| In Vitro | Pimozide is a dopamine receptor antagonist, with Kis of 1.4 nM, 2.5 nM and 588 nM for dopamine D2, D3 and D1 receptors, respectively; also has affinity at α1-adrenoceptor and 5-HT1A, with Kis of 39 nM and 310 nM, respectively[1]. Pimozide acts as an inhibitor of STAT3. Pimozide (0-15 μM) shows inhibitory of the proliferation of U2OS cells, with IC50 value at 24, 48, and 72 h of 22.16 ± 2.54, 17.49 ± 1.14 and 13.78 ± 0.34 μM, respectively. Pimozide (10 μM) inhibits the colony- and sphere-forming abilities of osteosarcoma cells. Pimozide (15 μM) induces G0/G1 phase cell cycle arrest, suppresses the extracellular signal-regulated kinase (Erk) signaling to inhibit cell viability, and produces ROS generation through inhibiting antioxidant enzyme gene catalase expression in osteosarcoma cells[2]. Pimozide acts as an inhibitor of STAT5. Pimozide reduces the expression of endogenous STAT5 target genes, and decreases STAT5 tyrosine phosphorylation[3]. |
| Cell Assay | Cell proliferation is assessed by WST-8 colorimetric assay. Human osteosarcoma cells are plated in 96-well plates with 2,500 cells per well and exposed to the treatment of different concentrations of pimozide for various time intervals (24 h, 48 h, and 72 h). The WST-8 solution is added to each well after indicated time. After incubated at 37°C for another 4 hours, the absorbance ismeasured at 450 nm using a multi-well plate reader[2]. |
