alkanoyl, fluoromethyl, difluoromethyl trifluoromethyl and trifluoromethoxy; or a pharmaceutically acceptable salt or pro-drug thereof; possess glycogen phosphorylase inhibitory activity and accordingly have value in the treatment of disease states associated with increased glycogen phosphorylase activity. Processes for the manufacture of said heterocyclic amide derivatives and pharmaceutical compositions containing them are described.
式(1)的杂环酰胺,其中:R1独立地选择自C1-6烷基、C5-7环烷基、C5-7环烷基C1-3烷基、C1-6烷氧基、C5-7环烷氧基、C5-7环烷基C1-3烷氧基、杂环基、杂环基C1-3烷基、杂环氧基或杂环基C1-3烷氧基;R2为苯基或杂环芳基;R3独立地选择自氢、卤素、硝基、氰基、羟基、羧基、氨基甲酰、C1-4烷基、C2-4烯基、C2-4烷基、C1-4烷氧基、C1-4酰基、氟甲基、二氟甲基、三氟甲基和三氟甲氧基;或其药学上可接受的盐或前药。该化合物具有糖原磷酸化酶抑制活性,因此在治疗与糖原磷酸化酶活性增加相关的疾病状态中具有价值。描述了制备该杂环酰胺衍生物和含有它们的制药组合物的工艺。
