for the CT reagents in the same order. Elucidation of the chemical structure of the solid CT complexes formed via reaction between the drug under study and π-acceptors was done using elemental, thermal analyses, IR, 1H NMR and mass spectrometry. X-ray diffraction was used to estimate the crystallinity of the CT complexes. Their biological activities were screened against different bacterial and fungal
开发了一种简单,准确和耐用的分光光度法测定非诺洛芬钙药物(FPC)。所提出的方法基于FPC药物(作为正电子供体)与2,3-二氯-5,6-二氰基-1,4-苯醌(DDQ),2,4,6的电荷转移(CT)反应-三硝基苯酚(苦味酸,PA)或1,2,5,8-四羟基蒽醌(奎纳利扎林,QZ)(作为π受体)产生高度着色的电荷转移络合物。已经仔细优化了影响反应的不同变量,例如试剂浓度,温度和时间,以实现最高的灵敏度。使用DDQ,PA和QZ CT试剂分别在2-60、0.6-90和4-30μgmL-1的浓度范围内遵守比尔定律,相关系数为0.9986、0.9989和0.997,检出限为1.78、0.48和2。对于CT试剂,相同顺序为6μgmL-1。使用元素分析,热分析,IR,1H NMR和质谱分析了通过研究中的药物与π受体之间的反应形成的固体CT络合物的化学结构。X射线衍射用于估计CT络合物的结晶度。针对不同的细菌
