Description
2-Deoxy-D-glucose (154-17-6) is a synthetic glucose analog with extensive biological effects. It is commonly thought of as an inhibitor of glycolysis, but its metabolic effects are wide-ranging. 2-Deoxy-D-glucose competitively inhibits glucose uptake via its metabolite 2-Deoxy-D-glucose-6-phosphate, which inhibits hexokinase and phosphoglucose-isomerase leading to decreased ATP production, cell cycle blockage, decreased cell growth and ultimately cell death.1,2

Uses
2-deoxy-D-Glucose is a non-metabolizable glucose analog that inhibits phosphorylation of glucose by hexokinase, the first step of glycolysis. This results in the depletion in cellular ATP, the inhibition of protein glycosylation, and the disruption of ER quality control by inducing the unfolded protein response. 2-deoxy-D-Glucose has been shown to cause cell cycle inhibition and cell death in in vitro models of hypoxia, induce autophagy, increase reactive oxygen species production, activate AMPK, and block tumor cell growth in animal models.[Cayman Chemical]
Biochem/physiol Actions
2-Deoxy-D-Glucose (2-Deoxyglucose) is a glucose analog that inhibits glycolysis via its actions on hexokinase, the rate limiting step of glycolysis. It is phosphorylated by hexokinase to 2-DG-P which can not be further metabolized by phosphoglucose isomerase. This leads to the accumulation of 2-DG-P in the cell and the depletion in cellular ATP. In vitro, 2-Deoxyglucose has been shown to induce autophagy, increase ROS production, and activate AMPK.
Purification Methods
Crystallise 2-deoxy--D-glucose from MeOH/Me2CO, Me2CO or butanone to give a mixture of and anomers, m 142-144o, [] 18 +38o (35minutes) to +46o (c 0.5, H2O). Recrystallisation from isoPrOH gives mainly the -anomer m 134-136o , [ ] D +156o to +103o (c 0.9, pyridine). 1H NMR studies showed that at 44o in D2O the solution contained 36% of -pyranose and 64% of -pyranose sugar, but furanose structures were undetectable.
