Sumanirole (PNU-95,666) is a highly selective D2 receptor full agonist, the first of its kind to be discovered.[1][2][3] It was developed for the treatment of Parkinson's disease and restless leg syndrome. While it has never been approved for medical use [4][5] it is a highly valuable tool compound for basic research to identify neurobiological mechanisms that are based on a dopamine D2-linked (vs. D1, D3, D4, and D5-linked) mechanism of action.[3]
In 2004, Pfizer announced the end of their clinical development program for sumanirole, citing “recent studies that failed to sufficiently distinguish sumanirole from currently available therapies”.[6]
