Orally Administrated Olsalazine-Loaded Multilayer Pectin/Chitosan/Alginate Composite Microspheres for Ulcerative Colitis Treatment.

The pathogenesis of inflammatory bowel diseases (IBDs) including ulcerative colitis (UC) and Crohn's disease is extremely cloudy. Maintaining the level of remission lesions in colitis is the default treatment attitude at present. Epithelial barrier restoration is considered as the same important strategy as colonic targeted drug delivery in UC treatment. In this paper, we developed a multilayer natural polysaccharide microsphere (pectin/chitosan/alginate) with pH and enzyme dual sensitivity to reduce the loss of medication in the upper digestive tract and preferentially adhere to exposed epithelial cells in colonic tissues by electrostatic forces for efficiently targeted UC treatment. Olsalazine as an inflammatory drug was efficiently loaded in the chitosan layer and realized a colonic pH-responsive drug release. Furthermore, the multilayer microspheres exhibited excellent capability in suppressing harmful flora and a bio-adhesion effect to extend the duration of local medicine. In the in vivo anti-colitis study, the downregulated levels of pro-inflammatory factors and the increase of tight junction protein indicated the excellent anti-inflammation effect of the olsalazine-loaded microspheres. In summary, these results showed that the multilayer natural polysaccharide microspheres could be a powerful candidate in the targeted drug delivery system for UC therapy.

Nano-Gels: Recent Advancement in Fabrication Methods for Mitigation of Skin Cancer

In the 21st century, melanoma and non-melanoma skin cancers have become an epidemic outbreak worldwide. Therefore, the exploration of all potential preventative and therapeutic measures based on either physical or bio-chemical mechanisms is essential via understanding precise pathophysiological pathways (Mitogen-activated protein kinase, Phosphatidylinositol 3-kinase Pathway, and Notch signaling pathway) and other aspects of such skin malignancies. Nano-gel, a three-dimensional polymeric cross-linked porous hydrogel having a diameter of 20-200 nm, possesses dual properties of both hydrogel and nanoparticle. The capacity of high drug entrapment efficiency with greater thermodynamic stability, remarkable solubilization potential, and swelling behavior of nano-gel becomes a promising candidate as a targeted drug delivery system in the treatment of skin cancer. Nano-gel can be either synthetically or architectonically modified for responding to either internal or external stimuli, including radiation, ultrasound, enzyme, magnetic, pH, temperature, and oxidation-reduction to achieve controlled release of pharmaceuticals and several bio-active molecules such as proteins, peptides, genes via amplifying drug aggregation in the active targeted tissue and reducing adverse pharmacological effects. Several drugs, such as anti-neoplastic biomolecules having short biological half-lives and prompt enzyme degradability capacity, must be appropriate for administration employing either chemically bridged or physically constructed nano-gel frameworks. The comprehensive review summarizes the advancement in the preparation and characterization methods of targeted nano-gel with enhanced pharmacological potential and preserved intracellular safety limits for the mitigation of skin malignancies with a special emphasize on skin cancer inducing pathophysiological pathways and prospective research opportunities for skin malignancy targeted nano-gels.

Advances in nanomaterial-based targeted drug delivery systems.

Nanomaterial-based drug delivery systems (NBDDS) are widely used to improve the safety and therapeutic efficacy of encapsulated drugs due to their unique physicochemical and biological properties. By combining therapeutic drugs with nanoparticles using rational targeting pathways, nano-targeted delivery systems were created to overcome the main drawbacks of conventional drug treatment, including insufficient stability and solubility, lack of transmembrane transport, short circulation time, and undesirable toxic effects. Herein, we reviewed the recent developments in different targeting design strategies and therapeutic approaches employing various nanomaterial-based systems. We also discussed the challenges and perspectives of smart systems in precisely targeting different intravascular and extravascular diseases.

