Abstract
The protein delivery system is one of the innovative or novel drug delivery systems in the present era. Proteins play an indispensable role in our body and are mainly found in every part, like tissue and cells of our body. It also controls various functions, such as maintaining our tissue, transportation, muscle recovery, enzyme production and acting as an energy source for our body. Protein therapeutics have big future perspectives, and their use in the treatment of a wide range of serious diseases has transformed the delivery system in the pharmaceutical and biotechnology industries. The chief advantage of protein delivery is that it can be delivered directly to the systemic circulation. So far, parenteral routes, such as intravenous, intramuscular, and subcutaneous, are the most often used method of administering protein drugs. Alternative routes like buccal, oral, pulmonary, transdermal, nasal, and ocular routes have also shown a remarkable success rate. However, as with all other types of delivery, here, several challenges are posed due to the presence of various barriers, such as the enzymatic barrier, intestinal epithelial barrier, capillary endothelial barrier, and blood-brain barrier. There are several approaches that have been explored to overcome these barriers, such as chemical modification, enzymatic inhibitors, penetration enhancers, and mucoadhesive polymers. This review article discusses the protein, its functions, routes of administration, challenges, and strategies to achieve ultimate formulation goals. Recent advancements like the protein Pegylation method and Depofoam technology are another highlight of the article.

Abstract
Nanoparticle self-assembly in solution has gained immense interest due to the enhanced optical, chemical, magnetic, and electrical properties which manifest at the macroscale. Material properties in bulk are a direct consequence of the morphology of these nanoparticles in solutions. Precise control on the orientation, spatial arrangement, shape, size, composition, and control over the interactions of individual nanoparticles play a key role in enhancing their properties. While previous studies have used asymmetry in the nanoparticle and/or the use of linker grafts, nanoparticles grafted with polyelectrolyte grafts provide us a wide parameter space to control and tune their self-assembly in solutions. In this study, we have performed coarse-grained molecular dynamics simulations to understand the charge-driven self-assembly of spherical nanoparticles grafted with polyelectrolyte chains. Nanoparticles grafted with either positively or negatively charged polyelectrolyte chains self-assemble to different structures driven by both excluded volume and electrostatic interactions. Our study shows that by tuning the graft density, the chain length, and the charge density of the grafts, we could build and control a variety of self-assembled structures ranging from rings, dimers, strings, coil-like aggregates, and disordered-to-ordered aggregates.

Abstract
D-α-Tocopheryl polyethylene glycol 1000 succinate (TPGS) has shown potential applications in cancer therapy owing to its attractive properties, including reversal of multi-drug resistance and synergistic effects with antitumor drugs. However, its associated shortcomings cannot be underestimated, including activation of the body's immune response and acceleration of blood clearance of polyethylene glycolylated preparations. Polysialic acid (PSA) is a polysaccharide homopolymer, with the dual function of immune camouflage and tumor targeting. PSA and TPGS conjugates (PSA-TPGS) were synthesized to weaken the immune risks of TPGS. We developed PSA-TPGS and TPGS self-assembled mixed micelles and encapsulated the classical antineoplastic, docetaxel. The particle size of docetaxel-loaded mixed micelles was 16.3 ± 2.0 nm, with entrapment efficiency of 99.0 ± 0.9% and drug-loading efficiency of 3.20 ± 0.03%. Antitumor activity studies revealed that the mixed micelles showed better tumor inhibition than Tween 80 and TPGS micelles. Detection of the accelerated blood clearance (ABC) phenomenon demonstrated that insertion of PSA-TPGS into the micelles weakened the ABC phenomenon induced by TPGS. In summary, PSA-TPGS could be a potential nanocarrier to improve antitumor activity and weaken immune responses.

Abstract
Reports of marine organisms ingesting microplastics-formed from large plastic litter drifting in the marine environment by mechanical forces such as waves and photochemical processes initiated by sunlight, particularly ultraviolet rays-are increasing. However, the degradation process from microplastics to nanoplastics that are easily consumed by plankton located in the lower part of the food chain is not clear. Therefore, 200 nm diameter polystyrene (PS) latex particles-nanoparticle tracking analysis (NTA) calibration particles-dispersed in ultrapure deionized water were subjected to three types of agitation: rotation mixing, shaking, and flowing in addition to standing without agitation, and the physical degradation caused by agitation for 1 week at room temperature (23 °C) was evaluated. The degradation of the particles into nanosized particles was assessed by particle size distribution measurement using NTA and shape observation using field emission scanning electron microscopy (FE-SEM). In addition, the ratio of particle aggregation during incubation was calculated from the number of particles present in the region exceeding the particle size distribution range of the monodisperse particles before agitation with respect to the total number of particles. A shape change to a particle size of 100 nm or less was observed for the rotating and flowing of samples, and the influence of aggregation was suppressed to within 21% of the total particles calculated by NTA at the maximum. These results show that chemically stable PS can be degraded from micro- to nanosize with simple agitation in ultrapure deionized water.

