Abstract
The invention concerns the use of a compound of formula (I), in which Z, X, T, A, R1, R2, p and q have any of the meanings defined herein, and their pharmaceutically acceptable salts or in vivo hydrolysable esters, in the treatment of a disease or condition mediated by monocyte chemoattractant protein-1 (MCP-1). Certain of the components of formula (I) are novel and are provided, together with pharmaceutical compositions thereof, as further features of the invention.

The use of a compound of the formula (I):
- 18
- wherein
- R1 is independently selected from trifluoromethyl, C1-4alkyl, halo, hydroxy, C1-4alkoxy, C1-4alkanoyl, C1-4alkanoyloxy, carboxy, trifluoromethoxy, amino, cyano, C1-4alkylamino, di(C1-4alkyl)amino, C1-4alkanoylamino, nitro, carbamoyl, C1-4alkoxycarbonyl, thiol, C1-4alkylsulphanyl, C1-4alkylsulphinyl, C1-4alkylsulphonyl, sulphonamido, carbamoylC1-4alkyl, N—(C1-4alkyl)carbamoylC1-4alkyl, N—(C1-4alkyl)2-carbamoyl-C1-4alkyl, hydroxyC1-4alkyl, C1-4alkoxyC1-4alkyl, morpholino, pyrrolidinyl, carboxyC1-4alkylamino, R3 and —OR3 (where R3 is optionally substituted aryl or an optionally substituted 5- or 6-membered heteroaryl ring);
- p is 0-4 and R1 can have the same or different values when p is 2-4 with the proviso that no more than one R1 can be chosen from the group amino, C1-4alkylamino, di(C1-4alkyl)amino, morpholino and pyrrolidinyl;
- T is of the formula
- —(CHR4)m—,
- where R4 is independently selected from hydrogen or C1-4alkyl and m=1-3 and R4 can have different values when m is 2 or 3;
- X is CO2R4, SO3H, cyano, —SO2NHR4 (where R4 is as defined above), —SO2NHAr (where Ar is an optionally substituted phenyl or optionally substituted 5 or 6 membered heteroaryl ring), —CONHR5 (where R5 is H, cyano, C1-4alkyl, OH, —SO2—C1-4alkyl, —SO2CF3, —SO2-phenyl, —(CHR4)r—COOH, (where r is 1-3 and R4 (as defined above) can take different values when r is 2-3)), or X is a group of formula (II)
- 19
- or X represents a group of formula (III)
- 20
- where the groups defined as R4 may have different values within the definition of R4 above;
- A is selected from phenyl, naphthyl, furyl, pyridyl and thienyl;
- R2 is independently selected from trifluoromethyl, C1-4alkyl, halo, hydroxy, CF3O—,
- C1-4alkoxy, C1-4alkanoyl, C1-4alkanoyloxy, amino, cyano, C1-4alkylamino, (C1-4alkyl)2amino, C1-4alkanoylamino, nitro, carboxy, carbamoyl, C1-4alkoxycarbonyl, thiol, C1-4alkylsulphanyl, C1-4 alkylsulphinyl, C1-4alkylsulphonyl, sulphonamido, carbamoylC1-4alkyl, N-(C1-4alkyl)carbamoylC1-4alkyl, N—(C1-4alkyl)2carbamoyl-C1-4alkyl, hydroxyC1-4alkyl, C1-4alkoxyC1-4alkyl or two R2 values together may form a divalent radical of the formula —O(CH2)1-4O— attached to adjacent carbon atoms on ring A;
- q is 0-4 and R2 can have the same or different values when q is 2-4;
- Z is hydrogen, fluoro, chloro, bromo, iodo, methyl, trifluoromethyl, hydroxymethyl, acetyl, carboxyC3-6cycloalkyl or —(CHR4)r—NR6R7 (where r is 0-2, R6 and R7 are independently selected from H and C1-4alkyl or R6 and R7 together with the nitrogen to which they are attached form a 5 or 6 membered non-aromatic ring optionally containing one further heteroatom selected from O, N or S);
- or a pharmaceutically acceptable salt or an in vivo hydrolysable ester thereof;
- in the manufacture of a medicament for antagonising an MCP-1 mediated effect in a warm-blooded animal.
The use of a compound is claimed in any preceding claim wherein A(R2)q or A′(Rf)y is 3-chlorophenyl, 4-chlorophenyl, 3-fluorophenyl, 4-fluorophenyl, 3-trifluoromethylphenyl, 3,4-dichlorophenyl or 3,4-difluorophenyl.
The use of a compound as claimed in any preceding claim wherein X or X′ is carboxy.
A compound of the formula (A):
- 22
- wherein
- Ra is 4-methoxy, 4-phenyl, 4-amino, 4-thien-2-yl, 5-chloro, 5-methoxy, 5-nitro, 5-bromo, 5-phenoxy, 5-fluoro, 5-carboxymethylamino, 5-amino, 6-fluoro, 6-trifluoromethyl, 6-nitro or 6-chloro;
- c is 0, 1 or 2 provided that there is no more than one methoxy group;
- W is hydrogen, bromo, methyl or transcyclopropyl-2-carboxylic acid;
- G is phenyl or thien-2-yl;
- When G is phenyl Rb is 3-chloro, 3-trifluoromethyl, 3-nitro, 3-methoxy, 4-trifluoromethyl, 4-trifluoromethoxy or 4-chloro;
- When G is thien-2-yl Rb is 5-chloro;
