从无活性海洋来源放线菌M15的3株抗生素抗性抗肿瘤活性突变株发酵物中分离鉴定了9个原始菌M15发酵物中没有的代谢产物,其化学结构分别鉴定为1,9-二甲酯-吩嗪(1)、过氧化麦角甾醇(2)、对-甲胺基苯甲酸(3)、染料木素(4)、大豆黄素(5)、N-(2-羟基苯基)-乙酰胺(6)、邻二羟基苯甲酸(7)、尿嘧啶(8)和2-吡咯酸(9)。在初步预试活性测试中,化合物1,2,4,5,7,8对K562细胞示有一定抑制作用,相关活性有待进一步详细测评。
From fermentation broths of three antibiotic-resistant bioactive mutants of a wild-type marine-derived actinomycete strain without antitumor activity,M15,nine compounds 1-9 being newly produced by comparison with their parent M15 were isolated and identified as 1,9-dicarbomethoxy-phenazine(1),ergosterol peroxide(2),4-(methyamino)-benzoic acid(3),genistein(4),daidzein(5),N-(2-hydroxyphenyl)-acetamide(6),2,3-dihydroxybenzoic acid(7),uracil(8) and 1H-pyrrole-2-carboxylic acid(9),respectively.In a preliminary test,1,2,4,5,7 and 8 seem inhibitory on K562 cells,which would be further evaluated in detail.
