Abstract
Nanomedicines are considered next generation therapeutics with advanced therapeutic properties and reduced side effects. Herein, we introduce tailored linear and star-like water-soluble nanosystems as stimuli-sensitive nanomedicines for the treatment of solid tumors or hematological malignancies. The polymer carrier and drug pharmacokinetics were independently evaluated to elucidate the relationship between the nanosystem structure and its distribution in the body. Positron emission tomography and optical imaging demonstrated enhanced tumor accumulation of the polymer carriers in 4T1-bearing mice with increased tumor-to-blood and tumor-to-muscle ratios. Additionally, there was a significant accumulation of doxorubicin bound to various polymer carriers in EL4 tumors, as well as excellent in vivo therapeutic activity in EL4 lymphoma and moderate efficacy in 4T1 breast carcinoma. The linear nanomedicine showed at least comparable pharmacologic properties to the star-like nanomedicines regarding doxorubicin transport. Therefore, if multiple parameters are considered such as its optimized structure and simple and reproducible synthesis, this polymer carrier system is the most promising for further preclinical and clinical investigations.

Abstract
Background:Glutathione (GSH), which is the predominant low molecular weight intracellular thiol in mammals, has multiple functions, such as those of protecting against oxidative stress and detoxifying endogenous and exogenous electrophiles. High GSH levels, which have been observed in various types of tumors, have been thought to contribute to the resistance of neoplastic cells to apoptotic stimuli triggered by pro-oxidant therapy. Although L-(S,R)-Buthionine Sulfoximine (BSO), a selective irreversible inhibitor of glutamate cysteine ligase, depletes GSH in vitro and in in vivo and sensitizes tumor cells to radiation and some cancer chemotherapeutics, its toxicity and short in vivo half-life have limited its application to combination anticancer therapies.Objective:To demonstrate that a folate-targeted PEGylated BSO conjugate can sensitize cancer cells to a Reactive Oxygen Species (ROS)-generating anticancer agent by depleting GSH.Methods:A novel folate-targeted PEGylated-BSO conjugate was synthesized and tested in combination with gemcitabine in human cell lines that over-express (HeLa) or do not express (A549) the folate receptor.Results:The prepared folate-PEG-GFLG-BSO conjugate proved to be efficacious in reducing GSH levels and, when used in combination with the pro-oxidant drug gemcitabine, it enhanced drug activity in the cell line overexpressing the folate receptor.Conclusion:The folate-PEG-GFLG-BSO conjugate studied was found to be effective in sensitizing folatereceptor positive cancer cells to the ROS-generating drug gemcitabine.

Abstract
Chemotherapy drug (paclitaxel, PTX) incorporated in a dual functional polymeric nanocarrier, PEG-Fmoc-NLG, has shown promise as an immunochemotherapy in a murine breast cancer model, 4T1.2. The formulation is composed of an amphiphilic polymer with a built-in immunotherapy drug NLG919 that exhibits the immunostimulatory ability through the inhibition of indoleamine 2,3-dioxygenase 1 (IDO-1) in cancer cells. This work evaluates whether the PEG-derivatized NLG polymer can also be used for delivery of doxorubicin (Dox) in treatment of leukemia. The Dox-loaded micelles were self-assembled from PEG-Fmoc-NLG conjugate, which have a spherical shape with a uniform size of ∼120 nm. In cultured murine lymphocytic leukemia cells (A20), Dox-loaded PEG-Fmoc-NLG micelles showed a cytotoxicity that was comparable to that of free Dox. For in vivo studies, significantly improved antitumor activity was observed for the Dox/PEG-Fmoc-NLG group compared to Doxil or the free Dox group in an A20 lymphoma mouse model. Flow cytometric analysis showed that treatment with Dox/PEG-Fmoc-NLG micelles led to significant increases in the numbers of both total CD4+/CD8+ T cells and the functional CD4+/CD8+ T cells with concomitant decreases in the numbers of myeloid-derived suppressor cells (MDSCs) and regulatory T cells (Treg). Dox/PEG-Fmoc-NLG may represent a promising immunochemotherapy for lymphoma, which warrants more studies in the future.

