The present invention is concerned with compounds of formula (I), physiologically acceptable salts thereof, formulations containing them, their preparation and their use in medicine.
In formula (I)
A is a group of formula -Qk-(NQ1)m-(CH2)n-, where k and m are Independently selected from 0 and 1, provided that m can only be 0 when k is 0, n is from 1 to 6, Q1 is hydrogen or C1-4 alkyl, and Q is selected from -CO-, -CH2-, -CH2CO- and -QCH2CO-, and any of the -(CH2)n- groups are independently optionally substituted by one or two C1-4 alkyl groups;
B is group of formula -R1-C(Q2) (OH)-C(Q3) (Q4)-NQ5-R2, where R' is a bond or -OC(Q6) (Q7)- R2 is hydrogen or C1-6 alkyl, and Q2-Q7 are independently hydrogen, C1-4 alkyl, or a group of formula -(C(Q8)(Q9))×Ph, in which x is 1 or 2, Ph is a phenyl group optionally substituted by one or more groups Independently selected from hydroxy, C1-4 alkyl and C1-4 alkoxy, and Q8 and Q9 are independently hydrogen or C1-4 alkyl;
E and Z are independently selected from carboxyl and carboxyl derivatives;
D is hydrogen or a saturated or unsaturated C1-6 aliphatic substituent optionally substituted by an amino group;
G1, G2 and G3 are independently selected from hydrogen and C1-4 alkyl; (X) is a mono-, bi-, or tri-cyclic aromatic ring system optionally containing one or more heteroatoms; and
(Y) is a mono- or bi-cyclic nitrogen-containing ring system (attached to -CO-C(D)(G3)- by said nitrogen atom) optionally containing one or more other heteroatoms and optionally substituted by one or more substituents independently selected from C1-6 alkyl and aryl (e.g. phenyl), or (Y) is a nitrogen atom attached to E directly by a bond or indirectly by a C1-4 alkylene moiety and also attached to a C5-7 cycloalkyl group; in either case (Y) may optionally be linked by a C3-5 alkylene bridge to G3 or D to form a closed ring;
and physiologically acceptable salts thereof;
with the proviso that:
when, in the definition of A, k and m are both 0 or both 1 and 0 is a -CO- group, and, in the definition of B, R' is a group of formula -OC(Q6)(Q7)- as hereinbefore defined and R2 is a C1-6 alkyl group;
D is hydrogen or a C1-6 alkyl group;
(X) is a benzene ring or a naphthyl or indolyl ring system, any of which is optionally substituted in any position by one or more substituents independently selected from C1-4 alkyl (itself optionally substituted by one or more halogen atoms), C1-4 alkoxy, halo, nitro, amino, carboxyl, C1-4 alkoxycarbonyl and hydroxy,
then (Y) is not a pyrrolidinyl, oxazolidinyl, or thiazolidinyl ring, or a ring system selected from indolinyl, quinolinyl and tetrahydroquinolinyl.
