5-脱氮黄素是辅酶F_(420)的类似物,在结构上与黄素类似,但性质有较大差别。研究发现5-脱氮黄素在光激发及电子供体(如醇、胺等)存在下,可以产生具有很高活性和很低电位的5-脱氮黄素自由基。5-脱氮黄素还是一种十分有效的光敏剂,用于太阳能光解水的研究。以5-脱氮黄素为骨架,引入各种配位基,作为人工酶模型模拟金属酶的活性,是辅酶化学模拟的一个引人注意的方向。本文报道两个5-脱氮黄素类化合物与金属离子Mg~(2+)、
5-Deazaflavin is an analogue of Coenzyme F_ (420) which is similar in structure to flavin, but differs greatly in nature. It has been found that 5-deazaflavin can produce 5-deazaflavin with high activity and low potential in the presence of photo-excitation and electron donors (such as alcohols, amines and the like). 5-deazaflavin is also a very effective photosensitizer for solar photolysis water research. Using 5-deazaflavin as a backbone, various ligands are introduced into the artificial enzyme model to simulate the activity of metalloenzymes, which is an attractive direction for chemical simulation of coenzymes. This paper reports two 5-deazaflavin compounds with metal ions Mg 2+,