Therapeutic potential of oxo-triarylmethyl (oxTAM) as a targeted drug delivery system for nitrosourea and fluorouracil anticancer drugs; A first principles insight

In this study, oxygenated triarylmethyl (oxTAM) is investigated by DFT calculations as a drug carrier framework for Nitrosourea (NU) and Fluorouracil (FU) drugs. Based on the adsorption analysis i.e., energies and distances between interacting atoms, it is found that oxTAM exhibits excellent carrier abilities for the delivery of FU (−1.53 eV & 2.00 Å) and NU (−1.33 eV & 2.12 Å) drugs. NCI and QTAIM results indicate the presence of hydrogen bonding in drug-carrier complexes. The values of dipole moment and global chemical descriptors show the significant reactivity of oxTAM for NU and FU drugs. Based on electronic property analysis, FU@oxTAM has a higher adsorption trend for complexation with oxTAM as compared to NU@oxTAM. Moreover, FU can easily release from the carrier due to the decreasing adsorption stability after protonation under an acidic environment as well as a short recovery time observed for the oxTAM carrier surface. Keeping in view all the above parameters, we inferred that oxTAM can serve as a potential drug delivery system for anticancer drugs including, Nitrosourea and Fluorouracil drugs.

NANOSPONGES - A REVOLUTIONARY TARGETED DRUG DELIVERY NANOCARRIER: A REVIEW

Effective targeted drug delivery systems have long been a dream, but have been largely hampered by the complex chemistries involved in developing new systems. The creation of novel colloidal carriers known as nanosponges has the potential to resolve these issues. An innovative and developing technology called nanosponge provides regulated medication delivery for topical application. Highly porous nanosponges have a unique capacity to entrap active molecules and have the advantage of programmable release. Nanosponges are small three-dimensional porous structures about the size of nanometer that can contain many different drugs. These tiny sponges can move throughout the body until they meet a specific target site and attach to surfaces and begin to release the drug in a controlled and predictable manner. Because the drug can be delivered to a specific target site instead of circulating throughout the body, it is more effective for a given specific dose. They are easy to make and safe for biological use. Different types of cyclodextrins can be cross-linked using a carbonyl or a dicarboxylate chemical as a cross-linker to create nanosponges. This groundbreaking technology has been extensively investigated for the delivery of medications for oral, topical, and parental administrations. Vaccines, antibodies, proteins, and enzymes can all be effectively transported via Nanosponges. The current review emphasizes the methods, advantages, disadvantages, characterization, and applications of nanosponges.

Enhanced Anti-Rheumatoid Arthritis Activity of Total Alkaloids from Picrasma Quassioides in Collagen-Induced Arthritis Rats by a Targeted Drug Delivery System

New drug delivery systems have rarely been used in the formulation of traditional Chinese medicine, especially those that are crude active Chinese medicinal ingredients. In the present study, hyaluronic acid decorated lipid-polymer hybrid nanoparticles were used to prepare a targeted drug delivery system (TDDS) for total alkaloid extract from Picrasma quassioides (TAPQ) to improve its targeting property and anti-inflammatory activity. Picrasma quassioides, a common-used traditional Chinese medicine (TCM), containing a series of hydrophobic total alkaloids including β-carboline and canthin-6-one alkaloids show great anti-inflammatory activity. However, its high toxicity (IC50= 8.088±0.903 μg/ml), poor water solubility (need to dissolve with 0.8% Tween-80) and poor targeting property severely limits its clinical application. Herein, hyaluronic acid (HA) decorated lipid-polymer hybrid nanoparticles loaded with TAPQ (TAPQ-NPs) were designed to overcome above mentioned deficiencies. TAPQ-NPs have good water solubility, strong anti-inflammatory activity and great joint targeting property. The in vitro anti-inflammatory activity assay showed that the efficacy of TAPQ-NPs was significantly higher than TAPQ(P<0.001). Animal experiments showed that the nanoparticles had good joint targeting property and had strong inhibitory activity against collagen-induced arthritis (CIA). These results indicate that the application of this novel targeted drug delivery system in the formulation of traditional Chinese medicine is feasible.

