Enantiomerically pure amino-alcohol quinolines: in vitro anti-malarial activity in combination with dihydroartemisinin, cytotoxicity and in vivo efficacy in a Plasmodium berghei mouse model.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAs resistance to marketed anti-malarial drugs continues to spread, the need for new molecules active on Plasmodium falciparum-resistant strains grows. Pure (S) enantiomers of amino-alcohol quinolines previously displayed a good in vitro anti-malarial activity. Therefore, a more thorough assessment of their potential clinical use through a rodent model and an in vitro evaluation of their combination with artemisinin was undertaken.
methodsScreening on a panel of P. falciparum clones with varying resistance profiles and regional origins was performed for the (S)-pentyl and (S)-heptyl substituted quinoline derivatives, followed by an in vitro assessment of their combination with dihydroartemisinin (DHA) on the 3D7 clone and an in vivo assay in a mouse model infected with Plasmodium berghei. Their haemolytic activity was also determined.
resultsA steady anti-malarial activity of the compounds tested was found, whatever the resistance profile or the regional origin of the strain. (S)-quinoline derivatives were at least three times more potent than mefloquine (MQ), their structurally close parent. The in vitro combination with DHA yielded an additive or synergic effect for both that was as good as that of the DHA/MQ combination. In vivo, survival rates were similar to those of MQ for the two compounds at a lower dose, despite a lack of clearance of the parasite blood stages. A 50% haemolysis was observed for concentrations at least 1,000-fold higher than the antiplasmodial IC50s.
conclusionsThe results obtained make those two (S)-amino-alcohol quinoline derivatives good candidates for the development of new artemisinin-based combination therapy (ACT), hopefully with fewer neurologic side effects than those currently marketed ACT, including MQ.
