Polymeric Nanosystems Applied for Metal-Based Drugs and Photosensitizers Delivery: The State of the Art and Recent Advancements. Pharmaceutics 2022; 14:pharmaceutics14071506. [PMID: 35890401 PMCID: PMC9320085 DOI: 10.3390/pharmaceutics14071506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 07/03/2022] [Accepted: 07/12/2022] [Indexed: 11/17/2022] Open
Abstract
Nanotechnology-based approaches for targeting the delivery and controlled release of metal-based therapeutic agents have revealed significant potential as tools for enhancing the therapeutic effect of metal-based agents and minimizing their systemic toxicities. In this context, a series of polymer-based nanosized systems designed to physically load or covalently conjugate metal-based therapeutic agents have been remarkably improving their bioavailability and anticancer efficacy. Initially, the polymeric nanocarriers were applied for platinum-based chemotherapeutic agents resulting in some nanoformulations currently in clinical tests and even in medical applications. At present, these nanoassemblies have been slowly expanding for nonplatinum-containing metal-based chemotherapeutic agents. Interestingly, for metal-based photosensitizers (PS) applied in photodynamic therapy (PDT), especially for cancer treatment, strategies employing polymeric nanocarriers have been investigated for almost 30 years. In this review, we address the polymeric nanocarrier-assisted metal-based therapeutics agent delivery systems with a specific focus on non-platinum systems; we explore some biological and physicochemical aspects of the polymer–metallodrug assembly. Finally, we summarize some recent advances in polymeric nanosystems coupled with metal-based compounds that present potential for successful clinical applications as chemotherapeutic or photosensitizing agents. We hope this review can provide a fertile ground for the innovative design of polymeric nanosystems for targeting the delivery and controlled release of metal-containing therapeutic agents.

Abstract
Combination therapy has exhibited crucial potential in the treatment of cancers, especially in drug-resistant cancers. In this work, a novel tumor-targeted, redox dual-responsive and paclitaxel (PTX) loaded nanoparticle based on multifunctional dendrimer and lentinan was developed for combinational chemo-photodynamic therapy of PTX-resistant cancers. The nanoparticles exhibited enhanced cellular uptake and tumor penetration based on phenylboronic acid-sialic acid interactions, and had the ability to control drug release in response to intracellular high concentration of glutathione and H2O2. Specifically, light irradiation not only triggered the photodynamic effect of the nanoparticles for prominent photodynamic cytotoxicity, but also resulted in increased internalization and accelerated release of PTX into cytoplasm through the lysosome disruption, as well as the obvious damage to microtubules and actin microfilaments, for drug resistance reversal of A549/T cells. Meanwhile, PTX treatment would arrest cells in G2/M phase, thereby prolonging the period when nuclear membrane is broken down, which further facilitated photosensitizer accumulation in nuclei and improved DNA damage response. Consequently, the combination of PTX and photodynamic treatment lead to excellent antitumor effects to drug-resistant A549/T cells in vitro and in vivo, which provides a new strategy for the design of co-delivery system to overcome drug resistance.

Abstract
At present, malignant tumours have become one of the most serious diseases that endanger human health. According to a survey on causes of death in Chinese population in early 1990s, the malignant tumours were the second leading cause of death. In the treatment of tumours, the ideal situation is that drugs should target and accumulate at tumour sites and destroy tumour cells specifically, without affecting normal cells and stem cells with regenerative capacity. This requires drugs to be specifically transported to the target organs, tissues, cells, and even specific organelles, like mitochondria, nuclei, lysosomes, endoplasmic reticulum (ER), and Golgi apparatus (GA). The nano drug delivery system can not only protect drugs from degradation but also facilitate functional modification and targeted drug delivery to the tumour site. This article mainly reviews the targeting of nano drug delivery systems to tumour cytoplasmic matrix, nucleus, mitochondria, ER, and lysosomes. Organelle-specific drug delivery system will be a major mean of targeting drug delivery with lower toxicity, less dosage and higher drug concentration in tumour cells.

