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.
描述了化合物I*的公式,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基烷基,R.sub.3是苯基,未取代或取代了一个或多个较低的烷氧基,或C.sub.4-C.sub.8环烷基,R.sub.4是苯基或环己基,每个取代在4位的不饱和杂环基,通过环碳原子连接,具有5至8个环原子,包含1至4个从氮、氧、硫、亚砜(-SO-)和磺酰(-SO.sub.2 -)中选择的杂原子,并且未取代或取代了较低的烷基或苯基较低的烷基,R.sub.5与R.sub.2独立,具有R.sub.2提到的含义之一,R.sub.6与R.sub.1独立,是较低的烷氧羰基或其盐,至少存在一个盐形成基团。这些化合物是反转录病毒天冬氨酸蛋白酶的抑制剂,例如可用于治疗艾滋病。它们具有优异的药效学性质。
