Cationic, anionic, and/or zwitterionic bis-urea compounds self-assemble by non-covalent interactions in aqueous solution to form high aspect ratio nanofibers. The nanofibers reversibly bind drugs by non-covalent interactions, forming drug compositions for exhibiting sustained release of the drug.
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.
