AZD-4818, a chemokine CCR1 antagonist: WO2008103126 and WO2009011653

Abstract

The applications WO2008103126 and WO2009011653, respectively, claim: i) Combinations of a spirocyclic piperidine chemokine CCR1 antagonist with a corticosteroid, and their use for the treatment of asthma and chronic obstructive pulmonary disease. ii) Processes for the preparation of a spirocyclic piperidine derivative, a chemokine CCR1 antagonist. These applications point to the preferred compound being a development compound. The evidence for this compound being AZD-4818, a chemokine CCR1 antagonist that was in Phase II development for the treatment of chronic obstructive pulmonary disease, is reviewed in the light of these and earlier patents relating to it.
