  Discovery of a potent, selective and orally active canine COX-2 inhibitor, 2-(3-difluoromethyl-5-phenyl-pyrazol-1-yl)-5-methanesulfonyl-pyridine

  摘要：

  Structure-activity relationship (SAR) studies of 2-[3-di(and tri)fluoromethyl-5-arylpyrazol-1-yl]-5-methanesulfonylpyridine derivatives for canine COX enzymes are described. This led to the identification of 12a as a lead candidate for further progression. The in vitro and in vivo activity of 12a for the canine COX-2 enzyme as well as its in vivo efficacy and pharmacokinetic properties in dog are highlighted. (C) 2003 Elsevier Ltd.

  were designed and synthesized for the discovery of compounds with potent herbicidal activity. The compounds were tested for inhibitory activity against the growth of Arabidopsis thaliana roots, and the results demonstrated that the IC50 value of compound V-7 was 45 times lower than that of the halauxifen-methyl commercial herbicide. Molecular docking analyses revealed that compound V-7 docked with the

  吡啶甲酸和吡啶甲酸盐化合物是一类卓越的合成植物生长素除草剂。近年来，两种新的吡啶甲酸酯类化合物甲基卤昔芬（ArylexTM 活性）和氟吡唑醚苄基（RinskorTM 活性）已作为新型除草剂上市。以其结构骨架为模板，设计合成了33个4-amino-3,5-dicholor-6-(5-aryl-substituted-1-pytazolyl)-2-picolinic acid化合物，用于发现具有强效除草作用的化合物活动。测试化合物对拟南芥根部生长的抑制活性，结果表明化合物V-7的IC50值比商业除草剂halauxifen-methyl低45倍。分子对接分析表明，化合物 V-7 与受体生长素信号转导 F-box 蛋白 5 (AFB5) 的对接比毒草胺更密集。根据这些 IC50 值构建自适应三维定量构效关系模型，以指导下一步的合成策略。新化合物的除草试验表明，化合物V-8在300 gha-1剂量下
