The present invention provides lysine based compounds of the formula (I); and when the compound of formula (I) comprises an amino group, pharmaceutically acceptable ammonium salts thereof, wherein Rl may be, for example, (HO)2P(O)-, (NaO)2P(O)-, alkyl~CO- or cycloalkyl-CO-, wherein X may be, for example, F, Cl, and Br, and wherein R2 and R3 are as defined herein. These lysine based compounds have a physiologically cleavable unit, namely R1 , whereby upon cleavage of the unit, an HIV aspartyl protease inhibitor is released,
La présente invention concerne des composés à base de lysine de formule (I), et, lorsque le composé de formule (I) comprend un groupement aminé, les sels d~ammonium pharmaceutiquement acceptables de ceux-ci, dans laquelle Rl peut être, par exemple, (HO)2P(O)-, (NaO)2P(O)-, alkylCO- ou cycloalkyl-CO-, X pouvant être, par exemple, F, Cl, et Br, et R2 et R3 étant tels que définis dans ce texte. Ces composés à base de lysine possèdent un motif physiologiquement clivable, à savoir R1, permettant, lors du clivage du motif, la libération d~un inhibiteur de l~aspartyl-protéase du VIH,
