The invention relates to new triazines (G = Q = U are N), pyrimidines (two out of G, Q and U are N), and pyridopyrimidines (one of G and U together with R2 forms an anullated pyridine ring) of formula (I) carrying a spirocyclic substituent, wherein E1 is CR4 or N; X1 is CHR4, CH2CH2, NR4, 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.
本发明涉及新的三嗪类化合物(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共同形成一个环状
吡啶环),它们都带有一个螺环取代基,
化学式为(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所定义。这些化合物能够抑制
磷脂酰肌醇3-激酶(
PI3K)、哺乳动物
雷帕霉素靶
蛋白酶(mTOR)、DNA-PK和ATM激酶,并可用作治疗剂或诊断探针。本发明还涉及使用这些化合物治疗相关病理条件的方法。
