Rolipram was a selective phosphodiesterase-4 inhibitor discovered and developed by Schering AG as a potential antidepressant drug in the early 1990s.[2] It served as a prototype molecule for several companies' drug discovery and development efforts.[3]:668ff Rolipram was discontinued after clinical trials showed that its therapeutic window was too narrow; it could not be dosed at high enough levels to be effective without causing significant gastrointestinal side effects.[3]:668

It continues to be used in research as a well-characterized PDE4 inhibitor.[3]:669 It has been used in studies to understand whether PDE4 inhibition could be useful in autoimmune diseases,[4] Alzheimer's disease,[5] cognitive enhancement,[6] spinal cord injury,[7] and respiratory diseases like asthma and COPD.[8]
