A polymer-based drug delivery system for the antineoplastic agent bis(maltolato)oxovanadium in mice.
Using vanadyl sulphate, sodium orthovanadate or bis(maltolato)oxovanadium (BMOV), Cruz TF, Morgan A, Min W (1995, Mol Cell Biochem 153: 161-166) have recently demonstrated the antineoplastic effects of vanadium in mice. In this study, the antineoplastic effects of BMOV against human tumour cell lines was confirmed, and this effect was shown to depend on the prolonged exposure of the cells to the drug. We have investigated a polymeric drug delivery system for the sustained delivery of BMOV as an antineoplastic agent in mice. The objective was to design and evaluate an injectable polymer-BMOV paste that would act as a drug implant for the slow but sustained release of BMOV in the mice. In vitro studies showed that the biodegradable polymer poly (Ghlr epsilon epsilon-caprolactone) (PCL) released BMOV in a sustained manner with rates of drug release increasing with increased loading of the drug in the polymer. In vivo studies showed that PCL-BMOV paste implants produced a concentration-dependent inhibition of MDAY-D2 tumour growth via systemic drug delivery. Further in vivo studies showed that 5% BMOV-loaded PCL (containing 20% methoxypolyethylene glycol) was effective in preventing tumour regrowth of resected RIF tumour masses in mice when the PCL-BMOV paste was applied to the resected site for localized drug delivery. The results confirm the potential of vanadium as an antineoplastic agent and show that the injectable PCL-BMOV formulation releases a chemotherapeutic dose of vanadium for the systemic treatment of whole tumours as well as the localized treatment of resected RIF tumours.

Virosomes can be used as vaccines and vehicles for the cellular transport of various macromolecular molecules. The potential for drug delivery and targeting systems to be implemented using virosomes represents an exciting area of research. Virosomes are biocompatible, biodegradable, nontoxic, and nonimmunogenic, so efforts have been made to utilize them as anti-inflammatory or adjuvant agents, as well as drug and organic delivery frameworks for therapeutic applications. The success of virosomal drug delivery depends on the strategy used to assemble and fuse typeable bioactive materials into virosomes. Potential innovations of virosomes could be used to transport peptides and nucleic acids or qualities and drugs such as antitoxins, anticancer agents, and steroids.

BackgroundPolymeric drug delivery systems have been achieved great development in the last two decades. Polymeric drug delivery has defined as a formulation or a device that enables the introduction of a therapeutic substance into the body. Biodegradable and bio-reducible polymers make the magic possible choice for lot of new drug delivery systems. The future prospects of the research for practical applications has required for the development in the field.Main bodyNatural polymers such as arginine, chitosan, dextrin, polysaccharides, poly (glycolic acid), poly (lactic acid), and hyaluronic acid have been treated for polymeric drug delivery systems. Synthetic polymers such as poly (2-hydroxyethyl methacrylate), poly(N-isopropyl acrylamide)s, poly(ethylenimine)s, dendritic polymers, biodegradable and bio-absorbable polymers have been also discussed for polymeric drug delivery. Targeting polymeric drug delivery, biomimetic and bio-related polymeric systems, and drug-free macromolecular therapeutics have also treated for polymeric drug delivery. In polymeric gene delivery systems, virial vectors and non-virial vectors for gene delivery have briefly analyzed. The systems of non-virial vectors for gene delivery are polyethylenimine derivatives, polyethylenimine copolymers, and polyethylenimine conjugated bio-reducible polymers, and the systems of virial vectors are DNA conjugates and RNA conjugates for gene delivery.ConclusionThe development of polymeric drug delivery systems that have based on natural and synthetic polymers are rapidly emerging to pharmaceutical fields. The fruitful progresses have made in the application of biocompatible and bio-related copolymers and dendrimers to cancer treatment, including their use as delivery systems for potent anticancer drugs. Combining perspectives from the synthetic and biological fields will provide a new paradigm for the design of polymeric drug and gene delivery systems.

