NMR spectra of the mutagen, the compound was deduced to be a PBTA-1 analogue. As with PBTA-1, the mutagen was able to be synthesized from the azo dye 2-[(2-bromo-4, 6-dinitrophenyl)azo]-4-methoxy-5-[(2-hydroxyethyl)amino]acetanilide by reduction and chlorination. Since all spectra of the mutagen isolated from the river water were the same as those of the synthesized form, the structure was concluded
我们先前已经确定了来自日本京都市Nishitakase河的蓝色棉质吸附材料中两个2-苯基苯并三唑诱变剂(PBTA-1和PBTA-2)的化学结构。在本研究中,对流经日本爱知县的日光河中诱变物质的进一步分析,可以分离出一种新的诱变剂。通过各种色谱柱纯化了日光河污水处理厂下方某地点吸附在蓝色棉(3千克)上的物质(2.2克),并通过各种色谱法进行了分离,分离出一种诱变剂(120微克),占总诱变性的11%。根据诱变剂的UV,质量和(1)H NMR光谱数据,推断该化合物为PBTA-1类似物。与PBTA-1一样,诱变剂可以由偶氮染料2-[(2-bromo-4,通过还原和氯化使6-二硝基苯基)偶氮] -4-甲氧基-5-[(2-羟乙基)氨基]乙酰苯胺。由于从河水中分离出的诱变剂的所有光谱都与合成形式的光谱相同,因此推断该结构为2- [2-(乙酰氨基)-4-[(2-羟乙基)氨基] -5-甲氧基苯基] -5-氨
