The present invention relates to certain novel substituted ketones which are 1-pyrimidinylacetamide derivatives of formula I, ##STR1## 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 ##STR2## useful in the synthesis of these substituted ketones processes for preparing the substituted ketones pharmaceutical compositions containing such substituted ketones and methods for their use.
本发明涉及一种新的取代酮,它们是公式I的1-嘧啶基乙酰胺衍生物,如下所示:##STR1## 这些化合物是人类白细胞弹性蛋白酶(HLE),也称为人类中性粒细胞弹性蛋白酶(HNE)的抑制剂,因此在需要这种抑制剂的情况下,如在药理学、诊断和相关研究中作为研究工具以及在与HLE有关的哺乳动物疾病的治疗中,它们是有用的。本发明还包括中间体##STR2## 用于合成这些取代酮,以及制备这些取代酮的方法、含有这些取代酮的制药组合物以及它们的使用方法。
