1,4-Dideoxy-1,4-imino-D-arabinitol (DAB) functions as an inhibitor of glycogenphosphorylase, a crucial enzyme in glycogenolysis, demonstrating the ability to hinder this process in isolated liver cells (IC50= 1.0 µM) and cerebral cortex and cerebellum homogenates (IC50s = 463 and 383 nM, respectively). Employed extensively in different animal models, DAB inhibits glycogenolysis within the liver and brain.
Morolic acid and moronic acid have shown sustained antidiabetic and antihyperglycemic action possibly mediated by an insulin sensitization with consequent changes of glucose, cholesterol and triglycerides, in part mediated by inhibition of 11β-HSD 1. Moro