Abstract
Vectorization has experienced significant development over the last few years and has been used to control the distribution of active ingredients to a target by their association with a vector. However, controlled drug delivery suffers from "burst release" as the drugs are released before the targeted site. Very few studies have examined the collective mechanisms of fission-fusion on micelles in the transport and expulsion of active ingredients. Endocytosis and exocytosis of cells are examples of fusion and fission in biological matter. Understanding these dynamics becomes crucial for the design and the control of new materials and new processes effective in controlled drug delivery. In this work, a study of the exchange dynamics between amphiphilic block copolymers and lipid membranes for vectorization of hydrophobic molecules using a fluorescence technique is presented. A highly hydrophobic alkylated pyrene, PyC18, is used as a fluorescent probe that can be exchanged between amphiphilic block copolymer micelles and liposomes via different mechanisms. It is demonstrated that the exchange dynamics evaluated for different liposome concentrations is a collective mechanism characterized by having two rate constants.

Abstract
Peptide and protein drugs, which are categorized as biologics, exhibit poor membrane permeability. This pharmacokinetic disadvantage has largely restricted the development of noninvasive dosage forms of biologics that deliver into systemic circulation. We have been investigating the potential use of cell-penetrating peptide-linked polymers as a novel absorption enhancer to overcome this challenge. Since our previous study revealed that biocompatible poly( N-vinylacetamide- co-acrylic acid) modified with d-octaarginine, a typical cell-penetrating peptide, enhanced in vitro permeation of biomolecules such as plasmid DNA and bovine serum albumin through cell membranes, the present study evaluated whether the polymers enhanced in vivo absorption of biologics applied on the mucosa. Mouse experiments demonstrated that d-octaarginine-linked polymers drastically enhanced nasal absorption of exendin-4, whose injection is clinically used. The mean bioavailability was 20% relative to subcutaneous administration, even though it fell short of 1% when exendin-4 alone was administered nasally. The absorption-enhancing function of the polymers was superior to that of sodium caprate and sodium N-(8-(2-hydroxybenzoyl)amino) caprylate, which have been used for humans as an absorption enhancer. In vitro experiments using several biologics with different characteristics revealed that biologics interacted with d-octaarginine-linked polymers and were taken up into cells when incubated with the polymers. The interaction and cellular uptake were enhanced as molecular weights of the biologics increased; however, their charge-dependent in vitro performance was not clearly observed. The current data suggested that biologics formulated with our polymers became an alternative to their conventional invasive parenteral formulations.

Abstract
A kind of polymeric lipid vesicles (PLVs) with pH-responsive turning on-off membrane for programed delivery of insulin in gastrointestinal (GI) tract was developed, which was self-assembled from the grafted amphipathic polymer of N-tocopheryl-N'-succinyl-ɛ-poly-l-lysine (TP/SC-g-PLL). By controlling the grafting ratio of hydrophobic alkane and ionizable carboxyl branches, the permeability of membrane was adjustable and thus allowing insulin release in a GI-pH dependent manner. The effects of grafting degree of substitution (DS) on the pH-responsive behavior of the formed vesicles were confirmed by critical aggregation concentration determination, morphology and size characterization. Their transepithelial permeability across the GI tract was proved by both confocal visualization in vitro model of Caco-2 cellular monolayer and in vivo hypoglycemic study in diabetic rats. Accordingly, the work described here indicated that the self-assembled PLVs could be a promising candidate for improving the GI delivery of hydrophilic biomacromolecule agents.

Abstract
In the modern world, a number of therapeutic proteins such as vaccines, antigens, and hormones are being developed utilizing different sophisticated biotechnological techniques like recombinant DNA technology and protein purification. However, the major glitches in the optimal utilization of therapeutic proteins and peptides by the oral route are their extensive hepatic first-pass metabolism, degradation in the gastrointestinal tract (presence of enzymes and pH-dependent factors), large molecular size and poor permeation. These problems can be overcome by adopting techniques such as chemical transformation of protein structures, enzyme inhibitors, mucoadhesive polymers and permeation enhancers. Being invasive, parenteral route is inconvenient for the administration of protein and peptides, several research endeavors have been undertaken to formulate a better delivery system for proteins and peptides with major emphasis on non-invasive routes such as oral, transdermal, vaginal, rectal, pulmonary and intrauterine. This review article emphasizes on the recent advancements made in the delivery of protein and peptides by a non-invasive (peroral) route into the body.

