Abstract
Targeted delivery of drug molecules to diseased sites is a great challenge in pharmaceutical and biomedical sciences. Fabrication of drug delivery systems (DDS) to target and/or diagnose sick cells is an effective means to achieve good therapeutic results along with a minimal toxicological impact on healthy cells. Biopolymers are becoming an important class of materials owing to their biodegradability, good compatibility, non-toxicity, non-immunogenicity, and long blood circulation time and high drug loading ratio for both macros as well as micro-sized drug molecules. This review summarizes the recent trends in biopolymer-based DDS, forecasting their broad future clinical applications. Cellulose chitosan, starch, silk fibroins, collagen, albumin, gelatin, alginate, agar, proteins and peptides have shown potential applications in DDS. A range of synthetic techniques have been reported to design the DDS and are discussed in the current study which is being successfully employed in ocular, dental, transdermal and intranasal delivery systems. Different formulations of DDS are also overviewed in this review article along with synthesis techniques employed for designing the DDS. The possibility of these biopolymer applications points to a new route for creating unique DDS with enhanced therapeutic qualities for scaling up creative formulations up to the clinical level.

Abstract
Tamoxifen (TMX) is used to treat hormone-receptor-positive breast cancers at early stages. This research aimed to assess the potential of NPs in targeted delivery of TMX against MCF7 and TMX-resistant MCF7 breast cancer cell lines. For this purpose, a targeted delivery system including chitosan NPs coated with hyaluronic acid (HA-CS NPs) was created and examined in vitro. Chitosan NPs were first fabricated and loaded with TMX using the ionic-gelation method to prepare a drug-delivery system. Then, TMX-loaded CS NPs were coated by crosslinking the amino groups of chitosan to the carboxylic group of hyaluronic acid. The developed TMX delivery system was then optimized and characterized for particle fabrication, drug release, and targeting against cancer cells. The HA-CS particle size was 210 nm and its zeta potential was +25 mv. The encapsulation efficiency of TMX in NPs was 55%. TMX released from the NPs in acidic pH (5-6) was higher than the physiological pH (7.4). The cytotoxic effect of TMX-loaded HA-CS NPs on MCF7 and TMX-resistant MCF7 cells was significantly higher than TMX-loaded CS NPs and free drug. The findings confirmed the significant suppressive impact of TMX-loaded HA-CS NPs on MCF7 and TMX-resistant MCF7 cancer cells compared to the TMX-loaded CS NPs and free TMX. Graphical abstract.

Abstract
Endoxifen is the primary active metabolite of tamoxifen, a nonsteroidal-selective estrogen receptor modulator (SERM) and widely used medication to treat estrogen receptor-positive (ER+) breast cancer. In this study, endoxifen was conjugated to the surface of polymeric nanoparticles (polymersomes) for targeted delivery of doxorubicin (DOX) to estrogen receptor-positive breast cancer cells (MCF7). Rapid cell growth and insufficient blood supply result in low oxygen concentration (hypoxia) within the solid breast tumors. The polymersomes developed here are prepared from amphiphilic copolymers of polylactic acid (PLA) and poly(ethylene glycol) (PEG) containing diazobenzene as the hypoxia-responsive linker. We prepared two nanoparticle formulations: DOX-encapsulated hypoxia-responsive polymersomes (DOX-HRPs) and endoxifen-conjugated, DOX-encapsulated hypoxia-responsive polymersomes (END-DOX-HRPs). Cellular internalization studies demonstrated eight times higher cytosolic and nuclear localization after incubating breast cancer cells with END-DOX-HRPs (targeted polymersomes) in contrast to DOX-HRPs (nontargeted polymersomes). Cytotoxicity studies on monolayer cell cultures exhibited that END-DOX-HRPs were three times more toxic to ER+ MCF7 cells than DOX-HRPs and free DOX in hypoxia. The cell viability studies on three-dimensional hypoxic cultures also demonstrated twice as much toxicity when the spheroids were treated with targeted polymersomes instead of nontargeted counterparts. This is the first report of surface-decorated polymeric nanoparticles with endoxifen ligands for targeted drug delivery to ER+ breast cancer microtumors. The newly designed endoxifen-conjugated, hypoxia-responsive polymersomes might have translational potential for ER+ breast cancer treatment.

