Preparation and application of sustainable polymers derived from renewable resources are of great significance. The aim of this study is to synthesize a kind of sustainable polymeric micelles from rosin and vegetable oils via atom transfer radical polymerization (ATRP) and to investigate the doxorubicin delivery properties of these micelles. Dehydroabietic acid–based poly lauryl methacrylate (DA-PLMA) with narrow PDI of 1.13 was prepared in a well-controlled process using rosin as an ATRP initiator. Thereafter, carboxylic groups were introduced to form poly methacrylic acid (PMAA) moieties in DA-PLMA polymer via acid hydrolysis. The resulted DA-PLMA-PMAA could self-assemble in water to form pH-dependent polymeric micelles with a diameter of ∼65 nm and PDI as low as 0.105. Owing to the existence of rosin, DA-PLMA-PMAA micelles also showed self-fluorescence properties. In addition, Dox-loaded micelles were prepared in aqueous solution with the drug-loading capacity as high as 16.0% and showed sustained-release characteristics. These results demonstrate great promise for designing polymeric micellar from rosin and vegetable oils.

<p>Lipid-based nanoparticles (LBNs) are a new type of nanoparticulate drug delivery system, which have been gradually shown broad prospects in pulmonary drug delivery systems. However, the main disadvantage of these LBNs for inhalable drugs with limited lipophilicity is the low encapsulation capacity. Herein, this study anticipates establishing a technology platform to improve the loading capacity of low lipophilicity drugs in LBNs, for the therapy of lung diseases. A proof-of-concept was carried out using Beclomethasone dipropionate (BDP) as a model drug. BDP was conjugated with stearic acid (SA), a kind of the lipid matrix for LBN. The conjugate was characterized and the interactions between the conjugate and SA were investigated by molecular dynamics simulation. It is expected that the drug loading capacity of weak-lipophilic drugs in LBN can be increased by establishing the technology platform, and the application of LBNs in pulmonary delivery can be broadened.</p>

Dual Targeting

A dual-targeting drug delivery system (DTDDS) with magnetic targeting and active targeting was obtained to improve the targeting and drug-loading capacity of magnetic drug nanocarriers. An ultraviolet-visible spectrophotometer and flow cytometry were used to investigate the drug-loading and release capacity, cytotoxicity, and inhibition of tumor cell proliferation, separately. Results show that DTDDS has obvious magnetic characteristics, on which the modification amount of folic acid is 64.82 mg g-1. Doxorubicin was taken as a template drug to evaluate its drug-loading capacity, which was as high as 577.12 mg g-1. Good biocompatibility and low cytotoxicity of DTDDS were further confirmed. Moreover, DTDDS can target the folate receptor on the surface of HeLa cells and deliver doxorubicin into HeLa cells, thereby increasing the proliferation inhibition for cancer cells. Therefore, this new dual-targeting drug delivery system shows potential in significantly reducing the toxic side effects of chemotherapy and improving chemotherapy efficiency.