The objective of this study was to improve the efficacy of a natural compound tetrandrine against cancer by designing surfactant-free poly(lactic-co-glycolic acid) (PLGA) nanoparticles as drug carriers for tetrandrine. Nanoparticles were prepared from PLGA via the nano-precipitation method with or without the presence of surfactant poly(vinyl alcohol) (PVA) to encapsulate tetrandrine. Tetrandrine-loaded surfactant-free PLGA nanoparticles had an average particle size of 169.3 nm and morphology similar to the PLGA nanoparticles prepared using PVA as the surfactant. Tetrandrine-loaded surfactant-free PLGA nanoparticles could retard drug release in phosphate buffered saline (PBS) at pH 7.4 and the cumulative release of tetrandrine reached up to 68.33% over a period of 120 h. A549 cell line was used as the model cancer cells to investigate anticancer capability of tetrandrine-loaded surfactant-free PLGA nanoparticles via apoptosis assay, cytotoxicity and lysosome injury studies. The results showed that tetrandrine-loaded surfactant-free PLGA nanoparticles could effectively reduce cell viability and synergistically enhance tetrandrine-induced cell apoptosis.

Abstract
To understand the size effect of polymeric micelles on their biological properties, such as cellular uptake, biodistribution, tumor accumulation, and so on, we prepared a series of doxorubicin (DOX)-loaded protoporphyrin (PP)-poly(ε-caprolactone) (PCL)-poly(ethylene glycol) (PEG) micelles with different diameters (40, 70, 100, and 130 nm). The incorporation of the protoporphyrin moiety enhanced the stability of the micelles and provided luminescent capability that is useful in the investigation of the cellular uptake of the micelles by fluorescence imaging. The biodistributions of the micelles in mice bearing tumors were evaluated by near-infrared fluorescence imaging and DOX concentration measurements in different tissues. The in vitro and in vivo investigations demonstrated the pronounced dependence of the cellular uptake, biodistribution, and antitumor effectiveness of the micelles on their size.

Abstract
Alginate-dextran sulfate-based particles obtained by emulsification/internal gelation technology can be considered suitable carriers for oral insulin delivery. A rational study focused on the emulsification and particle recovery steps was developed in order to reduce particles to the nanosize range while keeping insulin bioactivity. There was a decrease in size when ultrasonication was used during emulsification, which was more pronounced when a cosurfactant was added. Ultrasonication add-on after particle recovery decreased aggregation and led to a narrower nanoscale particle-size distribution. Insulin encapsulation efficiency was 99.3%±0.5%, attributed to the strong pH-stabilizing electrostatic effect between insulin and nanoparticle matrix polymers. Interactions between these polymers and insulin were predicted using molecular modeling studies through quantum mechanics calculations that allowed for prediction of the interaction model. In vitro release studies indicated well-preserved integrity of nanoparticles in simulated gastric fluid. Circular dichroism spectroscopy proved conformational stability of insulin and Fourier transform infrared spectroscopy technique showed rearrangements of insulin structure during processing. Moreover, in vivo biological activity in diabetic rats revealed no statistical difference when compared to nonencapsulated insulin, demonstrating retention of insulin activity. Our results demonstrate that alginate-dextran sulfate-based nanoparticles efficiently stabilize the loaded protein structure, presenting good physical properties for oral delivery of insulin.

Abstract
UNLABELLED We are investigating an imaging agent that detects early-stage primary colorectal cancer on the mucosal surface in real time under colonoscopic observation. The imaging agent, which is named the nanobeacon, is fluorescent nanospheres conjugated with peanut agglutinin and poly(N-vinylacetamide). Its potential use as an imaging tool for colorectal cancer has been thoroughly validated in numerous studies. Here, toxicities of the nanobeacon were assessed in rats. The nanobeacon was prepared according to the synthetic manner which is being established as the Good Manufacturing Practice-guided production. The rat study was performed in accordance with Good Laboratory Practice regulations. No nanobeacon treatment-related toxicity was observed. The no observable adverse effect levels (NOAEL) of the nanobeacon in 7-day consecutive oral administration and single intrarectal administration were estimated to be more than 1000mg/kg/day and 50mg/kg/day, respectively. We concluded that the nanobeacon could be developed as a safe diagnostic agent for colonoscopy applications. FROM THE CLINICAL EDITOR Colon cancer remains a major cause of death. Early detection can result in early treatment and thus survival. In this article, the authors tested potential systemic toxicity of coumarin 6-encapsulated polystyrene nanospheres conjugated with peanut agglutinin (PNA) and poly(N-vinylacetamide) (PNVA), which had been shown to bind specifically to colonic cancer cells and thus very promising in colonoscopic detection of cancer cells.

