PS372424 

PS372424, a three amino-acid fragment of CXCL10, is a specific human CXCR3 agonist with anti-inflammatory activity. PS372424 prevents human T-cell migration in a humanized model of arthritic inflammation^[1][2].

PS372424 (100 ng/mL) increases p-Erk1 and p-Erk2 in U87-CXCR3-A cells after 5 min of stimulation^[1].
PS372424 (10-200 nM; 30 min) causes a concentration-dependent phosphorylation of CCR5 on CXCR3⁺ T cells not in CXCR3^- T cells^[2].
PS372424 competes for binding of radiolabeled CXCL10 to membranes prepared from HEK293/CXCR3 Gqi5 cells with an IC₅₀ of 42±21 nM^[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
