Claim:
A compound of formula: wherein R 1 is a group of the formula where A is hydrogen, hydroxy, amino, or halogen and B is amino, carboxy, hydrogen, hydroxy, cyano, trifluoromethyl, halogen, lower alkyl, or lower alkoxy; R 2 is a group of the formula where R 3 is hydrogen, carboxy, or lower alkyl; n is 0 or 1; U, V, and W are independently hydrogen, halogen, or lower alkyl provided U and V are not both hydrogen; X is carbonyl, phenyl-substituted loweralkylene, or sulfonyl; Y is lower alkylene which may be substituted with one or more of amino, substituted amino, lower alkyl, or cyclo lower alkyl, or Y is lower alkenylene or lower alkylenethio; and k is 0 or 1; when k is 1: Z is hydrogen, lower alkylthio, —COOH, —CONH 2 , or amino, or when k is 0 or 1, Z is: 1-adamantyl, diphenylmethyl, 3-[[(5-chloropyridin-2-yl)amino]carbonyl]pyrazin-2-yl, hydroxy, phenylmethoxy, 2-chloro-4-[[[(3-hydroxyphenyl)methyl]amino]carbonyl]phenyl, [(2,6-dichlorophenyl)methoxy]phenyl, or Z is one of the following: cycloalkyl or aryl containing 0 to 3 heteroatoms which may be the same or different, or a fused ring system containing two or three rings which rings are independently cycloalkyl or aryl containing 0 to 3 heteroatoms which may be the same or different, any of which rings may be unsubstituted, or substituted with at least one of: halogen, cyano, amino, substituted amino, aminosulfonyl, nitro, oxo, hydroxy, aryl, aryloxy, unsubstituted lower alkyl, halogen-substituted lower alkyl, lower alkoxy-substituted lower alkyl, lower alkoxy, lower alkanesulfonyl, lower alkylthio, acetyl, aminocarbonyl, hydrazino, carboxy, lower alkoxycarbonyl, acetoxy or amino loweralkyl; or a pharmaceutically acceptable salts and esters thereof.
