METHOD FOR PREPARING SIALIC ACID DERIVATIVE

The present invention relates to a method for preparing a sialic acid derivative characterized by performing both of a process for preparing CMP-N-acetylneuraminic acid using N-acetyl-D-glucosamine and a process for preparing the sialic acid (neuraminic acid) derivative that combines a sialic acid w...

Zusammenfassung:	The present invention relates to a method for preparing a sialic acid derivative characterized by performing both of a process for preparing CMP-N-acetylneuraminic acid using N-acetyl-D-glucosamine and a process for preparing the sialic acid (neuraminic acid) derivative that combines a sialic acid with a galactose derivative or a lactose derivative, together, in one reactor. According to the method for preparing a sialic acid derivative of the present invention, expensive cytidine 5′-monophosphate (CMP) is capable of being recycled in a reactor, such that an amount of the CMP introduced into the reactor may be reduced, and the sialic acid derivative is capable of being prepared at a significantly high efficiency by using cheap N-acetyl-D-glucosamine, and pyruvate as substrates.