Abstract
Polymeric micelles are nanostructures formed by the self-aggregation of copolymeric amphiphiles above the critical micellar concentration. Due to the flexibility to tailor different molecular features, they have been exploited to encapsulate motley poorly-water soluble therapeutic agents. Moreover, the possibility to combine different amphiphiles in one single aggregate and produce mixed micelles that capitalize on the features of the different components substantially expands the therapeutic potential of these nanocarriers. Despite their proven versatility, polymeric micelles remain elusive to the market and only a few products are currently undergoing advanced clinical trials or reached clinical application, all of them for the therapy of different types of cancer and administration by the intravenous route. At the same time, they emerge as a nanotechnology platform with great potential for non-parenteral mucosal administration. However, for this, the interaction of polymeric micelles with mucus needs to be strengthened. The present review describes the different attempts to develop mucoadhesive polymeric micelles and discusses the challenges faced in the near future for a successful bench-to-bedside translation.

Abstract
Many therapeutic proteins exert their pharmaceutical action inside the cytoplasm or onto individual organelles inside the cell. Intracellular protein delivery is considered to be the most direct, fastest and safest approach for curing gene-deficiency diseases, enhancing vaccination and triggering cell transdifferentiation processes, within other curative applications. However, several hurdles have to be overcome. For this purpose the use of polymers, with their ease of modification in physical and chemical properties, is attractive in protein drug carriers. They can protect their therapeutic protein cargo from degradation and enhance their bioavailability at targeted sites. In this chapter, potential and currently used polymers for fabrication of protein delivery systems and their applications for intracellular administration are discussed. Special attention is given to the use of cationic polymers for their ability to promote the cellular uptake of therapeutic proteins.

Abstract
We have been investigating an imaging agent that enables real-time and accurate diagnosis of early colorectal cancer at the intestinal mucosa by colonoscopy. The imaging agent is peanut agglutinin-immobilized polystyrene nanospheres with surface poly(N-vinylacetamide) chains encapsulating coumarin 6. Intracolonically-administered lectin-immobilized fluorescent nanospheres detect tumor-derived changes through molecular recognition of lectin for the terminal sugar of cancer-specific antigens on the mucosal surface. The focus of the present study was to evaluate imaging abilities of the nanospheres in animal models that reflect clinical environments. We previously developed an orthotopic mouse model with human colorectal tumors growing on the mucosa of the descending colon to better resemble the clinical disease. The entire colon of the mice in the exposed abdomen was monitored in real time with an in vivo imaging apparatus. Fluorescence from the nanospheres was observed along the entire descending colon after intracolonical administration from the anus. When the luminal side of the colon was washed with phosphate-buffered saline, most of the nanospheres were flushed. However, fluorescence persisted in areas where cancer cells were implanted. Histological evaluation demonstrated that tumors were present in the mucosal epithelia where the nanospheres fluoresced. In contrast, no fluorescence was observed when control mice, without tumors were tested. The lectin-immobilized fluorescent nanospheres were tumor-specific and remained bound to tumors even after vigorous washing. The nanospheres nonspecifically bound to normal mucosa were easily removed through mild washing. These results indicate that the nanospheres combined with colonoscopy, will be a clinically-valuable diagnostic tool for early-stage primary colon carcinoma.

Abstract
In this paper a novel copolymer, chitosan graft glyceryl monooleate (CS-GO) was synthesized and its potential as the nanocarrier for enhancing the peroral delivery of enoxaparin was studied systemically. The successful synthesis was characterized by (1)H NMR. Enoxaparin nanocomplexes were prepared by self-assembly. Mucoadhesive properties of the nanocomplexes were evaluated using mucin particle method. Uptake and transport of the nanocomplexes were investigated in Caco-2 cells. In vivo absorption was studied in rats. The therapeutic effects of the nanocomplexes were evaluated using pulmonary thromboembolism model in mice. This study demonstrated that compared to chitosan based system, hydrophobic modification of CS with GO enhanced the oral absorption of enoxaparin significantly, which is in good agreement with the enhanced mucoadhesion, cellular internalization and transport in cell culture. Cellular uptake of CS-GO based enoxaparin nanocomplexes was incubation time, enoxaparin concentration and incubation temperature dependent. The uptake mechanism was assumed to be adsorptive endocytosis via clathrin- and caveolae-mediated process. Its therapeutic efficacy was further demonstrated by pharmacodynamic study with pulmonary thromboembolism inhibition percentage 47.1%. In conclusion, CS-GO copolymer is a promising nanocarrier for enhancing the oral absorption of enoxaparin.

