AB  - Objectives: Malaria treatment is impeded by increasing resistance to conventional antimalarial drugs. Here we explored the activity of ten novel benzothiophene, thiophene and benzene aminoquinolines. Methods: In vitro testing was performed by the lactate dehydrogenase assay in chloroquine (CQ)-sensitive Plasmodium falciparum strain 3D7 and CQ-resistant (CQ(R)) P. falciparum strain Dd2. In vivo activity was evaluated by a modified Thompson test using C57BL/6 mice infected with Plasmodium berghei ANKA strain. Results: Nine of the ten compounds had a lower 50% inhibitory concentration (IC50) than CQ against the CQ(R) strain Dd2. Five of these compounds that were available for in vivo evaluation were shown to be nontoxic. All five compounds administered at a dose of 160 mg/kg/day for 3 days prolonged the survival of treated compared with untreated mice. Untreated control mice died by Day 7 with a mean parasitaemia of 15%. Among treated mice, a dichotomous outcome was observed, with a two-third majority of treated mice dying by Day 17 with a low mean parasitaemia of 5%, whilst one-third survived longer with a mean hyperparasitaemia of 70%; specifically, five of these mice survived a mean of 25 days, whilst two even survived past Day 31. Conclusions: The significant antimalarial potential of this aminoquinoline series is illustrated by its excellent in vitro activity against the CQ(R) P. falciparum strain and significant in vivo activity. Interestingly, compounds CIAQ7, CIAQ9 and CIAQ11 were able to confer resistance to cerebral malaria and afford a switch to hyperparasitaemia to mice prone to the neurological syndrome.

AB  - We herein report the design and synthesis of a novel series of thiophene-and furan-based aminoquinoline derivatives which were found to be potent antimalarials and inhibitors of b-hematin polymerization. Tested compounds were 3-71 times more potent in vitro than CQ against chloroquine-resistant (CQR) W2 strain with benzonitrile 30 being as active as mefloquine (MFQ), and almost all synthesized aminoquinolines (22/27) were more potent than MFQ against multidrug-resistant (MDR) strain C235. In vivo experiments revealed that compound 28 showed clearance with recrudescence at 40 mg/kg/day, while 5/5 mice survived in Thompson test at 160 mg/kg/day.
