Abstract
The clinical application of EDV, a potent antioxidant drug approved for amyotrophic lateral sclerosis (ALS), is limited by its short biological half-life and poor water solubility necessitating hospitalization during intravenous infusion. Nanotechnology-based drug delivery constitutes a powerful tool through inferring drug stability and targeted drug delivery improving drug bioavailability at the diseased site. Nose-to-brain drug delivery offers direct access to the brain bypassing the blood brain barrier and reducing systemic biodistribution. In this study, we designed EDV-loaded poly(lactic-co-glycolic acid) (PLGA)-based polymeric nanoparticles (NP-EDV) for intranasal administration. NPs were formulated by the nanoprecipitation method. Morphology, EDV loading, physicochemical properties, shelf-life stability, in vitro release and pharmacokinetic assessment in mice were conducted. EDV was efficiently loaded into ∼90 nm NPs, stable up to 30 days of storage, at ∼3% drug loading. NP-EDV reduced H2O2-induced oxidative stress toxicity in mouse microglial cell line BV-2. Optical imaging and ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) showed that intranasal delivery of NP-EDV offered higher and more sustained brain uptake of EDV compared to intravenous administration. This study is the first of its kind to develop an ALS drug in a nanoparticulate formulation for nose-to-brain delivery raising hope to ALS patients where currently treatment options are limited to two clinically approved drugs only.

Lipid-core nanoparticles: Classification, preparation methods, routes of administration and recent advances in cancer treatment. Adv Colloid Interface Sci 2023; 314:102871. [PMID: 36958181 DOI: 10.1016/j.cis.2023.102871] [Citation(s) in RCA: 25] [Impact Index Per Article: 25.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 02/03/2023] [Accepted: 03/06/2023] [Indexed: 03/11/2023]
Abstract
Nanotechnological drug delivery platforms represent a new paradigm for cancer therapeutics as they improve the pharmacokinetic profile and distribution of chemotherapeutic agents over conventional formulations. Among nanoparticles, lipid-based nanoplatforms possessing a lipid core, that is, lipid-core nanoparticles (LCNPs), have gained increasing interest due to lipid properties such as high solubilizing potential, versatility, biocompatibility, and biodegradability. However, due to the wide spectrum of morphologies and types of LCNPs, there is a lack of consensus regarding their terminology and classification. According to the current state-of-the-art in this critical review, LCNPs are defined and classified based on the state of their lipidic components in liquid lipid nanoparticles (LLNs). These include lipid nanoemulsions (LNEs) and lipid nanocapsules (LNCs), solid lipid nanoparticles (SLNs) and nanostructured lipid nanocarriers (NLCs). In addition, we present a comprehensive and comparative description of the methods employed for their preparation, routes of administration and the fundamental role of physicochemical properties of LCNPs for efficient antitumoral drug-delivery application. Market available LCNPs, clinical trials and preclinical in vivo studies of promising LCNPs as potential treatments for different cancer pathologies are summarized.

Abstract
Cerebral malaria occurs due to Plasmodium falciparum infection, which causes 228 million infections and 450,000 deaths worldwide every year. African people are mostly affected with nearly 91% cases, of which 86% are pregnant women and infants. India and Brazil are the other two countries severely suffering from malaria endemicity. Commonly used drugs have severe side effects, and unfortunately no suitable vaccine is available in the market today. In this line, this review is focused on polymeric nanomaterials and nanocapsules that can be used for the development of effective diagnostic strategies, nanomedicines, and vaccines in the management of cerebral malaria. Further, this review will help scientists and medical professionals by updating the status on the development stages of polymeric nanoparticle based diagnostics, nanomedicines, and vaccines and strategies to eradicate cerebral malaria. In addition to this, the predominant focus of this review is antimalarial agents based on polymer nanomedicines that are currently in the preclinical and clinical trial stages, and potential developments are suggested as well. This review further will have an important social and commercial impact worldwide for the development of polymeric nanomedicines and strategies for the treatment of cerebral malaria.

