Date Apr. 30, 1998Mercapto amino acid derivatives of formula (I), wherein R is hydrogen, a salt-forming cation of a in vivo hydrolysable ester-forming group; R1 is selected from (a) and (b) in which A is a monocyclic aryl or heteroaryl ring and B is a monocyclic aryl, alicyclic or heterocyclic ring, C and D are independently -Zp-(CR8CR9)q- or -(CR8CR9)q-Zp- where p is 0 or 1, q is 0 to 3 provided that p+q in C is not 0, R8 and R9 are independently hydrogen or (C1-6)alkyl or together represent oxo and Z is O, NR10 or S(O)x where R10 is hydrogen, (C1-6)alkyl or aryl(C1-6)alkyl and x is 0-2, and wherein C and D are linked ortho to one another on each of the rings A and B in formula (b); R2 is hydrogen, (C1-6)alkyl or aryl(C1-6)alkyl; R3 is hydrogen, (C1-6)alkyl optionally substituted by up to three halogen atoms, (C3-7)cycloalkyl, fused aryl(C3-7)cycloalkyl, (C3-7)cycloalkyl(C2-6)alkyl, (C2-6)alkenyl, (C2-6)alkynyl, aryl, aryl-(CH2)m-X-(CH2)n, heterocyclyl or heterocyclyl-(CH2)m-X-(CH2)n, where m is 0 to 3, n is 1 to 3 and X is O or S(O)x where x is 0-2 or a bond; R4 is hydrogen or an in vivo hydrolysable acyl group; and R5 and R6 are independently hydrogen and (C1-6)alkyl or together represent (CH2)r, where r is 2 to 5; for use in treatment of bacterial infections in humans or animals by administration in combination with a beta -lactam antiobiotic.

, (2008/06/13)
Novel derivatives of glycolic and glyoxylic acid are disclosed which inhibit glycolic acid oxidase and thus are useful in the treatment and prevention of calcium oxalate urolithiasis (calcium oxalate kidney and bladder stone disease).
