The new use of a compound of formula (I) <IMAGE> (I) wherein Y is a bicyclic ring selected from naphthalene, tetralin, quinoline, isoquinoline and indole; n is zero or an integer of 1 to 3; R1 is hydrogen, C1-C6 alkyl or C2-C6 alkanoyl; R2is hydrogen, halogen, C1-C6 alkyl, cyano, carboxy, nitro, or NHR, wherein R is hydrogen or C1-C6 alkyl; R3 is hydrogen or C1-C6 alkyl; R4 is hydrogen, hydroxy, C1-C6 alkoxy, C2-C6 alkanoyloxy, carboxy, nitro or NHR, wherein R is as defined above; R5 is hydrogen, C1-C6 alkyl or halogen; or a pharmaceutically acceptable salt thereof; and wherein when Y is naphthalene then n is zero or an integer of 1 to 3, whereas when Y is tetralin, quinoline, isoquinoline or indole then n is zero, 1 or 2; and wherein when the bicyclic ring Y is naphthalene, quinoline, isoquinoline or indole, then each of the substituents OR1, R2 and oxindolylidene may be independently on either of the aryl or heteroaryl moieties of said bicyclic ring, whereas only the benzene moiety is substituted when Y is tetralin; and wherein when Y is naphthalene, tetralin, quinoline or isoquinoline, then R2 is hydrogen, halogen, cyano or C1-C6 alkyl and R3, R4 and R5 are hydrogen; whereas when Y is indole, then R2 is hydrogen, halogen, C1-C6 alkyl, cyano, carboxy, nitro or -NHR, in which R is as defined above, R3 is hydrogen or C1-C6 alkyl, R4 is hydrogen, hydroxy, C1-C6 alkoxy, C1-C6 alkanoyloxy, carboxy, nitro or -NHR, wherein R is as defined above, and R5 is hydrogen, halogen or C1-C6 alkyl; as anti-angiogenic agent is disclosed. |
