MLN3126 is an orally active and potent CCR9 antagonist. MLN3126 inhibits CCL25-induced calcium mobilization and chemotaxis of mouse primary thymocytes, wiht an IC50 value of 6.3 nM for calcium influx[1].
MLN3126 inhibits CCL25-induced calcium mobilization with an IC50 value of 6.3 nM in CCR9 expressing cells[1].
MLN3126 inhibits the binding of biotinylated CCL25 to CCR9 with an IC50 of 14.2 nM[1].
MLN3126 (2.5% w/w; p.o.) decreases colonic level of IFN-γ, largely produced by T cells[1].
MLN3126 (0.05, 0.25 and 1% (w/w); p.o.) has the potential activity for alleviating inflammatory bowel disease (IBD)[1].
