To develop new classes of antimalarial agents, the possibility of replacing the phenolic ring of amodiaquine, tebuquine, and isoquine with other aromatic nuclei was investigated. Within a first set of pyrrole analogues, several compounds displayed high activity against both D10 (CQ-S) and W-2 (CQ-R) strains of Plasmodium falciparum. The isoquine structure was also modified by replacing the diethylamino group with more metabolically stable bicyclic moieties and by replacing the aromatic hydroxyl function with a chlorine atom. Among these compounds, two quinolizidinylmethylamino derivatives (6f and 7f) displayed high activity against both CQ-S and CQ-R strains.

Abstract
To develop new classes of antimalarial agents, the possibility of replacing the phenolic ring of amodiaquine, tebuquine, and isoquine with other aromatic nuclei was investigated. Within a first set of pyrrole analogues, several compounds displayed high activity against both D10 (CQ-S) and W-2 (CQ-R) strains of Plasmodium falciparum. The isoquine structure was also modified by replacing the diethylamino group with more metabolically stable bicyclic moieties and by replacing the aromatic hydroxyl function with a chlorine atom. Among these compounds, two quinolizidinylmethylamino derivatives (6f and 7f) displayed high activity against both CQ-S and CQ-R strains.Pubblicazioni consigliate
