BMS-570520 is a мощный, селективный CCR3 антагонист с IC50 of 1.9 nM, inhibits eotaxin-induced chemotaxis с IC50 of 0.068 nM.BMS-570520 displays reduced inhibition on CYP2D6 (IC50=1300 nM) compared with DPC168 (IC50=30 nM), also possesses >100-fold selectivity over 5-HT2a, DAT and NET.BMS-570520 showed good activity in murine models of CCR3 antagonism and greater in vitro potency and in vivo in the mouse intranasal eotaxin challenge mode.
