  Synthesis and Biological Evaluation of New 1,2-Dihydro-4-hydroxy-2-oxo-3-quinolinecarboxamides for Treatment of Autoimmune Disorders:  Structure−Activity Relationship

  摘要：

  Roquinimex-related 3-quinolinecarboxamide derivatives were prepared and evaluated for treatment of autoimmune disorders. The compounds were tested in mice for their inhibitory effects on disease development in the acute experimental autoimmune encephalomyelitis model and selected compounds in the beagle dog for induction of proinflammatory reaction. Structure-activity relationships are discussed. Compound 8c, laquinimod, showed improved potency and superior toxicological profile compared to the lead compound roquinimex (1b, Linomide) and was selected for clinical studies (currently in phase II).

  吴茱萸碱衍生物作为有效杀虫剂候选物的发现

  摘要：

  在寻找新型更有效的杀虫剂时，天然产物具有良好的环境相容性、多种生物活性、独特的支架和作用方式，可作为理想的模板化合物。我们发现吴茱萸果实的主要活性成分天然产物吴茱萸碱对鳞翅目具有明显的杀虫活性。害虫。为了继续我们的研究，我们合理设计和合成了一系列吴茱萸碱衍生物3a-3aa。杀幼虫活性结果表明，大部分目标化合物对Mythimna separata、Plutella xylostella和Helicoverpa armigera的效果优于吴茱萸碱、苦参碱和鱼藤酮，其中3z表现出优异的杀幼虫活性（2.5 mg/L对M. separata的杀幼虫活性为65%， 75% 1.0 mg/L 对P. xylostella和 85% 10 mg/L 对H. armigera，分别），远优于吴茱萸碱（0%）、苦参碱（0%）和鱼藤酮（0%）。初步构效关系表明吴茱萸碱E环上的氟原子对杀幼虫活性有正向影响。钙显像
