Nanoparticle-based cancer therapeutics promises to improve drug delivery safety and efficacy. However, fabrication of consistent theranostic nanoparticles with high and controllable drug loading remains a challenge, primarily due to the cumbersome, multi-step synthesis processes conventionally applied. Here, we present a simple and highly controllable method for assembly of theranostic nanoparticles, which may greatly reduce batch-to-batch variation. The major components of this nanoparticle system include a superparamagnetic iron oxide nanoparticle (SPION), a biodegradable and pH-sensitive poly (beta-amino ester) (PBAE) copolymer, a chemotherapeutic agent doxorubicin (DOX). Here the polymer pre-loaded with drug is directly assembled to the surface of SPIONs forming a drug loaded nanoparticle (NP-DOX). NP-DOX demonstrated a high drug loading efficiency of 679 μg DOX per mg iron, sustained stability in cell culture media up to 7 days, and a strong r2 relaxivity of 146 mM-1·s-1 for magnetic resonance imaging (MRI). The drug release anal. of NP-DOX showed fast DOX release at pH 5.5 and 6.4 (as in endosomal environment) and slow release at pH 7.4 (physiol. condition), demonstrating pH-sensitive drug release kinetics. In vitro evaluation of NP-DOX efficacy using drug-resistant C6 glioma cells showed a 300% increase in cellular internalization at 24 h post-treatment and 65% reduction of IC50 at 72 h post-treatment when compared to free DOX. These nanoparticles could serve as a foundation for building smart theranostic formulations for sensitive detection through MRI and effective treatment of cancer by controlled drug release. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Formula: C10H14O5).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Formula: C10H14O5