Dynamic analysis of small droplets at constant pressure and analytical model for drip systems and very low pressure drop-on-demand applications

We study the evolution of the growing volume of a droplet formed out of a capillary tube driven at a constant applied pressure by optical volume detection. A particular application aims at modeling the dynamic of the drop in the case of the injection of drugs in the middle-ear cavity using a small target drug delivery system. Various dispense tips such as a steel needle or silicone catheters and different t-BuOH aqueous solutions were used. A physical model based on the simplified Laplace–Young equation for a spherical droplet was developed to interpret the experimental results and model the observed deviation of the mean flow rate from the Poiseuille law when the drop radius is smaller than the capillary length. We emphasize the large influence of the surface tension which introduces a highly nonlinear effect at low applied pressure just above the capillary threshold pressure. The model fits well the evolution of the growing volume at various applied pressure up to a maximum diameter corresponding to the drop size close to the capillary length of the fluid, lc=γ/ρg, based on the liquid density ρ, gravity g and surface tension γ. We demonstrate that the model can also be applied to non spherical pendant droplets providing the apex elongation over the drop height of a spherical cap of the same volume is kept in a 30% range.

Abstract 829: Evaluation of SK-N-DZ CLENs as a potential drug delivery system for selective targeting of neuroblastoma cells

Abstract Background: Neuroblastoma (NB) is a malignancy of the neuroendocrine system affecting infants. NB is highly resistant to drug therapy, which leads to ineffective treatments and increased refractory. Current treatments have low specificity to targeted NB cells resulting in unwanted side effects. A drug delivery system that can overcome these problems is urgently needed. Incorporating drugs in optimized lipid nanoparticles such as liposomes have proven to be an effective method for drug targeting. To achieve better cellular selectivity, lipid membrane extract (LE) is derived from NB cells using a modified Dyer and Blight lipid extraction procedure. The objective of the study was to determine an optimized cell membrane lipid-extracted nanoliposomes (CLENs) for the NB cell model while considering physicochemical properties (i.e. size and molecular charge) and composition of the preparation. Methods: The neuroblastoma cell line, SK-N-DZ, was used for drug selectivity study. Expanded culture of SK-N-DZ was employed for cellular extraction purposes. The method for lipid membrane extraction was previously reported by Alharbi and Campbell, (AAPS Open 4,5(2018)). SK-N-DZ lipid extract was the main ingredient to prepare SK-N-DZ CLENs. Phase I of the study is to prepare CLENs with various compositions of DOPC, cholesterol, DPPE-PEG5000 and SK-N-DZ lipid extract. DPPE-Rhodamine was used for fluorescence and cellular uptake studies. Phase II of the study evaluated the effect of SK-N-DZ lipid extraction inclusion on drug incorporation, cellular uptake and selectivity, and cytotoxicity. Invitrogen alamarBlue HS in vitro assay was used to determine cell viability for cytotoxicity studies. SK-N-SH (brain tissue), BT-20 (breast tissue) and G401 (kidney tissue) cell lines served as negative controls. Results: The results from the cellular uptake optimization studies revealed that the optimized composition and ratio for SK-N-DZ CLENs was DOPC/Cholesterol/LE/PEG (65/10/20/5). The average particle size and value for zeta potential was 164 nm +/- 1.2 and -7.92 +/- 1.55 mV, respectively. The inclusion of SK-N-DZ lipid membrane extract (2, 10, 20 and 40 mol%) in preparation of CLENs increased cellular uptake by SK-N-DZ cells compared to corresponding control (no LE included). No difference observed in cellular uptake of preparations containing 20 and 40 mol% of LE. The additional inclusion of cholesterol (10, 20, 40 mol%) increased overall cellular uptake of preparations compared to CLENs without the additional cholesterol content. Overall, the inclusion of PEG (5, 10, and 20 mol%) in SK-N-DZ CLENs increased their uptake by the target cell population. Conclusion: In conclusion, the inclusion of SK-N-DZ lipid membrane extract in the nanoliposome preparations increased their overall cellular uptake by SK-N-DZ target cells. Additional cellular selectively and cytotoxicity studies are currently underway. Citation Format: Kevin Bumanglag, Thi Tran, Robert Campbell, Yishan Li.

