  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
