  Synthesis and Evaluation of 4-Aryl-2(1H)-quinolinones as Potent Amyloid β Fibrillogenesis Inhibitors

  摘要：

  4-Aryl-2(1H)-quinolinones were synthesized and evaluated in vitro as inhibitors of A beta(1-42) fibrillogenesis using a thioflavin T fluorescence method. The most potent anti-aggregating molecules (4b and 5c) were found among the derivatives bearing OH and/or OMe groups at C-4' (R-4) and/or C-6 (R-2) of the 4-aryl-2(1H)-quinolinone moiety. Furthermore, the derivative bearing 4'-F substituent (4f) proved to be a very active inhibitor.
