Disclosed herein are compounds of formula 1 ##STR1## wherein X is a terminal group, for example, an aryloxycarbonyl, an alkanoyl or an optionally mono- or disubstituted carbamoyl; B is absent or an amino acid residue, for example, Val or Ash; R.sup.1 is hydrogen or a ring substituent, for example, fluoro or methyl; R.sup.2 is alkyl; and Y is a ring substituent, for example, phenoxy, 2-pyridinylmethoxy, phenylthio or 2-pyridinylthio. The compounds inhibit the activity of human immunodeficiency virus (HIV) protease and interfere with HIV induced cytopathogenic effects in human cells. These properties render the compounds useful for combating HIV infections.
本文揭示了公式1的化合物 ##STR1## 其中X是末端基团,例如芳氧羰基,烷酰基或可选的单取代或双取代的
氨基酰基; B是不存在或是
氨基酸残基,例如瓦尔或阿什; R.sup.1是氢或环取代基团,例如
氟或甲基; R.sup.2是烷基; 而Y是环取代基团,例如苯氧基,2-
