Abstract
Phototherapies, including photothermal therapy and photodynamic therapy, have gained booming development over the past several decades for their attractive non-invasiveness nature, negligible adverse effects, minimal systemic toxicity, and high spatial selectivity. Phototherapy usually requires three components: light irradiation, photosensitizers, and molecular oxygen. Photosensitizers can convert light energy into heat or reactive oxygen species, which can be used in the tumor-killing process. The direct application of photosensitizers in tumor therapy is restricted by their poor water solubility, fast clearance, severe toxicity, and low cellular uptake. The encapsulation of photosensitizers into nanostructures is an attractive strategy to overcome these critical limitations. Poly(glutamic acid) (PGA) is a kind of poly(amino acid)s containing the repeating units of glutamic acid. PGA has superiority for cancer treatment because of its good biocompatibility, low immunogenicity, and modulated pH responsiveness. The hydrophilicity nature of PGA allows the physical entrapment of photosensitizers and anticancer drugs via the construction of amphiphilic polymers. Moreover, the pendent carboxyl groups of PGA enable chemical conjugation with therapeutic agents. In this mini-review, we highlight the stateof- the-art design and fabrication of PGA-based nanoplatforms for phototherapy. We also discuss the potential challenges and future perspectives of phototherapy, and clinical translation of PGA-based nanomedicines.

Abstract
The treatment of malignancies has undergone dramatic changes in the past few decades. Advances in drug delivery techniques and nanotechnology have allowed for new formulations of old drugs, so as to improve the pharmacokinetics, to enhance accumulation in solid tumors, and to reduce the significant toxic effects of these important therapeutic agents. Here, we review the published clinical data in cancer therapy of several major drug delivery systems, including targeted radionuclide therapy, antibody-drug conjugates, liposomes, polymer-drug conjugates, polymer implants, micelles, and nanoparticles. The clinical outcomes of these delivery systems from various phases of clinical trials are summarized. The success and limitations of the drug delivery strategies are discussed based on the clinical observations. In addition, the challenges in applying drug delivery for efficacious cancer therapy, including physical barriers, tumor heterogeneity, drug resistance, and metastasis, are discussed along with future perspectives of drug delivery in cancer therapy. In doing so, we intend to underscore that efficient delivery of cancer therapeutics to solid malignancies remains a major challenge in cancer therapy, and requires a multidisciplinary approach that integrates knowledge from the diverse fields of chemistry, biology, engineering, and medicine. The overall objective of this review is to improve our understanding of the clinical fate of commonly investigated drug delivery strategies, and to identify the limitations that must be addressed in future drug delivery strategies, toward the pursuit of curative therapies for cancer.

Abstract
The progress in medical research has led to the understanding that cancer is a large group of heterogeneous diseases, with high variability between and within individuals. This variability sprouted the ambitious goal to improve therapeutic outcomes, while minimizing drug adverse effects through stratification of patients by the differences in their disease markers, in a personalized manner, as opposed to the strategy of "one therapy fits all". Nanotheranostics, composed of nanoparticles (NPs) carrying therapeutic and/or diagnostics probes, have the potential to revolutionize personalized medicine. There are different modalities to combine these two distinct fields into one system for a synergistic outcome. The addition of a nanocarrier to a theranostic system holds great promise. Nanocarriers possess high surface area, enabling sophisticated functionalization with imaging agents, thus gaining enhanced diagnostic ability in real-time. Yet, most of the FDA-approved theranostic approaches are based on small molecules. The theranostic approaches that are reviewed herein are paving the road towards personalized medicine through all stages of patient care: starting from screening and diagnostics, proceeding to treatment and ending with treatment follow-up. Our current review provides a broad background and highlights new insights for the rational design of theranostic nanosystems for desired therapeutic niches, while summoning the hurdles on their way to become first-line diagnostics and therapeutics for cancer patients.

