  • Imidazopyridine compounds
    Patent number: 9447090
    Abstract: An excellent drug for treating or preventing cardiovascular diseases, based on cGMP production enhancing action due to soluble guanylate cyclase activating action, is provided. It was found that imidazopyridine compounds having a carbamoyl group at the 3-position and a substituent bonded at the 8-position via an oxygen atom in an imidazo[1,2-a]pyridine skeleton exhibits a cGMP production enhancing action by a potent soluble guanylate cyclase activating action, and is useful as a drug for treating or preventing various soluble guanylate cyclase-related cardiovascular diseases, thereby completing the present invention.
