Biochem/physiol Actions

BAY 60-7550 is an orally active, potent and selective cGMP-dependent phosphodiesterase PDE2 (PDE2A) inhibitor (human/bovine PDE2 IC50 = 4.7/2.0 nM; bovine PDE1 IC50 = 108 nM, human PDE5/5A/10A/4B IC50 = 240/580/704/940/1830 nM, human PDE3B/7B/8A/9A/11A IC50 >4 μM) with little activity (IC50 >10 μM) toward acetylcholinesterase, mAO-A/B, adenosine deaminase, and many receptor subtypes tested. Bay 60-7550 effectively upregulates cGMP and cAMP level in cultured rat and murine neurons (1 nM-1 μM) exposed to guanylyl cyclase (GC) or adenylyl cyclase (AC) stimulator (1 μM Bay 41-8543 or 2 μM forskolin), respectively, as well as exhibits learning and memory-improving efficacy in rats (0.6-3 mg/kg p.o.) and mice (0.3-1 mg/kg p.o.) in vivo.

Phosphodiesterase inhibitors possess anti-inflammatory properties. In addition, some studies report that phosphodiesterase 2A (PDE2A) are highly expressed in the dorsal horn of the spinal cord. The present study aimed to investigate whether intrathecal administration of Bay 60-7550, a specific PDE2A

Hypertension is associated with impaired nitric oxide (NO)-cyclic nucleotide (CN)-coupled intracellular calcium (Ca(2+)) homeostasis that enhances cardiac sympathetic neurotransmission. Because neuronal membrane Ca(2+) currents are reduced by NO-activated S-nitrosylation, we tested whether CNs affect membrane channel conductance directly in neurons

In patients after acute myocardial infarction (AMI), the initial extent of necrosis and inflammation determine clinical outcome. One early event in AMI is the increased cardiac expression of atrial natriuretic peptide (NP) and B-type NP, with their plasma levels correlating

Phosphodiesterase 2 is a dual substrate esterase, which has the unique property to be stimulated by cGMP, but primarily hydrolyzes cAMP. Myocardial phosphodiesterase 2 is upregulated in human heart failure, but its role in the heart is unknown. To explore

Cognitive and affective impairments are the most characterized consequences following cerebral ischemia. BAY 60-7550, a selective phosphodiesterase type 2 inhibitor (PDE2-I), presents memory-enhancing and anxiolytic-like properties. The behavioral effects of BAY 60-7550 have been associated with its ability to prevent
