aqueous media in absence of phenolic-OH. Compounds 3 and 9 were found to be clear pH-dependent between pH = 4.0 and 10.0, and could be used as acid-base indicators to measure intracellular pH. Compounds 6, 9, 10 all have carboxylic acid functionalities, which could be activated and used to conjugate the dyes to biomolecules. In addition, compounds 6 and 9 with good solubility in aqueous media were used
通过有效的合成策略,以多重图规模合成了恶嗪染料的衍生物。一个实际的路线选择,以制备化合物6,9和10,特别是水溶性的化合物6中更好的产率比报道获得,和化合物10是在水性介质中不溶性的在不存在酚-OH。发现化合物3和9在pH = 4.0和10.0之间具有明显的pH依赖性,可以用作测量细胞内pH的酸碱指示剂。化合物6,9,10它们都具有羧酸官能团,可以被活化并用于将染料与生物分子结合。此外,使用在水性介质中具有良好溶解度的化合物6和9来开发一种简单,快速,安全,高灵敏度的染色方法,以检测热固性涂片上产生PHAs的细菌,这一点已通过PHA颗粒的荧光图像得到证实。菌。
