Background:

PK14105 is a biological evaluation as a potential radioligand for PET studies of PBBS receptors.in vivo binding experiments, in which PK 14105 was injected into rats with unilaterallylesioned striata, demonstrate that PK 14105 rapidly crosses the blood-brain-barrier and that thereis a marked retention of radioactivity in the lesioned striatum not seen in the unlesioned striatum or cerebellar vermis[1]It can also inhibit receptor ligands, calcium channel ligands and co-transporter in all salivary glands.
