物中分离得到两个新的二酮哌嗪，命名为二苯基丙氨酸嗪C（1）和表棒曲霉素U（2），以及六个已知化合物（3 - 8）。通过对光谱数据的详细分析并与相关已知化合物进行比较，阐明了它们的结构。化合物1和2表现出较弱的抗菌和细胞毒性活性。
