The present invention relates to a compound of formula I STR1 or a nontoxic pharmaceutically acceptable salt, physiologically hydrolyzable ester or solvate thereof, in whichX is --O--CO--, --NH--CO--, --CS--NH--, --CO--O--, --CO--NH--, --COS--, --SCO--, --SCH 2 --, --CH 2 --CH 2 --, --C C--, --CH 2 --NH--, --COCH 2 --, --NHCS--, --CH 2 S--, --CH 2 O--, --OCH 2 --, --NHCH 2 -- or --CR 5 CR 6 --;R m and R k are independently hydrogen, halogen, C 1-6 alkyl, hydroxy, C 1-6 alkyloxy or nitro;n is zero or one;R 4 is --(CH 2) t --Y, C 1-6 alkyl, or C 3-6 cycloalkyl;R 1 is --CO 2 Z, C 1-6 alkyl, CH 2 OH, --CONHR y, or CHO;R 2 and R 3 are independently hydrogen or C 1-6 alkyl;R a and R b are independently hydrogen or C 1-6 alkyl; but when n is one, R a and R b together can form a radical of the formula STR2 Y is naphthyl or phenyl, both radicals can be optionally substituted with one to three same or different C 1-6 alkyl or halogen;Z is hydrogen or C 1-6 alkyl;R 5, R 6 and R y are independently hydrogen or C 1-6 alkyl; andt is zero to six.
