  • 2-PHENYL SUBSTITUTED IMIDAZOTRIAZINONES AS PHOSPHODIESTERASE INHIBITORS
    Publication number: 20130059844
    Abstract: The 2-phenyl-substituted imidazotriazinones having short, unbranched alkyl radicals in the 9-position are prepared from the corresponding 2-phenyl-imidazotriazinones by chlorosulphonation and subsequent reaction with the amines. The compounds inhibit cGMP-metabolizing phosphodiesterases and are suitable for use as active compounds in pharmaceuticals, for the treatment of cardiovascular and cerebrovascular disorders and/or disorders of the urogenital system, in particular for the treatment of erectile dysfunction.
