IC50: 0.1-5.2 nM for various P. falciparum strains [1]
Malaria remains a disease of devastating global impact, killing more than 800,000 people every year-the vast majority being children under the age of 5. Naphthoquine phosphate is a antimalarial drug developed in China.
In vitro: Naphthoquine phosphate showed promising antimalaria acitivities against various P. falciparum strains. Moreover, previoius study highlighted that naphthoquine did not lose potency when tested against chloroquine resistant strains [1].
In vivo: In an study aiming to investigate the antimalarial activity of naphthoquine phosphate combined with artemisinine against Plasmodium knowlesi in rhesus monkey, it was found that the combination of naphthoquine phosphate and artemisinine was superior to the single component and the optimum proportion in the combination is 1 : 2.5 in treating P. knowlesi infection in monkeys [2].
Clinical trial: An oral single dose of the combination drug (400 mg of naphthoquine + 1000mg artemisinin) was administered to adult uncomplicated falciparum malaria patients. Mean fever clearance time, parasite clearance time were 18.2 ± 8.6 h and 34.6 ± 14.3 h, respectively. Adequate clinical and parasitological response was achieved in 52 out of 54 cases, the rate being 98.1%. The drug was well tolerated and no adverse reactionswere detected in the patients [3].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
