that are potent inhibitors of the class of enzymes known as cyclin dependent kinases, which relate to the catalytic subunits cyclin dependent kinase 1-8 and their regulatory subunits know as cyclins A-H, K, N, and T.
This invention also provides a novel method of treating cancer or other proliferative diseases by administering a therapeutically effective amount of one of these compounds or a pharmaceutically acceptable salt form thereof. Alternatively, one can treat cancer or other proliferative diseases by administering a therapeutically effective combination of one of the compounds of the present invention and one or more other known anti-cancer or anti-proliferative agents.
本发明涉及合成一类新型吡唑并[3,4-d]嘧啶-4-酮的化合物,其化学式为(I),或者以互变异构体(II)表示:

这些化合物是强效的cyclin依赖激酶抑制剂,与被称为cyclin依赖激酶1-8的催化亚基及其调节亚基cyclin A-H、K、N和T有关。
本发明还提供了一种新的治疗癌症或其他增殖性疾病的方法,通过给予这些化合物之一或其药用可接受的盐形式的治疗有效剂量。另外,可以通过给予本发明化合物之一与一个或多个其他已知的抗癌或抗增殖剂的治疗有效组合来治疗癌症或其他增殖性疾病。
