57 There are provided pharmaceutical compositions containing as an active ingredient a compound of the general formula (I):
wherein R1 and R2 are each independently CN, CONH2 or COOH or one of R1 ad R2 may be -CSNH2 or, when R1 is CN, R2 can also be the group
R3 is H, CH3 or OH,
R4, Rs, R6, R7 are each independently H, OH, C1-5 alkyl, C1-5 alkoxy, NH2, CHO, halogen, N02 or COOH, or R4 and R5 together may represent a group -O-CH2-O-;
provided that: (a) when R4 ad R7 are each OH, R3, R5 and R6 are each H and one of R1 and R2 is CN, then the other of R1 and R2 cannot be CONH2; and (b) when R3 and R7 are each H, R5 is OH and R4 and R6 are both H or both C1 -5 alkyl, then R1 is CN and R2 is CN or the group
or a pharmaceutically acceptable salt thereof.
There are also provided some novel compounds of formula (I) above.
The compositions and compounds according to the invention are efficient protein-tyrosine kinase inhibitors and are suitable for the inhibition of proliferative processes in mammalian cells.
57 提供了含有通式(I)化合物作为活性成分的药物组合物:
其中 R1 和 R2 各自独立地为 CN、CONH2 或 COOH,或者 R1 和 R2 中的一个可以是 -CSNH2,或者当 R1 为 CN 时,R2 也可以是基团
R3 是 H、CH3 或 OH、