Abstract
Chitosan, derived from chitin, is a biopolymer consisting of arbitrarily distributed β-(1-4)-linked D-glucosamine and N-acetyl-D-glucosamine that exhibits outstanding properties- biocompatibility, biodegradability, non-toxicity, antibacterial activity, the capacity to form films, and chelating of metal ions. Most of these peculiar properties are attributed to the presence of free protonable amino groups along the chitosan backbone, which also gives it solubility in acidic conditions. Moreover, this biopolymer can also be physically modified, thereby presenting a variety of forms to be developed. Consequently, this polysaccharide is used in various fields, such as tissue engineering, drug delivery systems, and cancer treatment. In this sense, this review aims to gather the state-of-the-art concerning this polysaccharide when used as a biomaterial, providing information about its characteristics, chemical modifications, and applications. We present the most relevant and new information about this polysaccharide-based biomaterial's applications in distinct fields and also the ability of chitosan and its various derivatives to selectively permeate through the cancer cell membranes and exhibit anticancer activity, and the possibility of adding several therapeutic metal ions as a strategy to improve the therapeutic potential of this polymer.

Abstract
As the most abundant protein with a variety of physiological functions, albumin has been used extensively for the delivery of therapeutic molecules. Thiolactone chemistry provides a powerful tool to prepare spin-labeled albumin-based multimodal imaging probes and therapeutic agents. We report the synthesis of a tamoxifen homocysteine thiolactone derivative and its use in thiol-'click' chemistry to prepare multi-functionalized serum albumin. The released sulfhydryl group of the homocysteine functional handle was labeled with a nitroxide reagent to prepare a spin-labeled albumin-tamoxifen conjugate confirmed by MALDI-TOF-MS, EPR spectroscopy, UV-vis and fluorescent emission spectra. This is the basis for a novel multimodal tamoxifen-albumin theranostic with a significant (dose-dependent) inhibitory effect on the proliferation of malignant cells. The response of human glioblastoma multiforme T98G cells and breast cancer MCF-7 cells to tamoxifen and its albumin conjugates was different in tumor cells with different expression level of ERα in our experiments. These results provide further impetus to develop a serum protein for delivery of tamoxifen to cancer cells.

Abstract
We examine the interactions of chitosan and polyethylene glycol (PEG) with antimicrobial peptide GF-17 to identify a suitable carrier to improve the peptide drug delivery systems. To this end, the molecular dynamics simulations are used to determine the interactions of a typical antimicrobial peptide GF-17 with the chitosan and PEG polymers. The findings indicate the great potential of the peptide to maintain its secondary structure in the adjacent to chitosan polymers. During the interaction with chitosan polymers, the structure of the peptide has smaller fluctuations compared to the PEG polymers. Also, in the presence of both the polymers, the PEG polymers are situated closer to the peptide than chitosan polymers. Moreover, the analysis indicates that the acidic residues and phenylalanine play a crucial role in peptide-polymer interactions. This research provides a valuable insight into the design of polymer surfaces for drug delivery applications such as controlled-release peptide delivery systems.

Abstract
Breast cancer (BC) is one of the leading causes of death from cancer in women; second only to lung cancer. Tamoxifen (TAM) is a hydrophobic anticancer agent and a selective estrogen modulator (SERM), approved by the FDA for hormone therapy of BC. Despite having striking efficacy in BC therapy, concerns regarding the dose-dependent carcinogenicity of TAM still persist, restricting its therapeutic applications. Nanotechnology has emerged as one of the most important strategies to solve the issue of TAM toxicity, owing to the ability of nano-enabled-formulations to deliver smaller concentrations of TAM to cancer cells, over a longer period of time. Various TAM-containing-nanosystems have been successfully fabricated to selectively deliver TAM to specific molecular targets found on tumour membranes, reducing unwanted toxic effects. This review begins with an outline of breast cancer, the current treatment options and a history of how TAM has been used as a combatant of BC. A detailed discussion of various nanoformulation strategies used to deliver lower doses of TAM selectively to breast tumours will then follow. Finally, a commentary on future perspectives of TAM being employed as a targeting vector, to guide the delivery of other therapeutic and diagnostic agents selectively to breast tumours will be presented.

