Patent ID: 7329660

Claim:
A method of treating leukemias by inhibiting VEGF-receptor tyrosine kinase activity comprising administering a compound of formula I, wherein r is 0 to 2, n is 0 to 3 R 1 and R 2 a) are independently in each case a lower alkyl; b) together form a bridge of subformula I*, wherein a bond characterizing said bridge is achieved via two terminal C atoms of R 1 and R 2 and m is 0 to 4, or c) together form a bridge of subformula I**, wherein one or two of the ring members T 1 , T 2 , T 3 and T 4 are nitrogen, and the others are in each case CH, and the bond is achieved via atoms T 1 and T 4 ; G is —C(═O)—, —CHF—, —CF 2 —, lower alkylene, C 2 -C 6 alkenylene, lower alkylene or C 3 -C 6 alkenylene substituted by acyloxy or hydroxy, —CH 2 —O—, —CH 2 —S—, —CH 2 —NH—, —CH 2 —O—CH 2 —, —CH 2 —S—CH 2 —, oxa (—O—), thia (—S—), imino (—NH—), or —CH 2 —NH—CH 2 —; A, B, D, E and T are independently N or CH subject to the proviso that at least one and not more than three of these radicals are N; Q is lower alkyl, lower alkoxy, or halogen; R a and R a ′ are each independently H or lower alkyl; X is imino, oxa or thia; Y is hydrogen, aryl, heteroaryl, or unsubstituted or substituted cycloalkyl; and Z is mono- or disubstituted amino, halogen, alkyl, substituted alkyl, hydroxy, etherified or esterified hydroxy, nitro, cyano, carboxy, esterified carboxy, alkanoyl, carbamoyl, N- mono- or N,N-disubstituted carbamoyl, amidino, guanidino, mercapto, sulfo, phenylthio, phenyl lower alkylthio, alkylphenylthio, phenylsulfinyl, phenyl-lower alkylsulfinyl, alkylphenylsulfinyl, phenylsulfonyl, phenyl-lower alkylsulfonyl, alkylphenylsulfonyl, or selected from the group consisting of ureido, halo-lower alkylthio, halo-lower alkansulfonyl, pyrazolyl, lower-alkyl pyrazolyl and C 2 -C 7 alkenyl; wherein—if more than 1 radical Z(m≧2) is present—the substituents Z are selected independently from each other; and wherein the bonds characterized in subformula I* by a wavy line are either single or double bonds; or an N-oxide of said compound, wherein 1 or more N atoms carry an oxygen atom; or a pharmaceutically acceptable salt thereof.
