Chemical Structure

Biological activities

Bay 60-7550 is a potent and selective PDE2 inhibitor. Bay 60-7550 inhibits the activity of PDE2 purified from bovine heart and human recombinant PDE2 with IC50s of 2.0 and 4.7 nM, respectively.[1] BAY 60-7550 improves memory functions by enhancing neural plasticity. In cell culture and slice models, BAY 60-7550 increases neuronal cGMP levels in response to a stimulus of the NO/cGMP pathway.[2] BAY 60-7550 (10 µM) significantly reduces the effect of SNAP on the ISO-induced cAMP response in the PKA-RII compartment.[3] Furthermore, Bay 60-7550 enhances long-term potentiation of synaptic transmission without altering basal synaptic transmission.[1] In vivo, oral administration of BAY 60-7550 improves memory consolidation in rodent models of learning and memory.[2] Bay 60-7550 (3mg/kg i.p.) significantly attenuates the BSO-induced decrease in total antioxidant capacity and increase in the expression of NADPH oxidase subunits, both in hypothalamus and amygdala.[4]

Protocols

In vitro, Bay 60-7550 is dissolved in DMSO.[1]
