activities of these compounds on PI3Kα and two tumor cell lines in vitro (HCT-116, U87-MG) were evaluated. The representative compound 13 showed a half-maximal inhibitory concentration (IC50) value of 1.2 nM for PI3Kα and an exciting kinase selectivity. Compound 13 displayed strong efficacy in HCT-116 and U87-MG cell lines with IC50 values of 0.83 and 1.25 μM, respectively. In addition, compound 13 induced
最近的研究表明,磷酸肌醇3激酶(PI3K)在细胞分裂中发挥着至关重要的作用,它已成为许多癌症的治疗靶点。本文以先前有效的化合物2-(二氟甲基)-1-[4,6-二( 4-吗啉基)-1,3,5-三嗪-2-基] -1H-苯并咪唑( ZSTK-474) ,以获得尚未文献报道的有效选择性PI3Kα抑制剂。此外,还评估了这些化合物对 PI3Kα 和两种肿瘤细胞系(HCT-116、U87-MG)的体外抑制活性。代表性化合物13对PI3Kα表现出1.2nM的半数最大抑制浓度(IC 50 )值和令人兴奋的激酶选择性。化合物13在HCT-116和U87-MG细胞系中表现出强大的功效,IC 50值分别为0.83和1.25 μM。此外,化合物13在U87-MG细胞系异种移植小鼠模型中诱导明显的肿瘤消退,以40 mg/kg的剂量腹腔注射后没有明显的毒性迹象。化合物13可以是PI3Kα的有效选择性抑制剂,它为患者提供
