About PDE1 Inhibitors

PDE1 inhibitors are unique, orally available, investigational drug candidates being developed for the treatment of cognitive impairments accompanying schizophrenia, Alzheimer's disease and other neuropsychiatric disorders and neurological diseases and may also treat patients with Attention Deficit Hyperactivity Disorder and Parkinson's disease. These compounds may also have the potential to improve motor dysfunction associated with these conditions and may also have the potential to treat patients with multiple sclerosis and other autoimmune diseases and pulmonary arterial hypertension. These compounds are very selective for the PDE1 subfamily relative to other PDE subfamilies. They have no known significant off target activities at other enzymes, receptors or ion channels.
