With the increasingly acquired resistance, relapse and side effects of known marketed BRAF<sup>V600E<\/sup> inhibitors, it&#8217;s significant to design the more effective and novel drugs. In this study, a series of novel pyrazole derivatives containing acetamide bond had been designed and synthesized on the basis of anal. of the endogenous ligands extracted from the known B-Raf co-crystals in the PDB database. Then, the compounds were evaluated for biol. activities as potential BRAF<sup>V600E<\/sup> inhibitors. The bioassay results in vitro against three human tumor cell lines revealed that some of the compounds showed very impressed antiproliferative property. Among them, the compound <strong>I<\/strong> with IC<sub>50<\/sub> values of 0.10 \u00b1 0.01 \u03bcM against BRAF<sup>V600E<\/sup> and 0.96 \u00b1 0.10 \u03bcM against A375 cell line, showed the most potent inhibitory effect, compared with the pos.-controlled agents vemurafenib (IC<sub>50<\/sub> = 0.04 \u00b1 0.004 \u03bcM for BRAF<sup>V600E<\/sup>, IC<sub>50<\/sub> = 1.05 \u00b1 0.10 \u03bcM against A375). Further investigation confirmed that the compound <strong>I<\/strong> could induce A375 cell apoptosis, induce A375 cell death through changing mitochondrial membrane potential, and result in A375 cell arrest at the G1 phase of the cell cycle. Docking simulations results indicated that the compound 5r could bind tightly at the BRAF<sup>V600E<\/sup> active site. Meanwhile, 3D-QSAR model suggested that these compounds may be potential anticancer inhibitors. Overall, the article provided some new mol. scaffolds for the further BRAF<sup>V600E<\/sup> inhibitors.<\/p>\n<p>2075-46-9, 4-Nitro-1H-pyrazole, also known as 4-Nitropyrazole, is a useful research compound.
