Abstract
Intelligent polymeric micelles with fluorescence imaging feature have been emerged as promising tools for theranostics. However, conventional fluorescent dyes are limited by short wavelength excitation, interference of tissue autofluorescence, limited imaging depth and quenched emission in aggregation state. Methods: We synthesized a novel mPEG-SS-Poly (AEMA-co-TBIS) (mPEATss) copolymer to develop multifunctional polymeric micelles with great AIE feature for cancer therapy and AIE active two-photon bioimaging. The stimuli-responsive behavior and AIE active two-photon cell and tissue imaging as well as in vitro and in vivo antitumor ability of DOX-loaded mPEATss were studied. Results: mPEATss micelles showed excellent AIE active two-photon cell imaging ability and deep tissue imaging ability. Antitumor drug DOX could be encapsulated to form a drug-loaded micellar system with a small diameter of 65 nm. The disassembly and charge-conversion of mPEATss micelles could be triggered by acidic environment, resulting in accelerated drug release and great antitumor efficacy. In vivo, ex vivo imaging and in vivo pharmacokinetic study demonstrated that mPEATss micelles could efficiently accumulate in tumor sites, which ensured ideal anticancer effect. Conclusions: This pH and redox dual responsive and AIE active two-photon imaging polymeric micelles would be a promising candidate for theranostics.

Abstract
Here, we constructed a nanostructured pH/redox dual-responsive supramolecular drug carrier with both aggregation-induced emission (AIE) and Forster resonance energy transfer (FRET) effects, which enabled selective drug release and monitoring drug delivery and release processes. Taking the hyperbranched polyamide amine (H-PAMAM) with intrinsic AIE effects as the core, poly(ethylene glycol) (PEG) was bridged on its periphery by dithiodipropionic acid. Then, through the host-guest interaction of PEG and α-cyclodextrin, the supramolecular nanoparticles with AIE effects were constructed to load the anticancer drug doxorubicin (DOX). The supramolecular assembly has sufficiently large DOX loading due to the abundant cavities formed by branched structures. The hyperbranched core H-PAMAM has strong fluorescence, and the dynamic track of drug carriers and the dynamic drug release process can be monitored by the AIE and FRET effects between H-PAMAM and DOX, respectively. Furthermore, the introduction of disulfide bonds and the pH sensitivity of H-PAMAM enable the achievement of rapid selective release of loaded DOX at the tumor while remaining stable under normal physiological conditions. In vitro cytotoxicity indicates that the drug-loaded supramolecular assembly has a good therapeutic effect on cancer. In addition, the H-PAMAM core is different from the traditional AIE functional group, which has no conjugated structure, such as a benzene ring, thereby providing better biocompatibility. This technology will have broad applications as a new drug delivery system.

Abstract
Stimuli-responsive polymeric nanostructures have emerged as potential drug carriers for cancer therapy. Herein, we synthesized redox-responsive diselenide bond containing amphiphilic polymer, Bi(mPEG-PLGA)-Se2 from mPEG-PLGA and 3,3'-diselanediyldipropanoic acid (DSeDPA) using DCC/DMAP as coupling agents. Due to its amphiphilic nature, Bi(mPEG-PLGA)-Se2 self-assembled in to stable micelles in aqueous solution with a hydrodynamic size of 123.9 ± 0.85 nm. The Bi(mPEG-PLGA)-Se2 micelles exhibited DOX-loading content (DLC) of 6.61 wt% and encapsulation efficiency (EE) of 54.9%. The DOX-loaded Bi(mPEG-PLGA)-Se2 micelles released 73.94% and 69.54% of their cargo within 72 h upon treatment with 6 mM GSH and 0.1% H2O2, respectively, at pH 7.4 and 37 °C. The MTT assay results demonstrated that Bi(mPEG-PLGA)-Se2 was devoid of any inherent toxicity and the DOX-loaded micelles showed pronounced antitumor activities against HeLa cells, 44.46% of cells were viable at maximum dose of 7.5 µg/mL. The cellular uptake experiment further confirmed the internalization of DOX-loaded Bi(mPEG-PLGA)-Se2 micelles and endowed redox stimuli triggered drug release in cytosol and nuclei of cancer cells. Overall, the results suggested that the smart, biocompatible Bi(mPEG-PLGA)-Se2 copolymer could serve as potential drug delivery biomaterial for the controlled release of hydrophobic drugs in cancer cells.

