The recognition properties of 7,8-dimethyl flavin analogues by bile acid-based receptors that contain 2,6-diaminopyridine and the dioctylamide of 2,6-diaminopyridine in CHCl3 were determined. The results show that the bile acid-based receptors bind 7,8-dimethyl flavin analogues less effectively as compared to 7,8-unsubstituted flavins reported earlier, which is contrary to the known fact that the association
测定了含有 2,6-二氨基吡啶的胆汁酸受体和 2,6-二氨基吡啶在 CHCl3 中的二辛酰胺对 7,8-二甲基黄素类似物的识别特性。结果表明,与早先报道的 7,8-未取代的黄素相比,基于胆汁酸的受体结合 7,8-二甲基黄素类似物的效率较低,这与已知的事实相反,即缔合常数随着供电子能力的增加而增加黄素类似物 7 位和 8 位的取代基。
