, NR4→0, or O; and the other substituents are as defined in the specification. The compounds inhibit phosphoinositide 3-kinase (PI3K), mammalian target of rapamycin (mTOR), DNA-PK and ATM kinase, and may be used as therapeutic agents or diagnostic probes. The invention also relates to methods of using the compounds for treatment of associated pathological conditions.
该发明涉及具有螺环取代基的新三嗪类化合物(其中G=Q=U为N)、
嘧啶类化合物(其中G、Q和U中的两个为N)和
吡啶嘧啶类化合物(其中G和U中的一个与R2一起形成一个环状
吡啶环)的
化学式(I),其中E1为CR4或N;X1为CHR4、CH2CH2、NR4、NR4→0或O;其他取代基如规范中定义。这些化合物抑制