Therapeutic efficiency of B3O3 quantum dot as a targeted drug delivery system toward Foscarnet anti-HIV drug

In this study, B3O3 quantum dot is investigated via density functional theory (DFT) calculations as an antiviral drug carrier toward Foscarnet. Geometric analysis is carried out to find stable orientations of interaction between Foscarnet drug and the B3O3 quantum dot. As a result, three stable orientations are proposed. The Eint of the most stable orientation is –32.63 kcal/mol whereas the BSSE corrected energy is −26.98 kcal/mol. Noncovalent interaction index (NCI) and quantum theory of atoms in molecules (QTAIM) analyses are employed to understand the nature and the type of interactions taking place between drug and the B3O3 quantum dot. Their results indicated the presence of hydrogen bonding in the most stable complex (orientation A). The HOMO-LUMO analysis is performed to study the electronic properties of the interacting moieties. The lowest Egap is observed in case of orientation A. The value of dipole moments and chemical descriptors showed the significant activity of B3O3 quantum dot toward Foscarnet drug molecule. The overall findings from this study suggest the B3O3 quantum dot as a potential drug carrier system for antiviral drugs.

Co-Delivery of Methotrexate and Nanohydroxyapatite with Polyethylene Glycol Polymers for Chemotherapy of Osteosarcoma

Neoadjuvant chemotherapy is an alternative treatment modality for tumors. Methotrexate (MTX) has been often used as a neoadjuvant chemotherapy reagent for osteosarcoma surgery. However, the large dosage, high toxicity, strong drug resistance, and poor improvement of bone erosion restricted the utilization of methotrexate. Here, we developed a targeted drug delivery system using nanosized hydroxyapatite particles (nHA) as the cores. MTX was conjugated to polyethylene glycol (PEG) through the pH-sensitive ester linkage and acted as both the folate receptor-targeting ligand and the anti-cancer drug due to the similarity to the structure of folic acid. Meanwhile, nHA could increase the concentration of calcium ions after being uptake by cells, thus inducing mitochondrial apoptosis and improving the efficacy of medical treatment. In vitro drug release studies of MTX-PEG-nHA in phosphate buffered saline at different pH values (5, 6.4 and 7.4) indicated that the system showed a pH-dependent release feature because of the dissolution of ester bonds and nHA under acidic conditions. Furthermore, the treatment on osteosarcoma cells (143B, MG63, and HOS) by using MTX-PEG-nHA was demonstrated to exhibit higher therapeutic efficacy. Therefore, the developed platform possesses the great potential for osteosarcoma therapy.

Cryo-Shocked Platelet Coupled with ROS-Responsive Nanomedicine for Targeted Treatment of Thromboembolic Disease.

Thrombolysis with tissue plasminogen activator (tPA) provides the most common therapy for ischemic stroke onset within the past 4.5 h. However, enhanced neutrophil infiltration and secondary blood-brain barrier injury caused by tPA administration have limited its therapeutic application, and tPA treatment is often accompanied by hemorrhagic transformation. To overcome the limitations of thrombolysis by tPA, maximize the therapeutic efficacy, and improve the safety, herein, we report a cryo-shocked platelet-based cell-hitchhiking drug delivery system, which consists of cryo-shocked platelet (CsPLT) and reactive oxygen species (ROS)-responsive liposomes loaded with thrombolytic tPA and anti-inflammation drug aspirin (ASA). CsPLT and liposomes were facilely conjugated via host-guest interactions. Under the guidance of CsPLT, it selectively accumulated in the thrombus site and quickly released the therapeutic payloads in response to the high ROS. tPA subsequently exhibited localized thrombolytic activity to suppress the expansion of thrombus, while ASA assisted in the inactivation of reactive astrogliosis, microglial/macrophage, and obstruction of neutrophil infiltration. This cryo-shocked platelet-hitchhiking tPA/ASA delivery system not only improves the thrombus-targeting efficiency of the two drugs for highly localized thrombolytic effects and anti-inflammation actions and platelets inactivation but also provides insights to the development of targeted drug delivery systems for thromboembolic disease treatment.

Review On Targeted Drug Delivery System And Its Carriers As Drug Targeted To A Specific Organ

Targeted delivery combined with controlled drug release has a pivotal function in the future of personalized medicine. Target drug delivery system is one of the most considerable novel approach towards drug delivery system.

