Three new diphenyl ether derivatives, talaromycins A-C (1-3, resp.), together with six known analogs, 4-9, were isolated from a gorgonian-derived fungus, Talaromyces sp. The structures of the new compounds were determined by analysis of extensive NMR spectroscopic data. All of the isolated metabolites, 1-9, were evaluated for their cytotoxic and antifouling activities. Compound 4 exhibited pronounced
从gorgonian衍生的真菌Talaromyces sp。中分离了三种新的二苯醚衍生物,talalomycins AC(1-3,分别)和六个已知的类似物4-9。通过分析大量NMR光谱数据确定了新化合物的结构。对所有分离的代谢产物1-9的细胞毒性和防污活性进行了评估。化合物4对测试的人类细胞系表现出明显的细胞毒性,IC50值范围为4.3至9.8μM。化合物3、5、8和9对藤壶Balanus amphitrite的幼虫沉降显示出有效的防污活性,EC50值为2.2至4.8μg/ ml。
