| 摘要 |
This invention is directed to compounds of formula (I): wherein R<1> is mercapto, acetylthio, carboxy, hydroxycarbamoyl, alkoxycarbonyl, aryloxycarbonyl, aralkoxycarbonyl, benzyloxycarbamoyl or (i) (where R<6> is optionally substituted aryl, wherein the aryl group is quinol-2-yl, naphth-1-yl, naphth-2-yl, pyridyl or phenyl); R<2> is alkyl, aralkyl or cycloalkylalkyl; R<3> is cycloalkyl, alkyl (optionally substituted by cycloalkyl, hydroxy, mercapto, alkylthio, aralkoxy, carboxy, amino, alkylamino, guanidino, carbamoyl, pyridyl or indolyl), or aralkyl (optionally substituted by hydroxy, carboxy, alkyl or alkoxy); R<4> is nitro, amino, cyano, hydroxy, alkoxy, carboxy, alkoxycarbonyl, alkylsulfonyl, haloalkyl, alkoxycarbonylalkyl, tetrazolyl, carbamoyl (optionally substituted by alkyl or dialkylaminoalkyl), or aminosulfonyl (optionally substituted by alkyl); and R<5> is hydrogen, halo or hydroxy; as single stereoisomers or as mixtures thereof; or the pharmaceutically acceptable salts thereof. These compounds are useful in inhibiting matrix metalloprotease activity in mammals.
