D1262 P1,P4-Di(adenosine-5′) tetraphosphate ammonium salt ≥95% (HPLC), powder Diadenosine polyphosphate functions as a second messenger in pancreatic cells, stimulates phospholipase D, changes intracellular calcium levels, induces nitric oxide release, activates 5′-nucleotidase, and inhibits adenosine kinase activity in vitro.
Diadenosine polyphosphate is stored in secretory granules of thrombocytes, chromaffin, and neuronal cells. After release into the extracellular space, it affects a variety of biological activities in a wide range of target tissues. It appears to function as a second messenger in pancreatic cells. In rat liver cells. it stimulates phospholipase D and changes intracellular calcium levels. It has been shown to induce nitric oxide release from endothelial cells. In the nervous system it acts through various purinoceptors. It also activates 5′-nucleotidase and inhibits adenosine kinase activity in vitro. Ap4A is metabolized by soluble enzymes in the blood plasma and by membrane-bound ectoenzymes of a number of cell types including endothelial cells, smooth muscle cell.

D6899 Diclofenac sodium salt Diclofenac sodium salt is a nonsteroidal anti-inflammatory drug (NSAID) that acts as a competitive and irreversible inhibitor of prostaglandin synthetase. Its analgesic and anti-inflammatory activities are based on the prevention of the synthesis of arachinodate metabolites via cyclooxygenase inhibition. It is found to hinder the conversion of arachidonic acid to prostaglandins, which mediate inflammatory process. The NSAIDs are found to inhibit both cyclooxygenase enzymes, COX-1 and COX-2, causing undesirable gastrointestinal effect. Diclofenac sodium also functions as a scavenger of free radicals and serves a radioprotective role in restoring supercoiled form of plasmid DNA damaged by radiation back to normal. Diclofenac sodium is oxidized by the donation of electron and transfer of hydrogen atom. It can be a potential radioprotective agent.
Standard NSAID and cyclooxygenase (COX) inhibitor. Major metabolites are 4´-hydroxydiclofenac and 5´-hydroxydiclofenac. Has been used as substrate selective for CYP2C9.
