Additional Information

Novel phosphodiesterase inhibitors are being studied to treat Alzheimer’s disease. Phosphodiesterases (PDEs) hydrolyze cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). They are prominently expressed in the brain, and thus are targeted in Alzheimer’s disease treatments to regulate cAMP and cGMP concentrations (which can lead to a downstream control of various proteins involved in cognitive maintenance). PDE inhibitors have been shown to effect cognitive improvement in dealing with common dementia symptoms, including progressive memory loss, a decline in language skills, and some other neurodegenerative disorders, in comparison with the available treatments of acetylcholine inhibitors, which do not reverse the progression of Alzheimer’s.