Abstract
OBJECTIVE This work deals with the preparation, characterization and in vitro release study of IBU-loaded gel graft copolymer nanoparticles. METHOD Gelatin (Gel) graft copolymer nanoparticles were prepared using styrene (Sty) and/or 2-hydroxyethyl methacrylate (HEMA) monomers in the presence of potassium persulfate and glutaraldehyde as an initiator and cross-linker, respectively. The prepared nanoparticles as sustained release drug carriers were investigated using the nonsteriodal anti-inflammatory model drug, ibuprofen (IBU). RESULTS The prepared nanoparticles as sustained release drug carriers were investigated using the nonsteriodal anti-inflammatory model drug, IBU. The prepared Gel/HEMA and Gel/Sty nanoparticles exhibited particles size ranging from 15 to 17 nm and from 0.42 to 5 mm, respectively. The dissolution of IBU in phosphate buffer, pH 7.4, at 37°C from the prepared nanoparticles was evaluated using UV spectroscopy. In addition, the prepared nanoparticles were characterized using Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), transmitting electron microscope (TEM) and zeta potential/particle size analyzer. In vitro dissolution study showed that the dissolution rates of the crosslinked nanoparticles were retarded relative to the uncrosslinked ones. Moreover, the released amount constantly decreases with increasing gluteraldehyde content in the gel nanoparticles. CONCLUSION Crosslinked gel-based graft copolymers exhibited slow IBU release within six hours. Furthermore, results from different characterization techniques such as TEM, particles size and zeta potential measurements confirmed the formation of pH-responsive gel-graft copolymer nanoparticles.

The surface of the nanosphere was modified with peanut agglutinin (PNA) and poly(N-vinylacetamide (PNVA) moieties. The former binds to Gal-β(1-3)GalNAc with high affinity while the latter enhances the specificity of PNA for the carbohydrates. The specificity of the nanobeacon was evaluated in human colorectal cancer cells and specimens, and the data were compared with immunohistochemical staining and flow cytometric analysis. Additionally, distribution of the nanobeacon in vivo was assessed using an "intestinal loop" mouse model. Quantitative analysis of the data indicated that approximately 2 μg of PNA were detected for each milligram of the nanobeacon. The nanobeacon specifically reported colorectal tumors by recognizing the tumor-specific antigen through the surface-immobilized PNA. Removal of TF from human colorectal cancer cells and tissues resulted in a loss of fluorescence signal, which suggests the specificity of the probe. Most importantly, the probe was not absorbed systematically in the large intestine upon topical application. As a result, no registered toxicity was associated with the probe. These data demonstrate the potential use of this novel nanobeacon for imaging the TF antigen as a biomarker for the early detection and prediction of the progression of colorectal cancer at the molecular level.

Abstract
We evaluated the potential of poly(N-vinylacetamide-co-acrylic acid) modified with d-octaarginine, which is a typical cell-penetrating peptide, as a carrier for mucosal vaccine delivery. Mice were nasally inoculated four times every seventh day with PBS containing ovalbumin with or without the d-octaarginine-linked polymer. The polymer enhanced the production of ovalbumin-specific immunoglobulin G (IgG) and secreted immunoglobulin A (IgA) in the serum and the nasal cavity, respectively. Ovalbumin internalized into nasal epithelial cells appeared to stimulate IgA production. Ovalbumin transferred to systemic circulation possibly enhanced IgG production. An equivalent dose of the cholera toxin B subunit (CTB), which was used as a positive control, was superior to the polymer in enhancing antibody production; however, dose escalation of the polymer overcame this disadvantage. A similar immunization profile was also observed when ovalbumin was replaced with influenza virus HA vaccines. The polymer induced a vaccine-specific immune response identical to that induced by CTB, irrespective of the antibody type, when its dose was 10 times that of CTB. Our cell-penetrating peptide-linked polymer is a potential candidate for antigen carriers that induce humoral immunity on the mucosal surface and in systemic circulation when nasally coadministered with antigens.

Abstract
Oleoyl-carboxymethy chitosan (OCMCS) nanoparticles based on chitosan with different molecular weights (50, 170 and 820 kDa) were prepared by self-assembled method. The nanoparticles had spherical shape, positive surface charges and the mean diameters were 157.4, 274.1 and 396.7 nm, respectively. FITC-labeled OCMCS nanoparticles were internalized via the intestinal mucosa and observed in liver, spleen, intestine and heart following oral deliverance to carps (Cyprinus carpio). Extracellular products (ECPs) of Aeromonas hydrophila as microbial antigen was efficiently loaded to form OCMCS-ECPs nanoparticles and shown to be sustained release in PBS. Significantly higher (P < 0.05) antigen-specific antibodies were detected in serum after orally immunized with OCMCS-ECPs nanoparticles than that immunized with ECPs alone and non-immunized in control group in carps. These results implied that amphiphilic modified chitosan nanoparticles had great potential to be applied as carriers for the oral administration of protein drugs.

