摘要:

对一株土壤来源的链霉菌Streptomyces sp.CPCC 203679进行次生代谢产物研究。采用正反相硅胶柱、Sephadex LH-20凝胶柱及半制备高效液相色谱等技术,从菌株CPCC 203679的发酵物中分离纯化了9个化合物,通过波谱学方法分析鉴定其结构,包括1个新脂肪酸类化合物:(3S)-3-羟基-8-甲基-5-氧壬酸(1)和8个已知化合物:N-[2-(4-对羟基苯酚)乙基]乙酰胺(2)、3,3-二-(3′-吲哚)丙烷-1,2-二醇(3)、环(L-亮-L-脯)二肽(4)、环-(L-苯丙-L-酪)二肽(5)、环(L-酪-L-脯)二肽(6)、环(L-苯丙-L-脯)二肽(7)、环(L-异亮-L-脯)二肽(8)、2,3-dihydroxypropyl(9E,11E)-13-oxooctadeca-9,11-dienoate(9)。化合物3为首次从土壤来源的链霉菌中分离得到。对分离得到的化合物1~8进行了体外抗菌活性和细胞毒活性评价,药理活性评价结果显示,化合物1~8均未显示出明显的抗菌和抗肿瘤活性。

Abstract:

The secondary metabolites of a soil-derived Streptomyces sp. CPCC 203679 were investigated. The fermentation extract of strain CPCC 203679 were isolated by silica gel column,Sephadex LH-20 gel column,and high performance liquid chromatography,which led to the isolation of nine compounds,including a new fatty acid,(3S)-3-hydroxy-8-methyl-5-oxononanoic acid (1) and eight known compounds,N-[2-(4-hydroxyphenyl)ethyl]acetamide (2),3,3-bis(3′-indolyl)propane-1,2-diol (3),cyclo-(L-Leu-L-Pro) (4),cyclo-(L-Phe-L-Try) (5),cyclo-(L-Try-L-Pro) (6),cyclo-(L-Phe-L-Pro) (7),cyclo-(L-Ile-L-Pro) (8),2,3-dihydroxypropyl(9E,11E)-13-oxooctadeca-9,11-dienoate (9).Their structures were elucidated by spectroscopic methods and comparison with reported literatures. Compound 3 was obtained from the soil-derived Streptomyces for the first time.The isolated compounds 1-8 were evaluated for their antibacterial and cytotoxic activities.The biological activity results showed that all compounds had no antibacterial and cytotoxic activities.

Key words: Streptomyces, secondary metabolites, fatty acid, alkaloid, cyclic dipeptide
