PURPOSE: Artemisinin (ART) has anti-inflammatory, antimicrobial, antioxidant, anti-amyloid, and anti-malarial effects, but its application is limited due to its low water solubility and poor oral bioavailability. In this study, the bioavailability, water solubility, and anti-plasmodial property of ART were improved by PCL-PEG-PCL tri-block copolymers. METHODS: The structure of the copolymers was characterized by (1)H NMR, FT-IR, DSC, and GPC techniques. ART was encapsulated within micelles by a single-step nano-precipitation method, leading to the formation of ART-loaded PCL-PEG-PCL micelles. The obtained micelles were characterized by dynamic light scattering (DLS) and atomic force microscopy (AFM). The in vivo anti-plasmodial activity of ART-loaded micelles was measured against Plasmodium berghei infected Swiss albino mice. RESULTS: The results showed that the zeta potential of ART-loaded micelles was about -8.37 mV and the average size was 91.87 nm. ART was encapsulated into PCL-PEG-PCL micelles with a loading capacity of 19.33 +/- 0.015% and encapsulation efficacy of 87.21 +/- 3.32%. In vivo anti-plasmodial results against P. berghei showed that multiple injections of ART-loaded micelles could prolong the circulation time and increase the therapeutic efficacy of ART. CONCLUSION: These results suggested that PCL-PEG-PCL micelles would be a potential carrier for ART for the treatment of malaria.
