Compounds useful as inhibitors of the enzyme elastase are of the following general formula: ##STR1## wherein Z is selected from the group consisting of R"O--Suc-- where R" is lower alkyl of 1 to 3 carbon atoms and CF.sub.3 CO--; X is oxygen or sulfur; R' is selected from the group consisting of straight or secondary branch-chained alkyl of 1 to 4 carbon atoms, alkenyl of 2 to 3 carbon atoms, alkynyl of 2 to 4 carbon atoms, cycloalkyl of 3 to 6 carbon atoms, and benzyl, and R is selected from the group consisting of susbstituted or unsubstituted phenyl wherein the substituents are selected from the group consisting of nitro, and pentafluoro; benzyl, CH.sub.2 CF.sub.2 CF.sub.2 CF.sub.3, 1-lower alkyl tetrazolyl, 1-phenyltetrazolyl, 2-thioxo-3-thiazolidinyl-, pyridyl and benzothiazolyl, provided that when R is paranitrophenyl, R' is other than tertiary-butyl, benzyl or cyclohexyl, and when X is sulfur, R is other than benzyl.
以下是酶弹性蛋白酶抑制剂的通用公式:##STR1## 其中Z从R"O--Suc--组成的群体中选择,其中R"是1到3个碳原子的低碳烷基和CF.sub.3 CO--; X是氧或硫;R'从1到4个碳原子的直链或次级支链烷基,2到3个碳原子的烯烃基,2到4个碳原子的炔烃基,3到6个碳原子的环烷基和苄基中选择,R从取代或未取代的苯基中选择,其中取代基从硝基和五氟取代基中选择;苄基,CH.sub.2 CF.sub.2 CF.sub.2 CF.sub.3,1-低碳烷基四唑基,1-苯基四唑基,2-硫代-3-噻唑烷基-,吡啶基和苯并噻唑基,条件是当R为对硝基苯基时,R'不是叔丁基、苄基或环己基,且当X为硫时,R不是苄基。