Abstract
The binding efficacy of anticancer drugs doxorubicin and tamoxifen with polyamidoamine (PAMAM-G4) dendrimers was studied in aqueous solution at physiological pH. The results of multiple spectroscopic methods, transmission electron microscopy (TEM), and molecular modeling of conjugated drug–polymer were examined. Structural analysis showed that drug–polymer conjugation occurs mainly via H-bonding and hydrophilic and hydrophobic contacts. Doxorubicin forms a more stable conjugate with PAMAM-G4 than tamoxifen. The drug loading efficacy was 40%–50%. The TEM images showed major changes in the PAMAM morphology upon drug encapsulation. Modeling showed that drug is located in the polymer surface and in the internal cavities. PAMAM nanoparticles are capable of transporting doxorubicin and tamoxifen in vitro. This minireview presents the most recent work performed with the dendrimers demonstrating their usefulness for drug delivery in cancer therapy.

Abstract
Conjugation of antitumor drug tamoxifen and its metabolites, 4-hydroxytamxifen and ednoxifen with synthetic polymers poly(ethylene glycol) (PEG), methoxypoly (ethylene glycol) polyamidoamine (mPEG-PAMAM-G3) and polyamidoamine (PAMAM-G4) dendrimers was studied in aqueous solution at pH 7.4. Multiple spectroscopic methods, transmission electron microscopy (TEM) and molecular modeling were used to characterize the drug binding process to synthetic polymers. Structural analysis showed that drug-polymer binding occurs via both H-bonding and hydrophobic contacts. The order of binding is PAMAM-G4>mPEG-PAMAM-G3>PEG-6000 with 4-hydroxttamoxifen forming more stable conjugate than tamoxifen and endoxifen. Transmission electron microscopy showed significant changes in carrier morphology with major changes in the shape of the polymer aggregate as drug encapsulation occurred. Modeling also showed that drug is located in the surface and in the internal cavities of PAMAM with the free binding energy of -3.79 for tamoxifen, -3.70 for 4-hydroxytamoxifen and -3.69kcal/mol for endoxifen, indicating of spontaneous drug-polymer interaction at room temperature.

Abstract
Background Tamoxifen is currently used for the treatment of both early and advanced estrogen receptor (ER) positive breast cancer in pre- and post-menopausal women. However, using tamoxifen routinely to inhibit endogenous or exogenous estrogen effects is occasionally difficult because of its potential side effects. Objectives The aim of this study is to design a local drug delivery system to encapsulate tamoxifen for observing their efficacy of skin penetration, drug accumulation and cancer therapy. Methods A cationic liposome-PEG-PEI complex (LPPC) was used as a carrier for the encapsulation of tamoxifen and forming ‘LPPC/TAM’ for transdermal release. The cytotoxicity of LPPC/TAM was analyzed by MTT. The skin penetration, tumor growth inhibition and organ damages were measured in xenograft mice following transdermal treatment. Results LPPC/TAM had an average size less than 270 nm and a zeta-potential of approximately 40 mV. LPPC/TAM displayed dramatically increased the cytotoxic activity in all breast cancer cells, especially in ER-positive breast cancer cells. In vivo, LPPC drug delivery helped the fluorescent dye penetrating across the skim and accumulating rapidly in tumor area.
Administration of LPPC/TAM by transdermal route inhibited about 86 % of tumor growth in mice bearing BT474 tumors. This local treatment of LPPC/TAM did not injury skin and any organs. Conclusion LPPC-delivery system provided a better skin penetration and drug accumulation and therapeutic efficacy. Therefore, LPPC/TAM drug delivery maybe a useful transdermal tool of drugs utilization for breast cancer therapy.

