Gene Information

human ... PDE3A(5139) , PDE3B(5140)

Application

Trequinsin has been used as a PDE3 inhibitor in rat juxtaglomerular cells. This study reported that trequinsin can enhance cellular cAMP content, forskolin-induced cAMP synthesis, and renin release in cells.

Biochem/physiol Actions

Trequinsin is a strong antihypertensive agent that has a hemodynamic profile similar to that of arteriolar dilators. Trequinsin can block platelet aggregation and also inhibit tissue factor expression in human endothelial cells,.
Phosphodiesterase III inhibitor.

Discover Bioactive Small Molecules for Cyclic Nucleotides

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.
