A series of bis-arylurea and bis-arylamide derivatives based on 1H-benzo[d]imidazole moiety were designed,
synthesized and evaluated as DFG-out B-RafV600E/VEGFR2 dual inhibitors. Compound 4a as the most potent compound
displayed potential dual kinase inhibitory activities against B-RafV600E and VEGFR2 with IC50 values of 57.8 nM and 0.48
μM, as well as effective cellular antiproliferative potencies against A375 and HUVEC with IC50 values of 3.62 µM and
12.46 µM. 4a was also progressed to in vivo profiling, which exhibited similarly equivalent tumor growth inhibition (T/C
= 17.99%) in human melanoma A375 (B-RafV600E) xenograft model by contrast to Sorafenib (T/C = 16.49%) without
body weight loss.
研究人员设计、合成了一系列基于 1H-苯并[d]咪唑的双芳基脲和双芳基酰胺衍生物,并将其作为 DFG-out B-RafV600E/VEGFR2 双抑制剂进行了评估。化合物 4a 是最有效的化合物,对 B-RafV600E 和 VEGFR2 具有潜在的双重激酶抑制活性,IC50 值分别为 57.8 nM 和 0.48 μM,对 A375 和 HUVEC 也具有有效的细胞抗增殖活性,IC50 值分别为 3.62 µM 和 12.46 µM。4a 还进行了体内分析,在人黑色素瘤 A375(B-RafV600E)异种移植模型中显示出与索拉非尼(T/C = 16.49%)类似的肿瘤生长抑制作用(T/C = 17.99%),且无体重减轻。
