Azaindoles.

The invention is directed to compositions containing physiologically active compounds of general formula (I) wherein R1 is aryl or heteroaryl: R2 represent hydrogen, acyl, cyano, halo, lower alkenyl or lower alkyl optionally substituted by a substituent selected from cyano, heteroaryl, heterocycloalkyl, -Z1R8,-C(=O)-NY3Y4,-CO2R8,-NY3Y4,-N(R6)-C(=O)-R7, -N(R6)-C(=O)-NY3Y4,-N(R6)-C(=O)-OR7,-N(R6)-SO2-R7,-N(R6)-SO2-NY3Y4 and one or more halogen atoms; R3 represents hydrogen, aryl, cyno, halo, heteroaryl, lower alkyl,-C(=O)-OR5 or -C(=O)-NY3Y; and X1 represents N.CH. C-halo, C-CN,C-R7,C-NY3Y4,C-OH, C-Z2R7, C-C(=O)-OR5, C-C(=O)-NY3Y4, C-N(R8)-C(=0)-R7,C-SO2-NY3Y4,C-N(R8)-SO2-R7,C-alkenyl or C-NO2; and their prodrugs, and pharmaceutically acceptable salts and solvates of such compounds and their prodrugs, as well as to novel compounds within the scope of formula (I). Such compounds and compositions have valuable pharmaceutical properties, in particular the ability to inhibit protein kinases.
