The present invention relates to certain novel heterocyclic ketones which are 1-pyridylacetamide ketones of formula I, set out herein, which are inhibitors of human leukocyte elastase (HLE), also known as human neutrophil elastase (HNE), making them useful whenever such inhibition is desired, such as for research tools in pharmacological, diagnostic and related studies and in the treatment of diseases in mammals in which HLE is implicated. The invention also includes intermediates useful in the synthesis of these heterocyclic ketones, processes for preparing the heterocyclic ketones, pharmaceutical compositions containing such heterocyclic ketones and methods for their use.
本发明涉及某些新颖的杂环酮,这些酮是式I所示的1-吡啶基乙酰胺酮,该酮是人类白细胞弹性蛋白酶(HLE)的抑制剂,也被称为人类中性粒细胞弹性蛋白酶(HNE),使其在需要抑制时具有用处,例如用作药物学、诊断和相关研究工具以及治疗哺乳动物中HLE涉及的疾病。该发明还包括合成这些杂环酮的中间体,制备杂环酮的方法,含有这种杂环酮的药物组合物以及其使用方法。
