Design and development of a soluble PDA-Emodin-PVP-MN patch and its anti-obesity effect in rats.
Emodin has been proven to have weight-reducing and lipid-lowering effects. In order to make emodin play a better anti-obesity role, we designed and developed an emodin loaded dissolving microneedle patch, in which emodin existed in the form of emodin-polyvinylpyrrolidone co-precipitate (Emodin-PVP). Meanwhile, polydopamine (PDA) was added to the microneedle patch (PDA-Emodin-PVP-MN) for photothermal-enhanced chemotherapy of obesity. The average weight of the patch was 0.1 ± 0.05 g and the drug loading was 0.37 ± 0.031 mg. After 5 min of NIR irradiation (808 nm, 0.6 W/cm2), the rat abdominal temperature could reach 48 ℃, and the cumulative release of emodin reached 96.25%. The diffusion coefficient of emodin in the in vitro agar diffusion experiment was 249.27 mm2 h-1. No obvious toxicity was observed in hemolysis test, CCK-8 assay and microscopic histopathological analysis. The patch significantly reduced the percent of body weight ( P < 0.01), lipid-body ratio ( P < 0.001), serum FFAs ( P < 0.01) and the cell volume of peritesticular adipose tissue in the high-fat diet induced obese rats, indicating the patch had good anti-obesity effect. The mechanism of action may be related to the up-regulation of HSL and LPL protein levels in rat peritesticular adipose tissue.
期刊介绍：
The journal provides a unique forum for scientific publication of high-quality research that is exclusively focused on translational aspects of drug delivery. Rationally developed, effective delivery systems can potentially affect clinical outcome in different disease conditions.
Research focused on the following areas of translational drug delivery research will be considered for publication in the journal.
Designing and developing novel drug delivery systems, with a focus on their application to disease conditions;
Preclinical and clinical data related to drug delivery systems;
Drug distribution, pharmacokinetics, clearance, with drug delivery systems as compared to traditional dosing to demonstrate beneficial outcomes
Short-term and long-term biocompatibility of drug delivery systems, host response;
Biomaterials with growth factors for stem-cell differentiation in regenerative medicine and tissue engineering;
Image-guided drug therapy,
Nanomedicine;
Devices for drug delivery and drug/device combination products.
In addition to original full-length papers, communications, and reviews, the journal includes editorials, reports of future meetings, research highlights, and announcements pertaining to the activities of the Controlled Release Society.
