Glucose-based spiro-oxathiazoles as in vivo anti-hyperglycemic agents through glycogen phosphorylase inhibition

Abstract: Spiro-glyco-heterocycles were prepared on a gram scale from a thiolactone obtained by thermolysis of a thiosulfinate. Lowering of glycaemia in diabetic rat models is pointing toward potential new treatment of type 2 diabetes.

“…The phenyl-substituted IXa was reported as the most potent of the three analogues acting at the catalytic site, with a Ki of 1 µM for rabbit muscle glycogen phosphorylase b (rmGPb). Submicromolar Inhibitors with Diverse Scaffolds I (0.35) [15] II X = S (0.16) [25] IV X = N (0.41) [21] III X = CH2 (0.63) [20] V X = CH (0.031) [ Int. J. Mol.…”

“…The debilitating and chronic nature of T2D requires new effective antidiabetic drugs in combination with existing therapies for maintaining normal blood glucose levels . Targeting gluconeogenesis or glycogenolysis in the liver is a validated strategy for developing T2D therapeutics. , Glycogen phosphorylase (GP) catalyzes the first step of glycogen phosphorolysis to G-1-P, and it has been validated as a molecular target for therapeutic intervention in T2D. GP is an allosteric enzyme following the Monod–Wyman–Changeux model. The interconversion between an inactive T conformation (T state) and an active R conformation (R state) is regulated through the action of allosteric effectors.…”
