The SAR features have been further explored for (2-benzhydryl-4-phenyl-thiazol-5-yl) acetic acids as CRTH2 (chemoattractant receptor-homologous molecule expressed on Th2 cells) antagonists. The introduction of a nitrogen or a methyl substituent in the benzhydrylic position offer two alternative drugable scaffolds attractive for unsymmetrically substituted derivatives. An imidazole analogue lacks activity due to formation of a favored coplanar intramolecular hydrogen bond. The pyrimidine derivative 18 represents a potent and selective compound that will be subject to continued investigations. (C) 2010 Elsevier Ltd. All rights reserved.
