The invention provides kinase inhibitors of Formula I:
wherein either:
(1) R1 is H, and
(a) R2 is (3-chlorobenzyl)oxy-and R3 is chloro;
(b) R2 and R3, together with the carbon atoms to which they are attached, form 1-(3-fluorobenzyl)-1H-pyrazole;
(c) R2 is 2-pyridinylmethoxy and R3 is chloro;
(d) R2 and R3 are both chloro;
(e) R2 is chloro and R1 is bromo;
(f) R2 and R3 are both bromo;
(g) R2 is fluoro and R3 is ethynyl;
(h) R2 is chloro and R3 is ethynyl;
(i) R2 is bromo and R3 is ethynyl;
(j) other than when R1 is in the 3-position in combination with R3, in the 4-position, R2 is bromo and R3 is fluoro;
(k) R2 is 2-pyridinylmethoxy and R3 is fluoro; or
(l) R2 is 2-pyridinylmethoxy and R1 is bromo; or
(2) at least one of R1, R2 and R3 is selected from benzyloxy, 3-chlorobenzyloxy and 2-pyridinylmethoxy and when at least one of R1, R2 and R3 is not benzyloxy, 3-chlorobenzyloxy or 2-pyridinylmethoxy, each of the others is independently selected from H, halogen, and C2-C4 alkynyl, with the proviso that when one of R1, R2 and R3 is benzyloxy or 2-pyridinylmethoxy, the other two of R1, R2 and R3 are not H; or
(3) two of R1, R2 and R3, 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 C2-C4 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Formula I的激酶抑制剂:其中要么:(1)R1为H,且(a)R2为(3-氯苯基)氧基且R3为氯;(b)R2和R3与它们附着的碳原子一起形成1-(3-氟苯基)-1H-吡唑;(c)R2为2-吡啶甲氧基且R3为氯;(d)R2和R3均为氯;(e)R2为氯且R1为溴;(f)R2和R3均为溴;(g)R2为氟且R3为乙炔基;(h)R2为氯且R3为乙炔基;(i)R2为溴且R3为乙炔基;(j)当R1与R3相结合时,不在3位,而在4位时,R2为溴且R3为氟;(k)R2为2-吡啶甲氧基且R3为氟;或(l)R2为2-吡啶甲氧基且R1为溴;或(2)至少有一个R1,R2和R3选自苄氧基,3-氯苯甲氧基和2-吡啶甲氧基,当至少有一个R1,R2和R3不是苄氧基,3-氯苯甲氧基或2-吡啶甲氧基时,其他每个都独立地选自H,卤素和C2-C4炔基,但是当R1,R2和R3中有一个是苄氧基或2-吡啶甲氧基时,其他两个不是H;或(3)两个R1,R2和R3与它们附着的碳原子一起形成1-(3-氟苯基)-1H-吡唑;另外还提供了还原型前药,包括定义如上的激酶抑制剂和与激酶抑制剂的氮直接或间接连接的还原性触发剂。还提供了制药组合物,包括激酶抑制剂或前药,以及这种组合物在治疗中的应用,特别是用于治疗癌症。
