Spiperone interacts with various monoamine receptors.536

Additionally, spiperone was identified by compound screening to be an activator of Ca2+ activated Cl− channels (CaCCs), thus a potential target for therapy of cystic fibrosis.7

Chemistry

Derivatives

N-Methylspiperone (NMSP) is a derivative of spiperone that is used to study the dopamine and serotonin neurotransmitter system. Labeled with the radioisotope carbon-11, it can be used for positron emission tomography.8
