Indolinesulphanilic acid amides as ppar-delta modulators

A compound of formula (I)

• in which
• R1 represents phenyl or represents 5- or 6-membered heteroaryl having up to two heteroatoms from the group consisting of N, O and S, which radicals may for their part each be mono- to trisubstituted by identical or different substituents selected from the group consisting of halogen, cyano, nitro, (C1-C6)-alkyl (which for its part may be substituted by hydroxyl), (C1-C6)-alkoxy, trifluoromethyl, trifluoromethoxy, (C1-C6)-alkylsulphonyl, (C1-C6)-alkanoyl, (C1-C6)-alkoxycarbonyl, carboxyl, amino, (C1-C6)-acylamino, mono- and di-(C1-C6)-alkylamino,
• R2 and R3 are identical or different and independently of one another represent hydrogen or (C1-C4)-alkyl or together with the carbon atom to which they are attached form a 3- to 7-membered spiro-linked cycloalkyl ring,
• R4 represents hydrogen or (C1-C4)-alkyl,
• R5 represents hydrogen, (C1-C4)-alkyl, (C1-C4)-alkoxy or halogen,
• R6 represents (C1-C6)-alkyl, (C3-C8)-cycloalkyl, (C1-C6)-alkanoyl, (C1-C6)-alkylsulphonyl or (C1-C6)-alkoxycarbonyl,
• R7 and R8 are identical or different and independently of one another represent hydrogen or (C1-C4)-alkyl,
• and
• R9 represents hydrogen or a hydrolyzable group which can be degraded to the corresponding carboxylic acid,
• or a pharmaceutically acceptable salt thereof.
