YM-344484
YM-344484 is an orally active dual antagonist of chemokine CCR3 receptor and histamine histamine H1 receptor. YM-344484 inhibits ligand-induced Ca2+ influx, chemotaxis of CCR3-expressing cells, histamine-induced Ca2+ influx, increased vascular permeability and eosinophil accumulation. YM-344484 suppresses vascular permeability and inhibits eosinophil infiltration in a mouse asthma model. YM-344484 can be used in research related to asthma, allergic rhinitis and atopic dermatitis.

YM-344484 potently inhibits CCR3 ligand-induced calcium influx in B300-19 cells expressing human CCR3, with its Kβ values ranging from 0.69 nM to 2.5 nM depending on the ligand[1].
YM-344484 inhibits CCL11-induced calcium influx in mouse CCR3-expressing cells, with a Kβ value of 88 nM[1].
YM-344484 inhibits histamine H1 receptor-mediated calcium influx in PC3 cells, with a Kβ value of 47 nM[1].
YM-344484 (10 μM) exhibits only weak inhibitory activity against serotonin 5-HT2A receptor-mediated calcium influx in C6 cells, with an inhibition rate of merely 25%[1].
YM-344484 potently inhibits CCR3 ligand-induced chemotaxis in human CCR3-expressing B300-19 cells, with its IC50 values ranging from 2.0 nM to 8.0 nM depending on the ligand[1].
YM-344484 inhibits the release of eosinophil-derived neurotoxin from human peripheral blood eosinophils induced by CCL11, with an IC50 value of 19 nM[1].
