The present invention concerns the compounds of formula (I) the N-oxide forms, the pharmaceutically acceptable addition salts and the stereochemically isomeric forms thereof, wherein a1-a2=a3-a4 represents a divalent radical selected from N-CH=CH-CH, N-CH N-CH or CH-CH=N-CH; Z represents NH; Y represents -C3-9alkyl-, -Cl-5alkyl-NR13-Cl-5alkyl-,-C1-6alkyl-NH-CO- or -CO-NH -C1-6alkyl- ; X1 represents -O- or -NR11-; X2 represents -C1-2alkyl-, -O-C1- 2alkyl, -O- or -O-CH2-;R1 represents hydrogen or halo; R2 represents hydrogen, cyano, halo, hydroxycarbonyl-Cl-4 alkyloxycarbonyl-, Het16-carbonyl- or Ar5; R3 represents hydrogen; R4 represents hydroxy, C1-4alkyloxy-, Ar4-C1-4alkyloxy or R4 represents Cl-4alkyloxy substituted with one or where possible two or more substituents selected from C1-4alkyloxy- or Het2-; R11 represents hydrogen; R12 represents hydrogen, Cl-4alkyl- or Cl-4alkyl-oxy-carbonyl-; R13represents Het14-Cl-4alkyl, in particular morpholinyl-Cl-4alkyl; Het2 represents a heterocycle selected from morpholinyl or piperidinyl optionally substituted with C1-4alkyl-, preferably methyl; Het14 represents morpholinyl; Het16 represents a heterocycle selected from morpholinyl or pyrrolidinyl; Ar4 represents phenyl; Ar5 represents phenyl optionally substituted with cyano.

La présente invention concerne des composés représentés par la formule générale (I), certaines de leurs formes <I>N</I>-oxydes, certains de leurs sels d'addition pharmaceutiquement admis, et certaines de leurs formes stéréochimiquement isomères. Dans cette formule, a?1¿-a?2¿=a?3¿-a?4¿ est un radical divalent choisi parmi N-CH=CH-CH, N-CH N-CH et CH-CH=N-CH. Z est NH. Y est -C¿3-9?alkyl-, -C¿l-5?alkyl-NR?13¿-C¿l-5?alkyl-, -C¿1?-¿6?alkyl-NH-CO- ou -CO-NH -C¿1-6?alkyl-. X?1¿ est -O- ou -NR?11¿-. X?2¿ est -C¿1-2?alkyl-, -O-C¿1-2?alkyle, -O- ou -O-CH¿2?-. R?1¿ est hydrogène ou halo. R?2¿ est hydrogène, cyano, halo, hydroxycarbonyl-C¿l-4 ?alkyloxycarbonyl-, Het?16¿-carbonyl- ou Ar?5¿. R?3¿ est hydrogène. R?4¿ est hydroxy, C¿1-4?alkyloxy-, Ar?4¿-C¿1-4?alkyloxy, ou encore, R?4¿ est C¿1-4?alkyloxy substitué par un, mais dès que possible par plusieurs substituants choisi parmi les C¿1-4?alkyloxy- ou Het?2¿-. R?11¿ est hydrogène. R?12¿ est hydrogène, C¿l-4?alkyl- ou C¿l-4?alkyl-oxy-carbonyl-. R?13¿ est Het?14¿-C¿l-4?alkyle, et particulièrement morpholinyl-C¿l-4?alkyle. Het?2¿ est un hétérocycle choisi parmi les morpholinyle ou pipéridinyle éventuellement substitués par C¿1-4?alkyl-, de préférence méthyle. Het?14¿ est morpholinyle. Het?16¿ est hétérocycle choisi parmi les morpholinyle ou pyrrolidinyle. Ar?4¿ est phényle. Ar?5¿ est phényle éventiellement substitué âr cyano.
