Sumanirole (PNU-95,666) is a highly
selective D2 receptor full agonist, the first of its kind to be discovered.
It was developed for the treatment of
Parkinson's disease and
restless leg syndrome. While it has never been approved for medical use
it is a highly valuable tool compound for basic research to identify neurobiological mechanisms that are based on a dopamine D
2-linked (vs. D
1-, D
3-, D
4-, and D
5-linked) mechanism of action.
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”.