Abstract
The conjugation of tRNA with chitosan nanoparticles of different sizes 15,100 and 200 kDa was investigated in aqueous solution using multiple spectroscopic methods and atomic force microscopy (AFM). Structural analysis showed that chitosan binds tRNA via G-C and A-U base pairs as well as backbone PO2 group, through electrostatic, hydrophilic and H-bonding contacts with overall binding constants of KCh-15-tRNA=4.1 (±0.60)×10(3)M(-1), KCh-100-tRNA=5.7 (±0.8)×10(3)M(-1) and KCh-200-tRNA=1.2 (±0.3)×10(4)M(-1). As chitosan size increases more stable polymer-tRNA conjugate is formed. AFM images showed major tRNA aggregation and particle formation occurred as chitosan concentration increased. Even though chitosan induced major biopolymer structural changes, tRNA remains in A-family structure.

Abstract
Conjugations of DNA with chitosans 15 kD (ch-15), 100 kD (ch-100) and 200 kD (ch-200) were investigated in aqueous solution at pH 5.5-6.5. Multiple spectroscopic methods and atomic force microscopy (AFM) were used to locate the chitosan binding sites and the effect of polymer conjugation on DNA compaction and particle formation. Structural analysis showed that chitosan-DNA conjugation is mainly via electrostatic interactions through polymer cationic charged NH2 and negatively charged backbone phosphate groups. As polymer size increases major DNA compaction and particle formation occurs. At high chitosan concentration major DNA structural changes observed indicating a partial B to A-DNA conformational transition.

Abstract
![]()
Breast cancer is the second leading
cause of cancer-related death
in women. The majority of breast tumors are estrogen receptor-positive
(ER+) and hormone-dependent. Neoadjuvant anti-estrogen therapy has
been widely employed to reduce tumor mass prior to surgery. Tamoxifen
is a broadly used anti-estrogen for early and advanced ER+ breast
cancers in women and the most common hormone treatment for male breast
cancer. 4-Hydroxytamoxifen (4-OHT) is an active metabolite of tamoxifen
that functions as an estrogen receptor antagonist and displays higher
affinity for estrogen receptors than that of tamoxifen and its other
metabolites. MicroRNA-21 (miR-21) is a small noncoding RNA of 23 nucleotides
that regulates several apoptotic and tumor suppressor genes and contributes
to chemoresistance in numerous cancers, including breast cancer. The
present study investigated the therapeutic potential of 4-OHT and
anti-miR-21 coadministration in an attempt to combat tamoxifen resistance,
a common problem often encountered in anti-estrogen therapy. A biodegradable
poly(d,l-lactide-co-glycolide)-block-poly(ethylene glycol) (PLGA-b-PEG-COOH)
copolymer was utilized as a carrier to codeliver 4-OHT and anti-miR-21
to ER+ breast cancer cells. 4-OHT and anti-miR-21 co-loaded PLGA-b-PEG nanoparticles (NPs) were developed using emulsion-diffusion
evaporation (EDE) and water-in-oil-in-water (w/o/w) double emulsion
methods. The EDE method was found to be best method for 4-OHT loading,
and the w/o/w method proved to be more effective for coloading NPs
with anti-miR-21 and 4-OHT. The optimal NPs, which were prepared using
the double emulsion method, were evaluated for their antiproliferative
and apoptotic effects against MCF7, ZR-75-1, and BT-474 human breast
cancer cells as well as against 4T1 mouse mammary carcinoma cells.
We demonstrated that PLGA-b-PEG NP encapsulation
significantly extended 4-OHT’s stability and biological activity
compared to that of free 4-OHT. MTT assays indicated that treatment
of MCF7 cells with 4-OHT–anti-miR-21 co-loaded NPs resulted
in dose-dependent antiproliferative effects at 24 h, which was significantly
higher than what was achieved with free 4-OHT at 48 and 72 h post-treatment.
Cell proliferation analysis showed that 4-OHT and anti-miR-21 co-loaded
NPs significantly inhibited MCF-7 cell growth compared to that of
free 4-OHT (1.9-fold) and untreated cells (5.4-fold) at 1 μM
concentration. The growth rate of MCF7 cells treated with control
NPs or NPs loaded with anti-miR-21 showed no significant difference
from that of untreated cells. These findings demonstrate the utility
of the PLGA-b-PEG polymer NPs as an effective nanocarrier
for co-delivery of anti-miR-21 and 4-OHT as well as the potential
of this drug combination for use in the treatment of ER+ breast cancer.