Abstract
The convergent synthesis and characterization of a potential theranostic agent, [DPP-ZnP-GdDOTA](-), which combines a diketopyrrolopyrrole-porphyrin component DPP-ZnP as a two-photon photosensitizer for photodynamic therapy (PDT) with a gadolinium(III) DOTA complex as a magnetic resonance imaging probe, is presented. [DPP-ZnP-GdDOTA](-) has a remarkably high longitudinal water proton relaxivity (19.94 mm(-1) s(-1) at 20 MHz and 25 °C) for a monohydrated molecular system of this size. The Nuclear Magnetic Relaxation Dispersion (NMRD) profile is characteristic of slow rotation, related to the extended and rigid aromatic units integrated in the molecule and to self-aggregation occurring in aqueous solution. The two-photon properties were examined and large two-photon absorption cross-sections around 1000 GM were determined between 910 and 940 nm in DCM with 1 % pyridine and in DMSO. Furthermore, the new conjugate was able to generate singlet oxygen, with quantum yield of 0.42 and 0.68 in DCM with 1 % pyridine and DMSO, respectively. Cellular studies were also performed. The [DPP-ZnP-GdDOTA](-) conjugate demonstrated low dark toxicity and was able to induce high one-photon and moderate two-photon phototoxicity on cancer cells.

Abstract
To improve the poor water solubility of sorafenib and to monitor its distribution and the early feedback effects on its in vivo treatment efficacy in a precise manner, sorafenib (SF) and gadolinium (Gd) co-loaded liposomes (SF/Gd-liposomes) were prepared. The simultaneous imaging and therapy efficacies of the SF/Gd-liposomes were tested. The solubility of SF in SF/Gd-liposomes was significantly increased from 0.21 μg/mL to 250 μg/mL. The imaging capability of SF/Gd-liposomes were tested by in-vitro and the in-vivo imaging ability tests and the results confirmed that SF/Gd-liposomes could be served as an effective contrast agent. The design of SF/Gd-liposomes allowed the MRI-guided in vivo visualization of the delivery and biodistribution of liposome. In the in vivo antitumor studies, SF/Gd-liposomes had better antitumor effects in H22 tumor-bearing mice than SF solution (oral or i.v. administration) (P<0.05). These findings indicated that the SF/Gd-liposomes could be used as the promising nano-carriers for the MRI-guided in vivo visualization of the delivery and HCC treatment.

Abstract
The antitumor effect of photodynamic therapy (PDT) mediated by a novel photosensitizer I (Ps I; {γ-[N-poly(ethyleneglycol)]folic acid}-5,10,15-tris(3-hydroxyphenyl)-20-(4-carboxyphenyl)chlorin), in which chlorin was used as a photoactive unit, folic acid as a tumor‑targeting warhead, and polyethylene glycol as a linker, on cervical carcinoma was studied in vitro and in vivo. Ps I exhibited a considerably higher cellular uptake by HeLa cells than folic acid-free analogue Ps A (tert-butyl N-poly(ethyleneglycol)ethylcarbamate-5,10,15-tris(3-hydroxyphenyl)-20-(4-carboxyphenyl)chlorin), and the cellular uptake by HeLa cells of Ps I could be competitively inhibited by excess folic acid. Moreover, at different time points after the intravenous (i.v.) injection of Ps I and A, Ps I produced a >2-fold higher tumor to normal tissue ratio in tumor-bearing nude mice as compared to Ps A. MTT assay indicated that the HeLa cell proliferation inhibition ratio was increased 34% after Ps I-PDT compared with Ps A-PDT with a photosensitizer concentration of 15.2 µmol/l. Administration of Ps I (7 mg/kg, i.v.) followed by light exposure (80 J/cm2) markedly suppressed the growth of xenograft tumors, and the tumor volume was 10-fold smaller than that of the control group. Tumor growth inhibition in vitro and in vivo had an obvious dependency on the Ps I concentration and irradiation dose. The mode of cell death post-Ps I-PDT was analyzed by flow cytometry, confocal laser scanning microscopy, and electron microscope, and the results suggested that apoptosis was the primary mode of HeLa cell death induced by Ps I-PDT. The results also demonstrated that tumor targeting of Ps I was clearly improved because of the endocytosis mediated by the folate receptor. As a result, Ps I-PDT exhibited higher antitumor activity than Ps A-PDT and has potential as an alternative treatment modality for cervical cancer.

