Problems solved by technology

The above work is based on the NAD + Based on the chemical modification of the original structure, it is difficult to overcome the shortcomings of its chemical instability, chemical synthesis and separation difficulties, etc.
[0009] H.C.Lo et al. (Inorg.Chem.2001, 40, 6705-6716.) used methanol as a substitute for adenosine monophosphate (AMP) and nicotinamide mononucleotide under DCC / DMAP to synthesize NAD + analog However, this method has low yield, many by-products, difficult separation, and the product is easily decomposed during the separation process.
In addition, if other alcohols are used as a substitute for the adenosine monophosphate (AMP) part, no suitable solvent can be found to dissolve nicotinamide mononucleotide, and the 2' and 3' hydroxyl groups on the sugar ring will also participate in the reaction. So this method is not suitable for the synthesis of NAD of the present invention + analog
[0010] H.C.Lo et al. (Angew.Chem.Int.Ed.2002, 41, 478-481.) reported an example of using the above analogs as cofactors of horse liver dehydrogenase (HLADH) to reduce ketones to chiral alcohols, However, the reducing agent used is the rare metal Rh, which is expensive, cumbersome to operate, sensitive to air, and the structure of the cofactor is too simple, and the combination with the enzyme is not tight enough.
