  Syntheses of phenylpyrazolodiazepin-7-ones as conformationally rigid analogs of aminopyrazole amide scaffold and their antiproliferative effects on cancer cells

  摘要：

  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.

  摘要：

  由适当的5-氨基吡唑-4-羧酸酯制备1-取代的5-氨基吡唑-4-羰基叠氮化物。酰基叠氮化物经历Curtius重排，然后用醇淬灭以形成相应的氨基甲酸酯。通过催化氢解解封1-取代的5-氨基-4-苄氧基羰基氨基吡唑，得到所需的4，5-二氨基吡唑。立即将这些4，5-二氨基吡唑与乙二醛缩合，得到1-取代的吡唑并[3，4- b ]吡嗪。