Abstract
Aqueous bifunctional semiconductor polymer nanoparticles (SPNs), approximately 30 nm in diameter (as measured from electron microscopy), were synthesised using hydrophobic conjugated polymers, amphiphilic phospholipids and a gadolinium-containing lipid. Their fluorescence quantum yields and extinction coefficients were determined, and their MRI T₁-weighted relaxation times in water were measured. The bimodal nanoparticles were readily taken up by HeLa and murine macrophage-like J774 cells as demonstrated by confocal laser scanning microscopy, and were found to be MRI-active, generating a linear relationship between T₁-weighted relaxation rates and gadolinium concentrations The synthesis is relatively simple, and can easily result in milligrams of materials, although we fully expect scale-up to the gram level to be easily realised.

Abstract
The advent of nanoparticle DDSs (drug delivery systems, nano-DDSs) is opening new pathways to understanding physiology and pathophysiology at the nanometer scale. A nano-DDS can be used to deliver higher local concentrations of drugs to a target region and magnify therapeutic effects. However, interstitial cells or fibrosis in intractable tumors, as occurs in pancreatic or scirrhous stomach cancer, tend to impede nanoparticle delivery. Thus, it is critical to optimize the type and size of nanoparticles to reach the target. High-resolution 3D imaging provides a means of "seeing" the nanoparticle distribution and therapeutic effects. We introduce the concept of "nano-pathophysiological imaging" as a strategy for theranostics. The strategy consists of selecting an appropriate nano-DDS and rapidly evaluating drug effects in vivo to guide the next round of therapy. In this article we classify nano-DDSs by component carrier materials and present an overview of the significance of nano-pathophysiological MRI.

Co-delivery of doxorubicin and RNA using pH-sensitive poly (β-amino ester) nanoparticles for reversal of multidrug resistance of breast cancer. Biomaterials 2014; 35:6047-59. [PMID: 24797883 DOI: 10.1016/j.biomaterials.2014.04.025] [Citation(s) in RCA: 104] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2014] [Accepted: 04/08/2014] [Indexed: 01/19/2023]
Abstract
An appropriate co-delivery system for chemotherapeutic agents and nucleic acid drugs will provide a more efficacious approach for the treatment of breast cancer by reversing multidrug resistance (MDR). In this work, a new amphiphilic poly (β-amino ester), poly[(1,4-butanediol)-diacrylate-β-5-polyethylenimine]-block-poly[(1,4-butanediol)-diacrylate-β-5-hydroxy amylamine] (PDP-PDHA) was synthesized, and the doxorubicin (DOX) and survivin-targeting shRNA (shSur) co-loading nanoparticle (PDNs) were prepared. The pH-sensitive poly[(1,4-butanediol) diacrylate-β-5-hydroxy amylamine] (PDHA) endowed PDNs both pH-triggered drug release characteristics and enhanced endo/lysosomal escape ability, thus improving the cytotoxicity of DOX and the transfection efficiency. PDNs also increased the DOX accumulation, down-regulated 57.7% survivin expression, induced 80.8% cell apoptosis and changed the cell cycle in MCF-7/ADR cells. In the MCF-7/ADR tumor-bearing mice models, after administrated intravenously, PDNs raised the accumulation of DOX and shSur in the tumor tissue by 10.4 and 20.2 folds, respectively, resulting in obvious inhibition of the tumor growth with tumor inhibiting rate of 95.9%. The combination of DOX and RNA interference showed synergistic effect on overcoming MDR. Therefore, PDNs could be a promising co-delivery vector for effective therapy of drug resistant breast cancer.

Abstract
INTRODUCTION Drug therapy is frequently limited by the widespread biodistribution of the active agents and the little specificity for non-healthy cells. Therefore, inadequate drug concentrations result into the site of action, and severe toxicity may also arise. To address the problem, liposome-based medicines have tried to improve pharmacotherapy. AREAS COVERED The review provides an updated revision of the lately published patents covering recent advances in liposome-based drug delivery. They are principally related to the control of drug biodistribution by using stealth, stimuli-sensitive and/or liposomal structures surface modified for ligand-mediated delivery. The contribution further highlights liposome-based theranosis. EXPERT OPINION Liposomes have received great attention given their biocompatibility, biodegradability and targetability. From 2007 to present date, patent publications related to their use in drug delivery have shown the move towards more stable structures with optimized drug delivery capabilities, further combining passive and active targeting concepts to gain control of the in vivo fate. However, the introduction of all these liposomal structures in the disease arena is still a challenge. Two key aspects are the difficulty of identifying easy and economic synthesis conditions which can be scaled up in the pharmaceutical industry, and the need for complementary investigations illustrating risks of toxicity/immunogenicity.

