Synthesis of a new series of 3,4‐diarylpyrazole‐1‐carboxamide derivatives is described. Their antiproliferative activity against A375P human melanoma cell line was tested and the effect of substituents on the diarylpyrazole scaffold was investigated. The biological results indicated that five synthesized compounds (Ig, Ii, IIc, IIg, and IIh) exhibited similar activity to Sorafenib. In addition, three
描述了一系列新的 3,4-二芳基吡唑-1-甲酰胺衍生物的合成。测试了它们对 A375P 人黑色素瘤细胞系的抗增殖活性,并研究了取代基对二芳基吡唑支架的影响。生物学结果表明,五种合成化合物(Ig、Ii、IIc、IIg 和 IIh)表现出与索拉非尼相似的活性。此外,三种化合物(IIa、IIb 和 IIi)比索拉非尼更有效。在所有这些衍生物中,具有二甲氨基和酚部分的化合物 IIa 对 A375P 人黑色素瘤细胞系显示出最有效的抗增殖活性。通过将最有效的化合物 IIa 对接到 V600E-b-Raf 域中进行虚拟筛选,并研究了结合模式。
