Patent ID: 7605261

Claim:
A compound of Formula I or a pharmaceutically acceptable salt thereof, wherein: Y is an oxygen or sulphur atom, Z is —C(═CH 2 )—, —CH(CH 3 )— R 1 is an optionally substituted morpholinyl radical or a saturated diamine radical of formula: radical, wherein the continuous arc indicates that the two nitrogen atoms form a monocyclic, heterocyclic, saturated, optionally substituted radical constituted by at most 8 members, the nitrogen atoms optionally being consecutive on the ring thus formed; X is a linear or branched alkylene radical containing at most 6 carbon atoms; R 4 is the hydrogen atom, an esterified carboxy radical, or an optionally substituted linear or branched alkyl radical containing at most 4 carbon atoms; R 5 and R 6 , which could be identical or different, are the hydrogen atom, an optionally substituted linear or branched alkyl radical containing at most 4 carbon atoms; R 2 is a linear or branched alkyl radical containing at most 6 atoms substituted by one or more identical or different radicals chosen from the aryl or heteroaryl radicals themselves optionally substituted; R 3 is a linear or branched alkyl radical containing at most 6 carbon atoms, cycloalkyl containing at most 12 members, aryl, heteroaryl, arylalkyl or heteroarylalkyl in which the alkyl radical is linear or branched containing at most 4 carbon atoms, all these radicals being optionally substituted.
