alkyl), and R
9
is hydrogen, optionally substituted hydrocarbyl, optionally substituted heterocyclyl or optionally substituted alkoxy); provided that at least one of R

Thus they, and pharmaceutical compositions containing them, are useful in methods of treatment of proliferative disease such as cancer and in particular cancers such as colorectal or breast cancer where aurora 2 is upregulated.
化合物的公式(I)1或其盐、酯、酰胺或前药;其中R5是一个含有至少一个氮原子的可选取代的6成员芳香环,而R1、R2、R3、R4是独立选择的卤素基、氰基、硝基、C1-3烷基磺酰基、-N(OH)R7-(其中R7是氢或C1-3烷基)或R9X1-(其中X1表示直接键,-O-,-CH2-,-OC(O)-,-C(O)-,-S-,-SO-,-SO2-,-NR10C(O)-,-C(O)NR11-,-SO2NR12-,-NR13SO2-或-NR14-(其中R10、R11、R12、R13和R14各自独立地表示氢、C1-3烷基或C1-3烷氧基C2-3烷基),而R9是氢、可选取代的烃基、可选取代的杂环基或可选取代的烷氧基;前提是R2或R3至少有一个不是氢。这些化合物是aurora 2激酶的抑制剂。因此,它们及包含它们的药物组成物在治疗增殖性疾病如癌症以及特别是aurora 2上调的结直肠癌或乳腺癌的方法中是有用的。
