Application

P1,P4-Di(adenosine-5′) tetraphosphate ammonium salt has been used as a substrate for nudix hydrolyse. It has also been used as a ATP analog and nudix substrate for cleavage factor II Im25 subunit.

Biochem/physiol Actions

Diadenosine polyphosphate (Ap4A) functions as a second messenger in pancreatic cells. Diadenosine polyphosphate is majorly stored in neuronal cells, thrombocytes and chromaffin. It stimulates phospholipase D, fluctuates intracellular calcium levels, induces nitric oxide release, activates 5′-nucleotidase, and inhibits adenosine kinase activity in vitro. The membrane-bound ectoenzymes in endothelial cells in blood plasma and smooth muscle cell metabolize Ap4A.

Since the infusion of P1,P4-diadenosine 5' tetraphosphate (Ap4A) into animal models induces vasodilation [1,2], the present study was performed to determine whether Ap4A induces the release of nitric oxide (NO) from endothelial cells. Ap4A induced NO release was 4.2-fold greater

Diadenosine polyphosphates released into the extracellular environment influence a variety of metabolic and other cellular activities in a wide range of target tissues. Here we have studied the impact of these novel nucleotides on gluconeogenesis in isolated rat proximal tubules.
