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.
以下是公式I*的描述,##STR1## 其中R.sub.1是低级烷氧羰基,R.sub.2是二级或三级低级烷基或低级烷基硫基-低级烷基,R.sub.3是未取代或由一个或多个低级烷氧基团取代的苯基,或者是C.sub.4 -C.sub.8环烷基,R.sub.4是苯基或环己基,每个在4位上取代有不饱和杂环,该杂环通过环碳原子连接,具有5到8个环原子,含有1到4个选自氮、氧、硫、亚磺酰基(--SO--)和磺酰基(--SO.sub.2--)的杂原子,并且未取代或由低级烷基或苯基-低级烷基取代,R.sub.5独立于R.sub.2,具有R.sub.2所述的一个含义,而R.sub.6独立于R.sub.1,是低级烷氧羰基,或其盐类,前提是至少存在一个成盐基团。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。它们展现出卓越的药效动力学特性。
