摘要:

以1,10-邻菲啰啉为基本骨架设计合成了6种咪唑[4,5-f][1,10]邻菲啰啉的衍生物(3a~3f); 研究了目标化合物对蛋白酪氨酸磷酸酶1B(PTP1B)的抑制作用, 其最高抑制率可达(84.56±1.78)%, 是潜在的PTP1B的抑制剂药物; 基于1,10-邻菲啰啉优良的光学性能, 通过荧光测试研究了不同pH对化合物3a~3f的影响, 探讨了化合物在Britton-Robison(B-R)缓冲溶液中的质子化和去质子化现象; 以硫酸奎宁为参比, 计算了相应的荧光量子产率. 结果表明, 目标化合物均有较高的荧光量子产率, 最高可达0.53.

Abstract:

Six kinds of imidazo[4,5-f][1,10]phenanthroline derivatives(3a—3f) were designed and synthesized based on [1,10]phenanthroline skeleton. The inhibition of the target compounds on PTP1B was studied and the highest inhibition rate could be up to (84.56±1.78)%. The results indicated that the target compounds could be used as the potential PTP1B inhibitors and provide important therapy reference for the modern Ⅱ diabetes and obesity. Owing to the excellent optical performance of 1,10-phenanthroline, the effects of pH on the luminescence properties of the target products(3a—3f) were also studied and the phenomenon of the protonation and deprotonation in the B-R buffer solution were explored. Taking quinine bisulphate as a refe-rence, the highest luminescence quantum yield of compounds 3 was 0.53. With the increase in pH value, the luminescence intensity of compounds 3 increased. In the range of pH=6—8, compounds 3 gave a strong and steady luminescence. However, the luminescence intensity of compounds 3 reduced when pH value was higher than 8. As a result, compounds 3 could be used as pH luminescence sensing probe.

Key words: Imidazo[4,5-f][1,10]phenanthroline, PTP1B inhibitor, pH-Induced luminescence sensing probe, Luminescence quantum yield