Abstract
Polymer-based nanomedicine is a large and fast growing field. Polymer-based systems have been extensively used as therapeutic carriers as well as bioimaging agents for example in tumour diagnosis. However, fewer polymeric systems have been able to combine both therapy and imaging in a new field that is called theranostics (theragnostics). This review aims to summarise the recent developments and trends on polymeric theranostics. Four different types of therapies/treatments are examined namely drug delivery, gene delivery, photodynamic therapy and hyperthermia treatment combined with different imaging moieties like magnetic resonance imaging agents, fluorescent agents and microbubbles for ultrasound imaging.

Abstract
Multifunctional nanoparticles (NPs) were prepared based on temperature-induced phase transition in a molten mixture of Lipiodol(®), Tween 80, paclitaxel (PTX), and Pluronic F-68, wherein the Lipiodol(®)/Tween 80 mixture is used as a solubilizer for PTX, and Pluronic F-68 is used for the stabilization of the molten mixture. The morphology and size distribution of optimized multifunctional NPs were observed using transmittance electron microscopy (TEM) and a particle size analyzer. In the optical imaging of tumor-bearing mice using a near-infrared fluorescence (NIRF) imaging system, the multifunctional NPs were evaluated in terms of a time-dependent excretion profile, in vivo biodistribution and tumor-targeting capability compared to free fluorescence dye. In addition, the prolonged circulation of multifunctional NPs was confirmed by enhancement of the blood-pool in live animals using a micro-CT imaging system, because iodine-containing Lipiodol(®) has an X-ray enhancement property. Finally, the anti-tumor efficacy of multifunctional NPs was monitored by injecting the multifunctional NPs into the tail veins of tumor-bearing mice. The multifunctional NPs showed excellent tumor targetability and anti-tumor efficacy in tumor-bearing mice, caused by the enhanced permeation and retention (EPR) effect.

Abstract
Macromolecular contrast agents have the potential to assist magnetic resonance imaging (MRI) due to their high relaxivity, but are not clinically useful because of toxicity due to poor clearance. We have prepared a biodegradable ketal-based polymer contrast agent which is designed to degrade rapidly at physiological pH by hydrolysis, facilitating renal clearance. In vitro, the agent degraded more rapidly at lower pH, with complete fragmentation after 24 h at pH 7.4. In vitro relaxivity measurements showed a direct correlation between molecular weight and relaxivity. We compared our polymer contrast agent with commercially available Magnevist in vivo by MRI imaging, as well as measuring the Gd concentration in blood. Our results show that our polymer contrast agent gives a higher contrast and intensity in the same organs and areas as Magnevist and is cleared from the blood at a similar rate. We aim to improve our polymer contrast agent design to develop it for use as a MRI contrast agent, and explore its use as a platform for other imaging modalities.

Abstract
A novel folate-porphyrin conjugate 1 for targeted photodynamic therapy of tumor was designed and synthesized. The results of fluorescence spectroscopy and confocal laser scanning microscope demonstrated that the cellular uptake of conjugate 1 by HeLa cells was 35 times higher than that of precursor porphyrin 3 after 24 h incubation, and that the presence of excessive free folic acid inhibited the cellular uptake of conjugate 1. Cytotoxicity against folate-receptor positive HeLa cells in vitro measured by MTT assay demonstrated that conjugate 1 exhibited much lower dark cytotoxicity but significant photocytotoxicity, with 86.4% of cell growth inhibition ratio after irradiation. However, conjugate 1 induced lower photocytotoxicity for normal cells and folate-receptor negative cells. These results suggest that folate-porphyrin like photosensitizers could induce a potentially useful targeted photodynamic therapy modality for folate-receptor-positive cancer cells due to the folate-receptor mediated endocytosis.

