Structure-activityrelationship and crystallographic data revealed that quinazolinone-containing fragments flip between two distinct modes of binding to activin receptor-like kinase-2 (ALK2). We explored both bindingmodes to discover potent inhibitors and characterized the chemical modifications that triggered the flip in bindingmode. We report kinase selectivity and demonstrate that compounds of

The invention relates to chemical compounds of the formula (I): or pharmaceutically acceptable salts thereof, which possess B Raf inhibitory activity and are accordingly useful for their anti cancer activity and thus in methods of treatment of the human or animal body. The invention also relates to processes for the manufacture of said chemical compounds, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments of use in the production of an anti-cancer effect in a warm blooded animal such as man.
series compounds containing hydrophilic group in imidazo[1,2-a]pyridine and quinazolin-4(3H)-one were synthesized and their antiproliferative activities against five cancer cell lines, including HCT-116, SK-HEP-1, MDA-MB-231, SNU638 and A549, were evaluated. Compound 1i with most potent antiproliferative activity was selected for further biological evaluation. PI3K kinase assay showed that 1i has selectivity
磷脂酰肌醇3-激酶(PI3K)是细胞内信号通路的关键调节剂,被认为是癌症治疗方法开发中的有希望的靶标。在不同的PI3K亚型中,编码PI3Kp110α的PIK3CA基因在大多数人类癌症中经常发生突变并过表达。因此,抑制PI3Kα被认为是治疗癌症的有效方法。在这项研究中,合成了在咪唑并[1,2- a ]吡啶和喹唑啉-4(3H)-one中含有亲水基的两个系列化合物,它们对包括HCT-116,SK-HEP-5在内的五种癌细胞系具有抗增殖活性。参照图1,评估了MDA-MB-231,SNU638和A549。化合物1i选择具有最强抗增殖活性的化合物进行进一步的生物学评估。PI3K激酶测定法显示1i对PI3Kα具有选择性,与其他同工型不同。蛋白质印迹分析表明1i在降低磷酸化Akt的水平上比基于咪唑并吡啶的PI3Ka抑制剂HS-173更有效。所有这些结果表明1i是有效的PI3Kα抑制剂,可以被视为开发抗癌药物的潜在候选药物。
