Targeted Delivery Systems

Targeted delivery systems of nanobiomaterials are necessary to be developed for the diagnosis and treatment of cancer. Nanobiomaterials can be engineered to recognize cancer-specific receptors at the cellular levels and to deliver anticancer drugs into the diseased sites. In particular, nanobiomaterial-based nanocarriers, so-called nanoplatforms, are the design of the targeted delivery systems such as liposomes, polymeric nanoparticles/micelles, nanoconjugates, norganic materials, carbon-based nanobiomaterials, and bioinspired phage system, which are based on the nanosize of 1–100 nm in diameter. In this review, the design and the application of these nanoplatforms are discussed at the cellular levels as well as in the clinics. We believe that this review can offer recent advances in the targeted delivery systems of nanobiomaterials regardingin vitroandin vivoapplications and the translation of nanobiomaterials to nanomedicine in anticancer therapy.

Targeted Delivery Systems

Cancer is still a leading cause of death worldwide, while most chemotherapies induce nonselective toxicity and severe systemic side effects. To address these problems, targeted nanoscience is an emerging field that promises to benefit cancer patients. Gold nanoparticles are nowadays in the spotlight due to their many well-established advantages. Gold nanoparticles are easily synthesizable in various shapes and sizes by a continuously developing set of means, including chemical, physical or eco-friendly biological methods. This review presents gold nanoparticles as versatile therapeutic agents playing many roles, such as targeted delivery systems (anticancer agents, nucleic acids, biological proteins, vaccines), theranostics and agents in photothermal therapy. They have also been outlined to bring great contributions in the bioimaging field such as radiotherapy, magnetic resonance angiography and photoacoustic imaging. Nevertheless, gold nanoparticles are therapeutic agents demonstrating its in vitro anti-angiogenic, anti-proliferative and pro-apoptotic effects on various cell lines, such as human cervix, human breast, human lung, human prostate and murine melanoma cancer cells. In vivo studies have pointed out data regarding the bioaccumulation and cytotoxicity of gold nanoparticles, but it has been emphasized that size, dose, surface charge, sex and especially administration routes are very important variables.

Osteoarthritis (OA) is a degenerative joint disease. An objective of the nanomedicine and drug delivery systems field is to design suitable pharmaceutical nanocarriers with controllable properties for drug delivery and site-specific targeting, in order to achieve greater efficacy and minimal toxicity, compared to the conventional drugs. The aim of this review is to present recent data on natural bioactive compounds with anti-inflammatory properties and efficacy in the treatment of OA, their formulation in lipid nanostructured carriers, mainly liposomes, as controlled release systems and the possibility to be intra-articularly (IA) administered. The literature regarding glycosaminoglycans, proteins, polyphenols and their ability to modify the cell response and mechanisms of action in different models of inflammation are reviewed. The advantages and limits of using lipid nanoformulations as drug delivery systems in OA treatment and the suitable route of administration are also discussed. Liposomes containing glycosaminoglycans presented good biocompatibility, lack of immune system activation, targeted delivery of bioactive compounds to the site of action, protection and efficiency of the encapsulated material, and prolonged duration of action, being highly recommended as controlled delivery systems in OA therapy through IA administration. Lipid nanoformulations of polyphenols were tested both in vivo and in vitro models that mimic OA conditions after IA or other routes of administration, recommending their clinical application.

