Abstract:
:Bipiperidine amide 1 has been identified as a CC chemokine receptor 3 (CCR3) antagonist. Optimization of its structure-activity relationship has resulted in the identification of cis (R,R)-4-[(3,4-dichlorophenyl)methyl]-3-hydroxymethyl-1'(6-quinolinylcarbonyl)-1,4'-bipiperidine 14n, which exhibits potent receptor affinity and inhibition of both calcium flux and eosinophil chemotaxis.
