Potential therapeutic applications of fructose-1,6-diphosphate.

Ischaemia-related tissue injury is the leading cause of death in developed countries. Drugs that can reduce ischaemic injury would be beneficial in treatment of myocardial infarction (MI), surgical trauma and stroke. Fructose-1,6-diphosphate (FDP) is a key intermediate in anaerobic glycolysis and is the product of the major regulatory enzyme in the pathway (phosphofructokinase). Preclinical and clinical data suggest that FDP has substantial cytoprotective effects in a variety of ischaemia-reperfusion injury scenarios. Evidence indicates that FDP has a direct effect on ATP pools, reduces ischaemia-induced tissue damage and has positive inotropic effects on heart function. The clinical data suggest that FDP may be a useful drug in a variety of ischaemic and inflammatory clinical settings where acute management of tissue injury is desired. Potential uses include: iv. administration for the reduction of ischaemic injury in sickle cell anaemia, bypass surgery, congestive heart failure, myocardial infarction, as well as organ preservation in transplants.