Abstract
Drug resistance arising from overexpressed efflux transporters increases the efflux of drugs and accordingly restricts the efficacy of chemotherapy. Advances in nanocarriers have provided potential strategies to cope with drug resistance. Herein, endogenous stimuli-responsive nucleus-targeted nanocarrier is developed for intracellular multidrug resistance protein 1 (MRP1) mRNA imaging and drug delivery. This nanocarrier (AuNP-mRS-DSs) is composed of three parts: (i) gold nanoparticle (AuNP), for loading DNA and quenching fluorescence; (ii) mRNA recognition sequence (mRS) modified on the surface of gold nanoparticle by gold-thiol bond, for the specific recognition of MRP1 mRNA; (iii) detachable subunit (DS), hybridized with Cy5-labeled DNA linker and nucleolin recognition motif and grafted onto mRS via the DNA linker for loading doxorubicin (Dox), binding to nucleolin, and reporting signal. First, nucleolin recognition motif of this nanocarrier targets nucleolin, which is overexpressed on cancer cells surface; subsequently, the whole nanocarrier enters the cell via nucleolin-mediated internalization. Subsequently, mRS will specifically recognize overexpressed MRP1 mRNA, leading to the release of trapped DS and followed by AuNP-quenched Cy5 fluorescence recovery. Finally, by translocation of nucleolin from cytoplasm to nucleus, the DS targets nucleus to delivery Dox. By intracellular fluorescence imaging, the differentiation of drug-resistant and nondrug-resistant cells could be achieved. Compared with free Dox (IC50 > 8.00 μM), Dox-loaded AuNP-mRS-DSs (IC50 = 2.20 μM) performed superior suppression efficacy toward drug-resistant cancer cells. Such a nanocarrier provides an effective strategy to synergistically sense and circumvent drug resistance, which may be exploited as a candidate for personalized medicine.

Abstract
Triple-negative breast cancer (TNBC) is one of the most invasively malignant human cancers and its incidence increases year by year. Effective therapeutics against them needs to be developed urgently. In this study, a kind of angiopep-2 modified and intelligently particle size-reducible NPs, Angio-DOX-DGL-GNP, was designed for accomplishing both high accumulation and deep penetration within tumor tissues. On one hand, for improving the cancerous targeting efficiency of NPs, angiopep-2 was anchored on the surface of NPs to facilitate their accumulation via binding with low density lipoprotein-receptor related protein (LRP) overexpressed on TNBC. On the other hand, for achieving high tumor retention and increasing tumor penetration, an intelligently particle size-reducible NPs were constructed through fabricating gelatin NPs (GNP) with doxorubicin (DOX) loaded dendrigraft poly-lysine (DGL). In vitro cellular uptake and ex-vivo imaging proved the tumor targeting effect of Angio-DOX-DGL-GNP. Additionally, the degradation of large-sized Angio-DOX-DGL-GNP by matrix metalloproteinase-2 (MMP-2) led to the size reduction from 185.7 nm to 55.6 nm. More importantly, the penetration ability of Angio-DOX-DGL-GNP after incubation with MMP-2 was dominantly enhanced in tumor spheroids. Due to a combinational effect of active targeting and deep tumor penetration, the tumor growth inhibition rate of Angio-DOX-DGL-GNP was 74.1% in a 4T1 breast cancer bearing mouse model, which was significantly higher than other groups. Taken together, we successfully demonstrated a promising and effective nanoplatform for TNBC treatment.

Abstract
While highly effective for slowing cancer progression in principle, the c-Myc inhibitor peptide H1-S6A,F8A (H1) has not performed well in tumor studies, in part because it does not pass efficiently through the nuclear envelope. Here we describe a dual-strike strategy in which tumor cells were treated first with N-(2-hydroxypropyl) methacrylamide (HPMA) copolymer-docetaxel (DTX) conjugates (P-DTX), which arrested cells in the G2/M phase and prolonged the period when the nuclear membrane was disassembled. In the second strike, the cells were then treated with P-H1 conjugates, which entered the nucleus and efficiently inhibited c-Myc. The in vitro studies demonstrated that the combination of P-DTX and P-H1 conjugates was sequence-dependent, and P-DTX followed by P-H1 had synergism, which was significantly more effective than reverse sequential delivery, simultaneous co-delivery or monotherapy with P-DTX or P-H1 alone. The in vivo studies showed that sequential delivery of P-DTX followed by P-H1 remarkably slowed the tumor growth and improved the animal survival. This sequential, dual-strike approach provides new opportunities for nuclear-targeted anticancer drug delivery.

Abstract
The kinetics of toxicity of doxorubicin (Dox) and gold nanoparticle-conjugated doxorubicin (Au-Dox) were investigated in cultured B16 melanoma cells and cardiomyocytes using real-time cell-growth imaging. Both bolus exposure and continuous exposure were used. Modeling of the growth curve dynamics suggested patterns of uptake and/or expulsion of the drug that were different for the different cell lines and exposures. Dox alone in B16 cells fit to a model of slow drug buildup, whereas Au-Dox fit to a pattern of initial high drug efficacy followed by a decrease. In cardiomyocytes, the best fit was to a model of increasing drug concentration which then began to decrease, consistent with breakdown of the doxorubicin in solution. Cardiomyocytes were more sensitive than B16 cells to Dox alone (IC50 123 ± 2 nM vs. 270 ± 2 nM with continuous exposure), but were dramatically less sensitive to Au-Dox (IC50 1 ± 0.1 μM vs. 58 ± 5 nM with continuous exposure). Bolus exposure for 40 min led to significant cell death in B16 cells but not in cardiomyocytes. Fluorescence lifetime imaging (FLIM) showed different patterns of uptake of Au-Dox in the two cell types that explained the differential toxicity. While Au-Dox concentrated in the nuclei of B16 cells, it remained endosomal in cardiomyocytes. These results suggest that stable conjugates of nanoparticles to doxorubicin may be useful for treating resistant cancers while sparing healthy tissue.

