摘要: 采用多种色谱法从深海来源真菌Alternaria tenuissma DFFSCS013的发酵产物中分离得到了6个混源萜类化合物,利用波谱学方法鉴定了它们,结构分别鉴定为Tricycloalternarene J (1)、Tricycloalternarene 2b (2)、Tricycloalternarene 1b (3)、Tricycloalternarene 6b (4)、Tricycloalternarene 3b (5)、Tricycloalternarene 1a (6)。对这6个化合物进行了抗菌和抗真菌活性测试,在100 μg/纸片浓度下,只有化合物5有显著抑制大肠杆菌和枯草芽孢杆菌生长的作用,其它化合物都活性微弱。这是首次报道化合物1~2和4~5的抗细菌活性、以及5的抗真菌活性。

Abstract: Six known compounds were isolated from the fermentation products of the deep-sea derived fungus Alternaria tenuissma DFFSCS013.These compounds were identified as tricycloalternarene J (1),tricycloalternarene 2b (2),tricycloalternarene 1b (3),tricycloalternarene 6b (4),tricycloalternarene 3b (5),and tricycloalternarene 1a (6) by spectroscopic analyses.All of them were tested for antibacterial and antifungal activities.Only compound 5 showed obvious inhibition activity against the growth of Escherichia coli and Bacillus subtilis,while other compounds showed weak activity against indicators at 100 μg/dics.This is the first time to report the antibacterial activity of compounds 1-2 and 4-5 and the antifungal activity of 5.

Key words: deep-sea derived fungus, Alternaria tenuissma, tricycloalternarene
