Patent ID: 8518912

Claim:
A compound of formula I wherein R 1 represents phenyl, wherein the phenyl is unsubstituted or substituted 1 to 3 times by substituents each independently selected from the group consisting of halogen, methyl, methoxy, trifluoromethyl and trifluoromethoxy; W represents a bond, and R 2 represents alkyl, hydroxyalkyl, alkoxyalkyl, cycloalkyl, aryl or heteroaryl; or W represents —O— and R 2 represents alkyl, cycloalkyl, hydroxyalkyl or heterocyclyl; or W represents —NR 3 —, R 2 represents alkyl, alkoxycarbonylalkyl, carboxyalkyl, hydroxyalkyl, alkoxyalkyl, heterocyclyl, cycloalkyl, aryl or aralkyl and R 3 represents hydrogen or alkyl; or W represents —NR 3 — and R 2 and R 3 form, together with the nitrogen that carries them, a heterocyclic ring of 4 to 7 members wherein the members needed to complete said heterocyclic ring are each independently selected from —CH 2 —, —CHR x —, —O—, —S—, —CO— and —NR y —, it being understood however that said heterocyclic ring does not contain more than one member selected from the group consisting of —CHR x —, —O—, —S—, —CO— and —NR y —, R x representing hydroxy, hydroxymethyl, alkoxymethyl or alkoxy and R y representing hydrogen or alkyl; or W represents —NR 3 — and R 2 and R 3 form, together with the nitrogen that carries them, an imidazolyl, pyrazolyl, 1,2,3-triazolyl or 1,2,4-triazolyl ring, which ring may be substituted by an alkyl group; R a represents hydrogen or methyl; R b represents hydrogen or methyl; R 4 represents alkoxy; n represents 0, 1, 2 or 3, V represents a bond, and m represents 0; or n represents 0 or 1, V represents phenyl, and m represents 0; or n represents 1, V represents phenyl, and m represents 1; R 5 and R 8 are identical and represent each hydroxy, unsubstituted phenyloxy, unsubstituted benzyloxy, a group —O—(CHR 6 )—O—C(═O)—R 7 , a group —O—(CHR 6 )—O—C(═O)—O—R 7 , a group —O—(CHR 6 )—C(═O)—O—R 9 , a group —NH-(CHR 10 )—C(═O)—O—R 9 or a group —NH—C(CH 3 ) 2 —C(═O)—O—R 9 ; or P(O)R 5 R 8 represents a group selected from the following structures wherein the arrow marks the point of attachment to the remaining part of compounds of formula I; R 6 represents hydrogen or (C 1 -C 3 )alkyl; R 7 represents (C 1 -C 4 )alkyl or unsubstituted (C 3 -C 6 )cycloalkyl; R 9 represents (C 1 -C 4 )alkyl; R 10 represents hydrogen, (C 1 -C 4 )alkyl, unsubstituted phenyl or unsubstituted benzyl; or a pharmaceutically acceptable salt thereof.