Abstract
Chitosan nanoparticles are promising drug delivery vehicles. However, the conventional method of unregulated mixing during ionic gelation limits their application because of heterogeneity in size and physicochemical properties. Therefore, a detailed theoretical analysis of conventional and active microreactor models was simulated. This led to design and fabrication of a polydimethylsiloxane microreactor with magnetic micro needles for the synthesis of monodisperse chitosan nanoparticles. Chitosan nanoparticles synthesized conventionally, using 0.5 mg/mL chitosan, were 250 ± 27 nm with +29.8 ± 8 mV charge. Using similar parameters, the microreactor yielded small size particles (154 ± 20 nm) at optimized flow rate of 400 μL/min. Further optimization at 0.4 mg/mL chitosan concentration yielded particles (130 ± 9 nm) with higher charge (+39.8 ± 5 mV). The well-controlled microreactor-based mixing generated highly monodisperse particles with tunable properties including antifungal drug entrapment (80%), release rate, and effective activity (MIC, 1 μg/mL) against Candida.

Beyond the contaminated zone Fe(0) can be expected to have oxidized and Carbo-Iron was used in its oxidized form in ecotoxicological tests. Potential effects of Carbo Iron in zebrafish (Danio rerio) were investigated using a 48 h embryo toxicity test under static conditions, a 96 h acute test with adult fish under semi-static conditions and a 34 d fish early life stage test (FELST) in a flow-through system. Particle diameters in test suspensions were determined via dynamic light scattering (DLS) and ranged from 266 to 497 nm. Particle concentrations were measured weekly in samples from the FELST using a method based on the count rate in DLS. Additionally, uptake of particles into test organisms was investigated using microscopic methods. Furthermore, effects of Carbo-Iron on gene expression were investigated by microarray analysis in zebrafish embryos. In all tests performed, no significant lethal effects were observed. Furthermore, Carbo-Iron had no significant influence on weight and length of fish as determined in the FELST. In the embryo test and the early life stage test, growth of fungi on the chorion was observed at Carbo-Iron concentrations between 6.3 and 25mg/L. Fungal growth did not affect survival, hatching success and growth. In the embryo test, no passage of Carbo-Iron particles into the perivitelline space or the embryo was observed. In juvenile and adult fish, Carbo-Iron was detected in the gut at the end of exposure. In juvenile fish exposed to Carbo-Iron for 29 d and subsequently kept for 5d in control water, Carbo-Iron was no longer detectable in the gut. Global gene expression in zebrafish embryos was not significantly influenced by Carbo-Iron.

Abstract
Three half-sandwich iridium and ruthenium organometallic complexes with high cytotoxicity are synthesized, and their anticancer mechanisms are elucidated. The organometallic complexes can interact with DNA through coordination or intercalation, thereby inducing apoptosis and inhibiting proliferation of resistant cancer cells. The organometallic complexes are then incorporated into polymeric micelles through the polymer-metal coordination between poly(ethylene glycol)-b-poly(glutamic acid) [PEG-b-P(Glu)] and organometallic complexes to further enhance their anticancer effects as a result of the enhanced permeability and retention effect. The micelles with particle sizes of ≈60 nm are more efficiently internalized by cancer cells than the corresponding complexes, and selectively dissociate and release organometallic anticancer agents within late endosomes and lysosomes, thereby enhancing drug delivery to the nuclei of cancer cells and facilitating their interactions with DNA. Thus, the micelles display higher antitumor activity than the organometallic complexes alone with a lack of the systemic toxicity in a mouse xenograft model of cisplatin-resistant human ovarian cancer. These results suggest that the polymeric micelles carrying anticancer organometallic complexes provide a promising platform for the treatment of resistant ovarian cancer and other hard-to-treat solid tumors.

Abstract
Nanoscale drug delivery systems have been widely investigated due to their well-recognized advantages including controlled delivery of chemotherapeutic agents, enhanced therapeutic effectiveness, and reduced adverse effects compared to conventional chemotherapy with small molecules. However, further progress in the use of nanoscale delivery systems in clinical applications has been hampered by pharmacokinetic studies in biological samples which were associated with significant experimental challenges. Here, we report a rational ratiometric approach to monitor drug release kinetics by quantitatively investigating luminescence resonance energy transfer (LRET) from upconversion nanoparticles to the antitumor drug doxorubicin (DOX). Specifically, DOX molecules within the shell of mesoporous silica-coated upconversion nanoparticles selectively quenched the green emission of upconversion nanoparticles, while the intensity of red emission was essentially unaltered. Consequently, when DOX was gradually released, a steady recovery of green emission was observed. The ability to monitor the intensity ratio of green-to-red luminescence enabled a rational design for real-time investigation of drug delivery release kinetics. Importantly, the internal standard effect of red emission made this ratiometric approach suitable for complex biological microenvironments.

