Abstract:
A method of inhibiting a retroviral protease comprising administering a protease inhibiting amount of a compound represented by Formula (I): ##STR96## or a pharmaceutically acceptable salt, prodrug, or ester thereof, wherein: R represents alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, heterocycloalkyl, heterocycloalkylalkyl, aryl, heteroaryl, aralkyl, heteroaralkyl, aminocarbonylalkyl, aminoalkylcarbonylalkyl, hydroxyalkyl, alkoxyalkyl, alkylcarbonylalkyl, aryloxyalkylcarbonylalkyl, and aralkoxycarbonylalkyl radicals;R.sup.1 represents hydrogen, --CH.sub.2 SO.sub.2 NH.sub.2, --CH.sub.2 CO.sub.2 CH.sub.3, --CO.sub.2 CH.sub.3, --CONH.sub.2, --CH.sub.2 C(O)NHCH.sub.3, --C(CH.sub.3).sub.2 (SCH.sub.3), --C(CH.sub.3).sub.2 (S[O]CH.sub.3), --C(CH.sub.3).sub.2 (SH), --C(CH.sub.3).sub.2 (S[O].sub.2 CH.sub.3), alkyl, haloalkyl, alkenyl, alkynyl, and cycloalkyl radicals, and amino acid side chains selected from asparagine, S-methyl cysteine and the sulfoxide (SO) and sulfone (SO.sub.2) derivatives thereof, isoleucine, allo-isoleucine, alanine, leucine, tert-leucine, phenylalanine, ornithine, histidine, norleucine, glutamine, threonine, glycine, allo-threonine, serine, O-methyl serine, aspartic acid, beta-cyano alanine, and valine side chains;R.sup.2 represents alkyl, aryl, cycloalkyl, cycloalkylalkyl, and aralkyl radicals, which radicals are optionally substituted with a group selected from halogen and alkyl radicals, NO.sub.2, --C.tbd.N, CF.sub.3, OR.sup.9 and SR.sup.9 wherein R.sup.9 represents hydrogen and alkyl radicals; andR.sup.3 and R.sup.4 independently represent alkyl, haloalkyl, alkenyl, alkynyl, hydroxyalkyl, alkoxyalkyl, cycloalkyl, cycloalkylalkyl, heterocycloalkyl, heteroaryl, heterocycloalkylalkyl, aryl, aralkyl, heteroaralkyl, aminoalkyl, and mono- and disubstituted aminoalkyl radicals, wherein said substituents are selected from alkyl, aryl, aralkyl, cycloalkyl, cycloalkylalkyl, heteroaryl, heteroaralkyl, heterocycloalkyl, and heterocycloalkylalkyl radicals, or in the case of a disubstituted aminoalkyl radical, said substituents along with the nitrogen atom to which they are attached, form a heterocycloalkyl or a heteroaryl radical;with the proviso that at least one of R.sup.3 and R.sup.4 represents cycloalkyl, cycloalkylalkyl, heterocycloalkyl, heteroaryl, heterocycloalkylalkyl, aryl, aralkyl, heteroaralkyl, and mono- and disubstituted aminoalkyl radicals, wherein said substituents are selected from cycloalkyl, cycloalkylalkyl, heteroaryl, heteroaralkyl, heterocycloalkyl, and heterocycloalkylalkyl radicals, or in the case of a disubstituted aminoalkyl radical, said substituents along with the nitrogen atom to which they are attached, form a heterocycloalkyl or a heteroaryl radical.
