Disclosed herein are tetrapeptide derivatives of the formula X-NH-CHR<1>-C(W<1>)-NR<2>-CH[CH2C(O)-Y]-C(W<2>)-NH-CH[CR<3>(R<4>)-COOH ]-C(W<3>)- NH -C HR <5>- Z wherein X is a terminal group, for example, alkanoyl or phenylalkanoyl radicals, R<1> and R<5> are selected from amino acid or derived amino acid residues, R<2> is hydrogen, alkyl or phenylalkyl, R<3> and R<4> are hydrogen or alkyl or R<3> and R<4> are joined to form a cycloalkyl, W<1>, W<2> and W<3> are oxo or thioxo, Y is, for example, an alkoxy or a monosubstituted or disubstituted amino, and Z is a terminal unit, for example, hydrogen, COOH or CH2OH. The derivatives are useful for treating herpes infections. |
