| abstract |
The invention relates to compounds of the formula I, wherein R1, R2, R3 and R4 are each independently selected from H, (1-4C)alkyl, (1-4C)alkoxy, trifluoromethyl, trifluoromethoxy, halogen, amino, sulfonamide, cyano, OH and nitro; R5 is H or (1-6C)alkyl; R6 is H, (1-6C)alkyl or (1-6C)alkoxy; R7 is H or (1-6C)alkyl; R8 is (1-6C)alkyl, optionally substituted with (1-6C)alkoxy; R9 is -(CH2)nR10, wherein n is 1, 2 or 3 and R10 is selected from (1-4C)alkoxy, (1-4C)alkylthio, trifluoromethyl, (3-8C)cycloalkyl, phenyl optionally substituted with (1-4C)alkoxy, -NR11R12 and -O(CH2)2NR11R12, wherein one of R11 and R12 is (1-4C)alkoxy, the other being H or (1-4C)alkyl, or R9 is -CH2(2-7C)heterocycloalkyl, provided that when at least one heteroatom in the heterocycloalkyl moiety is nitrogen, the distance between this nitrogen and the nitrogen in 'NHR9' is at least three carbon atoms, or R9 is -(CH2)3(2-7C)heterocycloalkyl or -(CH2)2CHR13R14, wherein R13 and R14 together with the carbon atom to which they are attached, are (2-7C)heterocycloalkyl; and X is O, S or NH; or a pharmaceutically acceptable salt thereof. The compounds of the invention are Il-8 receptor modulators, in particular inhibitors thereof, and can be used for treating or preventing Il-8 receptor mediated disorders, such as atherosclerosis, inflammation, rheumatoid arthritis and related disorders. |
