New azo dyes bearing 2-pyridone and benzimidazole moieties were prepared using diazotization of 4-(1H-benzo[d]imidazol-2-yl)aniline and coupling of the obtained diazonium salt with substituted 3-cyano-2-pyridones. Obtained compounds were characterized via UV-Vis, FT-IR, and $^1}$H and $^13}$C NMR spectroscopy as well as by elemental analysis data. The UV-Vis spectra of the synthesized dyes were measured in thirteen solvents of different properties at room temperature. Solvatochromism and tautomerism of novel azo dyes were discussed. An MTT (3,4,5-dimethyl-thiazol-2-yl)-2,5-diphenyl tetrazolium bromide) test was performed to prove the biocompatibility of the investigated dyes. The investigated dyes exhibited satisfying antiproliferative activities against both tumor cell lines, MDA-MB-231 and HCT-116, demonstrating the potent capacity for treatment of tumors.
含有2-吡啶酮和苯并咪唑结构的新型偶氮染料是通过4-(1H-苯并[d]咪唑-2-基)苯胺的重氮化以及所得的重氮盐与取代的3-氰基-2-吡啶酮的偶联反应制备的。所得化合物通过UV-Vis、FT-IR、$^1}$H和$^13}$C NMR光谱以及元素分析数据进行表征。合成的染料在室温下在十三种不同性质的溶剂中的UV-Vis光谱被测定。讨论了新型偶氮染料的溶剂化色变和互变异构现象。通过MTT(3,4,5-二甲基噻唑-2-基)-2,5-二苯基四唑溴盐)测试证明了所研究染料的生物相容性。所研究的染料对MDA-MB-231和HCT-116两种肿瘤细胞系表现出满意的抗增殖活性,显示出强大的肿瘤治疗能力。
