Cat. No.: HY-101588A
Handling Instructions

Molarity Calculator

Gefapixant citrate is an orally active and potent purinergic P2X3 receptor (P2X3R) antagonist, with IC50 values of ~30 nM versus recombinant hP2X3 homotrimers and 100-250 nM at hP2X2/3 heterotrimeric receptors. Gefapixant citrate can be used for the research of chronic cough and knee osteoarthritis.

Description

Gefapixant citrate is an orally active and potent purinergic P2X3 receptor (P2X3R) antagonist, with IC50 values of ~30 nM versus recombinant hP2X3 homotrimers and 100-250 nM at hP2X2/3 heterotrimeric receptors. Gefapixant citrate can be used for the research of chronic cough and knee osteoarthritis[1][2][3].

IC50 & Target

P2X3 Receptor

 

In Vitro

Gefapixant citrate displays no inhibitory impact on any non-P2X3 subunit containing receptors (IC50 values >10,000 nM at recombinant homotrimeric hP2X1, hP2X2, hP2X4, rP2X5 and hP2X7 channels)[1].

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.
