| Description | Levomepromazine (Methotrimeprazine) is an orally active aliphatic phenothiazine antipsychotic compound and a Ca2+ release inducer, exhibiting antiviral, anti-inflammatory, neuroprotective, analgesic, and anti-nociceptive activities. Levomepromazine inhibits dopaminergic, cholinergic, serotoninergic, and histaminergic receptors, and is used for research in neurodegenerative diseases. |
| In vitro | Levomepromazine(0.01-200 μM,72h) increased the CYP3A4 activity of HU1832 to 152% at 2.5 μM. [1] Levomepromazine (10 μM, 24 h) reduced Japanese encephalitis virus (JEV) -induced Neuro2a cell death, decreased JEV RNA levels and viral titers, and significantly inhibited JEV protein translation/replication complex formation and ROS production. Levomepromazine (10 μM, 24 h) reduces inflammation in microglia by inducing autophagy. [2] |
| In vivo | Levomepromazine (5-20 mg/kg; Intraperitoneal injection) has analgesic, sedative and anti-injurious effects in mice [4]. |