Development and Evaluation of Crocetin-Functionalized Pegylated Magnetite Nanoparticles for Hepatocellular Carcinoma

Liver cancer remains among the leading causes of cancer-related deaths worldwide. This is due to many reasons, including limitations of available drugs, late diagnosis due to the overlapping symptoms with many other liver diseases, and lack of effective screening modalities. Compared to conventional chemotherapy, targeted drug delivery systems are advantageous in many ways, as they minimize drug resistance and improve therapeutic value for cancer patients. Nanomaterials, in general, and nanoparticles, in particular, possess nm size, which provides a high surface area for a great extent of functionalization to be used for the targeted delivery of cancer drugs. Amongst the different formulations of nanoparticles, magnetic nanoparticles (MNPs) have unique chemical and physical characteristics and magnetic behavior, making them preferable candidates as a core for drug delivery systems. To maintain the nanosized structure of MNPs, a polymeric coating is usually applied to maintain the nanoparticles dispersed in the solution. Moreover, the polymeric coating provides a plate form for carrying drug molecules on its surface. In the present study, poly(ethylene glycol) (PEG)-coated MNPs were successfully synthesized, where the optimum concentration of PEG on the surface of the MNPs was investigated. The PEG-coated MNPs were further coated with crocetin at different concentrations. The crocetin-coated pegylated MNPs were evaluated in vitro using a hepatic cell line (HepG2) for up to 72 h. Results showed good release kinetics under acidic and neutral conditions. The optimally prepared drug delivery system showed a high potential for reducing the HepG2 cell proliferation in vitro using an MTT assay. The calculated IC50 for Cro-PEG-MNPs were 0.1019, 0.0903, and 0.0462 mg/mL of 5×, 10× and 20×, respectively.

Dual-Ligand-Functionalized Liposomes Based on Glycyrrhetinic Acid and cRGD for Hepatocellular Carcinoma Targeting and Therapy.

Hepatocellular carcinoma (HCC) is one of the most common cancers, with high mortality. Chemotherapy is one of the main treatment options for HCC. However, the high toxicity and poor specificity of chemotherapeutic drugs have limited their clinical application. In this study, dual-ligand liposomes modified with glycyrrhetinic acid (GA) and cyclic arginine-glycine-aspartic acid (cRGD) (GA/cRGD-LP) were designed to target the GA receptor and αvβ3 integrin, respectively. The aim was to develop a highly selective targeted drug delivery system and further enhance the antitumor efficiency of drugs by targeting both hepatic tumor cells and vasculature. A novel lipid conjugate (mGA-DOPE) by coupling dioleoylphosphatidyl ethanolamine (DOPE) with methyl glycyrrhetinic acid (mGA) was synthesized, and its structure was confirmed. The targeting efficiency of GA/cRGD-LP by in vitro cellular uptake and ex vivo imaging was assessed. GA- and cRGD-modified doxorubicin-loaded liposomes (GA/cRGD-LP-DOX) were prepared, and their cytotoxicity in HepG2 and antitumor activity were evaluated. The results showed that the average particle size of the GA/cRGD-LP-DOX was 114 ± 4.3 nm, and the zeta potential was -32.9 ± 2.0 mV. The transmission electron microscopy images showed that the shapes of our liposomes were spherical. cGA/cRGD-LP-DOX displayed an excellent cellular uptake in both HepG2 and human umbilical vein endothelial cells. In the in vivo study, pharmacokinetic parameters indicated that cGA/cRGD-LP can prolong the circulation time of DOX in the blood. GA/cRGD-LP-DOX showed greater inhibition of tumor growth for HepG2-bearing mice than either the single-ligand-modified liposomes or nontargeted liposomes. GA/cRGD-LP-DOX displayed higher liver tumor localization than that of single-ligand-modified liposomes or free DOX. GA/cRGD-LP is a promising drug delivery system for liver cancer targeting and therapy and is worthy of further study.

Targeted delivery of nutraceuticals derived from food for the treatment of obesity and its related complications

Nutraceuticals which are abundant in foods have attracted much attention due to their bioactive activities of anti-obesity, anti-hyperlipidemia and anti-atherosclerosis. Unfortunately, the poor bioavailability severely undermines their envisioned benefits. Therefore, there is an urgent need to develop suitable delivery systems to promote the benefits of their biological activity. Targeted drug delivery system (TDDS) is a novel drug delivery system that can selectively concentrate drugs on targets in the body, improve the bioavailability of agents and reduce side effects. This emerging drug delivery system provides a new strategy for the treatment of obesity with nutraceuticals and would be a promising alternative to be widely used in the food field. This review summarizes the recent studies on the application in the targeted delivery of nutraceuticals for treating obesity and its related complications, especially the available receptors and their corresponding ligands for TDDS and the evaluation methods of the targeting ability.