Abstract
Over the past few decades, numerous polymer drug carrier systems are designed and synthesized, and their properties are evaluated. Many of these systems are based on water-soluble polymer carriers of low-molecular-weight drugs and compounds, e.g., cytostatic agents, anti-inflammatory drugs, or multidrug resistance inhibitors, all covalently bound to a carrier by a biodegradable spacer that enables controlled release of the active molecule to achieve the desired pharmacological effect. Among others, the synthetic polymer carriers based on N-(2-hydroxypropyl) methacrylamide (HPMA) copolymers are some of the most promising carriers for this purpose. This review focuses on advances in the development of HPMA copolymer carriers and their conjugates with anticancer drugs, with triggered drug activation in tumor tissue and especially in tumor cells. Specifically, this review highlights the improvements in polymer drug carrier design with respect to the structure of a spacer to influence controlled drug release and activation, and its impact on the drug pharmacokinetics, enhanced tumor uptake, cellular trafficking, and in vivo antitumor activity.

Abstract
Polymer carriers based on N-(2-hydroxypropyl)methacrylamide (HPMA) copolymers with incorporated organic nitrates as nitric oxide (NO) donors were designed with the aim to localise NO generation in solid tumours, thus highly increasing the enhanced permeability and retention (EPR) effect. The NO donors were coupled to the polymer carrier either through a stable bond or through a hydrolytically degradable, pH sensitive, bond. In vivo, the co-administration of the polymer NO donor and HPMA copolymer-bound cytotoxic drug (doxorubicin; Dox) resulted in an improvement in the treatment of murine EL4 T-cell lymphoma. The polymer NO donors neither potentiated the in vitro toxicity of the cytotoxic drug nor exerted any effect on in vivo model without the EPR effect, such as BCL1 leukaemia. Thus, an increase in passive accumulation of the nanomedicine carrying cytotoxic drug via NO-enhanced EPR effect was the operative mechanism of action. The most significant improvement in the therapy was observed in a combination treatment with such a polymer conjugate of Dox, which is characterised by increased circulation in the blood and efficient accumulation in solid tumours. Notably, the combination treatment enabled the development of an anti-tumour immune response, which was previously demonstrated as an important feature of HPMA-based polymer cytotoxic drugs.

Abstract
Two conjugates of anticancer drug doxorubicin (Dox) covalently bound by the hydrolytically degradable hydrazone bond to the polymer carrier based on water-soluble N-(2-hydroxypropyl) methacrylamide (HPMA) copolymers were synthesized and their properties were compared, namely their behavior in vivo. The polymer carriers differed in dispersity due to different methods of synthesis; the carrier with relatively high dispersity (HD) was prepared by free radical polymerization (Mw = 29 900 g/mol, Ð = 1.75) and the carrier with low dispersity (LD) by controlled radical polymerization (Mw = 30 000 g/mol, Ð = 1.13). Both polymer-Dox conjugates showed prolonged blood circulation and tumor accumulation of the drug in comparison with the free drug; e.g. the tumor-to-blood ratio for the polymer-bound Dox was 3-5 times higher. The LD polymer-Dox conjugate exhibited moderately higher tumor accumulation than the HD one at a dose of 1 x 15 mg Dox (eq.)/kg. Also, their anti-tumor activity did not differ when injected at this dose. However, the increase of the dose to 1 x 25 mg Dox (eq.)/kg resulted in the enhanced therapeutic activity of the conjugates, especially of the LD one with 100 % of long-term survivals. The dispersity of polymer drug carriers influenced the tumor accumulation rate, which affected the overall anti-cancer activity of polymer-drug conjugates.

Abstract
A tumor-targeted and pH-responsive drug release system based on superparamagnetic iron oxide nanoparticles (IONPs) coated by poly(ethylene glycol) (PEG) and dodecylamine (DDA)-modified polyitaconic acid (PIA) connecting with bortezomib (BTZ) (PIA-PEG-DDA-BTZ@IOs) has been constructed and characterized. The anticancer drug BTZ was first conjugated using dopamine as the linker via catechol borate ester bond, which is acid cleavable and used as an ideal pH-responsive drug release system. The IONPs were then coated by PIA-PEG-DDA-BTZ to form micelles with good biocompatibility. The conjugates were further designed to target liver cancer cells overexpressing vascular endothelial growth factor (VEGF) by the targeting molecule anti-vascular endothelial growth factor (anti-VEGF). The magnetic resonance imaging showed that the targeting capability of IONPs-anti-VEGF conjugates to Hep G2 cells was more significant than that of non-anti-VEGF IONPs. From the above, this kind of novel dual-functional targeting probe could provide a new idea for the diagnosis and treatment of cancer.

