Special Issue Information

Dear Colleagues,

The global context of increasing drug-resistant diseases requires urgent actions to avert serious sanitary and economic crises. If no alternative treatments are proposed, it is expected that around 10 million deaths each year could be caused by drug-resistant microorganisms by 2050. Currently, lipid nanoparticles (LNPs) have emerged as promising carriers for delivering a wide variety of molecules with interesting antimicrobial, antifungal or anticancer properties. Different generations of LNPs, such as solid lipid nanoparticles, nanostructured lipid carriers, liposomes, or lipid–polymer hybrid nanoparticles, were developed to increase the physical stability and the bioavailability of cargo drugs. Those systems provide complex architectures with targeting molecules, increasing drug loading, co-loading of synergetic drugs, and tailorable surfaces that could be powerful weapons to treat bacterial infections.  

This Special Issue invites articles to present the recent advances in the development of lipid NPs with particular biological activities in the biomedical field. The Special Issue is intended to serve as a useful repository with new significant approaches to challenge the global advances of drug-resistance diseases caused by different microorganisms or even cancer cells.

Abstract
Plant and herbal essential oils (EOs) offer a wide range of pharmacological actions that include anticancer effects. Here, we evaluated the cytotoxic activity of EO from Lippia alba (chemotype linalool), L. alba (chemotype dihydrocarvone, LaDEO), Clinopodium nepeta (L.) Kuntze (CnEO), Eucalyptus globulus, [...] Read more.
Plant and herbal essential oils (EOs) offer a wide range of pharmacological actions that include anticancer effects. Here, we evaluated the cytotoxic activity of EO from Lippia alba (chemotype linalool), L. alba (chemotype dihydrocarvone, LaDEO), Clinopodium nepeta (L.) Kuntze (CnEO), Eucalyptus globulus, Origanum × paniculatum, Mentha × piperita, Mentha arvensis L., and Rosmarinus officinalis L. against human lung (A549) and colon (HCT-116) cancer cells. The cells were treated with increasing EO concentrations (0–500 µL/L) for 24 h, and cytotoxic activity was assessed. LaDEO and CnEO were the most potent EOs evaluated (IC50 range, 145–275 µL/L). The gas chromatography–mass spectrometry method was used to determine their composition. Considering EO limitations as therapeutic agents (poor water solubility, volatilization, and oxidation), we evaluated whether LaDEO and CnEO encapsulation into solid lipid nanoparticles (SLN/EO) enhanced their anticancer activity. Highly stable spherical SLN/LaDEO and SLN/CnEO SLN/EO were obtained, with a mean diameter of 140–150 nm, narrow size dispersion, and Z potential around −5mV. EO encapsulation strongly increased their anticancer activity, particularly in A549 cells exposed to SLN/CnEO (IC50 = 66 µL/L CnEO). The physicochemical characterization, biosafety, and anticancer mechanisms of SLN/CnEO were also evaluated in A549 cells. SLN/CnEO containing 97 ± 1% CnEO was highly stable for up to 6 months. An increased in vitro CnEO release from SLN at an acidic pH (endolysosomal compartment) was observed. SLN/CnEO proved to be safe against blood components and non-toxic for normal WI-38 cells at therapeutic concentrations. SLN/CnEO substantially enhanced A549 cell death and cell migration inhibition compared with free CnEO. Full article
