Mechanism of Action

Targets/IC₅₀/Ki	D2 receptor 0.7 nM 5-HT2 1.2 nM 5-HT2B 1.2 nM D3 receptor 1.5 nM D4 receptor 9 nM
In vitro	Cabergoline prevents the oxidative stress-induced cell death of cultured cortical neurons via a D2 receptor-mediated mechanism. This compound suppresses the activation of ERK signaling, which might have a role in the neuroprotection. It significantly represses extracellular glutamate accumulation triggered by oxidative stress, and increases the expression of glutamate transporters including EAAC1, which is known to be involved in the clearance of extracellular glutamate.
In vivo	Cabergoline has a long elimination half-life (63 to 109 h). An in vivo study of neuronal damage induced by intracerebroventricular (icv) injection of 6-OHDA, a neurotoxic compound that selectively damages dopaminergic neurons in male ICR mice, demonstrates that intraperitoneal (ip) administration of this compound for 7 days prevented nigrostriatal region dopaminergic neurons from cell death. It also protects SH-SY5Y neuroblastoma from cell death by oxygen-glucose deprivation even when this chemical is administered after the induction of cell death. This compound increases hippocampal brain-derived neurotrophic factor (BDNF, an important regulator in the synaptic plasticity) and exerts an antidepressant effect in rats.
