  Simple route to 3-(2-indolyl)-1-propanones via a furan recyclization reaction

  摘要：

  A simple route to 1-R-3-(2-indolyl)-1-propanones has been elaborated based on recyclization of 2-(2-aminobenzyl)furan derivatives. Being a modification of the Reissert indole synthesis, our approach employs the furan ring as a source of carbonyl function. This approach is general and allows varying of substituents in aromatic ring as well as in 3-position of indole nucleus. (c) 2006 Elsevier Ltd. All rights reserved.

  In the course of our study aimed at developing new types of DMARDs (disease-modifying antirheumatic drugs), we found that quinoline derivative 1a had a potent anti-inflammatory effect in an adjuvant arthritis (AA) rat model, starting from the potent bone resorption inhibitors justicidins as the lead compounds. Further modification of la was performed, and various quinoline and quinazoline derivatives having a heteroaryl moiety on the alkyl side chain at the 2-position of the skeleton were prepared. These compounds were evaluated for antiinflammatory effects using the AA rat model. Most of these compounds, especially those having an imidazole or a triazole moiety on the 2-alkyl chain, exhibited a potent effect. Among the compounds synthesized, ethyl 4-(3,4-dimethoxyphenyl)-6,7-dimethoxy-2-(1,2,4-triazol-1-yl-methyl)quinoline-3-carboxylate (12d), having an ED(50) value of 2.6 mg/kg/day (anti-inflammatory effect in an AA rat model, po), was selected as a candidate for further investigation. In vitro, 12d inhibited mitogen-induced proliferation at 10(-7)-10(-5) M but not prostaglandin E(2) production at 10(-5) M. Moreover, 12d preferentially inhibited the IFN-gamma production by Th1-type clones over the IL-4 production by Th2-type clones. This preferential suppression of Th1 cytokine production is considered the essential immunomodulating action of 12d for the present. Synthesis and structure-activity relationships for this novel series of quinoline and quinazoline derivatives are detailed.