Abstract
INTRODUCTION Over the past years, temperature and pH-sensitive hydrogels was developed as suitable carriers for drug delivery. In this study temperature and pH-sensitive hydrogels was designed for an oral insulin delivery modeling. METHODS NIPAAm-MAA -HEM copolymers were synthesized by radical chain reaction with 86:4:10 (5% w/v) ratios respectively. Reaction was carried out in 1,4-Dioxane under Nitrogen gas-flow. The copolymers were characterized with FT-IR, 1H-NMR and DSC. Copolymers were loaded with regular insulin by modified double emulsion method with ratio of 1:10. Release study carried out in two different pH (pH=2 and 7.4 for stomach and intestine simulation respectively) at 37ºC. For each pH, a 5 mL suspension of the insulin containing hydrogel was taken in to a cellulose acetate dialysis membrane, and the dialysis membrane was allowed to float in a beaker containing 15 mL of buffer solution. The beakers were placed in a shaker incubator maintained at 37ºC. Phosphate buffer (0.1 M, pH 3)/ acetonitrile (60/40) was used as the mobile phase in HPLC assay. RESULTS Yield of reaction was 86% with an optimum Lower Critical Solution Temperature point (30ºC). In-vitro studies showed a control release behavior via pH changes which the amount of insulin releases was 80% and 20% at pH=2 and 7.4 respectively. CONCLUSION Results showed that by optimizing polymerization and loading method we could achieve a suitable nano system for oral delivery of insulin.

Abstract
Till recent, injections remained the most common means for administering therapeutic proteins and peptides because of their poor oral bioavailability. However, oral route would be preferred to any other route because of its high levels of patient acceptance and long term compliance, which increases the therapeutic value of the drug. Designing and formulating a polypeptide drug delivery through the gastro intestinal tract has been a persistent challenge because of their unfavorable physicochemical properties, which includes enzymatic degradation, poor membrane permeability and large molecular size. The main challenge is to improve the oral bioavailability from less than 1% to at least 30-50%. Consequently, efforts have intensified over the past few decades, where every oral dosage form used for the conventional small molecule drugs has been used to explore oral protein and peptide delivery. Various strategies currently under investigation include chemical modification, formulation vehicles and use of enzyme inhibitors, absorption enhancers and mucoadhesive polymers. This review summarizes different pharmaceutical approaches which overcome various physiological barriers that help to improve oral bioavailability that ultimately achieve formulation goals for oral delivery.

Abstract
We have designed a novel colonoscopic imaging agent that is composed of submicron-sized fluorescent polystyrene nanospheres with two functional groups - peanut agglutinin (PNA) and poly(N-vinylaceamide) (PNVA) - on their surfaces. PNA is a targeting moiety that binds to β-d-galactosyl-(1-3)-N-acetyl-d-galactosamine (Gal-β(1-3)GalNAc), which is the terminal sugar of the Thomsen-Friedenreich antigen that is specifically expressed on the mucosal side of colorectal cancer cells; it is anchored on the nanosphere surface via a poly(methacrylic) acid (PMAA) linker. PNVA is immobilized to enhance the specificity of PNA by reducing nonspecific interactions between the imaging agent and normal tissues. The essential nature of both functional groups was evaluated through in vivo experiments using PNA-free and PNVA-free nanospheres. The imaging agent recognized specifically tumors on the cecal mucosa of immune-deficient mice in which human colorectal cancer cells had been implanted; however, the recognition capability disappeared when PNA was replaced with wheat germ agglutinin, which has no affinity for Gal-β(1-3)GalNAc. PNA-free nanospheres with exclusively surface PNVA chains rarely adhered to the cecal mucosa of normal mice that did not undergo the cancer cell implantation. In contrast, there were strong nonspecific interactions between normal tissues and PNA-free nanospheres with exclusively surface PMAA chains. In vivo data proved that PNA and PNVA were essential for biorecognition for tumor tissues and a reduction of nonspecific interactions with normal tissues, respectively.

