SB-328437

SB-328437 is a potent, selective non-peptide CCR3 antagonist with an IC50 of 4.5 nM. SB-328437 can inhibit eosinophil migration induced by eotaxin, eotaxin-2, and monocyte chemotactic protein-4. In addition, SB-328437 can sensitize 5-FU -resistant gastric cancer cells. SB-328437 can also reduce the recruitment of neutrophils to the lungs and pulmonary inflammation during acute inflammation. SB-328437 can be used in the research of inflammation-related diseases[1][2][3].
