A large series of variously substituted amino(pyren-1-yl)methylphosphonic acid derivatives was synthesized using a modified aza-Pudovik reaction in 20–97% yields. The fluorescence properties of the obtained compounds were investigated revealing that N-alkylamino(pyren-1-yl)methylphosphonic derivatives are stronger emissive compounds than the corresponding N-aryl derivatives. N-Benzylamino(pyren-1-yl)methylphosphonic acid displayed strong fluorescence (ΦF = 0.68) in phosphate-buffered saline (PBS). The influence of a series of derivatives on two colon cancer cell lines HT29 and HCT116 was also investigated. The most promising results were obtained for N-(4-methoxyphenyl)amino(pyren-1-yl)methylphosphonate, which was found to be cytotoxic for the HCT116 cancer cell line (IC50 = 20.8 μM), simultaneously showing weak toxicity towards normal lymphocytes (IC50 = 230.8 µM).
使用改良的aza-Pudovik反应合成了一大系列不同取代氨基(芘-1-基)甲基膦酸衍生物,产率在20%至97%之间。研究了所得化合物的荧光性质,发现N-烷基氨基(芘-1-基)甲基膦酸衍生物比相应的N-芳基衍生物具有更强的发光性。N-苄基氨基(芘-1-基)甲基膦酸在磷酸盐缓冲盐水溶液中显示出强烈的荧光(ΦF = 0.68)。还研究了一系列衍生物对结肠癌细胞系HT29和HCT116的影响。最有希望的结果是对HCT116癌细胞系具有细胞毒性的N-(4-甲氧基苯基)氨基(芘-1-基)甲基膦酸酯,其IC50值为20.8μM,同时对正常淋巴细胞显示出微弱毒性(IC50 = 230.8µM)。
