Biological Activity

BMS-639623 is a potent, selective and orally bioavailable CCR3 antagonist with binding IC50 of 0.3 nM and chemotaxis IC50 of 0.04 nM.
BMS-639623 is selective against other 7TM receptors and ion channels.
BMS-639623 also shows activity in eotaxin-stimulated calcium flux in eosinophils with IC50 of 0.87 nM.
BMS-639623 shows poor binding and chemotaxis inhibition potency in the mouse (IC50=31, 870 nM, respectively).
BMS-639623 inhibits cyno eosinophil chemotaxis with IC50 of 0.15 nM.
BMS-639623 (5 mg/kg b.i.d.) reduces the allergen-dependent eosinophilia by 65%, 78%, and 82% in cyno study.
