Discovery of disubstituted phenanthrene imidazoles as potent, selective and orally active mPGES-1 inhibitors
摘要:
Phenanthrene imidazoles 26 and 44 have been identified as novel potent, selective and orally active mPGES-1 inhibitors. These inhibitors are significantly more potent than the previously reported chlorophenanthrene imidazole 1 (MF63) with a human whole blood IC50 of 0.20 and 0.14 mu M, respectively. It exhibited a significant analgesic effect in a guinea pig hyperalgesia model at oral doses as low as 14 mg/kg. Both active and selective mPGES-1 inhibitors (26 and 44) have a relatively distinct pharmacokinetic profile and are suitable for clinical development.
