Description

Vofopitant is potent tachykinin NK1 receptor antagonist, with pKis of 10.6, 9.5, and 9.8 for human, rat and ferret NK1 receptor, respectively.

IC50 & Target

pKi: 10.6 (Human NK1 receptor), 9.5 (Rat NK1 receptor), 9.8 (Ferret NK1 receptor)[1]
In Vitro

Vofopitant is potent tachykinin NK1 receptor antagonist, with pKis of 10.6, 9.5, and 9.8 for human, rat and ferret NK1 receptor, respectively. Vofopitant less potently inhibits rat 5-HT1A, bovine 5-HT1D, rat 5-HT2A, rat Histamine H1, guinea-pig Histamine H2 and rat Ca2+ channel, with pKis of 6.3, 6.6, 6.5, 6.5, 6.6, and 5.6, respectively. Vofopitant shows negligible affinity at NK2 and NK3, with pIC50 of <5.0[1]. GR205171 (300 µM) potentiates the effects of paroxetine on cortical [5-HT]ext, and inhibits paroxetine-induced increase in [5-HT]ext in the dorsal raphe nucleus[3].

In Vivo

Vofopitant (GR205171, 30 mg/kg, s.c.) increases the number of choices of the 25-s delayed reward in a T-maze[2]. Vofopitant (GR205171, 30 mg/kg, i.p.) increases the extracellular 5-HT levels in the frontal cortex of paroxetine-treated wild-type mice, rather than in wild-type mice and paroxetine-treated NK1 receptor knockout mice[3].

Kinase Assay
[1]

Tachykinin NK1 receptor binding assays are carried out in an assay volume of 200 μL, consisting of 50 μL of wash buffer (containing HEPES (50 mM) and MnC12 (3 mM), pH 7.4) or test compound (Vofopitant), 100 μL membrane suspension (3-5 μg of protein) in HEPES assay buffer (composition as above, but containing bacitracin, 80 μg/mL], leupeptin, 8 μg/mL], phosphoramidon, 2 μM and bovine serum albumin, 0.04%) and 50 μL of [3H]substance P (0.7-1.0 nM final concentration). The incubation is carried out at room temperature for 40 min. Non-specific binding is defined by the addition of CP-99,994 (1 μM)[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration
[3]

Effect of NK1 receptor antagonists administered i.p. on cortical [5-HT]ext of wild-type mice. Following collection of four baseline dialysate samples, freely moving wild-type mice are administered with either the vehicle or various NK1 receptor antagonists, Vofopitant (30 mg/kg; i.p.) or L733060 (40 mg/kg; i.p.). Dialysate samples are collected for a 0-120 min post-treatment period[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