Abstract
Photodynamic therapy (PDT) is an emerging clinical modality for the treatment of a variety of diseases. Most photosensitizers are hydrophobic and poorly soluble in water. Many new nanoplatforms have been successfully established to improve the delivery efficiency of PS drugs. However, few reported studies have investigated how the carrier microenvironment may affect the photophysical properties of photosensitizer (PS) drugs and subsequently, their biological efficacy in killing malignant cells. In this study, we describe the modulation of type I and II photoactivation processes of the photosensitizer, 5,10,15,20-tetrakis(meso-hydroxyphenyl)porphyrin (mTHPP), by the micelle core environment. Electron-rich poly(2-(diisopropylamino)ethyl methacrylate) (PDPA) micelles increased photoactivations from type II to type I mechanisms, which significantly increased the generation of O(2)(-) through the electron transfer pathway over (1)O(2) production through energy transfer process. The PDPA micelles led to enhanced phototoxicity over the electron-deficient poly(D,L-lactide) control in multiple cancer cell lines under argon-saturated conditions. These data suggest that micelle carriers may not only improve the bioavailability of photosensitizer drugs, but also modulate photophysical properties for improved PDT efficacy.

Abstract
The development of gadolinium chelators that can be easily and readily linked to various substrates is of primary importance for the development high relaxation efficiency and/or targeted magnetic resonance imaging (MRI) contrast agents. Over the last 25 years a large number of bifunctional chelators have been prepared. For the most part, these compounds are based on ligands that are already used in clinically approved contrast agents. More recently, new bifunctional chelators have been reported based on complexes that show a more potent relaxation effect, faster complexation kinetics and in some cases simpler synthetic procedures. This review provides an overview of the synthetic strategies used for the preparation of bifunctional chelators for MRI applications.

Abstract
Modern polymer chemistry has led to the generation of a number of biocompatible synthetic polymers that have been increasingly studied as efficient carriers for drugs and imaging agents. Synthetic biocompatible polymers have been used to improve the efficacy of both small-molecular-weight therapeutics and imaging agents. Furthermore, multiple targeted anticancer agents and/or imaging reporters can be attached to a single polymer chain, allowing multifunctional and/or multimodality therapy and molecular imaging. Having both an anticancer drug and an imaging reporter in a single polymer chain allows noninvasive real-time visualization of the pharmacokinetics of polymeric drug delivery systems, which can uncover and explain the complicated mechanisms of in vivo drug delivery and their correlation to pharmacodynamics. This review examines the use of the synthetic biocompatible polymer poly(L-glutamic acid) (PG) as an efficient carrier of cancer therapeutics and imaging agents. This review summarizes and updates our recent research on the use of PG as a platform for drug delivery and molecular imaging, including recent clinical findings with respect to PG-paclitaxel (PG-TXL), the combination of PG-TXL with radiotherapy, mechanisms of action of PG-TXL, and noninvasive visualization of in vivo delivery of polymeric conjugates with contrast-enhanced magnetic resonance imaging, optical imaging, and multimodality imaging.

Abstract
PURPOSE The aim of this study was to evaluate stability and Gd tissue distribution of a biodegradable macromolecular MRI contrast agent, GDCC. METHODS Kinetic stability of GDCC was evaluated based on transmetallation with endogenous metal ions Zn2+ and Cu2+ in rat plasma in comparison with Omniscan, MultiHance and ProHance. In vivo transmetallation of GDCC was evaluated by determining metal content in the urine samples of Spague-Dawley rats. The biodistribution of the agents was determined in rats at 48 h post-injection. RESULTS A new method of using ultrafiltration was developed for study of kinetic stability against transmetallation of Gd(III)-based MRI contrast agents. Both in vitro and in vivo stability of the contrast agents towards transmetallation with Zn2+ were in the order of ProHance > MultiHance approximately GDCC > Omniscan. No significant transmetallation with Cu2+ was observed for the contrast agents. GDCC had comparable retention to the control agents in most organs and tissues with slightly high retention in the liver and kidneys at 48 h post-injection. CONCLUSION Ultrafiltration is efficient and accurate for characterizing the kinetic stability of Gd(III)-based MRI contrast agents. The novel biodegradable macromolecular contrast agent GDCC is promising for further development for contrast enhanced MRI.

