A new metal-coordinative flavin(2,4,7-trimethylquino[8,7-g]pteridine-9,11(7H,10H)-dione: (1)) which has a phenanthroline-like skeleton within the molecular structure was synthesized. Being different from conventinal flavins, the new flavin showed a significant affinity toward metal ions and the absorption spectra were sensitively affected by added metal ions. The spectral patterns were classified into
一种新的金属配位黄素(2,4,7-trimethylquino[8,7-g]pteridine-9,11(7H,10H)-dione: (1)) 在分子结构中具有类似菲咯啉的骨架是合成的。与传统的黄素不同,新黄素对金属离子表现出显着的亲和力,吸收光谱受添加金属离子的敏感影响。光谱模式分为三种类型,分别分配给不同的配位结构。通过二氢吡啶衍生物、苯肼和 L-抗坏血酸的氧化证明,络合的金属离子能够“激活”作为氧化剂的 1。与 Zr4+ 和 Fe3+ 的配合物甚至在环境温度下氧化醇。出乎意料的是,发现四面体配位金属如 Cd2+、Zn2+、
