Bay 60-7550 is primarily used in research settings as a potent and selective inhibitor of phosphodiesterase 2 (PDE2). It is widely applied in neuroscience studies to investigate the role of PDE2 in cognitive functions, such as memory and learning. Researchers utilize it to explore its potential in enhancing synaptic plasticity and improving cognitive performance in preclinical models. Additionally, Bay 60-7550 is employed in studies focusing on psychiatric and neurological disorders, including anxiety, depression, and Alzheimer's disease, to understand the therapeutic implications of PDE2 modulation. Its application extends to cardiovascular research, where it is used to study the effects of PDE2 inhibition on heart function and vascular tone. Overall, Bay 60-7550 serves as a valuable tool for elucidating the biological pathways and therapeutic potential of PDE2 inhibition.
