Patent ID: 7842806

Claim:
A compound corresponding to the formula (I): in which: R1 is selected from the group consisting of: H, (C 1 -C 6 )alkyl, (C 2 -C 6 )alkenyl, (C 2 -C 6 )alkynyl, (C 3 -C 7 )cycloalkyl and (C 3 -C 7 )cycloalkyl (C 1 -C 6 )alkyl; R2 and R3 are independently selected from the group consisting of: H, halogen, (C 1 -C 4 )alkyl, trifluoromethyl and (C 1 -C 4 )alkoxy; Ar 1 represents a radical chosen from: R5 is selected from the group consisting of: H, cyano, hydroxy(C 1 -C 4 )alkyl, (C 1 -C 6 )alkoxy(C 1 -C 4 )alkyl, —(CH 2 ) n NR6R7, —(CH 2 ) m CO 2 R6, —(CH 2 ) m CONHNR6R7, —(CH 2 ) m CONR6R7, —(CH 2 ) m CONR7OR8, —(CH 2 ) n NR6COR7 and —(CH 2 ) n NR6COOR7; R4 is selected from the group consisting of: H, (C 1 -C 4 )alkyl and R5; when Ar 1 takes the value a), then R4 and R5 are not two hydrogen atoms; R6 and R7 are independently selected from the group consisting of: H, (C 1 -C 4 )alkyl, (C 3 -C 7 )cycloalkyl and (C 3 -C 7 )cycloalkyl(C 1 -C 4 )alkyl; R7 can also represent a tert-butoxycarbonyl or benzyloxycarbonyl group; or R6 and R7, together with the nitrogen atom to which they are bonded, constitute an azetidinyl, pyrrolidinyl, piperidinyl, piperazinyl or morpholinyl radical; R8 is selected from the group consisting of: H and (C 1 -C 4 )alkyl; X is O or S; X1 and X2 are independently selected from the group consisting of: H and —(C 1 -C 6 )alkyl-N((C 1 -C 6 )alkyl) 2 ; when one of X1 and X2 is other than H, then X3 is selected from the group consisting of: hydroxyl and (C 1 -C 6 )alkoxy; when X1 and X2 are H, then X3 is selected from the group consisting of: —(CH 2 ) n —CH(NHR9)-CO—R10, —O—(CH 2 ) n —CH(NHR9)-CO—R10 and —NHSO 2 —(C 1 -C 6 )alkyl; R9 is selected from the group consisting of: H, t-butyloxycarbonyl, benzyloxycarbonyl and (C 1 -C 6 )alkyl; R10 is selected from the group consisting of: hydroxyl, (C 1 -C 6 )alkoxy and —NR11R12; R11 and R12 are independently selected from the group consisting of: H and (C 1 -C 6 )alkyl; or R11 and R12, together with the nitrogen atom to which they are bonded, constitute an azetidinyl, pyrrolidinyl, piperidinyl, piperazinyl or morpholinyl radical; m represents 0, 1, 2 or 3; n represents 1, 2 or 3; or a pharmaceutically acceptable salt, hydrate or solvate thereof.