Abstract
The study of multifunctional polymer micelles combined with chemotherapy due to reduced systemic toxicity and enhanced efficacy has attracted intensive attention. Herein, a multifunctional core-cross-linked hybrid micelle system based on mPEG- b-PGu(BA-TPE) and OCT-PEG- b-PGu(DA-TPE) with pH- and redox-triggered drug release and aggregation-induced emission (AIE) active imaging has been developed for active targeting of neuroendocrine neoplasms (NENs), especially neuroendocrine carcinomas (NECs) with poor prognosis. These micelles showed excellent biocompatibility and stability. After the formation of borate ester bonds, core-cross-linked micelles (CCLMs) showed enhanced emission properties. In addition, etoposide (ETO), one of the most important anticancer drugs of NECs, was loaded into the hydrophobic core of micelles by self-assembly with an average diameter of 274.6 nm and spherical morphology. Octreotide (OCT) conjugated onto the micelles enhanced cellular uptake by receptor-mediated endocytosis. ETO-loaded micelles demonstrated the dual-responsive triggered intracellular drug release and great tumor suppression ability in vitro. Compared with free ETO, ETO-loaded CCLMs exhibited a considerable antitumor effect and significantly reduced side effects. Considering the active tumor targeting, dual-responsive drug release and the AIE effect, the polymer micelle system will be a potential candidate for diagnosis and oncotherapy of NENs.

Abstract
Fluorescence imaging is a promising visualization tool and possesses the advantages of in situ response and facile operation; thus, it is widely exploited for bioassays. However, traditional fluorophores suffer from concentration limits because they are always quenched when they aggregate, which impedes applications, especially for trace analysis and real-time monitoring. Recently, novel molecules with aggregation-induced emission (AIE) characteristics were developed to solve the problems encountered when using traditional organic dyes, because these new molecules exhibit weak or even no fluorescence when they are in free movement states but emit intensely upon the restriction of intramolecular motions. Inspired by the excellent performances of AIE molecules, a substantial number of AIE-based probes have been designed, synthesized, and applied to various fields to fulfill diverse detection tasks. According to numerous experiments, AIE probes are more practical than traditional fluorescent probes, especially when used in bioassays. To bridge bioimaging and materials engineering, this review provides a comprehensive understanding of the development of AIE bioprobes. It begins with a summary of mechanisms of the AIE phenomenon. Then, the strategies to realize accurate detection using AIE probes are discussed. In addition, typical examples of AIE-active materials applied in diagnosis, treatment, and nanocarrier tracking are presented. In addition, some challenges are put forward to inspire more ideas in the promising field of AIE-active materials.

Abstract
Gambogenic acid (GNA) has been demonstrated with outstanding antitumor activity as a potential antitumor drug in recent years. However, the low solubility and deficient bioavailability of GNA seriously hinder its practical application in the clinic area. In this study, a novel amphiphilic block copolymer, poly (acrylic acid)-b-polycaprolactone (PAA-b-PCL) is prepared and assembled into pH-responsive polymeric micelles (PMs) as one mold of drug delivery system (DDS) with unique properties. Relevant investigation on PMs exhibits excellent carrying potential and pH-dependent release performance for GNA. The drug loading capacity (DLC) and drug loading efficiency (DLE) for GNA-loaded PMs can be achieved as high as 15.20 ± 0.07% and 83.67 ± 0.49%, respectively. The in vitro experiments indicate that the GNA releasing time, cytotoxicity, and cellular uptake are significantly enhanced. Especially, the peak concentration (Cmax) and area under the curve (AUC) are promoted sharply in the GNA-loaded PMs concentration-time curve. This study not only provides a novel way to widen the application of anticancer GNA in the future, but also extends the potential of stimuli-responsive copolymers to biomedical applications.

Abstract
The objective of this study is to improve the overall prognosis of patients with hepatocellular carcinoma (HCC); therefore, new therapeutic methods that can be used in vivo are urgently needed. In this study, the relationship between the quantities of microRNA (miR)-125b-5p in clinical specimens and clinicopathological parameters is analyzed. A folate-conjugated nanocarrier is used to transfect miR-125b-5p in vivo and to observe the therapeutic effect on HCC. The inhibitory effect and mechanism of miR-125b-5p on hepatoma cells are also studied. Data from clinical specimens and in vitro experiments confirm that the miR-125b-5p quantity is negatively correlated with progression, and the target protein that regulates the epithelial-mesenchymal transition (EMT)/cancer stem cells (CSC) potential in HCC is STAT3. The miR-125b-5p/STAT3 axis inhibits the invasion, migration, and growth of HCC via inactivation of the wnt/β-Catenin pathway. miR-125b-5p-loaded nanomedicine effectively inhibits the EMT/CSC potential of hepatoma cells in vivo together with their magnetic resonance imaging (MRI) visualization characteristics. An HCC-therapeutic and MRI-visible nanomedicine platform that achieves noninvasive treatment effect monitoring and timely individualized treatment course adjustment is developed.