Abstract
It was the aim of the present study to evaluate and compare the distribution of thiolated mucoadhesive anionic poly(acrylic acid) (PAA) and cationic chitosan (CS) nanoparticles on intestinal mucosa. Modifications of these polymers were achieved by conjugation with cysteine (PAA-Cys) and 2-iminothiolane (CS-TBA). Nanoparticles (NP) were prepared by ionic gelation and labelled with the strong hydrophilic fluorescent dye Alexa Fluor 488 (AF 488) and hydrophobic fluorescein diacetate (FDA). Unmodified and modified CS and PAA NP were examined in vitro in terms of their mucoadhesive and mucus penetrating properties on the mucosa of rat small intestine. To investigate the transport of NP across the mucus layer, their diffusion behaviour through natural porcine intestinal mucus was studied through a new diffusion method developed by our group. Lyophilised particles displayed 526 μmol/g (CS) and 513 μmol/g (PAA) of free thiol groups and a zeta potential of 20 mV (CS) and -14 mV for PAA NP. Nanoparticle distribution on rat intestine suggested that mucoadhesion of thiolated NP is higher than the diffusion into the intestinal mucosa. Modified particles displayed more than a 6-fold increase in mucoadhesion compared to unmodified ones. The rank order with regard to mucoadhesion of all particles was: CS-TBA>PAA-Cys>CS>PAA, whereas CS-TBA showed 2-fold higher mucoadhesive properties compared to PAA-Cys NP. Diffusion through intestinal mucus was much higher for unmodified than for thiolated as well as for anionic compared to cationic particles. Overall, it was shown that thiolated particles of both anionic and cationic polymers have improved mucoadhesive properties and could be promising carriers for mucosal drug delivery.

Abstract
We designed peanut agglutinin (PNA)-immobilized fluorescent nanospheres as a non-absorbable endoscopic imaging agent capable of being administered intracolonically. Following our previous researches with evidence that the imaging agent recognized small-sized colorectal tumors on the mucosal surface with high affinity and specificity in animal experiments, a potential of this nanoprobe as a drug candidate was evaluated from a safety perspective. The imaging agent detects colorectal tumors through recognition of the tumor-specific antigen by PNA immobilized on the nanosphere surface, and the detection is made via the fluorescent signal derived from coumarin 6 encapsulated into the nanosphere core. The stability studies revealed that the high activity of PNA was maintained and there was no significant leakage of coumarin 6 after intracolonic administration of the imaging agent. Cytotoxicity studies indicated that no local damage to the large intestinal membrane was induced by the imaging agent. Further, in vitro and in vivo permeation studies demonstrated that there was no significant permeation of the imaging agent through the monolayer of cultured cells and that the imaging agent administered locally to the luminal side of the large intestine was almost completely recovered from the administration site. Therefore, we concluded that the imaging agent is a safe and stable probe which remains in the large intestine without systemic exposure.

Abstract
The aims of this study were to prepare fine pidotimod-containing water-in-oil-in-water (W/O/W) double emulsions and to investigate the possibility of those emulsions as a delivery system for promoting the oral bioavailability of pidotimod. A modified two-step emulsification procedure was applied to prepare the double emulsions using medium-chain triglyceride as the oil phase, Tween 80 as the hydrophilic emulsifier, and Span 80 alone or in combination with different amount of phospholipids as the lipophilic emulsifiers. A fine W/O/W emulsion, with the encapsulation efficiency of 82 ± 3.4%, mean oil-droplet diameter of 3.93 ± 0.25 μm, and viscosity of 36.4 ± 0.93 mPa · s at 25 °C and 300 s(-1), was stable for 1 month at 4 °C. In addition, the oral bioavailability of pidotimod in rats, after intragastric administration of W/O/W double emulsions, was significantly higher than that of pidotimod control solution. Moreover, the maximum uptake time was significantly prolonged, suggesting an extra absorption pathway for W/O/W emulsions: a lymphatic circulation pathway. Those results demonstrated that W/O/W emulsions could become a potential formulation for improving the oral bioavailability of poorly absorbable drugs and suggested an important technology platform for the oral administration of peptide and peptidomimetic drugs.

Abstract
The present study was designed to explore the ability of polymeric nanoparticles to restore drug sensitivity to P-glycoprotein over-expressing cancer cells. A multidrug-resistant cell line 2780 AD and its sensitive parent cell line A2780 were studied in cell culture and as a xenografted tumour model. Paclitaxel was incorporated in poly(lactide-co-glycolide) nanoparticles of average diameter 125 nm stabilised by a positively charged surfactant. The nanoparticulate formulation was shown to be about sevenfold more potent than free paclitaxel against cell line A2780 and the poly(lactic-co-glycolic acid) (PLGA) nanoparticles alone were nontoxic to the cells at the concentrations required to deliver the drug. Whilst the oral formulation of paclitaxel was not as potent as the free drug in the A2780 xenografts, it showed significant activity against 2780 AD tumours, which are resistant to the maximum tolerated intravenous dose of paclitaxel. The efficacy of orally delivered paclitaxel in this drug-resistant model supports the concept of exploring nanoparticles for improved drug delivery.

