Vofopitant
Based on 1 Customer Validation
Vofopitant (GR 205171A) is a blood-brain barrier-permeable NK1 receptor inhibitor with a pKi of 9.02 in mice. Vofopitant blocks vomiting-related responses and inhibits pseudoptyalism. Vofopitant exerts anxiolytic effects, regulates 5-HT receptor function and increases central 5-HT release. Vofopitant improves hyperarousal symptoms of post-traumatic stress disorder. Vofopitant can be used in research related to depression, anxiety, vomiting and postoperative nausea and vomiting.

Vofopitant (GR 205171) (10 pM-1 mM; 60 min) potently inhibits [3H]-SP binding to NK1 receptors in mouse cerebral cortex homogenates with a pKi of 9.02[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Vofopitant (GR-205171) (50 µg/kg; i.v.; single dose) abolishes fictive retching and emesis-associated antral contractility enhancement, reduces emesis-related hypersalivation and parasympathetic nerve activity, but does not affect gastric corpus relaxation, vagosalivary reflex-mediated salivation, or linguosalivary reflex responses in dogs[2].
Vofopitant (GR 205171) (10 mg/kg; s.c.; single dose) does not alter DRN serotonergic neuron firing or 5-HT1A autoreceptor sensitivity in male C57BL/6J mice[4].
Vofopitant (10 mg/kg/day; s.c.; continuous delivery; 21 days) reduces the potency of Ipsapirone (HY-19686) to inhibit DRN serotonergic neuron firing by ~1.5-fold, indicating functional desensitization of 5-HT1A autoreceptors in male C57BL/6J mice[4].
Vofopitant (10 mg/kg/day; s.c.; continuous delivery; 21 days) reduces the potency and maximal effect of 5-CT to stimulate [35S]GTP-γ-S binding in the DRN, indicating impaired G-protein coupling of desensitized 5-HT1A autoreceptors in male C57BL/6J mice[4].
Vofopitant (10 mg/kg/day; s.c.; continuous delivery; 21 days) significantly increases basal extracellular 5-HT levels in the DRN and potentiates Paroxetine (HY-122272)-induced cortical 5-HT overflow in male C57BL/6J mice[4].

Animal Model:CD-1 mice (20-26 g)[1]
-
Dosage:3 mg/kg; 10 mg/kg; 30 mg/kg
-
Administration:i.p.; single dose
-
Result:Did not reduce immobility time obviously at 3 mg/kg.
Exerted mild and non-significant reduction at 10 mg/kg.
Reduced immobility time significantly at 30 mg/kg.
Showed no notable changes in cortical monoamine levels at 30 mg/kg within 300 minutes.
-
Animal Model:C57BL/6J (male, 8-10 weeks old, 20-25 g)[5]
-
Dosage:10 mg/kg
-
Administration:s.c.; single dose
-
Result:Did not change firing frequency and pattern of DRN serotonergic neurons.
Exhibited comparable inhibitory potency of ipsapirone on neuronal firing between treatment and control groups.
Produced full inhibition at 100 nM ipsapirone in both groups.

Animal Model:C57BL/6J (male, 8-10 weeks old, 20-25 g)[5]
-
Dosage:10 mg/kg/day
-
Administration:s.c.; continuous delivery; 21 days
-
Result:Did not change basal firing rate of DRN serotonergic neurons.
Decreased ipsapirone’s inhibitory potency on neuronal firing and raised its concentration for full inhibition.
Displayed similar basal [35S]GTP-γ-S labelling in the DRN between groups.
Weakened 5-CT-induced [35S]GTP-γ-S binding with a right-shifted curve and lower maximal response.
Exerted no influence on basal extracellular 5-HT in the frontal cortex but elevated basal 5-HT levels in the DRN.
Enhanced paroxetine-triggered 5-HT elevation in both cortex and DRN of treated mice.
