Claim 2:
3. A compound of following formula:, wherein:
R1 represents H or a group selected from C1-C6 alkyl, C3-C7 cycloalkyl, C6-C10 aryl, aralkyl and C5-C10-membered heteroaryl groups, said C1-C6 alkyl, C3-C7 cycloalkyl, C6-C10 aryl, aralkyl and C5-C10-membered heteroaryl groups are optionally substituted by at least one Y1 group;
R2 represents a group selected from C6-C10 aryl and C5-C10-membered heteroaryl groups, said C6-C10 aryl and C5-C10-membered heteroaryl groups are optionally substituted by at least one Y2 group;
R3 represents an aralkyl group, said aralkyl group is optionally substituted by at least one Y3 group;
R4 represents H or a group selected from C1-C6 alkyl and C3-C7 cycloalkyl groups, said C1-C6 alkyl and C3-C7 cycloalkyl groups are optionally substituted by at least one Y4 group;
Z represents a prow of following formula:, or an oxazolyl, or an oxadiazolyl;
R, R′, R″ and R′″ each independently represent H or a group selected from:
a C1-C6 alkyl group;
a C3-C7 cycloalkyl group;
an halogen;
a —ORi group;
a —CF3 group;
X represents O or S;
said Y1, Y2, Y3 and Y4, groups are each independently selected from:
a C1-C6 alkyl group;
a C3-C7 cycloalkyl group;
an halogen;
a —ORii group;
Ri and Rii each independently represent H, a C1-C6 alkyl group, a C3-C10 cycloalkyl group or an aralkyl group;
provided that:
when Z═Z1:
at least one of R, R′ and R″ does not represent H; or
when R, R′ and R″ represent H, then R2 represents a group selected from C6-C10 aryl and C5-C10-membered heteroaryl groups substituted by at least an halogen group; or R3 represents a group selected from C6-C10 aralkyl groups substituted by at least an halogen group;

when Z═Z2:
at least one of R, R′, R″ and R′″ does not represent H; or
when R, R′, R″ and R′″ represent H; then R2 represents a group selected from C6-C10 aryl and C5-C10-membered heteroaryl groups substituted by at least a halogen group; or R3 represents a group selected from C6-C10 aralkyl groups substituted by at least an halogen group; or
when R, R′ and R′″ represent H and R″ represents a C1-C6 alkyl group or a —ORi group; then R2 does not represent a 4-HO-phenyl- group; or R3 represents a group selected from C6-C10 aralkyl groups substituted by at least an halogen group,
R5 represents a —C(═O)Ra group or a —C(═O)ORa group, said C(═O)Ra group and —C(═O)ORa group are optionally substituted by at least one Y5 group, wherein Ra represents H, a C1-C6 alkyl group, a C3-C7 cycloalkyl group, a C6-C10 aryl, or an aralkyl group, said C1-C6 alkyl group, C3-C7 cycloalkyl group, C6-C10 aryl, and aralkyl group are optionally substituted by at least one Ya group.
