Function[PDE2A_HUMAN] Cyclic nucleotide phosphodiesterase with a dual-specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological processes.[1] [2] Publication Abstract from PubMedA series of potent and selective [1,2,4]triazolo[1,5-a]pyrimidine PDE2a inhibitors is reported.