Abstract
The goal of this work was the development of natural polymeric microcapsules for antimicrobial drug delivery - triclosan loaded alginate and chitosan-based microcapsules for potential coating applications in substrates such as textiles or plastics. Microcapsules containing 2.5% (w/w) or 3% (w/w) triclosan in both core and matrix were synthesized and evaluated by Fourier-transform infrared spectroscopy, scanning electron microscopy, confocal microscopy, differential scanning calorimetry, thermogravimetry, and antimicrobial activity. The microcapsules produced featured spherical and mostly irregularly-shaped surfaces composed by an alginate core in a chitosan outer matrix, as revealed by confocal microscopy, and antimicrobial activity against S. aureus and E. coli with inhibition halos up to 60 mm and 25 mm respectively, granted by a triclosan loading of 61.66%. The thermal analysis suggested that the polymers protected the active substance from temperature-induced degradation. In conclusion, these microcapsules may be applied toward antimicrobial functionalization of plastics, textiles and other materials.

Development and in vivo evaluation of an innovative "Hydrochlorothiazide-in Cyclodextrins-in Solid Lipid Nanoparticles" formulation with sustained release and enhanced oral bioavailability for potential hypertension treatment in pediatrics. Int J Pharm 2017; 521:73-83. [PMID: 28229944 DOI: 10.1016/j.ijpharm.2017.02.022] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2017] [Revised: 02/07/2017] [Accepted: 02/08/2017] [Indexed: 01/16/2023]
Abstract
An innovative pediatric oral formulation of hydrochlorothiazide (HCT) (2mg/mL), endowed with improved bioavailability and sustained release properties and suitable for the hypertension treatment in pediatric patients, was developed by combining the drug-cyclodextrin complexation and the incorporation of the complex into Solid Lipid Nanoparticles (SLN). Precirol®ATO5-based SLN, with two different surfactants (Pluronic®F68 and Tween®80) loaded with the drug as such or as binary system with hydroxypropyl-beta-cyclodextrin (HPβCd) and sulfobutyl-ether-beta-cyclodextrin (SBEβCd) both as physical mixture (P.M.) or coground product (GR), were prepared using the hot high-shear homogenization followed by ultrasonication method. Loading of the drug:HPβCd both as P.M. and GR gave rise to nanoparticle formation, differently from the HCT:SBEβCd ones, with an entrapment efficiency of about 65%. Such SLN formulations showed an improvement of the drug release rate compared both to the drug suspension and to the free drug-loaded SLN. In all cases the SLN containing the GR systems exhibited better performances than the corresponding with P.M. However, the presence of Tween®80 gave rise to the complete drug release after only 150min, without providing a sustained release, whereas Pluronic®F68-based SLN containing GR were able to assure a sustained release over the time achieving more than 75% drug released at the end of the test, maintaining a constant 1.8-fold increase respect to simple drug suspension. Pluronic®F68-based SLN showed a pharmaceutically acceptable stability up to three months. In vivo studies highlighted the effectiveness of such formulations, enabling a concomitant increased diuretic effect and a sustained drug release and, consequently, enhanced HCT oral bioavailability.

Abstract
Clinical applications of curcumin for the treatment of cancer and other chronic diseases have been mainly hindered by its short biological half-life and poor water solubility. Nanotechnology-based drug delivery systems have the potential to enhance the efficacy of poorly soluble drugs for systemic delivery. This study proposes the use of poly(lactic-co-glycolic acid) (PLGA)-based polymeric oil-cored nanocapsules (NCs) for curcumin loading and delivery to colon cancer in mice after systemic injection. Formulations of different oil compositions are prepared and characterized for their curcumin loading, physico-chemical properties, and shelf-life stability. The results indicate that castor oil-cored PLGA-based NC achieves high drug loading efficiency (≈18% w(drug)/w(polymer)%) compared to previously reported NCs. Curcumin-loaded NCs internalize more efficiently in CT26 cells than the free drug, and exert therapeutic activity in vitro, leading to apoptosis and blocking the cell cycle. In addition, the formulated NC exhibits an extended blood circulation profile compared to the non-PEGylated NC, and accumulates in the subcutaneous CT26-tumors in mice, after systemic administration. The results are confirmed by optical and single photon emission computed tomography/computed tomography (SPECT/CT) imaging. In vivo growth delay studies are performed, and significantly smaller tumor volumes are achieved compared to empty NC injected animals. This study shows the great potential of the formulated NC for treating colon cancer.

