  摘要：

  描述了一系列新的 3,4-二芳基吡唑-1-甲酰胺衍生物的合成。测试了它们对 A375P 人黑色素瘤细胞系的抗增殖活性，并研究了取代基对二芳基吡唑支架的影响。生物学结果表明，五种合成化合物（Ig、Ii、IIc、IIg 和 IIh）表现出与索拉非尼相似的活性。此外，三种化合物（IIa、IIb 和 IIi）比索拉非尼更有效。在所有这些衍生物中，具有二甲氨基和酚部分的化合物 IIa 对 A375P 人黑色素瘤细胞系显示出最有效的抗增殖活性。通过将最有效的化合物 IIa 对接到 V600E-b-Raf 域中进行虚拟筛选，并研究了结合模式。

  A series of thirteen triarylpyrazole analogs were investigated as inhibitors of lipopolysaccharide (LPS)-induced prostaglandin E2 (PGE2) and nitric oxide (NO) production in RAW 264.7 macrophages. The target compounds 1a–m have first been assessed for cytotoxicity against RAW 264.7 macrophages to determine their non-cytotoxic concentration(s) for anti-inflammatory testing to make sure that the inhibition of PGE2 and NO production would not be caused by cytotoxicity. It was found that compounds 1f and 1m were the most potent PGE2 inhibitors with IC50 values of 7.1 and 1.1 μM, respectively. In addition, these compounds also showed inhibitory effects of 11.6% and 37.19% on LPS-induced NO production, respectively. The western blots analysis of COX-2 and iNOS showed that the PGE2 and NO inhibitory effect of compound 1m are attributed to inhibition of COX-2 and iNOS protein expression through inactivation of p38.

  一系列十三个三芳基吡唑类似物被研究作为抑制RAW 264.7巨噬细胞中脂多糖（LPS）诱导的前列腺素E2（PGE2）和一氧化氮（NO）产生的抑制剂。首先评估了目标化合物1a-m对RAW 264.7巨噬细胞的细胞毒性，以确定它们的非细胞毒浓度，用于抗炎测试，以确保PGE2和NO产生的抑制不是由细胞毒性引起的。发现化合物1f和1m是最有效的PGE2抑制剂，IC50值分别为7.1和1.1μM。此外，这些化合物还分别显示对LPS诱导的NO产生的抑制效果为11.6%和37.19%。COX-2和iNOS的免疫印迹分析显示，化合物1m的PGE2和NO抑制效应归因于通过抑制p38使COX-2和iNOS蛋白表达失活。

  Synthesis of a new series of diarylureas and diarylamides possessing 1,3,4-triarylpyrazole scaffold is described. Their in vitro antiproliferative activities against 9 human melanoma cell lines were tested. Compounds 12, 13, 15, and 21-23 showed the highest potency against A375P melanoma cell line. In addition, compounds 10-15 and 19-24 showed high potency over the NCl 8 tested melanoma cell-lines panel. The IC50 values for compound 23 were 0.36 mu M and 0.84 mu M over LOX IMVI and M14 cell lines, respectively. Compounds 21 and 23 showed high, dose-dependent inhibition of ERK kinase. Virtual screening was carried out through docking of compound 21 into the domain of V600E-B-RAF and the binding mode was studied. (C) 2011 Elsevier Masson SAS. All rights reserved.
• Antiproliferative Diarylpyrazole Derivatives as Dual Inhibitors of the ERK Pathway and COX-2

  日期：2013.9

  A series of 3,4‐diarylpyrazole‐1‐carboxamide derivatives was designed and synthesized. A selected group of the target compounds was tested for in vitro antiproliferative activities over a panel of 60 cancer cell lines at the National Cancer Institute (NCI, Bethesda, MD, USA) at a single‐dose concentration of 10 μm, and the four most active compounds 9a, 9l, 9n, and 10o were further tested in a five‐dose testing mode to determine their IC50 values over the 60 cell lines. In addition, a selected group of target compounds were tested for inhibitory effect over cyclooxygenase isozymes. Compounds 9a, 9l, 9n, and 10o were also tested for MEK and ERK kinase inhibitory activity using Western blot assay. Compound 10o was selective toward melanoma cell line subpanel, and its antiproliferative activity may be attributed to selective cyclooxygenase‐2 inhibition and ERK pathway inhibition.

  A new series of diarylureas and diarylamides possessing 1,3,4-triarylpyrazole scaffold was designed and synthesized. Their in vitro antiproliferative activities against NCI-60 cell line panel were tested. Most of the compounds showed strong and broad-spectrum antiproliferative activities. Compound 18 exerted sub-micromolar IC50 values over all the subpanels of nine different cancer types. Its IC50 value over MDA-MB-435 melanoma cell line was 27 nM. Compounds 10-13, 22, and 23 possessing urea spacer exerted lethal effect over the NCI-60 panel with mean %inhibitions more than 100% in single-dose testing. Compounds 13 and 23 with urea linker and 3',5'-bis(trifluoromethyl)phenyl terminal ring showed the highest mean %inhibition over the NCI-60 panel in single-dose testing, and showed high potencies and broad-spectrum anticancer activities in five-dose testing.
