Polyvinyl alcohol-based electrospun matrix as a delivery system for nanoemulsion containing chalcone against Leishmania (Leishmania) amazonensis. Colloids Surf B Biointerfaces 2020; 198:111390. [PMID: 33208279 DOI: 10.1016/j.colsurfb.2020.111390] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Revised: 08/08/2020] [Accepted: 09/28/2020] [Indexed: 10/23/2022]
Abstract
Cutaneous leishmaniasis is a worldwide public health problem. Conventional therapies, in addition to the high cost, have many adverse effects and cases of parasite's resistance. Chalcones are secondary metabolites precursors in the flavonoid pathway and can be obtained naturally, but with low yield from plant raw material. Thus, the use of synthetic chalcones has been a promising strategy for the development of molecules with leishmanicidal activity. Thus, this work aimed to develop a controlled release system of two synthetic chalcone (trans-chalcones and 3'-(trifluormethyl)-chalcone) using polyvinyl alcohol nanofibers (PVA) as scaffold. The association of chalcones to the nanofibers was made by nanoemulsions (NE) thereof, i.e., a colloidal system on a nanometric scale, which allows compounds with opposite polarities to remain miscible and stable throughout their manipulation. Chalcone nanoemulsions were developed using the spontaneous emulsification technique. The NE were characterized regarding their particle size, polydispersion index (PDI), and zeta potential. The results showed NE with spherical shape, absolute values of zeta potential were higher than 30 mV and homogeneous distribution pattern (PDI < 0.3). Dynamics light scattering (DLS) analysis showed similar hydrodynamic rays, i.e., 180 nm (trans-chalcone NE) and 178 nm (NE containing 3'-(trifluormethyl)-chalcone, in addition to presenting encapsulation efficiency values close to 100 %. Subsequently, the NE were added to a polymeric solution of polyvinyl alcohol (PVA) and processed via the electrospinning technique affording a PVA matrix (15 %, w/v) nanofiber containing the chalcones NE at 1 mg.mL-1. In a follow-up experiment, the skin permeation assay of the PVA matrix-chalcone NE was performed in vitro using Franz type diffusion cells and porcine ear as biological model of study. The results showed that the treatments with the nanofibers containing the chalcone NE were retained mainly in the stratum corneum, while the NE suspensions containing chalcone were retained in the epidermis and dermis. This result is thought to be relevant, since parasites are located mainly in the dermis. Further, in vitro assay against the amastigote form of L. (L) amazonensis, showed IC50 values to trans-chalcone and 3'-(trifluormethyl)-chalcone of 24.42 ± 6.76 μg.mL-1 and 15.36 ± 4.61 μg.mL-1, respectively. In addition to improving the solubility of the compounds tested in culture medium without using organic solvents, chalcones in nano-emulsified form reduced the IC50 to 9.09 ± 1.24 μg.mL-1 (trans-chalcone) and 10.27 ± 2.27 μg.mL-1 (3'-(trifluormethyl)-chalcone) which confirmed the potential of the nanoemulsion containing chalcone for cutaneous leishmaniasis treatment.

Abstract
Targeting of therapeutic agents to their specific site of action not only increases the treatment efficacy, but also reduces systemic toxicity. Therefore, various drug delivery systems (DDSs) have been developed to achieve this target. However, most of those DDSs have several issues regarding biocompatibility and environmental hazard. In contrast to the synthetic DDSs, exosome-based natural carriers are biocompatible, biodegradable and safe for the environment. Since exosomes play a role in intercellular communication, they have been widely utilized as carriers for different therapeutic agents. This article was aimed to provide an overview of exosomes as an environment-friendly DDS in terms of engineering, isolation, characterization, application and limitation.

Abstract
Inonotus hispidus is an anti-tumour drug used in folk medicine. (4S,5S)-4-Hydroxy-3,5-dimethoxycyclohex-2-enone (HDE) is a compound isolated from Inonotus hispidus for the first time. However, the mechanisms underlying its therapeutic effects have not been elucidated. In this study, the in vitro screening, in vivo anti-tumour effects, mechanism of action, pharmacokinetics, and tissue distribution of HDE were investigated. HDE could inhibit the proliferation of HepG2 cells. Additionally, its half-maximal inhibitory concentration was 7.9 µg/mL. Increasing HDE concentrations significantly increased apoptosis rate in a dose-dependent manner. Furthermore, HDE was rapidly absorbed into mouse plasma, reaching a maximum concentration at 30 min. The area under the plasma HDE concentration-time curves for the studied organs were as follows: spleen > liver > lung > kidney > muscle > thymus > heart > brain. HDE also inhibited tumour growth up to 69%. The weights of organs harvested from HDE-treated mice were not significantly different from those harvested from control mice. Furthermore, HDE upregulated Fas expression and downregulated FasL expression in HepG2 cells. HDE significantly increased caspase-3 and caspase-8 activity. The anti-tumour effect of HDE might be realized by activating the Fas-mediated apoptotic pathway. We also found that HDE undergoes enterohepatic circulation or is quickly absorbed by the body, and the drug is released back into systemic circulation. In conclusion, HDE significantly inhibited H22 hepatocarcinoma cells (H22)tumour growth in mice without damaging organs; therefore, it may be suitable for treating liver cancer.

Abstract
Personalized and precise nanomedicines are highly demanded for today’s medical needs. Liposomes are ideal candidates for the construction of multifunctional drug delivery systems. In this study, a liposome was used to improve the clinical issues of docetaxel (Doc), a potent antimitotic chemotherapy for prostate cancer (PC). RLT, a low-density lipoprotein receptor (LDLR)-binding peptide, and PEG were conjugated to the liposomes, and gold nanorods (GNRs) were also incorporated into the liposomes. The GNRs/Doc-liposome-RLT (GNRs/DocL-R) was tested in PC-3 cells and in PC-3 tumor-bearing nude mice. Results showed that GNRs/DocL-R possessed a diameter approximately 163.15±1.83 nm and a zeta potential approximately −32.8±2.16 mV. GNRs/DocL-R showed enhanced intracellular entrance, increased accumulation in the implanted tumor region, and the highest tumor inhibition in vitro and in vivo. Therefore, the multifunctional GNRs/DocL-R was a potential cancer treatment via combined chemo- and thermotherapy.

Abstract
For targeted gastric carcinoma therapy, hyaluronic acid (HA)-modified layer-by-layer nanoparticles (NPs) are applied for improving anticancer treatment efficacy and reducing toxicity and side effects. The aim of this study was to develop HA-modified NPs for the co-loading of irinotecan (IRN) and 5-fluorouracil (5-FU). A novel polymer–chitosan (CH)–HA hybrid formulation (HA–CH–IRN/5-FU NPs) consisting of poly(d,l-lactide-co-glycolide) (PLGA) and IRN as the core, CH and 5-FU as a shell on the core and HA as the outmost layer was prepared. Its morphology, average size, zeta potential and drug encapsulation ability were evaluated. Human gastric carcinoma cells (MGC803 cells) and cancer-bearing mice were used for the testing of in vitro cytotoxicity and in vivo antitumor efficiency of NPs. HA–CH–IRN/5-FU NPs displayed enhanced antitumor activity in vitro and in vivo than non-modified NPs, single drug-loaded NPs and drugs solutions. The results demonstrate that HA–CH–IRN/5-FU NPs can achieve impressive antitumor activity and the novel targeted drug delivery system offers a promising strategy for the treatment of gastric cancer.
