geometry around ruthenium was assigned in all complexes using electronic spectral analysis and EPR measurements. All compounds were evaluated for cytotoxicity activity against S. pombe cells at a cellular level. A comparative study of cellular level cytotoxicity values of all the compounds indicated that all the metal complexes showed better activity against S. pombe cells compared to the free heterocyclic
合成了一系列基于三取代吡唑啉核的[Ru(L 1-7)2 ]·(PF 6)3(L 1-7 =杂环吡唑啉衍生物)型Ru(III)配合物。,其电子光谱,电导率测量,热重分析(TGA),电子顺磁共振(EPR),傅立叶变换红外(FT-IR)光谱和质谱(MS)。使用电子光谱分析和EPR测量,在所有配合物中指定了钌周围的八面体几何形状。评价所有化合物对粟酒裂殖酵母的细胞毒性活性细胞水平的细胞。对所有化合物的细胞水平细胞毒性值的比较研究表明,与游离杂环吡唑啉配体相比,所有金属配合物均表现出对粟酒裂殖酵母细胞更好的活性。所有的复合物都是良好的体外细胞毒性剂,LC 50值在5.57–8.01 mg L -1范围内。还针对它们对五种不同微生物的体外抗菌行为进行了筛选。用吸收滴定法检查它们与鲱鱼精子(HS)DNA的相互作用(K b = 0.37–5.02×10 5 L mol -1)和粘度测量研究,并提出了DNA
