Disclosed are compounds of general formula (I) and pharmaceutically acceptable salts thereof wherein R1 is H, hydroxy or NHR2 wherein R2 is H, alkyl, alkenyl, alkynyl, arylalkyl, heterocyclyalkyl, cycloalkyl, alkyl carbonyl, cycloalkyl carbonyl, aryl carbonyl, heterocyclyl carbonyl, aryl alkyl carbonyl, heterocyclyl alkyl carbonyl, alkyl oxy carbonyl, aryl alkyl oxy carbonyl, heterocyclyl alkyl oxy carbonyl, aryl heterocyclyl sulfonyl, alkyl sulfonyl, aryl sulfonyl, heterocyclyl sulfonyl or a group of formula (A) wherein X is O or S and R7 and R8 independently are H, alkyl, aryl, heterocyclyl, aryl alkyl, heterocyclyl alkyl or R7 an R8 together with the notrogen atom to which they are attached form a saturated ring optionally containing a further hetero atom or a group (B) wherein when n=1, Y represents N, R9 is H or alkyl and R10 H, alkyl, aryl, alkyl, heterocyclyl alkyl, aryl, heterocyclyl or R9 and R10 taken together with the hetero atom to which they are attached form a heterocycle R11 and R12 independently are H or alkyl or R11 and R12 taken together with the carbon atom to which they are attached form a cycle, R3, R4 independently are alkyl or taken together with the carbon atom to which they are attached form a carbocycle, R5 is alkyl, aryl alkyl, heterocyclyl alkyl or R4 and R5 taken together with the carbon and sulfur atom to which they are attached form a heterocycle and R6 is alkyl, aryl alkyl, heterocyclyl alkyl, alkyl oxy alkyl, hydroxy alkyl, amino alkyl, fluoro alkyl and R13 is H or the residue of an inorganic ester and R15 is aryl, with the proviso that, if R3, R4 and R5 are methyl, R6 is tert.butyl, R13 is H and if R15 is phenyl R2 is not benzyl oxycarbonyl and not 2-quinoline carbonyl. The compounds of formula (I) are potent inhibitors of the HIV aspartyl protease and can therefore be used in the treatment of HIV related diseases.
