标题 :Synthesis of nicotinamide cofactors
发明人：WHITESIDES GEORGE; WALT DAVIS R
权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:Nicotinamide cofactors are prepared in a process of reacting ribose -5- phosphate with a basic material selected from the group consisting of ammonia, primary and secondary amines in a polar non-aqueous solvent, reacting the resultant 1-ribosylamine -5- phosphate with a pyridinium salt and reacting the resultant nicotinamide mononucleotide with adenosine triphosphate in the presence of nicotinamide adenine dinucleotide pyrophosphorase to produce nicotinamide adenine dinucleotide which can be used directly in crude form without further purification in co-factor - requiring enzymatic reactions. The nicotinamide adenine dinucleotide pyrophosphorase may be immobilized on a solid support.
