Nitrofurantoin (1-([(5-nitrofuran-2-yl)methylene]amino)imidazolidine-2,4-dione), a widely used drug and also a well-known bacterial mutagen, inhibits DNA synthesis in mitochondria from 48 h etiolated seedlings of Vigna sinensis (Linn.) Savi (snake bean). The effect appears at the level of the uptake of radioactive deoxynucleoside triphosphates by the plant mitochondria. Nitrofurantoin does not inhibit DNA synthesis in vitro by homogeneous Escherichia coli DNA polymerase I and DNA polymerase from avian-myeloblastosis virus. No specific nitroreductase activity could be detected in mitochondria.
呋喃妥因(1-([(5-硝基呋喃-2-基)亚甲基]氨基)咪唑烷-2,4-二酮)是一种广泛使用的药物,也是一种著名的细菌诱变剂,它能抑制豇豆(Vigna sinensis (Linn.) Savi,蛇豆)48小时黄化幼苗线粒体中的DNA合成。这种作用出现在植物线粒体摄取放射性脱氧核苷三磷酸的水平上。呋喃妥因在体外不抑制纯大肠杆菌DNA聚合酶I和禽成髓细胞瘤病毒DNA聚合酶的DNA合成。在线粒体中未检测到特异性硝基还原酶活性。
