PNU-177864 is a selective antagonist of D3 receptor. Compound was considered as a drug candidate for the chronic treatment of schizophrenia, but severe myopathy was found in skeletal muscles of rats during the initial safety evaluation of PNU-177864. Myopathy was associated with phospholipidosis in numerous tissues.

Sample Use Guides

In preclinical toxicology studies phospholipidosis was observed when PNU-177864 was administered to rats orally at doses >= 80 mg/kg/day or to dogs at doses >= 32 mg/kg/day.
Route of Administration: Oral
Binding assay was performed using over-expressing human D3 CHO cell lines. [3H]-7-OH-DPAT (Kd for D3 1.4 nM) was used a radioligand. Membrane radioligand levels were determined by liquid scintillation counting. Non-specific binding was determined by radioligand binding in the presence of a saturating concentration of haloperidol. PNU-177864 binds to D3 receptors with Ki of 38.2 nM.
