The synthesis of a novel series of N-(5-amino-1-(4-methoxybenzyl)-1H- pyrazol-4-yl amide derivatives 6a-o, 7a-s and their antiproliferative activities against A375P melanoma cell line were described. Most compounds showed competitive antiproliferative activities to sorafenib, the reference standard. Among them, N-(5-amino-1-(4-methoxybenzyl)-1H-pyrazol-4-yl)-5-(3-(4-chloro-3- (trifluoromethyl)phenyl) ureido)-2-methylbenzamide 7c exhibited potent activities (GI50 = 0.27 μM). Especially, 7c was found to be a potent and selective B-Raf V600E and C-Raf inhibitor (IC50 = 0.26 μM, IC50 = 0.11 μM, respectively), showing a possibility as melanoma therapeutics.
