General description

Dipyridamole prevents cellular uptake of adenosine. It functions as an equilibrative nucleoside transporter 1 (ENT1) inhibitor.

Application

Dipyridamole has been used:
  • to perform in vitro growth inhibition assay(40)
  • to determine its ability to prevent uterine myometrial contractions(41)
  • to determine its effects on nicotinamide adenine dinucleotide (NAD+)-induced increase in intracellular adenosine triphosphate (ATP) levels(42)
  • to prevent nicotinamide riboside (NR)-induced axonal protection(43)

Biochem/physiol Actions

Selective inhibitor of phosphodiesterase V (PDE 5); potent coronary vasodilator drug; adenosine transport inhibitor; inhibitor of platelet aggregation.

Articles

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