Abstract
The transdermal administration of chemotherapeutic agents is a persistent challenge for tumor treatments. A model anticancer agent, epirubicin (EPI), is attached to functionalized superparamagnetic iron-oxide nanoparticles (SPION). The covalent modification of the SPION results in EPI-SPION, a potential drug delivery vector that uses magnetism for the targeted transdermal chemotherapy of skin tumors. The spherical EPI-SPION composite exhibits excellent magnetic responsiveness with a saturation magnetization intensity of 77.8 emu g(-1) . They feature specific pH-sensitive drug release, targeting the acidic microenvironment typical in common tumor tissues or endosomes/lysosomes. Cellular uptake studies using human keratinocyte HaCaT cells and melanoma WM266 cells demonstrate that SPION have good biocompatibility. After conjugation with EPI, the nanoparticles can inhibit WM266 cell proliferation; its inhibitory effect on tumor proliferation is determined to be dose-dependent. In vitro transdermal studies demonstrate that the EPI-SPION composites can penetrate deep inside the skin driven by an external magnetic field. The magnetic-field-assisted SPION transdermal vector can circumvent the stratum corneum via follicular pathways. The study indicates the potential of a SPION-based vector for feasible transdermal therapy of skin cancer.

Abstract
An efficient drug delivery system has been fabricated through an electrostatic interaction between epirubicin and H3PW12O40-functionalized silica encapsulated maghemite nanoparticles. The obtained nanoparticles were characterized for morphology, size distribution, drug loading efficiency, drug content and drug release behavior. Our results indicate that the hybrid nanoparticles possess high adsorption capacity for epirubicin (20.6wt.%) and high drug loading efficiency (82.6%). The drug release is greater in acetate buffer (95.8%) as compared to phosphate buffered saline (47.5%). The pH-responsive release of the hybrid drug carrier and high drug loading efficiency are its advantages as a promising carrier.

Abstract
Preclinical in vivo characterization of new polymeric drug conjugate candidates is crucial for understanding the effects of certain chemical modifications on distribution and elimination of these carrier systems, which is the basis for rational drug design. In our study we synthesized dual fluorescent HPMA copolymers of different architectures and molecular weights, containing one fluorescent dye coupled via a stable hydrazide bond functioning as the carrier label and the other one modeling the drug bound to a carrier via a pH-sensitive hydrolytically cleavable hydrazone bond. Thus, it was possible to track the in vivo fate, namely distribution, elimination and tumor accumulation, of the polymer drug carrier and a cleavable model drug simultaneously and noninvasively in nude mice using multispectral optical imaging. We confirmed our in vivo results by more detailed ex vivo characterization (imaging and microscopy) of autopsied organs and tumors. There was no significant difference in relative biodistribution in the body between the 30 KDa linear and 200 KDa star-like polymer, but the star-like polymer circulated much longer. We observed a moderate accumulation of the polymeric carriers in the tumors. The accumulation of the pH-sensitive releasable model drug was even higher compared to the polymer accumulation. Additionally, we were able to follow the long-term in vivo fate and to prove a time-dependent tumor accumulation of HPMA copolymers over several days.

Abstract
N-(2-Hydroxypropyl)methacrylamide (HPMA) copolymer—drug conjugates bearing the antiinflammatory and anti-proliferative drug dexamethasone (DEX) and the anti-cancer drug doxorubicin (DOX) bound to either the polymer carrier separately or in combination, were synthesized. Both the in vitro and in vivo anti-cancer activity on mouse B-cell (38C13) and T-cell (EL4) lymphoma was studied. The conjugates were fairly stable in model buffers at pH 7.4, simulating blood pH, and the drug was released by chemical hydrolysis at pH values based on the endosomal and lysosomal environments in the target cells (pH 5—6). As a control, polymer conjugates containing only a single-drug (DOX or DEX) attached to the HPMA copolymer carrier were synthesized and tested. Contrary to the treatment with either single drug conjugate, where no significant long-term survival was observed, a synergistic effect of the two drugs was manifested in vivo. Treatment of mice bearing B-cell lymphoma 38C13 formulated as a mixture of both single drug-containing conjugates or a as a conjugate with both drugs in combination gave long-term survivors.