Abstract
Theranostics, the fusion of therapy and diagnostics for optimizing efficacy and safety of therapeutic regimes, is a growing field that is paving the way towards the goal of personalized medicine for the benefit of patients. The use of light as a remote-activation mechanism for drug delivery has received increased attention due to its advantages in highly specific spatial and temporal control of compound release. Photo-triggered theranostic constructs could facilitate an entirely new category of clinical solutions which permit early recognition of the disease by enhancing contrast in various imaging modalities followed by the tailored guidance of therapy. Finally, such theranostic agents could aid imaging modalities in monitoring response to therapy. This article reviews recent developments in the use of light-triggered theranostic agents for simultaneous imaging and photoactivation of therapeutic agents. Specifically, we discuss recent developments in the use of theranostic agents for photodynamic-, photothermal- or photo-triggered chemotherapy for several diseases.

Abstract
A new versatile hybrid nanocarrier has been designed using a "soft chemistry" synthesis, to efficiently encapsulate a photosensitizer - the protoporphyrin IX (Pp IX) - while preserving its activity intact in biological environment for advantageous use in photodynamic therapy (PDT). The synthesized Pp IX silica-based nanocarriers show to be spherical in shape and highly monodisperse with size extending from 10 nm up to 200 nm according to the synthesis procedure. Upon laser irradiation, the entrapped Pp IX shows to efficiently deliver reactive oxygen species (ROS) which are responsible for damaging tumor tissues. The ability of Pp IX silica-based nanocarriers to induce tumor cell death has been tested successfully in vitro. The stability of the Pp IX silica-based nanocarriers has been followed by UV-vis absorption and fluorescence emission in aqueous media and in 100% mouse serum media. The flexibility of the nanocarrier silica core has been examined as the key parameter to tune the Pp IX stability in biological environment. Indeed, an additional biocompatible inorganic surface coating performed on the Pp IX silica-based nanocarriers to produce an optimized bilayer coating demonstrates to significantly enhance the Pp IX stabilization in biological environments. Such versatile hybrid nanocarriers open new perspectives for PDT.

The phosphonate-terminated silica nanoparticles, entrapping water-soluble photosensitizer MB (MB-encapsulated PSiNPs), are synthesized by the controlled synchronous hydrolysis of tetraethoxysilane and trihydroxyl silyl propyl methyl phosphonate in the water-in-oil microemulsion. The resulting MB-encapsulated PSiNPs effectively prevent the leakage of entrapped MB from the particles and provide protection for against reduction by diaphorase. Enough dose of irradiation to the MB-encapsulated PSiNPs under the light of 635 nm results in efficient generation of singlet oxygen and induces photodynamic damage to Hela cells. Furthermore, the non-invasive visualization of MB-encapsulated PSiNPs in mice under the in vivo imaging system confirmed the MB-encapsulated PSiNPs also presents near-infrared luminescence for in vivo imaging. And the effect of the PDT toward the xenograft tumor in vivo is exciting after imaging the MB-encapsulated PSiNPs injected tumor using in vivo optical imaging system. Thus, the single particle platform is effective for simultaneous in vivo imaging and photodynamic therapy without using extra agent, which can provide image-guidance for site-specific photodynamic therapy.

Abstract
Multifunctional nanomedicine is emerging as a highly integrated platform that allows for molecular diagnosis, targeted drug delivery, and simultaneous monitoring and treatment of cancer. Advances in polymer and materials science are critical for the successful development of these multi-component nanocomposites in one particulate system with such a small size confinement (<200 nm). Currently, several nanoscopic therapeutic and diagnostic systems have been translated into clinical practice. In this feature article, we will provide an up-to-date review on the development and biomedical applications of nanocomposite materials for cancer diagnosis and therapy. An overview of each functional component, i.e. polymer carriers, MR imaging agents, and therapeutic drugs, will be presented. Integration of different functional components will be illustrated in several highlighted examples to demonstrate the synergy of the multifunctional nanomedicine design.
