Design and Synthesis of Indomethacin Analogues That Inhibit P-Glycoprotein and/or Multidrug Resistant Protein without Cox Inhibitory Activity
摘要:
We designed and synthesized conformationally restricted analogues and regioisomers of the nonsteroidal anti-inflammatory drug indomethacin. Evaluation of the inhibitory effects of these compounds on COX, P-glycoprotein, and multidrug resistance indicated that NSAIDS modulation of multidrug-resistant P-glycoprotein and multidrug-resistant protein-1 is not associated with COX-1 and COX-2 inhibitory activities.
第二代Grubbs钌催化剂与乙烯基氧基三甲基硅烷的反应可有效生成具有N-杂环卡宾(NHC)配体的纯氢化钌络合物,并具有明确的特征。该氢化钌络合物对末端烯烃的选择性异构化和1,6-二烯的环异构化显示出高催化活性。的这些反应Ñ -allyl- Ò -vinylaniline导致新的合成方法杂环如吲哚和3-亚甲基-2,3- dihydroindoles,这对于生物活性天然产物有用的合成子。这些程序解决了面向多样性的综合中的一个重要问题。
