for their antiproliferative activity as dual p38α/BRAFV600E inhibitors. The results revealed that the presence of the carboximidamide moiety is required for activity, and the best activity correlates with the Ar = 1,2-benzodioxole (3e) ≥ 4-CH3O-C6H5-(3c) > 2-naphthyl (3h) > 4-Cl-C6H5 (3b). Ring closure of carboximidamide to 1,2,4-oxadiazole significantly reduces the activity. The results of docking study
最近的研究表明,结合激酶抑制剂具有相加和协同作用。BRAF V600E和 p38α 作为多种疾病的潜在治疗靶点已被广泛研究。为了与我们对开发多靶向抗癌剂的兴趣保持一致,一系列含有 3-芳基-1,2,4-恶二唑部分(4a-h,支架 B)的新型三芳基咪唑类似物及其反应中间体芳基羧酰亚胺部分(3a-h,支架 A)已被合理设计、合成并在体外评估其抗增殖活性作为双重 p38α/BRAF V600E抑制剂。结果表明,活性需要羧亚胺部分的存在,最佳活性与 Ar = 1,2-苯并二氧戊环 ( 3e ) ≥ 4-CH 3 O-C 6 H 5 -( 3c ) > 2-萘基 ( 3h) > 4-Cl-C 6 H 5 ( 3b )。羧酰亚胺酰胺环闭合为 1,2,4-恶二唑会显着降低活性。对 p38α 的对接研究结果表明,与共结晶配体 SB2 相比,化合物3c、3e和 3h具有更高的结合亲和力。然而,化合物3c和3e与BRAF
