The invention provides kinase inhibitors of Formula I:
wherein either:
(1) R
1
is H, and
(a) R
2
is (3-chlorobenzyl)oxy- and R
3
is chloro;
(b) R
2
and R
3
, together with the carbon atoms to which they are attached, form 1-(3-fluorobenzyl)-1H-pyrazole;
(c) R
2
is 2-pyridinylmethoxy and R
3
is chloro;
(d) R
2
and R
3
are both chloro;
(e) R
2
is chloro and R
1
is bromo;
(f) R
2
and R
3
are both bromo;
(g) R
2
is fluoro and R
3
is ethynyl;
(h) R
2
is chloro and R
3
is ethynyl;
(i) R
2
is bromo and R
3
is ethynyl;
(j) other than when R
1
is in the 3-position in combination with R
3
, in the 4-position, R
2
is bromo and R
3
is fluoro;
(k) R
2
is 2-pyridinylmethoxy and R
3
is fluoro; or
(l) R
2
is 2-pyridinylmethoxy and R
1
is bromo; or
(2) at least one of R
1
, R
2
and R
3
is selected from benzyloxy, 3-chlorobenzyloxy and 2-pyridinylmethoxy and when at least one of R
1
, R
2
and R
3
is not benzyloxy, 3-chlorobenzyloxy or 2-pyridinylmethoxy, each of the others is independently selected from H, halogen, and C
2
-C
4
alkynyl, with the proviso that when one of R
1
, R
2
and R
3
is benzyloxy or 2-pyridinylmethoxy, the other two of R
1
, R
2
and R
3
are not H; or
(3) two of R
1
, R
2
and R
3
, together with the carbon atoms to which they are attached, form 1-(3-fluorobenzyl)-1H-pyrazole; and the other is selected from H, halogen and C
2
-C
4
alkynyl.
Also provided are reductive prodrugs, comprising a kinase inhibitor as defined above and a reductive trigger linked directly or indirectly to a nitrogen of the kinase inhibitor. Further provided are pharmaceutical compositions, comprising the kinase inhibitors or the prodrugs, and the use of such compositions in therapy, in particular for treating cancer.
本发明提供了式I的激酶抑制剂:其中:(1) R1为H,且(a) R2为(3-氯苯基)氧基,R3为氯;(b) R2和R3与它们连接的碳原子一起形成1-(3-氟苯基)-1H-吡唑;(c) R2为2-吡啶甲氧基,R3为氯;(d) R2和R3均为氯;(e) R2为氯,R1为溴;(f) R2和R3均为溴;(g) R2为氟,R3为乙炔基;(h) R2为氯,R3为乙炔基;(i) R2为溴,R3为乙炔基;(j) 当R1与R3组合时,R1在3位,R2在4位,R2为溴,R3为氟,除外;(k) R2为2-吡啶甲氧基,R3为氟;或(l) R2为2-吡啶甲氧基,R1为溴;或(2) R1、R2和R3中至少有一个选择自苄氧基、3-氯苯甲氧基和2-吡啶甲氧基,当R1、R2和R3中至少有一个不是苄氧基、3-氯苯甲氧基或2-吡啶甲氧基时,其他每个基团独立选择自H、卤素和C2-C4炔基,但当R1、R2和R3中有一个为苄氧基或2-吡啶甲氧基时,另外两个基团不为H;或(3) R1、R2和R3中的两个与它们连接的碳原子一起形成1-(3-氟苯基)-1H-吡唑;另外一个基团选择自H、卤素和C2-C4炔基。还提供了还原前药,包括定义如上的激酶抑制剂和直接或间接连接到激酶抑制剂的氮上的还原触发剂。还提供了制药组合物,包括激酶抑制剂或前药,以及在治疗中使用这种组合物,特别是用于治疗癌症。
