CA 2542007

The present invention relates to uses of the compounds of Formula I as well as pharmaceutically acceptable salts and stereoisomers thereof in methods to treat a variety of tumors in mammals involving abnormal tyrosine kinase signalling, the compounds represented as: wherein R1 and R2 are independently selected from the group consisting of H; alkyl; alkenyl; alkynyl; halogen; aryl; heteroaryl containing N, O, or S; the aryl and heteroaryl may be further substituted with halogen, an alkyl, alkenyl, and alkynyl; NZ1Z2, wherein Z1 and Z2 are independently selected from the group consisting of H and alkyl; and (CO)Y wherein Y is selected from the group consisting of H, alkyl, alkenyl, alkynyl, aryl, heteroaryl containing N, O, or S, and the aryl and heteroaryl may be further substituted with halogen, alkyl, alkenyl, and alkynyl; with the proviso that when R1 is hydrogen, R2 is a group other than hydrogen.

La présente invention concerne les utilisations des composés de formule I et de sels et stéréoisomères de ceux-ci, acceptables d'un point de vue pharmaceutique, dans des procédés pour traiter chez des mammifères différentes tumeurs liées à la signalisation anormale de la tyrosine kinase. Dans ladite formule, R¿1? et R¿2? sont choisis indépendamment dans le groupe qui comprend H, alkyle, alcényle, alcynyle, halogène, aryle, hétéroaryle contenant N, O, ou S, aryle et hétéroaryle pouvant être substitués avec halogène, alkyle, alcényle, et alcynyle, NZ¿1?Z¿2? où Z¿1? et Z¿2? sont choisis indépendamment dans le groupe comprenant H et alkyle, et (CO)Y où Y est choisi dans le groupe comprenant H, alkyle, alcényle, alcynyle, aryle, hétéroaryle contenant N, O, ou S, aryle et hétéroaryle pouvant être substitué avec halogène, alkyle, alcényle, et alcynyle, à la condition que lorsque R¿1? est hydrogène, R¿2? est un groupe différent d'hydrogène.
