Mechanism of Action

Targets/IC₅₀/Ki	Dopamine receptor
In vitro	Paliperidone significantly increases the intracellular accumulation of Rh123 and DOX in a concentration-dependent manner. This compound works finely at low concentrations (10 and 50 μM) against Aβ(25-35) and MPP(+) and solely protects SH-SY5Y from hydrogen peroxide. It completely diminishes cell reduction induced by different stressors, regardless of their dosages. This chemical is demonstrated with higher oxidative stress-scavenging properties than other APDs in several aspects, such as generated bulk glutathione, low HNE, and protein carbonyl productions. It enhances dopamine toxicity at the highest dose and is the only AP that significantly increases cell viability (8.1%) compared with cells treated with dopamine alone.
In vivo	Paliperidone normalizes prefrontal cortical basal extracellular glutamate in rats. This compound also prevents the acute MK-801-induced increase in extracellular glutamate in rats. When coadministered with Escitalopram, it restores the suppression of the NE neuronal firing rate (n = 5 rats) and the percentage of neurons exhibiting burst firing. It results in a dose-dependent decrease in bite and attack behaviors with an effective dose. This chemical results in the maximal reduction in aggressive behavior.