Abstract
Stability enhancement of protein-loaded chitosan microparticles under storage was investigated. Chitosan glutamate at 35 kDa and bovine serum albumin as model protein drug were used in this study. The chitosan microparticles were prepared by ionotropic gelation, and polyethylene glycol 200 (PEG 200) was applied after the formation of the particles. All chitosan microparticles were kept at 25°C for 28 days. A comparison was made between those preparations with PEG 200 and without PEG 200. The changes in the physicochemical properties of the microparticles such as size, zeta potential, pH, and percent loading capacity were investigated after 0, 3, 7, 14, and 28 days of storage. It was found that the stability decreased upon storage and the aggregation of microparticles could be observed for both preparations. The reduction in the zeta potential and the increase in the pH, size, and loading capacity were observed when they were kept at a longer period. The significant change of those preparations without PEG 200 was evident after 7 days of storage whereas those with PEG 200 underwent smaller changes with enhanced stability after 28 days of storage. Therefore, this investigation gave valuable information on the stability enhancement of the microparticles. Hence, enhanced stability of chitosan glutamate microparticles for the delivery of protein could be achieved by the application of PEG 200.

Abstract
To enhance oral absorption of poorly water-soluble daidzein, self-microemulsifying drug delivery system (SMEDDS) composed of oil, surfactant and cosurfactant for oral administration of daidzein was formulated, and its physicochemical properties and pharmacokinetic parameters were evaluated. Solubility of daidzein was determined in various vehicles. Pseudo-ternary phase diagrams were constructed to identify the efficient self-microemulsification region and particle size distributions of the resultant microemulsions were determined using a laser diffraction sizer. From these studies, an optimized formulation consisting of Ethyl oleate (10%), Cremophor RH 40 (60%), and polyethylene glycol 400 (PEG400) (30%) was selected. The dissolution rate of daidzein from SMEDDS was significantly higher than the conventional tablet. Relative bioavailability of SMEDDS was enhanced about 2.5-fold compared with that of the control group. The data suggest that the use of SMEDDS provide a potential way of daidzein administered orally.

J Control Release 2010; 148:187-96. [PMID: 20800631 DOI: 10.1016/j.jconrel.2010.08.022] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2010] [Revised: 07/27/2010] [Accepted: 08/16/2010] [Indexed: 11/18/2022]
Abstract
Oligoarginines, which are known as cell-penetrating peptides, enhance the cellular uptake of poorly membrane-permeable bioactive molecules that are chemically conjugated to them. We designed a novel polymer: oligoarginine-linked poly(N-vinylacetamide-co-acrylic acid), with the expectation that the polymers will enhance the cellular uptake of the bioactive molecules that are physically mixed with them. Oligoarginines were grafted onto the polymer backbone through the chemical reaction with acrylic acid functional groups. The changes in the blood glucose concentration after nasal administration of insulin with and without the polymer were monitored in mice. The blood glucose concentration was slightly reduced when insulin was given solely at a dose of 10IU/kg. A D-octaarginine-linked poly(N-vinylacetamide-co-acrylic acid) with a grafting degree of 2% significantly enhanced the insulin-induced hypoglycemic effect. A similar enhancement was not observed when the polymer was substituted with intact D-octaarginine. The penetration-enhancing function of D-octaarginine-linked poly(N-vinylacetamide-co-acrylic acid) increased dramatically with an increase in the grafting degree of D-octaarginine. Substitution of D-octaarginine with the corresponding optical isomer and an increase in the number of arginine residues rather reduced the penetration-enhancing function. In vitro cell studies also indicated that a D-octaarginine-linked poly(N-vinylacetamide-co-acrylic acid) with a grafting degree of 17% enabled fluorescein isothiocyanate-dextran to effectively penetrate the cell membrane. Results demonstrated that our oligoarginine-linked polymer has a potential to provide a new class of penetration enhancers.

Abstract
A series of novel, pH-sensitive, endosomolytic polymers based on imidazole-grafted polyaspartamide were synthesized to characterize the pH-sensitive membrane fusion properties of red blood cells and their toxicity to L929 cells. All imidazole-containing polymers exhibited strong cationic characteristics under acidic conditions, as well as a high buffering effect in the pH range 5-7. In the presence of O-(2-aminoethyl)-O'-methylpolyethylene glycol and 1-(3-aminopropyl)imidazole-grafted polyaspartamide (MPEG/API-g-PASPAM) systems red blood cells agglutinated below pH 6.5 without any hemolytic effect. The octadecylamine, O-(2-aminoethyl)-O'-methylpolyethylene glycol and 1-(3-aminopropyl)imidazole-grafted polyaspartamide (C18/MPEG/API-g-PASPAM) systems, however, displayed considerable hemolytic behavior below pH 6.5, but no hemolysis occurred above this pH. It can be concluded from these results that not only the pH-sensitive imidazole group, but also the hydrophobic octadecyl chain plays a critical role in membrane fusion. The hypothetical mechanism of this fusion involves both ionic and hydrophobic interactions between the polymers and lipid bilayers.