Abstract
As an emerging nanomaterial, bismuth oxychloride (BiOCl) has attracted explosive interests in diverse areas. However, how it interfaces with biological systems, particularly its interaction with human cells and the resulting effects are completely unknown. In this paper, the cytotoxicity of BiOCl nanosheets (NSs) was investigated toward a human skin derived cell line (HaCaT). It was found that BiOCl-NSs had no cytotoxicity at low concentrations (<0.5 µg/mL), whereas higher concentrations (5-100 µg/mL) of BiOCl-NSs could trigger toxic effects on HaCaT cells, with changes in cell morphology and impairment of intracellular structures (mitochondria and cytoskeleton). BiOCl-NSs also led to cell apoptosis and cells cycle arrest in G0/G1 phase. Flow cytometric data showed that BiOCl-NSs were effectively incorporated into HaCaT cells. Transmission electron microscope (TEM) images further revealed that BiOCl-NSs sequestered in the lysosomes, mitochondria, nuclei, and vesicles. Results of DCFH-DA assay and nutritional antioxidant N-acetylcysteine (NAC) experiments suggested that an oxidative stress mechanism was involved in the cytotoxic effects of BiOCl-NSs. Taken together, this work represents the first study on the behavior of BiOCl-NSs on human cells, and constitutes the first and essential step for the risk assessment of BiOCl nanomaterials.

Abstract
The interfacing of colloidal nanoparticles with mammalian cells is now well into its second decade. In this review our goal is to highlight the more generally accepted concepts that we have gleaned from nearly twenty years of research. While details of these complex interactions strongly depend, amongst others, upon the specific properties of the nanoparticles used, the cell type, and their environmental conditions, a number of fundamental principles exist, which are outlined in this review.

Abstract
Graphene oxide (GO) can be potentially used in biomedical and nonbiomedical products. The in vivo studies have demonstrated that GO is predominantly deposited in the lung. In the present study, we employed SOLiD sequencing technique to investigate the molecular control of in vitro GO toxicity in GLC-82 pulmonary adenocarcinoma cells by microRNAs (miRNAs), a large class of short noncoding RNAs acting to post-transcriptionally inhibit gene expression. In GLC-82 cells, GO exposure at concentrations more than 50 mg/L resulted in severe reduction in cell viability, induction of lactate dehydrogenase leakage, reactive oxygen species production and apoptosis, and dysregulation of cell cycle. GO was localized in cytosol, mitochondria, endoplasmic reticulum, and nucleus of cells. Based on SOLiD sequencing, we identified 628 up-regulated and 25 down-regulated miRNAs in GO-exposed GLC-82 cells. Expression of some selected dysregulated miRNAs was concentration-dependent in GO-exposed GLC-82 cells. The dysregulated miRNAs and their predicted targeted genes were involved in many biological processes. By combining both information on targeted genes for dysregulated miRNAs and known signaling pathways for apoptosis control, we hypothesize that the dysregulated miRNAs could activate both a death receptor pathway by influencing functions of tumor necrosis factor α receptor and caspase-3 and a mitochondrial pathway by affecting functions of p53 and Bcl-2 in GO-exposed GLC-82 cells. Our results provide an important molecular basis at the miRNA level for explaining in vitro GO toxicity. Our data will be also useful for developing new strategies to reduce GO toxicity such as surface chemical modification.

Abstract
Multidrug resistance (MDR) is a major obstacle to successful cancer therapy, especially for chemotherapy. The new drug delivery system (DDS) provides promising approaches to reverse MDR, for which the poor cellular uptake and insufficient intracellular drug release remain rate-limiting steps for reaching the drug concentration level within the therapeutic window. Stimulus-coupled drug delivery can control the drug-releasing pattern temporally and spatially, and improve the accumulation of chemotherapeutic agents at targeting sites. In this review, the applications of DDS which is responsive to different types of stimuli in MDR cancer therapy is introduced, and the design, construction, stimuli-sensitivity and the effect to reverse MDR of the stimuli-responsive DDS are discussed.

Abstract
Giant multiarm polymers with and without β-cyclodextrin (β-CD) end groups were synthesized. Further, the former was assembled into nanoparticles via a β-CD/adamantane inclusion complex. The incorporation of an esterase-sensitive linker in the inclusion complex enables the nanoparticles to decompose to the multiarm polymer again through the hydrolysis of ester linkage, making the nanoparticles have the characteristics of multistage nanovectors.
