A new series of quinazolines that function as CCR4 antagonists were discovered during the screening of our corporate compound libraries. Subsequent compound optimization elucidated the structure-activity relationships and led the identification of 2-(1,4′-bipiperidine-1′-yl)-N-cycloheptyl-6,7-dimethoxyquinazolin-4-amine 14a, which showed potent inhibition in the [35S]GTPγS-binding assay (IC50 = 18 nM). This compound also inhibited the chemotaxis of human and mouse CCR4-expressing cells (IC50 = 140 nM, 39 nM).
