Microsomal prostaglandin E2 synthase-1 (mPGES-1) is a novel therapeutic target for the treatment of inflammation and pain. During the course of studies aimed at the identification of a suitable mPGES-1 inhibitor for clinical development, a need arose for preparing enantiomerically enriched amino alcohols (S,S)-2 and (S,S)-3. Described herein, a concise synthesis of (S,S)-2 and (S,S)-3 has been developed wherein both amino alcohols are derived from a commercially available, low-cost starting material.

Starting with our previously described20 class of CC chemokine receptor-3 (CCR3) antagonist, we improved the potency by replacing the phenyl linker of 1 with a cyclohexyl linker and by replacing the 4-benzylpiperidine with a 3-benzylpiperidine. The resulting compound, 32, is a potent and selective antagonist of CCR3. SAR studies showed that the 3-acetylphenyl urea of 32 could be replaced with heterocyclic ureas or heterocyclic-substituted phenyl ureas and still maintain the potency (inhibition of eotaxin-induced chemotaxis) of this class of compounds in the low-picomolar range (IC50 = 10-60 pM), representing some of the most potent CCR3 antagonists reported to date. The potency of 32 for mouse CCR3 (chemotaxis IC50 = 41 nM) and its oral bioavailability in mice (20% F) were adequate to assess the efficacy in animal models of allergic airway inflammation. Oral administration of 32 reduced eosinophil recruitment into the lungs in a dose-dependent manner in these animal models. On the basis of its overall potency, selectivity, efficacy, and safety profile, the benzenesulfonate salt of 32, designated DPC168, entered phase I clinical trials.
