Aiming to explore novel BRAFV600E and VEGFR-2 dual inhibitors, a series of 1H-pyrazolo[3,4-d]pyrimidine derivatives were designed, synthesized and biologically evaluated in this study. Most of the synthesized 1H-pyrazolo[3,4-d]pyrimidine compounds displayed moderate to high potent activity in both enzymatic and cellular proliferation assays. Among these compounds, 9e, 9g, 9m and 9u showed remarkably
为了探索新型的BRAF V600E和VEGFR-2双重抑制剂,在本研究中设计,合成了一系列1 H-吡唑并[3,4-d]嘧啶衍生物。在酶促和细胞增殖试验中,大多数合成的1 H-吡唑并[3,4-d]嘧啶化合物均显示中等至高强度的活性。在这些化合物中,与阳性对照索拉非尼相比,9e,9g,9m和9u表现出对BRAF V600E和VEGFR-2激酶的显着高抑制活性。特别地,化合物9u还显示出对BRAF的有效抗增殖活性表达V600E的A375(IC 50 = 1.74μM)和H-29(IC 50 = 6.92μM)以及表达VEGFR-2的HUVEC(IC 50 = 5.89μM),也可与索拉非尼媲美。此外,激酶选择性谱显示9u对野生型BRAF和15种其他测试的蛋白激酶几乎没有或没有明显的抑制活性。流式细胞仪分析表明,化合物9u主要在G 0 / G 1期阻滞了A375和HUVEC细胞系,并具有浓度