A Review on Colon Targeted Drug Delivery System

Colon-specific drug delivery systems (CDDS) are advantageous for the treatment of a range of local diseases such as ulcerative colitis, Crohn’s disease, irritable bowel syndrome, chronic pancreatitis, and colonic cancer. Colon targeted drug delivery system can be utilized to deliver protein and peptide drugs as they that are known to degrade in the extreme gastric pH. These approaches involve the use of formulation components that interact with one or more aspects of gastrointestinal (GI) physiology, such as the variation in the pH along the GI tract, the occurrence of colonic microflora, and enzymes, to attain colon targeting. This article highlights the advantages, limitations and factors influencing colon-specific drug delivery. Further, the review gives information of various conventional, as well as relatively newer formulation approaches presently being utilized for the improvement of CDDS.

A Short Review on Recent Approches in Targeted Drug Dilvairy System (TDDS)

Targeted drug delivery is an advanced method of delivering drugs to patients in such a targeted order that increases the concentration of the delivered drug only on the body part of interest (organs/tissues/cells), which in turn improves the effectiveness of the treatment while reducing side effects of drug administration. Basically, drug targeting should help the drug molecule to preferentially reach the desired site. The inherent advantage of this technique results in the administration of the required drug with its reduced dose and reduced side effect. This inherent advantage of a targeted drug delivery system is also strongly recognized by research and development in the clinical and pharmaceutical fields as the backbone of therapeutics and diagnostics. Various drug carriers that can be used in this advanced delivery system are soluble polymers, biodegradable microsphere polymers (synthetic and natural), neutrophils, fibroblasts, artificial cells, lipoproteins, liposomes, micelles, and immune micelles. The goal of a targeted drug delivery system is to prolong, localize, target, and have a protected drug interaction with the diseased.

CHEMOTHERAPEUTIC DRUG DELIVERY SYSTEMS: NEW IDEAS AND PERSPECTIVES

Targeted medication delivery to the organ, tissue, or cells currently offers great opportunities in the field of drug therapy. Drug delivery systems (DDS) are essential for improving the efficacy of chemotherapy in cancer treatment. Chemotherapy is a subject of great interest since new drug delivery techniques are constantly being created. The ability of therapeutic agents to reach their intended sites and their low accumulation in non-specific sites (healthy organs and tissues) are both crucial components of anti-tumor chemotherapy success. As a result, the targeted distribution of medications to the organs, tissues, or cells is currently thought to provide wonderful prospective in the field of chemotherapy. The fundamental idea behind targeted delivery is that molecules that can be recognised by a specific receptor on cells or target sites can be used to modify delivery systems (such as the vector, containers, and others) rather than just the medication itself. These are therefore referred to as "targeted drug delivery systems." Yet, the development of multifunctional nanocarriers, such as nanoparticles, liposomes, micelles, dendrimers, and others, can greatly improve the effectiveness of numerous therapeutic and diagnostic procedures.

Utilization of Functionalized Metal–Organic Framework Nanoparticle as Targeted Drug Delivery System for Cancer Therapy

Cancer is a multifaceted disease that results from the complex interaction between genetic and environmental factors. Cancer is a mortal disease with the biggest clinical, societal, and economic burden. Research on better methods of the detection, diagnosis, and treatment of cancer is crucial. Recent advancements in material science have led to the development of metal-organic frameworks, also known as MOFs. MOFs have recently been established as promising and adaptable delivery platforms and target vehicles for cancer therapy. These MOFs have been constructed in a fashion that offers them the capability of drug release that is stimuli-responsive. This feature has the potential to be exploited for cancer therapy that is externally led. This review presents an in-depth summary of the research that has been conducted to date in the field of MOF-based nanoplatforms for cancer therapeutics.
