Abstact

Crystallography-driven optimisation of a lead derived from similarity searching of the GSK compound collection resulted in the discovery of a series of quinoline derivatives that were highly potent and selective inhibitors of PDE4 with a good pharmacokinetic profile in the rat. Quinolines 43 and 48 have potential as oral medicines for the treatment of COPD.
