The invention relates to compounds of a general formula (I):
wherein Ar
1
is an optionally-substituted aryl or heteroaromatic group; R
1
is an optionally-substituted lower alkyl, lower alkenyl, lower alkynyl or cyclo-lower alkyl group, or is an aryl, aralkyl or heteroaromatic group optionally having a substituent; R
2
is a hydrogen atom, a lower alkyl group, a lower alkenyl group or a lower alkynyl group, or is an aryl, aralkyl or heteroaromatic group optionally having a substituent; R
3
is a hydrogen atom or a lower alkyl group; R
4
is a hydrogen atom, a halogen atom, a hydroxyl group, a lower alkyl group or a group of —N(R
1k
)R
1m
; T and U are a nitrogen atom or a methine group, etc.
The compounds of the invention have excellent Weel kinase-inhibitory effect and are therefore useful in the field of medicines, especially treatment of various cancers.
该发明涉及一般式(I)的化合物,其中Ar1是可选择取代的芳基或杂环芳基;R1是可选择取代的较低烷基、较低烯烃基、较低炔烃基或环状较低烷基基团,或是具有取代基的芳基、芳基烷基或杂环芳基;R2是氢原子、较低烷基基团、较低烯烃基团或较低炔烃基团,或是具有取代基的芳基、芳基烷基或杂环芳基;R3是氢原子或较低烷基基团;R4是氢原子、卤素原子、羟基、较低烷基基团或—N(R1k)R1m基团;T和U是氮原子或亚甲基基团等。该发明的化合物具有出色的Weel激酶抑制作用,因此在药物领域中特别适用于治疗各种癌症。
