Patent ID: 7378522

Claim:
A compound of general formula (I): wherein R1 (a) is an acyl group —CO—R11, wherein R11 is methyl, or b) is a carboxylic acid ester group —CO—OR12, wherein R12 is a straight or branched alkyl chain with 1-10 atoms, R2 is a group —CH(R21)R22, wherein R21 is a hydrogen atom, a C 1 -C 10 -alkyl group or an optionally substituted phenyl ring and R22 is an optionally substituted phenyl ring or naphthyl ring, or a group —CH 2 CH(R23)R24, wherein R23 and R24 are an optionally substituted phenyl ring, R3 and R4, in each case independently, are a hydrogen atom or an alkyl group with 1-10 C atoms, and R3 also can be a halogen atom, R5 is a group that is linked via radical Z, in which G is —C═C—, Z is a direct bond, the group CH—R52 or —CHR52—CH—R53-, wherein R52 and R53, independently of one another, have the meaning of a hydrogen atom, an alkyl group, a —C≡C-triple bond, L is an NH group, Q is a carbonyl group, and R51 is a straight or branched alkyl group that is optionally substituted by halogen atoms, hydroxyl or alkoxy groups, R6 is the group CH 2 —N(R61)R62, wherein R61, in each case independently, is a hydrogen atom or an alkyl group, and R62 is an optionally substituted aralkyl group with 7-20 C atoms, and —W═X═Y— is the group in any orientation; or a salt thereof with a pharmaceutically acceptable acid or base.
