PS372424

Biological Activity

[Description]:

PS372424, a three amino-acid fragment of CXCL10, is a specific human CXCR3 agonist with anti-inflammatory activity, which inhibits the binding of CXCR3 ligand CXCL10 to CXCR3 receptor with IC50 of 42 nM[1][2][3].

[Target]

CXCR3

[In Vitro]

PS372424 (10-200 nM; 30 min) causes a concentration-dependent phosphorylation of CCR5 on CXCR3+ T cells not in CXCR3- T cells[1]. Western Blot Analysis[1] Cell Line: CXCR3+ T cells and CXCR3- T cells Concentration: 10, 50, 100, or 200 nM Incubation Time: 30 minutes Result: Caused a concentration-dependent phosphorylation of CCR5 on CXCR3+ T cells. Did not result in phosphorylation of CCR5 on CXCR3- T cells.