Abstract
The binding sites of breast anticancer drug tamoxifen and its metabolites with tRNA were located by FTIR, CD, UV-visible, and fluorescence spectroscopic methods and molecular modeling. Structural analysis showed that tamoxifen and its metabolites bind tRNA at several binding sites with overall binding constants of K(tam-tRNA) = 5.2 (± 0.6) × 10(4) M(-1), K(4-hydroxytam-tRNA) = 6.5 ( ± 0.5) × 10(4) M(-1) and K(endox-tRNA) = 1.3 (± 0.2) × 10(4) M(-1). The number of binding sites occupied by drug molecules on tRNA were 1 (tamoxifen), 0.8 (4-hydroxitamoxifen) and 1.2 (endoxifen). Docking showed the participation of several nucleobases in drug-tRNA complexes with the free binding energy of -4.31 (tamoxifen), -4.45 (4-hydroxtamoxifen) and -4.38 kcal/mol (endoxifen). The order of binding is 4-hydroxy-tamoxifen > tamoxifen > endoxifen. Drug binding did not alter tRNA conformation from A-family structure, while biopolymer aggregation occurred at high drug concentration.

Abstract
We have reviewed the binding affinities of several antitumor drugs doxorubicin (Dox), N-(trifluoroacetyl) doxorubicin (FDox), tamoxifen (Tam), 4-hydroxytamoxifen (4-Hydroxytam), and endoxifen (Endox) with chitosan nanoparticles of different sizes (chitosan-15, chitosan-100, and chitosan-200 KD) in order to evaluate the efficacy of chitosan nanocarriers in drug delivery systems. Spectroscopic and molecular modeling studies showed the binding sites and the stability of drug-polymer complexes. Drug-chitosan complexation occurred via hydrophobic and hydrophilic contacts as well as H-bonding network. Chitosan-100 KD was the more effective drug carrier than the chitosan-15 and chitosan-200 KD.

Abstract
BACKGROUND AND AIMS To investigate the synergistic effect of IL-1Ra administration and stem cell transplantation in swine suffering from acute liver failure (ALF), to elucidate the mechanism of IL-1Ra activity and to demonstrate mesenchymal stem cell (MSC) transplantation as a potential treatment for ALF. METHODS Thirty-five Chinese experimental mini-swine were divided into five groups randomly. Group A (n = 7) is the control group and all swine were injected with saline via portal veins. Group B (n = 7) received IL-1Ra via ear veins 6 h before receiving saline. Group C (n = 7) received MSC transplantation and all swine were injected with 8 × 10⁷ MSCs via portal veins. Group D (n = 7) swine were treated with a combination of IL-1Ra and MSC transplantation E (n = 7) also received a combined treatment of both IL-1Ra and bone marrow (BM-MSC) transplantation, except that the IL-1Ra was in the form of chitosan nanoparticles. Liver function, level of cytokines and liver pathological changes were measured in the following 4 weeks. RESULTS IL-1Ra chitosan nanoparticles exhibited controlled-release ability in PBS. Swine in Group E showed a significant improvement in inflammation environment, liver function and hepatocyte proliferation. Levels of hepatocyte growth factor (HGF) and vascular endothelial growth factor (VEGF) in Group E were elevated compared to other groups. CONCLUSIONS IL-1Ra chitosan nanoparticles showed significant liver targeting ability and controlled-release characteristics. Combined therapy with IL-1Ra chitosan nanoparticles and MCS transplantation exhibits great synergistic effects through paracrine function and suppression of inflammation.