Abstract
To avoid the side effects of the anti-cancer drug doxorubicin (Dox), we conjugated this drug to a N-(2-hydroxypropyl)methacrylamide (HPMA) copolymer backbone. Dox was conjugated via an amide bond (Dox-HPMA(AM), PK1) or a hydrazone pH-sensitive bond (Dox-HPMA(HYD)). In contrast to Dox and Dox-HPMA(HYD), Dox-HPMA(AM) accumulates within the cell's intracellular membranes, including those of the Golgi complex and endoplasmic reticulum, both involved in protein glycosylation. Flow cytometry was used to determine lectin binding and cell death, immunoblot to characterize the presence of CD7, CD43, CD44, and CD45, and high-performance anion exchange chromatography with pulsed amperometric detector analysis for characterization of plasma membrane saccharide composition. Incubation of EL4 cells with Dox-HPMA(AM) conjugate, in contrast to Dox or Dox-HPMA(HYD), increased the amounts of membrane surface-associated glycoproteins, as well as saccharide moieties recognized by peanut agglutinin, Erythrina cristagalli, or galectin-1 lectins. Only Dox-HPMA(AM) increased expression of the highly glycosylated membrane glycoprotein CD43, while expression of others (CD7, CD44, and CD45) was unaffected. The binding sites for galectin-1 are present on CD43 molecule. Furthermore, we present that EL4 treated with Dox-HPMA(AM) possesses increased sensitivity to galectin-1-induced apoptosis. In this study, we demonstrate that Dox-HPMA(AM) treatment changes glycosylation of the EL4 T cell lymphoma surface and sensitizes the cells to galectin-1-induced apoptosis.

Abstract
The main limitation of contemporary anticancer chemotherapy remains to be the insufficient specificity of the drugs for tumor tissue, which decreases the maximum tolerated dose due to severe side effects. Micellar drug delivery systems based on amphiphilic block copolymers with a very narrow size distribution (10 to 100 nm in diameter) is a novel innovative approach. Here, we report biological and pharmacological properties of polymeric micellar conjugate containing doxorubicin (DOX) covalently bound via hydrolytically cleavable hydrazone bonds to the micelle core. The system had a very low systemic toxicity (almost 20 times lower than free DOX) and long circulation in the bloodstream (with half of the dose after 24 h). Significant accumulation of tested micelles within the tumor was confirmed by fluorescent whole body imaging. Our new micellar system showed promising therapeutic activity against established murine EL-4 T-cell lymphoma; it was found that it is able to completely cure about 75% of tumor-bearing mice (with doses of either 1 x 150 mg DOX kg(-1) or 2 x 75 mg DOX kg(-1), administered i.v.). Moreover, treatment with micelles in cured mice induced tumor-specific resistance. Up to 80% of these mice survived rechallenge with original but not with distinct tumor cells.

Abstract
This paper reviews an early clinical experience with anthracycline (epirubicin; Epi or doxorubicin; Dox) containing an N-(2-hydroyxypropyl)methacrylamide copolymer carrier targeted with autologous or commercial human immunoglobulin in six patients aged 28-55 suffering from therapy-resistant metastatic cancer. More than 100 biochemical, hematological and immunological parameters, including nine tumor markers, were tested in blood samples taken 24 h after the first and up to 10 months after the last application. The intravenous application proceeded without serious adverse or side effects and did not require hospitalization. Cardiotoxicity was not observed. Four of six monitored patients attained stabilization of disease (liver ultrasound scan and bone computer tomography) with a very good quality of life lasting from seven up to 18 months. Positive response to the treatment was, among others, evaluated as decreased CA 15-3 and CEA tumor markers. In three of five tested patients the serum level of C-reactive protein was temporarily increased 72 h after the treatment. A stable or elevated number of peripheral blood reticulocytes together with activation of natural killer (NK) cells and lymphokine-activated killer (LAK) cells supports the data previously obtained in experimental animals pointing to a dual role, i.e. the cytotoxic and immunomobilizing character of doxorubicin-HPMA conjugates.

