(3H)-one derivatives were designed, synthesized, and evaluated as Aurora A kinase inhibitors. The cell-based cytotoxicity assays showed that compound 16h was the most potent cytotoxic agent against all tested cancer cells and had a lower IC50 value than ENMD-2076 against MDA-MB-231 cells. Meanwhile, Aurora A kinase assay and Western blot analysis showed that 16h inhibited Aurora A kinase with an IC50
作为Aurora激酶家族成员的Aurora A激酶在各种人类癌症中经常过表达。此外,在包括乳腺癌在内的许多癌症中,Aurora A激酶的过度表达与耐药性和预后不良有关。因此,极光A激酶被认为是治疗人类癌症的有吸引力的抗癌靶标。在此,设计,合成了一系列6-(2-氨基-1H-苯并[d]咪唑-6-基)喹唑啉-4(3H)-衍生物,并将其评估为Aurora A激酶抑制剂。基于细胞的细胞毒性测定表明,化合物16h是对所有测试癌细胞的最有效的细胞毒性剂,并且对MDA-MB-231细胞的IC50值低于ENMD-2076。同时,Aurora A激酶测定和蛋白质印迹分析表明16h抑制Aurora A激酶,IC50值为21。94 nM并抑制了Ser10上的组蛋白H3和Thr288上的Aurora A激酶的磷酸化,这与Aurora A激酶的激活一致。因此,16h在MDA-MB-231细胞中引起异常的有丝分裂表型和明显的G2
