A high yielding, simple synthesis is described starting from D-glucose to produce gram quantities of a glucopyranosylidene-spiro-thiohydantoin. This compound efficiently inhibited the activity of rat liver glycogen phosphorylase a; moreover, it also activated phosphorylase phosphatase which, in turn, decreased the amount of glycogen phosphorylase a. Both effects result in the inhibition of glycogen mobilization and the formation of glucose from glycogen. (C) 2000 Elsevier Science Ltd. All rights reserved.
