The present invention relates to particular forms of a novel 1-substituted-N-\x9b2-methyl-1-(trifluoroacetyl)propyl!pyrrolidine-2-carboxam ide 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 pharmaceutical compositions containing such forms, processes for preparing the forms and intermediates useful in the synthesis of the forms.
本发明涉及一种新型1-取代-N-\x9b2-甲基-1-(三
氟乙酰基)丙基!
吡咯烷-2-羧酰胺的特定形式,它们是人类白细胞
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,使它们在需要抑制HLE的情况下非常有用,例如用于药理学、诊断和相关研究的研究工具以及治疗哺乳动物中HLE参与的疾病。本发明还包括含有这种形式的制药组合物,制备这种形式的过程以及在合成这种形式中有用的中间体。
