  Synthesis of halogenated 4-quinolones and evaluation of their antiplasmodial activity

  摘要：

  Treatment of 4-hydroxyquinolines with (2-methyl) allyl bromide in the presence of K2CO3 resulted in the formation of novel N-[(2-methyl) allyl]-4-quinolones through selective N-alkylation. Further reaction of N-(2-methylallyl)-4-quinolones with bromine or N-bromosuccinimide yielded the corresponding 3-bromo- 1-(2,3-dibromo-2-methylpropyl)-4-quinolones and 3-bromo-1-(2-methylallyl)-4-quinolones, respectively. Furthermore, a copper-catalyzed C-N coupling of the latter 3-bromo-4-quinolones with (5-chloro) indole afforded novel 3-[(5-chloro) indol-1-yl]-4-quinolone hybrids. Antifungal and antiplasmodial assays of all new 4-quinolones were performed and revealed no antifungal properties but moderate antiplasmodial activities. All 15 compounds displayed micromolar activities against a chloroquine- sensitive strain of Plasmodium falciparum, and the five most potent compounds also showed micromolar activities against a chloroquine-resistant strain of P. falciparum with IC50-values ranging between 4 and 70 mu M.

  This study presents a method for synthesizing pyridine, quinoline, and isoquinoline ketones from 2-halogenated N-heterocycles under mild conditions. The use of H2O as both solvent and oxygen source makes the reaction environmentally friendly, with broad substrate applicability and high functional group tolerance.