Abstract
The preventative effect of triclosan (TS) and TS liposomal nanoparticles was studied on the early establishment of chronic infection with Toxoplasma gondii (T. gondii). Swiss albino mice were orally infected with 10 cysts of avirulent ME49 strain of T. gondii, and 2 weeks later they were orally treated with dual daily doses of 200mg/kg and 120 mg/kg TS and TS liposomes for 30 days; respectively. Effect of TS and TS liposomes was parasitologically and ultrastructurally evaluated, versus infected non-treated control. Their safety was biochemically assessed. Parasitologically, both TS and TS liposomes induced significant reduction in mice mortality, brain parasite burden and infectivity of cysts obtained from the brains of treated mice. Ultrastructurally, scanning electron microscopy of cysts obtained from infected mice treated with either TS or TS liposomes showed surface irregularities, protrusions and depressions. Transmission electron microscopy revealed disintegration of the cyst wall and vacuolation of the bradyzoites with disintegration of plasma membranes of both cysts and bradyzoites whether treated with TS or TS liposomes. Biochemical study reflected the safety of the TS and TS liposomes. Therefore, TS proved an effective, promising and safe preventive drug against early establishment of chronic toxoplasmosis. Loading TS on liposomes marginally enhanced its efficacy against T. gondii cysts yet allowed its use in a lower dose.

Abstract
Efficacy of triclosan (TS) and TS-loaded liposomes against the virulent strain of Toxoplasma gondii (T. gondii) was evaluated. Swiss albino mice were intraperitoneally infected with 10(4) tachyzoites of RH HXGPRT(-) strain of T. gondii, then were orally treated with 150 mg/kg TS or 100 mg/kg TS liposomes twice daily for 4 days. Mice mortality, peritoneal and liver parasite burdens, viability, infectivity and ultrastructural changes of peritoneal tachyzoites of infected treated mice were studied, in comparison with those of infected non-treated controls. Drug safety was biochemically assessed by measuring liver enzymes and thyroxin. Both TS and TS liposomes induced significant reduction in mice mortality, parasite burden, viability and infectivity of tachyzoites harvested from infected treated mice. Scanning electron microscopy of treated tachyzoites showed distorted shapes, reduced sizes, irregularities, surface protrusions, erosions and peeling besides apical region distortion. Transmission electron microscopy showed that treated tachyzoites were intracellularly distorted, had cytoplasmic vacuolation, discontinuous plasma membranes, nuclear abnormalities and disrupted internal structures. Besides, in TS liposomes-treated subgroup, most tachyzoites were seen intracellularly with complete disintegration of the parasite plasma and nuclear membranes, with complete destruction of the internal structures. Biochemical safety of TS and TS liposomes was proven. Accordingly, TS can be considered as a promising alternative to the standard therapy for treating acute murine toxoplasmosis. Liposomal formulation of TS enhanced its efficacy and allowed its use in a lower dose.

