Compounds of formula (I) :
[wherein: R¹ is hydrogen, alkyl, aralkyl, -CORa, -CORb, -CSRa, -CSRb, -SO₂Rb, -CONHRb, -CSNHRb, -CONRbRb or -CSNRbRb; R² is hydrogen or alkyl; R³ is hydrogen, alkylidene, substituted alkyl, or Rb; R⁴ is optionally substituted alkyl, cycloalkyl, or aryl; R⁵ is RbO-, RbRbN-, RbHN-, aralkyloxycarbonyloxy or aralkyloxycarbonylamino, or R⁵ is -(CH₂)p-D-(CH₂)r- [where D is a single bond, carbonyl, oxygen, sulphur, -NH-, -(CH₂=CH₂)- or -NHCO-; and p and r are each 0 or an integer from 1 to 5]; A is -(CH₂)m-B-(CH₂)n- [where B is a single bond, carbonyl, oxygen, sulphur, -NH-, -(CH₂=CH₂)- or -NHCO-; and m and n are each 0 or an integer from 1 to 5]; Ra is alkoxy, aralkyloxy, aryloxy or alkoxycarbonyl; Rb is optionally substituted alkyl, cycloalkyl, heterocyclic, aryl or arylalkenyl]; and pharmaceutically acceptable salts and esters thereof and pro-drugs therefor, have the ability to inhibit the activity of HIV protease and may thus be used for the treatment and prophylaxis of AIDS.
化合物的化学式为(I):[其中:R¹为氢,烷基,芳基烷基,-CORa,-CORb,-CSRa,-CSRb,-SO₂Rb,-CONHRb,-CSNHRb,-CONRbRb或-CSNRbRb;R²为氢或烷基;R³为氢,烷基亚甲基,取代烷基或Rb;R⁴为可选取代的烷基,环烷基或芳基;R⁵为RbO-,RbRbN-,RbHN-,芳基烷氧羰氧基氧或芳基烷氧羰氨基,或R⁵为-(CH₂)p-D-(CH₂)r- [其中D为单键,酰基,氧,硫,-NH-,-(CH₂=CH₂)-或-NHCO-;p和r分别为0或1到5的整数];A为-(CH₂)m-B-(CH₂)n- [其中B为单键,酰基,氧,硫,-NH-,-(CH₂=CH₂)-或-NHCO-;m和n分别为0或1到5的整数];Ra为烷氧基,芳基烷氧基,芳氧基或烷氧羰基;Rb为可选取代的烷基,环烷基,杂环,芳基或芳基烷烯基];以及其药学上可接受的盐和酯以及其前药,具有抑制HIV蛋白酶活性的能力,因此可用于治疗和预防艾滋病。
