  Synthesis and biological evaluation of new imidazo[1,2-a]pyridine derivatives designed as mefloquine analogues

  摘要：

  This paper describes the synthesis and the in vitro antimalarial profile of two new imidazo[1,2-a]pyridine derivatives 4.HCl and 13.HCl, structurally proposed as mefloquine (1) analogues, by exploring bioisosterism and molecular simplification tools. The synthetic route employed to access the title compounds used, as starting material, the previously described ethyl 2-methylimidazo[1,2-a]pyridine-3-carboxylate derivative (5). These novel heterocyclic derivatives 4.HCl and 13.HCl presented modest antimalarial activity against the W-2 and D-6 clones of Plasmodium falciparum as well as inhibitors of in vitro heme polymerization compared to mefloquine.

  An efficient copper-catalyzed selective cross coupling of imidazo[1,2-a]pyridines with methyl hetarenes has been reported. This transformation opened a new route to synthesize the C-3 carbonyl imidazo[1,2-a]pyridine derivative, which is a common structural motif in natural products and pharmaceuticals. 18O-labeling experiments indicated that the oxygen source of products originated from O2.
