Described herein are peptide derivatives of the formula R.sup.1 NH--CO--Q--C(O)--NR.sup.2 --CH[CH.sub.2 C(O)--Y]--C(O)--NH--CH[CR.sup.3 (R.sup.4)--COOH]--C(W)--NH--CHR.sup.5 --Z wherein R.sup.1 is an optionally substituted alkyl or optionally substituted phenylalkyl, R.sup.2 is hydrogen or alkyl, R.sup.3 and R.sup.4 each independently is hydrogen or alkyl, or R.sup.3 and R.sup.4 are joined to form a cycloalkyl. R.sup.5 is alkyl, cycloalkyl or (cycloalkyl)alkyl, Q is a divalent radical, for example, --CH.sub.2 CH.sub.2 --, --CH.dbd.CH-- or 1,2-cyclohexanediyl, which serves as a two carbon spacer. W is oxo or thioxo, Y is, for example, an alkoxy or a monosubstituted or disubsdtuted ammo, and Z is a terminal unit, for example, hydrogen, COOH or CH.sub.2 OH. The derivatives are useful for treating herpes infections.
本文描述了公式R.sup.1 NH--CO--Q--C(O)--NR.sup.2 --CH[CH.sub.2 C(O)--Y]--C(O)--NH--CH[CR.sup.3 (R.sup.4)--COOH]--C(W)--NH--CHR.sup.5 --Z的肽衍生物,其中R.sup.1是可选择地取代的烷基或可选择地取代的苯基烷基,R.sup.2是氢或烷基,R.sup.3和R.sup.4各自独立地是氢或烷基,或者R.sup.3和R.sup.4连接形成环烷基。R.sup.5是烷基、环烷基或(环烷基)烷基,Q是二价基团,例如,--CH.sub.2 CH.sub.2 --,--CH.dbd.CH--或1,2-环己二基,它作为两个碳原子的间隔。W是氧代或硫代,Y是,例如,烷氧基或单取代或双取代的氨基,Z是一个末端单元,例如,氢、COOH或CH.sub.2 OH。这些衍生物对治疗疱疹感染有用。
