摘    要:从一株南海海洋链霉菌属放线菌195-02中分离得到8个化合物,利用波谱技术确定其结构分别为对羟基苯腈(1)、2-甲基-3-呋喃甲酸(2)、2-呋喃甲酸(3)、环(苯丙-苯丙)二肽(4)、环(亮-异亮)二肽(5)、烟酸(6)、吲哚-3-乙酸(7)和邻苯二甲酸二(2-乙基己基)酯(8)。化合物1、3、8为首次从链霉菌属中分离得到,化合物4~7为首次从海洋放线菌中分离得到。活性测试表明化合物4和5在浓度为50μg/ml时,对喉癌细胞hep2抑制率分别为51%和47%,对肝癌细胞hepG2抑制率分别为40%和31%。

Abstract:The metabolites of a marine streptomyces sp. actinomycete (No. 195-02) were studied and eight compounds were isolated from the fermentation liquid, structures were elucidated by spectroscopy methods as p-hydroxy-benzonitrile (1), 2-methyl-furan-3-carboxylic acid(2), furan-2-carboxylic acid (3), cyclo(Phe-Phe) (4), cyclo(Leu-Ileu) (5), nicotinic acid (6), 2-(1H-indol-3-yl) acetic acid (7) and bis(2-ethylhexyl) phthalate (8). The compounds 1, 3 and 8 were firstly isolated from Streptomyces sp., compounds 4 -7 were firstly found from marine actinomycetes. Coumpouds 4 and 5 evidently inhibited the growth of cancer cell lines hepG2 and hep2 at the concentration of 50 microg/ml.
