There are described compounds of formula I*, ##STR1## wherein R.sub.1 is lower alkoxycarbonyl, R.sub.2 is secondary or tertiary lower alkyl or lower alkylthio-lower alkyl, R.sub.3 is phenyl that is unsubstituted or substituted by one or more lower alkoxy radicals, or C.sub.4 -C.sub.8 cycloalkyl, R.sub.4 is phenyl or cyclohexyl each substituted in the 4-position by unsaturated heterocyclyl that is bonded by way of a ring carbon atom, has from 5 to 8 ring atoms, contains from 1 to 4 hetero atoms selected from nitrogen, oxygen, sulfur, sulfinyl (--SO--) and sulfonyl (--SO.sub.2 --) and is unsubstituted or substituted by lower alkyl or by phenyl-lower alkyl, R.sub.5, independently of R.sub.2, has one of the meanings mentioned for R.sub.2, and R.sub.6, independently of R.sub.1, is lower alkoxycarbonyl, or salts thereof, provided that at least one salt-forming group is present. The compounds are inhibitors of retroviral aspartate protease and can be used, for example, in the treatment of AIDS. They exhibit outstanding pharmacodynamic properties.
该文描述了式I*的化合物,其中R.sub.1是较低的烷氧羰基,R.sub.2是次级或三级较低的烷基或较低的烷基硫醇-较低的烷基,R.sub.3是苯基,该苯基未取代或被一个或多个较低的烷氧基取代,或C.sub.4-C.sub.8环烷基,R.sub.4是苯基或环己基,每个基在4-位被不饱和杂环基取代,该不饱和杂环基通过环碳原子连接,具有5至8个环原子,包含从氮、氧、硫、亚砜(--SO--)和磺酰基(--SO.sub.2--)中选择的1至4个杂原子,未取代或被较低的烷基或苯基-较低的烷基所取代,R.sub.5与R.sub.2独立,具有R.sub.2提及的含义之一,R.sub.6与R.sub.1独立,是较低的烷氧羰基或其盐,至少存在一个盐基团。这些化合物是逆转录病毒天冬氨酸蛋白酶的抑制剂,例如可以用于治疗艾滋病。它们表现出优异的药理学性质。
