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 and R₂ may be -CSNH₂ or, when R₁ is CN, R₂ can also be the group
R₃ is H, CH₃ or OH,
R₄, R₅, R₆, R₇ are each independently H, OH, C₁₋₅ alkyl, C₁₋₅ alkoxy. NH₂, CHO, halogen, NO₂ or COOH, or R₄ and R₅ together may represent a group -O-CH₂-O-;
provided that: (a) when R₄ and 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.
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 是 CN 时,R₂ 也可以是基团
R₃ 是 H、CH₃ 或 OH、
R₄、R₅、R₆、R₇各自独立地为 H、OH、C₁₋₅烷基、C₁₋₅烷氧基。NH₂、CHO、卤素、NO₂或 COOH,或 R₄ 和 R₅ 可共同代表一个基团 -O-CH₂-O-;
条件是(a) 当 R₄ 和 R₇ 均为 OH,R₃、R₅ 和 R₆ 均为 H,且 R₁ 和 R₂ 中的一个为 CN 时,则 R₁ 和 R₂ 中的另一个不能为 CONH₂;(b) 当 R₃ 和 R₇ 分别为 H、R₅ 为 OH 且 R₄ 和 R₆ 均为 H 或均为 C₁₋₅ 烷基时,则 R₁ 为 CN,R₂ 为 CN 或基团
或其药学上可接受的盐。
还提供了一些上述式 (I) 的新型化合物。
根据本发明的组合物和化合物是高效的蛋白酪氨酸激酶抑制剂,适用于抑制哺乳动物细胞的增殖过程。
