ABSTRACT:
The present invention concerns the compounds having the formulaN-oxides, salts, stereoisomeric forms, racemic mixtures, prodrugs, esters and metabolites thereof, wherein R1and R8each are H, optionally substituted C1-6alkyl, C2-6alkenyl, C3-7cycloalkyl, aryl, Het1, Het2; R1may also be a radical of formula (R11aR11b)NC(R10aR10b)CR9—; t is 0, 1 or 2; R2is H or C1-6alkyl; L is —C(═O)—, —O—C(═O)—, —NR8—C(═O)—, —O—C1-6alkanediyl-C(═O)—, —NR8—C1-6alkanediyl-C(═O)—, —S(═O)2—, —O—S(═O)2—, —NR8—S(═O)2; R3is C1-6alkyl, aryl, C3-7cycloalkyl, C3-7cycloalkylC1-4alkyl, or arylC1-4alkyl; R4is H, C1-4alkylOC(═O), carboxyl, aminoC(═O), mono- or di(C1-4alkyl)aminoC(═O), C3-7cycloalkyl, C2-6alkenyl, C2-6alkynyl or optionally substituted C1-6alkyl; R5and R6are H or C1-6alkyl. It further relates to their use as broadspectrum HIV protease inhibitors, processes for their preparation as well as pharmaceutical compositions and diagnostic kits comprising them. It also concerns combinations thereof with another anti-retroviral agent, and to their use in assays as reference compounds or as reagents.
