ABSTRACT:
A compound of formula (I) or a pharmaceutically-acceptable salt, solvate or stereoisomer thereof wherein R1is a group chosen from —CH2OH and —NHC(O)H; R2is a hydrogen atom or R1together with R2form the group —NH—C(O)—CH═CH—, wherein the nitrogen atom is bound to the carbon atom in the phenyl ring holding R1and the carbon atom is bound to the carbon atom in the phenyl ring holding R2; R3is chosen from a hydrogen atom, a halogen atom and groups chosen from —SO—R5, —SO2—R5, —NH—CO—NH2, —CO—NH2, hydantoino, C1-4alkyl, C1-4alkoxy and —SO2NR5R6; R4is chosen from a hydrogen atom, a halogen atom and a C1-4alkyl group; R5is chosen from a C1-4alkyl group and a C3-8cycloalkyl group; R6is independently chosen from a hydrogen atom and a C1-4alkyl group; n, p and q are independently 0, 1, 2, 3 or 4; m and s are independently 0, 1, 2 or 3; and r is 0, 1 or 2 with the provisos that at least one of m and r is not 0, the sum n+m+p+q+r+s is 7, 8, 9, 10, 11, 12 or 13, and the sum q+r+s is 2, 3, 4, 5 or 6.