Charge Reversal

Polymeric nanoparticles were widely used as delivery vehicles for targeted delivery of anticancer drugs, because of their targeting property and versatility. Mitochondria are one of the important organelles that regulate the apoptosis of cancer cells and can be considered as a pivotal target for cancer treatment. A pH-responsive charge-reversal and mitochondrial targeting nanoparticles, Vitamin B6-oligomeric hyaluronic acid-dithiodipropionic acid-berberine (B6-oHA-SS-Ber), were prepared in this study. Ber is a lipophilic cation that was conjugated with oHA through disulfide bonds to produce mitochondria-targeted conjugates (oHA-SS-Ber). B6 was conjugated to oHA to obtain B6-oHA-SS-Ber and the two types of Cur-loaded nanoparticles (Cur-NPs) were formulated by the dialysis method. Due to pKa of B6, the charge they carried in the tumor tissue acidic microenvironment can be transferred from negative charge to positive charge, further targeting mitochondria. In our study, we successfully synthesized B6-HA-SS-Ber and characterized the structure by 1H-NMR. According to the results of transmission electron microscopy (TEM), we found that the B6-oHA-SS-Ber/Cur micelles could self-assembled in water to form spherical nanoparticles, with a hydrodynamic diameter of 172.9±13 nm. Moreover, in vitro cytotoxicity, cellular uptake, lysosome escape and mitochondrial distribution researches revealed the better effect of B6-oHA-SS-Ber/Cur micelles in comparison to oHA-SS-Ber/Cur. In vivo anticancer activities indicated that the B6-oHA-SS-Ber/Cur micelles exhibited effective inhibition of tumor growth.

Brucellosis is a worldwide zoonosis caused by different species of the genus Brucella. The intracellular localisation of this pathogen, particularly in macrophages, renders treatment difficult since most antibiotics known to be efficient in vitro do not actively pass through cellular membranes. As alternative to current treatment, polymeric drug delivery systems containing gentamicin have been developed. These particulate carriers target the drug into the mononuclear-phagocytic system, where the pathogen resides that will allow intracellular accumulation of the antibiotic after particle degradation. Besides, particle uptake may induce macrophage activation, increasing the production of reactive oxygen intermediates, involved in host defense against the intracellular pathogen. The aim of the present work was to study the suitability of polymeric nanoparticles for gentamicin entrapment in view to treat brucellosis. Different poly(lactide-co-glycolide) PLGA polymers were used to formulate the nanoparticles containing gentamicin by a water-oil-water solvent evaporation method. Furthermore, in vitro macrophage activation upon nanoparticles phagocytosis and in vivo distribution of the nanocarriers in the target organs for Brucella (liver and spleen) were also studied. The nanoparticle sizes were below 350 nm, the gentamicin encapsulation efficiency depended on the polymer type used for their preparation and the in vitro release of the antibiotic exhibited a continuos pattern (PLGA 502H). PLGA 502H nanoparticles were the most suitable due to the highest entrapment and the most sustained release. The nanoparticles were successfully phagocyted by a J774 murine monocytes cell line and biodistribution studies in mice after intravenous administration of the delivery systems revealed that the particles reached the target organs of Brucella (liver and spleen). All together, these results indicate that the nanocarriers described in this work may be suitable as gentamicin delivery system to control brucellosis.

Background: Recent past decades have reported emerging of polymeric nanoparticles as a promising technique for controlled and targeted drug delivery. As nanocarriers, they have high drug loading and delivery to the specific site or targeted cells with an advantage of no drug leakage within en route and unloading of a drug in a sustained fashion at the site. These stimuli-responsive systems are functionalized in dendrimers, metallic nanoparticles, polymeric nanoparticles, liposomal nanoparticles, quantum dots. Purpose of Review: The authors reviewed the potential of smart stimuli-responsive carriers for therapeutic application and their behavior in external or internal stimuli like pH, temperature, redox, light, and magnet. These stimuli-responsive drug delivery systems behave differently in In vitro and In vivo drug release patterns. Stimuli-responsive nanosystems include both hydrophilic and hydrophobic systems. This review highlights the recent development of the physical properties and their application in specific drug delivery. Conclusion: The stimuli (smart, intelligent, programmed) drug delivery systems provide site-specific drug delivery with potential therapy for cancer, neurodegenerative, lifestyle disorders. As development and innovation, the stimuli-responsive based nanocarriers are moving at a fast pace and huge demand for biocompatible and biodegradable responsive polymers for effective and safe delivery.