Nanotechnology has profound applications in healthcare and has improved healthcare research to a large extent. The therapeutic benefits of nanotechnology in the field of medicine have resulted in new areas, such as nanomedicine, nanobiotechnology, etc. Researchers in the field are attempting to find an effective nanoformulation to deliver growth factors, supplements or drugs safely and in a sustained manner at the required site. Their task is to attempt a different drug nanoformulation of existing blockbuster drugs that brings improved efficacy and a therapeutic breakthrough. Thus the ultimate objective of these nanotechnological drug-delivery systems is to fine tune the normal profile of potent drug molecules in the body following their administration to significantly improve their efficacy and also minimize potential intrinsic severe adverse effects. For treatment of breast cancer and non-small-cell lung cancer, Abraxane ® (paclitaxel) is employed as a nanoparticular formulation, which increases drug delivery up to 70% in comparison with solvent-based paclitaxel delivery. In this novel nanoformulation, Abraxis Bio Sciences have used Bristol-Meyers Squibb’s blockbuster drug paclitaxel (Taxol) and a very common globular protein bovine serum albumin (BSA). There are numerous nanotechnology-based drug-delivery systems such as nanocrystals, nanoemulsions, lipid or polymeric nanoparticles, liposomes and nanofibers. While nanoemulsions and liposomal formulations did not make significant advances, despite huge research spending, the polymeric nanoparticulate systems show more promise. Nanoparticles of a polymeric nature find application as drug-delivery systems and are advantageous due to their scalability, cost, controlled and targeted delivery, compatibility, degradability, etc. Natural biopolymers are even better than the synthetic polymers in terms of biocompatibility and biodegradability. Nanoparticulate drug formulations alter the pharmokinetic profile of the therapeutic entity and program the release of the drug in sustained or controlled manner. Thus, nanoparticle or nanoformulated drugs outperform conventional systemic delivery in terms of delivery of an encapsulated drug and its sustained release. Slowly and surely nanoformulated drugs are coming onto the market, surpassing systemic delivery, which is believed to be the only mode of administration for a wide range of active pharmaceutical ingredients. Nanofibrous drug-delivery systems are being developed as potential scaffolds in tissue regeneration, wound healing and cancer drug-delivery applications. In this chapter we are going to discuss two promising nanotechnology-based drug-delivery tools, namely electrospun micro- and nanofibers and electrosprayed micro- and nanoparticles, which have a common synthetic procedure mediated by an electrical potential difference.

In the past years, alternative pharmaceutical formulations of anti-cancer agents have been investigated in order to improve conventional chemotherapy treatment. In conventional/current therapy oral tablet, capsule and injectable formulations are used for anti-cancer drugs delivery. These formulations associated with problems like severe toxic side effects on healthy organs, difficulties in clinical administration, drug resistance and limited access of the drug to the tumor sites suggested the need to focus on site specific controlled drug delivery systems. Novel drug delivery systems are capable of controlling the rate of drug delivery, sustaining the duration of therapeutic activity and targeting the drug to the disease tissue leading to better therapeutic effect with minimum side effects. In this review, we have explored the literature related to recent development in delivery of anti-cancer drugs identify problems in present conventional chemotherapy and detailed newer approaches and future development in the delivery of anti-cancer drugs.

Simple SummaryApplication of drug delivery systems (DDS) in oncology may increase the effectiveness of cancer treatment and reduce the associated adverse side effects. Although various biomaterials can be considered for the development of DDS, the materials of natural origin offer great biocompatibility and degradability. Silk is a natural biomaterial with exceptional properties, and one of them is the possibility to form diverse morphological structures. Scaffolds, films, hydrogels, fibers, foams spheres, capsules, microneedles, among others, can be used for local and systemic drug delivery. In this review, we described the various silk-based DDS for potential application in oncology. However, the unique silk properties combined with the possibility of their further modifications and blending open the gate to numerous potential biomedical applications, not only in the oncology field.For years, surgery, radiotherapy, and chemotherapy have been the gold standards to treat cancer, although continuing research has sought a more effective approach. While advances can be seen in the development of anticancer drugs, the tools that can improve their delivery remain a challenge. As anticancer drugs can affect the entire body, the control of their distribution is desirable to prevent systemic toxicity. The application of a suitable drug delivery platform may resolve this problem. Among other materials, silks offer many advantageous properties, including biodegradability, biocompatibility, and the possibility of obtaining a variety of morphological structures. These characteristics allow the exploration of silk for biomedical applications and as a platform for drug delivery. We have reviewed silk structures that can be used for local and systemic drug delivery for use in cancer therapy. After a short description of the most studied silks, we discuss the advantages of using silk for drug delivery. The tables summarize the descriptions of silk structures for the local and systemic transport of anticancer drugs. The most popular techniques for silk particle preparation are presented. Further prospects for using silk as a drug carrier are considered. The application of various silk biomaterials can improve cancer treatment by the controllable delivery of chemotherapeutics, immunotherapeutics, photosensitizers, hormones, nucleotherapeutics, targeted therapeutics (e.g., kinase inhibitors), and inorganic nanoparticles, among others.
