  Structure based design and syntheses of amino-1H-pyrazole amide derivatives as selective Raf kinase inhibitors in melanoma cells

  摘要：

  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 (GI(50) = 0.27 mu M). Especially, 7c was found to be a potent and selective B-Raf V600E and C-Raf inhibitor (IC50 = 0.26 mu M, IC50 = 0.11 mu M, respectively), showing a possibility as melanoma therapeutics.

  Recently, we have reported the syntheses and antiproliferative activities of N-(5-amino-1-(4-methoxybenzyl)-1H-pyrazol-4-yl amide derivatives on melanoma cells. As a continuous work for antiproliferative agents in melanoma, here we report the synthesis of conformationally rigid analogs, phenyl-6,8-dihydropyrazolo[3,4-b][1,4] diazepin-7(1H)-one derivatives7a-g, 8a-o and their antiproliferative activities against A375P melanoma cell line and U937 hematopoietic cell line. Most compounds showed competitive antiproliferative activities to sorafenib, the reference standard. Among them, N-(3-(1-benzyl-7-oxo-1,6, 7,8-tetrahydropyrazolo[3,4-b][1,4]diazepin-5-yl)phenyl)-4-chloro-3-(trifluoro methyl)benzamide-amino1-(4-methoxybenzyl)-1H-pyrazol-4-yl)-5-(3-(4-chloro-3-(trifluoromethyl) phenyl) ureido)-2-methylbenzamide (7b) exhibited potent activities (GI(50) = 0.43 mu M and 0.06 mu M) on both cell lines. It has been further confirmed to be a potent and selective Raf kinases inhibitor and also mild inhibitor of PI3K alpha. (C) 2011 Elsevier Ltd. All rights reserved.

  The synthesis of a novel series of 1,4-dihydropyrazolo[4,3-d]imidazole phenyl derivatives 1a-b, 2a-v and their antiproliferative activities against A375P and WM3629 human melanoma cell line were described. Most compounds showed competitive antiproliferative activities to sorafenib, the reference standard. Among them, pyrazoloimidazole phenyl urea compounds 2a, 2d, 2g, 2i, 2t exhibited potent activities on WM3629 cell lines (IC50 = 0.56-0.86 mu M). Especially, 2t was found to be a potent and selective C-Raf inhibitor, showing a possibility as melanoma therapeutics. (C) 2010 Elsevier Ltd. All rights reserved.
