| Bioactivity | YM-90709 is a novel IL-5 inhibitor which selectively blocks the binding of IL-5 to the IL-5 receptor (IL-5R).YM-90709 potently inhibits the binding of [125I]-IL-5 to IL-5R on human peripheral eosinophils and eosinophilic HL-60 clone 15 cells with IC50 values of 1.0 and 0.57 μM[1]. | ||||||||||||
| Invitro | YM-90709 (0-100 μM;1 hour) inhibits the binding of [125I]-IL-5 to IL-5R on human peripheral eosinophils and eosinophilic HL-60 clone 15 cells[1]. YM-90709 (0-100 μM; 96 hour; Eosinophilic HL-60 clone 15 cells) affects IL-5 and GM-CSF and prolonged the survival time of eosinophils[1]. YM-90709 (0-100 μM; 5 min; Eosinophilic HL-60 clone 15 cells) inhibits IL-5-induced, but not GM-CSF-induced, eosinophil survival as well as the tyrosine phosphorylation of Janus kinase 2[2].

| In Vivo | YM-90709 (0.01-10 mg/kg; intravenous injection, 72 hours, Inbred female Brown-Norway (BN) rats) results in the inhibition of antigen-induced infiltration of eosinophils and lymphocytes, but not neutrophils or monocytes, into the bronchoalveolar lavage fluid (BALF) of Brown-Norway (BN) rats[2].
