2-脱氧-D-葡萄糖, 2-Deoxy-D-Glucose

2-deoxy-D-Glucose is a glucose antimetabolite and an inhibitor of glycolysis. It inhibits hexokinase, the enzyme that converts glucose to glucose-6-phosphate, as well as phosphoglucose isomerase, the enzyme that converts glucose-6-phosphate to fructose-6-phosphate. 2-deoxy-D-glucose (16 mM) induces apoptosis in SK-BR-3 cells, as well as inhibits the growth of 143B osteosarcoma cells cultured under hypoxic conditions when used at a concentration of 2 mg/ml. In vivo, 2-deoxy-D-glucose (500 mg/kg) reduces tumor growth in 143B osteosarcoma and MV522 non-small cell lung cancer mouse xenograft models when used alone or in combination with doxorubicin or paclitaxel.

2-Deoxyglucose, also known as 2-deoxy-D-mannose or D-2DGLC, belongs to the class of organic compounds known as fatty alcohols. These are aliphatic alcohols consisting of a chain of a least six carbon atoms. 2-Deoxyglucose has been primarily detected in urine. Within the cell, 2-deoxyglucose is primarily located in the cytoplasm. 2-Deoxyglucose exists in all eukaryotes, ranging from yeast to humans.

2-deoxyglucose is predominantly used as a diagnostic agent in its radiolabelled form (fluorine-18 is used as the radiolabel). By using positron emission tomography (PET), radiolabelled 2-deoxyglucose can determine glucose metabolism, which is altered in diseases such as cardiovascular disease, tumors, and Alzheimer's disease. Therapeutically, 2-deoxyglucose is an investigational drug that is being studied as an anticancer and antiviral agent. Concerning the former, 2- deoxyglucose was used as an adjunct to chemotherapy and radiotherapy in the treatment of solid tumors (lung, breast, pancreas, head, neck, and gastric tumors). The exact mechanisms of action of 2-deoxyglucose is still being investigated, but it is known that in hypoxic cancer cells, 2-deoxyglucose is a glycolysis inhibitor that prevents ATP production and, ultimately, cell survival. With respect to antiviral therapy, 2-deoxyglucose was shown to be effective against herpes simplex virus by affecting the virus' ability to penetrate cells. As an experimental drug, 2-deoxyglucose was demonstrated to work as an anticonvulsant in temporal lobe epilepsy. In this condition, 2-deoxyglucose represses the expression of certain proteins that are at high levels after a seizure. Although there are several possible therapeutic indications for 2-deoxyglucose, presently there is no approved indication for 2-deoxyglucose as a therapeutic agent.
