GW 766994 is an antagonist of chemokine (C-C motif) receptor 3 (CCR3) with a K_i value of 13.8 nM in an assay of eosinophil chemotaxis induced by chemokine (C-C motif) ligand 11 (CCL11). It decreases CCL11-induced cyclin-dependent kinase 5 (Cdk5) and tau phosphorylation and production of amyloid β (1-42) (Aβ42) in isolated mouse hippocampal neurons when used at a concentration of 10 μM.

GW 766994 (GW 994) is an orally active and specific chemokine receptor-3 (CCR3) antagonist. GW 766994 has the potential for asthma and eosinophilic bronchitis research[1][2].
