BMS-570520 is an orally bioavailable CCR3 antagonist with an IC50 of 1.9 nM against hCCR3 and an IC50 of 1300 nM against hCYP2D6. BMS-570520 inhibits CYP2D6, but shows low activity against off-target G protein-coupled receptors, biogenic amine transporters, and the hERG potassium channel. BMS-570520 regulates chemotaxis, calcium mobilization, and anti-inflammatory pathways. BMS-570520 can be used in research related to asthma, allergic rhinitis, and contact dermatitis[1].
