Product Introduction

Bioactivity
Description
Gefapixant citrate (AF-219 citrate) is an orally available, highly potent P2X3 receptor antagonist with antitussive properties that inhibits hP2X2/3. It can be used to study chronic cough.
In vitro
Gefapixant citrate did not inhibit any receptor that did not contain a P2X3 subunit, and its IC50 values exceeded 10,000 nM on recombinant hP2X1, hP2X2, hP2X4, rP2X5, and hP2X7 channels. [1]
In vivo
In a rat model of knee osteoarthritis, Gefapixant citrate (administered orally twice daily for 7 days) was able to attenuate the abnormal response on the weight-loading side and completely reversed the significant nociceptive hypersensitivity at the two higher doses (20 mg/kg and 60 mg/kg) (the model was established by intra-articular injections of monoiodoacetic acid and was observed for 14 days post-injection).

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
