The present invention relates to compounds represented by Formula 1
or a pharmaceutically acceptable salt thereof,
wherein:
R1 is chloro or methyl;
R2 is hydrogen or chloro;
R3 is hydrogen, fluoro, chloro, bromo, methyl, ethyl, isopropyl, pentyl, hexyl, octyl, methoxy, phenoxy, (4-nitrophenyl)sulfonyl, piperidin-4-yl, or piperazin-1-yl;
R4 is hydrogen, chloro, methyl or trifluoromethyl, phenoxy, (4-nitrophenyl)sulfonyl or piperidin-4-yl; or
R3 and R4, together with the carbons to which they are attached, form a fused ring selected form the group consisting of:
n is 1 or 2.
These compounds according to the present invention remarkably inhibits activity of DRAK that inhibits signal systems of TGF-β, which is known to suppress cancer growth, and thus the novel pyrimidine compounds can be used as a pharmaceutical composition for preventing or treating cancer and can be used as a pharmaceutical composition for preventing or treating inflammatory disease.
                            本发明涉及由式 1 表示的化合物
或其药学上可接受的盐、
其中
R1 是
氯或甲基
R2 是氢或
氯
R3 是氢、
氟、
氯、
溴、甲基、乙基、异丙基、戊基、己基、辛基、甲氧基、苯氧基、(4-
硝基苯基)磺酰基、
哌啶-4-基或
哌嗪-1-基;
R4 是氢、
氯、甲基或三
氟甲基、苯氧基、(4-
硝基苯基)磺酰基或
哌啶-4-基;或
R3 和 R4,连同它们所连接的碳,形成一个融合环,该环可选自以下组成的组:
n 为 1 或 2。
本发明的这些化合物可显著抑制抑制 TGF-β 信号系统的 DRAK 的活性,众所周知,TGF-β 可抑制癌症生长,因此新型
嘧啶化合物可用作预防或治疗癌症的药物组合物,也可用作预防或治疗炎症性疾病的药物组合物。
