Special Issue Information

Dear Colleagues,

The rational design of innovative nanodevices has opened up endless opportunities to develop the next generation of personalized therapies for patients. Due to their unique physical and chemical properties, nanoparticle-based platforms have emerged as potential tools to improve the pharmacokinetic profiles of conventional therapeutic and diagnostic agents. 

This Special Issue will be focused on the chemical strategies that have recently been developed for the design of engineered nanosystems to achieve the selective and efficient transport of bioactive compounds, ranging from small molecules to biomolecules such as nucleic acids and proteins. Recent developments in the use of nanomaterials as vehicles to administer various therapeutic and/or diagnostic substances, emphasizing the advantages of each specific chemical strategy (e.g., optimal loading, improved half-life and bioavailability) will be reported. In addition, this Issue includes the safety considerations and regulatory issues to carry out the rational design of nanoparticles, as well as preclinical characterization together with challenges and perspectives to be considered in order for nanotherapies to become a reality with diagnostic and therapeutic application. 

In this Special Issue, authors are invited to submit original research articles, reviews, and short communications exploring recent advances in the rational design of chemical strategies to develop diagnostic and/or therapeutic nanodevices and related topics to ensure the clinical translation of nanomedicine.

This work aimed to enhance the purposing profile of Etodolac (ETD) in Human Hepatocellular Carcinoma (HCC) HepG2 cells using sodium deoxycholate stabilized zein nanospheres (ETD-SDZN NSs). ETD-SDZN NSs were formulated using the nan-precipitation method and were characterized, in particular, in terms of mean particle size, zeta potential, encapsulation efficiency, colloidal stability and bioaccessibility. Estimations of cytotoxicity, cellular uptake, cell cycle progression, Annexin-V staining, mRNA expression of apoptotic genes and oxidative stress evaluations were conducted. The ETD-SDZN NSs selected formula obtained an average particle size of 113.6 ± 7.4 nm, a zeta potential value of 32.7 ± 2.3 mV, an encapsulation efficiency of 93.3 ± 5.2%, enhanced bioaccessibility and significantly reduced IC50 against HepG2 cells, by approximately 13 times. There was also enhanced cellular uptake, accumulation in G2-M phase and elevated percentage cells in pre-G1 phase, significant elevated mRNA expression of P53, significant reduced expression of Cyclin-dependent kinase 1 (CDK1) and Cyclooxygenase-2 (COX-2) with enhanced oxidative stress by reducing glutathione reductase (GR) level, ameliorated reactive oxygen species (ROS) generation and lipid peroxidation outputs. ETD-SDZN NSs obtained a supreme cell death-inducing profile toward HepG2 cells compared to free ETD. The method of formulation was successful in acquiring the promising profile of ETD in HCC as a therapeutic molecule due to ameliorated cellular uptake, proapoptotic and oxidant potentials.