Abstract
Our goal is to define the properties of cell-impermeable cargo molecules that can be delivered into cells by pH (Low) Insertion Peptide (pHLIP), which can selectively target tumors in vivo based on their acidity. Using biophysical methods and fluorescence microscopy, we show that pHLIP can successfully deliver polar and membrane-impermeable cyclic peptides linked to its C terminus through the membranes of lipid vesicles and cancer cells. Our results also indicate that the translocation of these cargo molecules is pH dependent and mediated by transmembrane helix formation. Since a broad range of cell-impermeable molecules is excluded from discovery efforts because they cannot traverse membranes on their own, we believe that pHLIP has the potential to expand therapeutic options for acidic tissues such as tumors and sites of inflammation.

Abstract
The successful treatment of cancer with conventional drugs is frequently complicated by the resistance of tumor cells to such a non-specific therapy. Over the last few years, immunotherapy has gained attention as a tumor-specific approach. Recent findings demonstrated that some conventional cytostatics stimulate local anticancer responses. New anticancer drugs, including their polymeric derivatives, are currently being developed with the aim of destroying tumors more effectively and more specifically. Among these, the water-soluble conjugates of doxorubicin with N-(2-hydroxypropyl)methacrylamide (HPMA) copolymer carrier have emerged as efficient therapeutics because they are able to not only directly destroy cancer cells but also elicit systemic tumor-specific anticancer responses. Here, we discuss new insights into their mechanisms of immune surveillance, which could suggest novel approaches to cancer therapy.

Abstract
Synthesis, physicochemical behavior, tumor accumulation and preliminary anticancer activity of a new biodegradable graft copolymer-doxorubicin (DOX) conjugates designed for passive tumor targeting were investigated. In the graft high-molecular-weight conjugates the multivalent N-(2-hydroxypropyl)methacrylamide (HPMA) copolymer was grafted with a similar but semitelechelic HPMA copolymer; both types of polymer chains were bearing doxorubicin attached by hydrazone bonds enabling intracellular pH-controlled drug release. The polymer grafts were attached to the main chain through spacers, degradable enzymatically or reductively, facilitating, after the drug release, intracellular degradation of the graft polymer carrier to short fragments excretable from the organism by glomerular filtration. The graft polymer-DOX conjugate exhibited prolonged blood circulation and enhanced tumor accumulation in tumor-bearing mice indicating the important role of the EPR effect in the anticancer activity. The graft polymer-DOX conjugates showed a significantly higher antitumor activity in vivo than DOX.HCl or the linear polymer conjugate when tested in mice bearing 38C13 B-cell or EL4 T-cell lymphoma, with a significant number of long-term-surviving (LTS) mice with EL4 T-cell lymphoma treated with a single dose 15 mg DOX equiv./kg on day 10.

Abstract
Solid tumors often display metabolic abnormalities that consistently produce low pH in the extracellular space of poorly perfused tissue. These acidic regions may provide a mechanism for drug targeting. Peptides have been designed in such a manner that they exist in an anionic hydrophilic form at the pH of normal tissues, but then undergo a sharp transition to a non-ionic lipophilic form at reduced pH. Peptides were labeled with fluorescein or technetium-99m (99mTc) and evaluated in vitro and in two murine models of cancer. Our studies suggest that PAP-1, an 18 amino acid pH activated peptide with a pH of transition between hydrophilic and lipophilic forms (pT) of 6.4, will deliver fluorescein and 99mTc to tumors. Activation of PAP-1 by low pH and penetration into the plasma membrane of cells and tumors were confirmed using flow cytometry, fluorescence microscopy, and gamma scintigraphy. These results support our central hypothesis that PAP-1 may enable the selective delivery of macromolecules to tumors. This technology has potential for exploiting a common property of tumors to achieve highly specific medical intervention.

Abstract
Despite intensive study, the molecular mechanism for cell toxicity of N-(2-hydroxypropyl)methacrylamide (HPMA) copolymer-bound doxorubicin remains unclear. Moreover, the ability of the released drug to accumulate in the nucleus has also been questioned. We have hypothesized that the pattern of cell cycle progression is a useful indicator for the presence of free doxorubicin in the nucleus and its interaction with nuclear DNA. The effects of HPMA copolymer-bound doxorubicin on cell cycle progression were evaluated in this study in cultured human ovarian cancer A2780 cells. We determined that P-GFLG-DOX, but not P-GG-DOX, initiates cell cycle arrest and nuclear fragmentation in the same manner as free DOX, but with a time-delay. Our data indicate that drug release from the conjugate is required for the apoptotic activity associated with the conjugate.
