摘要:
Disclosed herein are peptides of the formula Y-R¹-R²-R³-R⁴-R⁵-R⁶-Z wherein R¹ to R⁵ are designated amino acid residues; R⁶ is Phe, homoPhe or an amino acid residue derived from 2-amino-3-cyclohexylpropionic acid, 2-amino-3-(4-lower alkoxy)phenyl)propionic acid or 2-amino-3-(4-halophenyl)propionic acid; Y is Phe, desamino-Phe, (lower alkanoyl)-Phe, p-haloPhe, Tyr, desamino-Tyr or (lower alkanoyl)-Tyr, or Y is the decapeptide radical W-Val-R⁷-Ser-R⁸-R⁹-Thr-Glu-R¹⁰-Ser-Phe wherein W is hydrogen or lower alkanoyl and R⁷ to R¹⁰ are designated amino acids residues, or Y is a fragment of the decapeptide radical wherein from one to nine of the amino acid residues (i.e. Val to Ser) may be deleted serially from the amino terminus of the decapeptide radical; and Z is hydroxy, amino, lower alkylamino or di(lower alkyl)amino. The peptides inhibit mammalian ribonucleotide reductase and are indicated for preventing or ameliorating abnormal cell proliferation.
wherein X is a terminal group, for example, an aryloxycarbonyl, an alkanoyl or an optionally mono- or disubstituted carbamoyl; B is absent or an amino acid residue, for example, Val or Asn; R¹ is hydrogen or a ring substituent, for example, fluoro or methyl; R² is alkyl; and Y is a ring substituent, for example, phenoxy, 2-pyridinylmethoxy, phenylthio or 2-pyridinylthio. The compounds inhibit the activity of human immunodeficiency virus (HIV) protease and interfere with HIV induced cytopathogenic effects in human cells. These properties render the compounds useful for combating HIV infections.
