Introduction: Vilazodone is a kind of serotonergic antidepressant developed by Merck KGaA Company. It is a novel compound with high affinity and selectivity for the 5-hydroxytrptamine (5-HT) transporter and 5-HT (1A) receptors. It is indicated for the treatment of major depressive disorder (MDD). It is can be used as an alternative drugs for other kind of antidepressant classes drugs that can’t be tolerated by patients. As a selective serotonin reuptake inhibitor, vilazodone can prevent the serotonin from re-entering into cell bodies, therefore making it remain longer inside the synapse. Moreover, it has a high selectivity for the serotonin-1A receptor, taking effect as a partial agonist that can simulate the production of serotonin. These effects result in increased serotonin in the synaptic cleft. This effect is related to the antidepressant effect of vilazodone in vivo. View more+

8.6 体外研究

Vilazodone shows an IC 50 of 0.2 nM at the human 5-HT 1 A receptor and 0.5 nM for the SERT. Vilazodone preferentially binds to the high agonist affinity state of human 5-HT 1 A receptors, and it displays high affinity (pK i ≥9.3) for human recombinant and rat, guinea pig, mouse, and marmoset native tissue 5-HT 1A receptors.Vilazodone acts as a high efficacy partial agonist at 5-HT 1 A receptors. In [ 35 S]GTPγS binding studies in Sf9 cells expressing h5-HT 1 A receptors, a single concentration of Vilazodone (100nM) increases basal binding by approximately 70% of that produced by the full 5-HT 1 A receptor agonist, 8‐OH‐PIPAT. In [ 35 S]GTPγS binding studies in rat hippocampal membranes, Vilazodone acts as a potent 5‐HT 1A receptor partial agonist with a pEC 50 of 8.1 and an intrinsic activity of 0.61. Vilazodone acts as a potent 5‐HT reuptake inhibitor in rat and guinea pig cortex. In LLCPK cells expressing human SERT, whereby vilazodone inhibits [ 3 H]5‐HT uptake with a pIC 50 of 8.8.

8.7 体内研究

Vilazodone (intraperitoneal injection; 3 mg/kg ; single dose) produces increases in extracellular levels of 5‐HT in both the frontal cortex (FC) and ventral hippocampus (vHipp) of rats in vivo microdialysis studies. Maximum increases are observed at 3 mg/kg and reaches 527% and 558% of preinjection baseline values in the FC and vHipp, respectively. Vilazodone (oral gavage ;55 mg/kg ; single dose) inhibits stress‐induced vocalizations in the rat ultrasonic vocalizations test at 120 and 210 min post dose.

8.8 Description
In January 2011, the U.S. FDA approved vilazodone for the treatment of major depressive disorder (MDD). Vilazodone is a novel antidepressant agent that combines potent serotonin reuptake inhibition (IC50=0.2 nM) with high affinity for 5-HT1A receptors (IC50=0.5 nM)and partial 5-HT1A receptor agonist functional activity. Vilazodone has good selectivity over other monoamine receptors and is efficacious in preclinical models of depression in rats and mice. Vilazodone is an indolylbutylpiperazine derivative that has been prepared by coupling of an indolylbutyl chloride or tosylate with 5-(piperazin-1-yl)benzofuran-2- carboxamide or the corresponding ester. The cyanoindole portion of vilazodone is important for conferring high affinity for both the serotonin transporter and the 5-HT1A receptor. Para-substitution on the phenyl group attached to the piperidine moiety reduces affinity for dopamine receptors, while the carboxamide group provides improved pharmacokinetic properties.
