Paliperidone

The main chemicals used in this study, including FGAs (chlorpromazine, chlorprothixene, clothiapine, droperidol, flupentixol, fluphenazine, haloperidol, levomepromazine, loxapine, pimozide, prochlorperazine, sulpiride, thioridazine, and trifluoperazine) and SGAs (amisulpride, aripiprazole, brexpiprazole, clozapine, lurasidone, olanzapine, paliperidone, quetiapine, risperidone, ziprasidone, and zotepine) were acquired from Sigma-Aldrich (St. Louis, Missouri, USA) and were of highest purity grade. Before usage, the compounds were dissolved in dimethyl sulfoxide (DMSO) at the proper concentrations. Human hepatoma HepaRG™ cells were purchased from Thermo Fisher Scientific (Waltham, Massachusetts, USA). For 2 weeks, frozen cells were defrosted and kept alive in Williams’ E medium (Sigma-Aldrich, St. Louis, Missouri, USA) with 10% FetalClone™ II serum (HycloneTM, GE Healthcare, Chicago, Illinois, USA), 1 × L-glutamine, 5 μg/mL human insulin, and 50 μM hydrocortisone hemisuccinate without antibiotics as supplements. To produce differentiated hepatocyte-like features, the medium was then changed to the aforementioned medium plus 2% DMSO for an additional 2 weeks. Cells were grown at 37°C in a humidified 5% CO₂ environment. P-nitrophenylphosphate (PNPP) was used in an acid phosphatase (ACP) experiment to measure cell viability (29 (link)).