Abstract
UNLABELLED Several synthetic metallated protoporphyrins (M-PPIX) were tested for their ability to block the cell cycle of the lethal human malaria parasite Plasmodium falciparum. After encapsulating the porphyrin derivatives in micro- and nanocapsules of marine atelocollagen, their effects on cultures of red blood cells infected (RBC) with P. falciparum were verified. RBCs infected with synchronized P. falciparum incubated for 48 h showed a toxic effect over a micromolar range. Strikingly, the IC50 of encapsulated metalloporphyrins reached nanomolar concentrations, where Zn-PPIX showed the best antimalarial effect, with an IC50=330 nM. This value is an 80-fold increase in the antimalarial activity compared to the antimalarial effect of non-encapsulated Zn-PPIX. These findings reveal that the incubation of P. falciparum infected-RBCs with 20 μM Zn-PPIX reduced the size of hemozoin crystal by 34%, whereas a 28% reduction was noticed with chloroquine, confirming the importance of heme detoxification pathway in drug therapy. FROM THE CLINICAL EDITOR In this study, synthetic metalloporphyrins were tested as therapeutics that target Plasmodium falciparum. The IC50 of encapsulated metalloporphyrins was found to be in the nanomolar concentration range, with encapsulated Zn-PPIX showing an 80-fold increase in its antimalarial activity compared to the non-encapsulated form.

Abstract
Despite the fact that we live in an era of advanced technology and innovation, infectious diseases, like malaria, continue to be one of the greatest health challenges worldwide. The main drawbacks of conventional malaria chemotherapy are the development of multiple drug resistance and the non-specific targeting to intracellular parasites, resulting in high dose requirements and subsequent intolerable toxicity. Nanosized carriers have been receiving special attention with the aim of minimizing the side effects of drug therapy, such as poor bioavailability and the selectivity of drugs. Several nanosized delivery systems have already proved their effectiveness in animal models for the treatment and prophylaxis of malaria. A number of strategies to deliver antimalarials using nanocarriers and the mechanisms that facilitate their targeting to Plasmodium spp.-infected cells are discussed in this review. Taking into account the peculiarities of malaria parasites, the focus is placed particularly on lipid-based (e.g., liposomes, solid lipid nanoparticles and nano and microemulsions) and polymer-based nanocarriers (nanocapsules and nanospheres). This review emphasizes the main requirements for developing new nanotechnology-based carriers as a promising choice in malaria treatment, especially in the case of severe cerebral malaria.

Abstract
Nanotechnology encompasses those technologies used to fabricate materials, including sphere, cubic and needle-like nanoscaled particles (approximately 5–100 nm), and near-nanoscaled devices (up to micrometres). In comparison, mycoplasma are approximately 200 nm in length, and a nanometre is 10−9 of a metre. The field of nanotechnology is experiencing rapid growth, with many and diverse potential applications being explored in the biomedical field, including the control of infectious diseases. Nanotechnology not only has the potential to offer improvements to current approaches for immunisation, drug design and delivery, diagnostics and cross-infection control, but is also unexpectedly delivering many new tools and capabilities.

Abstract
There is a dire need for novel therapeutics to treat the virulent malarial parasite, Plasmodium falciparum. Recently, the X-ray crystal structure of enoyl-acyl carrier protein reductase (ENR) in complex with triclosan has been determined and provides an opportunity for the rational design of novel inhibitors targeting the active site of ENR. Here, we report the discovery of several compounds by virtual screening and their experimental validation as high potency PfENR inhibitors.

Abstract
Most of the newly designed drug molecules are characterised by low solubility in aqueous medium, low permeability through biological membranes and/or an insufficient stability in the biological environment. Fundamental studies have provided proof-of-concept of the potential of particulate nanocarriers for overcoming these unsuitable properties. For example, it is known that polymeric nanosystems may enhance transmucosal transport of drugs with poor penetration capacities while preserving their biological activity. Moreover, in recent years it has become clear that through an appropriate selection of the nanosystem components it is possible to enhance its affinity for the mucosa and, hence, the residence time of the drug in contact with the absorptive epithelium. These properties, combined with a suitably tailored release profile can markedly increase the efficacy of pharmaceuticals. Overall, the properties that have been identified as critical for the performance of these delivery systems are particle size, surface charge and surface chemical composition. These properties are known to affect the physical and chemical stability of the nanoparticles in the biological environment as well as their ability to interact (unspecific bioadhesion, receptor-mediated interaction and so on) and, eventually, overcome biological barriers. The present article aims to critically review the latest advances in this area and to provide some insights into these complex issues. Thus, herein the most widely investigated transmucosal drug delivery nanosystems and their most promising applications are reported.
