Description:Acadesine is the prototype of a new class of compounds termed adenosine regulating agents. Acadesine is a purine nucleosid analogue that enters the myocyte and is immediately phosphorylated to ZMP (AICA ribotide), which is further metabolised to Inosine mono-phosphate (an intermediate in the synthesis ofadenosine triphosphate (ATP) and guanosine triphos-phate).
Claims that acadesine may serve as a substrate for ATP synthesis and result in repletion of myocardial ATP were supported by some studies and refuted by others. Because acadesine may be a precursor in the synthesis of myocardial ATP it was proposed as a possible agent of myocardial protection during ischaemia, particularly because myocardial ATP depletion has been linked to cell death.
Uses:AICAR is a nucleoside analogue that is able to enter nucleoside pools and is able to significantly increase levels of adenosine during periods of ATP breakdown. Adenosine-regulating agents (ARAs) hav e been recognized for therapeutic potential in myocardial ischemia. Cardioprotective.
