采用BF3·OEt2催化的分子内Povarov反应,合成了15个含色吡啶的噻唑基-2-吡啶酮类多肽类化合物。该反应与几个O-烷基化的水杨醛和氨基官能化的噻唑基-2-吡啶酮反应,生成具有不同取代度的多杂环。对合成的化合物体外结合α-突触核蛋白和淀粉样蛋白β纤维的能力进行了筛选。被硝基取代的类似物与成熟的淀粉样纤维结合,而且活性还取决于这个官能团的位置。
A BF3·OEt2 catalyzed intramolecular Povarov reaction was used to synthesize 15 chromenopyridine fused thiazolino-2-pyridone peptidomimetics. The reaction works with several O-alkylated salicylaldehydes and amino functionalized thiazolino-2-pyridones, to generate polyheterocycles with diverse substitution. The synthesized compounds were screened for their ability to bind α-synuclein and amyloid β fibrils in vitro. Analogues substituted with a nitro group bind to mature amyloid fibrils, and the activity moreover depends on the positioning of this functional group.
