ABSTRACT:
Disclosed is a novel .alpha.-glycosyl derivative of a catecholamine or its salt, said .alpha.-glycosyl derivative being prepared by allowing a saccharide-transferring enzyme together with or without glucoamylase to act on a solution containing an .alpha.-glycosyl saccharide and one of catecholamines in order to form an .alpha.-glycosyl derivative of said catecholamines, and recovering the resultant .alpha.-glycosyl derivative. The .alpha.-glycosyl derivative overcomes conventional drawbacks of catecholamines, and does not substantially exhibit or have a reducing activity and undesirable toxicity, but has a relatively-high stability and exerts the inherent physiological activities of catecholamines in vivo. Thus, the .alpha.-glycosyl derivative is advantageously used as a variety of pharmaceuticals in the form of an injection, tablet, etc.
