of the diseases can exert superior biological benefits for treatment of these diseases. In the present work, a new series of (imidazol-5-yl)pyrimidine was designed and synthesized as dual inhibitors of BRAFV600E and p38α kinases which are considered as key regulators in mitogen-activated protein kinase (MAPK) signalling pathway. The target compounds were evaluated for dual kinase inhibitory activity
涉及疾病的相同信号传导途径的丝氨酸/苏氨酸蛋白激酶的双重抑制的协同作用可以为治疗这些疾病发挥优越的生物学益处。在本工作中,设计并合成了一系列新的(imidazol-5-yl)嘧啶,作为BRAF V600E和p38α激酶的双重抑制剂,它们被认为是促分裂原活化蛋白激酶(MAPK)信号通路中的关键调节剂。评价目标化合物的双重激酶抑制活性。所测试的化合物相对于BRAF V600E表现出纳摩尔级的IC 50值,相对于p38α表现出低至亚微摩尔级的IC 50范围。化合物20h被确定为最有效的双重BRAFV600E /p38α抑制剂,IC 50值分别为2.49和85 nM。进一步的深入研究表明,化合物20h在脂多糖诱导的RAW 264.7巨噬细胞中具有TNF-α的抑制活性,IC 50值为96.3 nM。此外,目标化合物有效地挫败了LOX-IMVI黑色素瘤细胞系的增殖。化合物20h表现出令人满意的抗增殖活性,IC