Abstract
Polymeric micelles with stimuli-triggered drug release and AIE active bioimaging have emerged as potential candidates for theranostics. Herein, a curcumin (Cur) loaded oxidation-responsive mPEG-b-PLG (Se)-TP polymeric micelle system with great aggregation-induced emission (AIE) active and two-photon imaging property has been developed for simultaneous antitumor treatment and bioimaging. Cur-loaded polymeric micelles with a core-shell structure and a homogeneous size of 136 nm show great physiological stability while rapidly disassemble under oxidation environment with accelerated drug release. The excellent biocompatibility and great AIE property and two-photon excitation endow these functional mPEG-b-PLG (Se)-TP micelles as bioprobes for the two-photon imaging of cells and deeper tissues. Furthermore, the biodistribution of nanocarriers and intracellular drug delivery can also be traced. Moreover, the Cur-loaded micelles also show great tumor inhibition ability and minimal side effects in vivo compared with free drug. These novel polymeric micelles are expected to be potential candidates for cancer theranostics.

Abstract
The vigorous development of nanotechnology has been accompanied by an equally strong interest and research efforts in nano-based drug delivery systems (NDDSs). However, only a few NDDSs have been translated into clinic thus far. One of the important hurdles is the lack of tools to comprehensively and directly trace the biological fate of NDDSs. Recently, aggregation-induced emission (AIE) fluorophores have emerged as attractive bioimaging tools due to flexible controllability, negligible toxicity and superior photostability. Herein, we recapitulate the current advances in the application of AIE fluorophores to monitor NDDSs both in vitro and in vivo. Particularly, we discuss the cellular fates of self-indicating and stimuli-responsive NDDSs with AIE fluorophores. Moreover, we highlight the in vivo application of AIE agents on the long-term tracking of therapeutics and the multi-modal monitoring of diagnostics in NDDSs. Challenges and opportunities in AIE-guided exploration of NDDSs are also discussed in detail.

Macromol Biosci 2019; 19:e1800478. [PMID: 30694599 DOI: 10.1002/mabi.201800478] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2018] [Revised: 01/15/2019] [Indexed: 12/15/2022]
Abstract
The use of natural compounds to construct biomaterials, including delivery system, is an attractive strategy. In the present study, through threading functional α-cyclodextrins onto the conjugated macromolecules of poly(ethylene glycol) (PEG) and natural compound bile acid, glycopolymers of polyrotaxanes with the active targeting ability are obtained. These glycopolymers self-assemble into micelles as evidenced by dynamic light scattering and transmission electron microscopy, in which glucosamine, as an example of targeting groups, is introduced. These micelles after loading doxorubicin (DOX) exhibit the selective recognition with cancer cells 4T1. Meanwhile, the maximal half inhibitory concentration is determined to be ≈2.5 mg L-1 for the DOX-loaded micelles, close to the value of free DOX·HCl (1.9 mg L-1 ). The cumulative release of DOX at pH 5.5 is faster than at pH 7.4, which may be used as the controlled release system. This drug delivery system assembled by glycopolymers features high drug loading of DOX, superior biocompatibility. The strategy not only utilizes the micellization induced by bile acids, but also overcomes the major limitation of PEG such as the lack of targeting groups. In particular, this drug delivery platform can extend to grafting the other targeting groups, rendering this system more versatile.

Abstract
In recent years, intelligent polymeric micelles with multifunctions are in urgent demand for cancer diagnosis and therapy. Herein, pH and redox dual-responsive prodrug micelles with aggregation-induced emission (AIE) active cellular imaging and charge conversion have been prepared for combined chemotherapy and bioimaging based on a novel doxorubicin-conjugated amphiphilic PMPC-PAEMA-P (TPE- co-HD)-ss-P (TPE- co-HD)-PAEMA-PMPC copolymer. The doxorubicin is conjugated via a pH cleavable imine linkage and can be packed in the hydrophobic core along with the glutathione (GSH)-sensitive disulfide bond. The DOX-conjugated inner core is sealed with a pH-responsive PAEMA as the "gate", which would rapidly open in the acidic condition, following the drug release and charge conversion-mediated acceleration of endocytosis. After an efficient internalization, the disulfide bond can be cleaved by the high concentration of GSH causing the further accelerated drug release. Meanwhile, intracellular drug delivery can be traced due to the AIE behavior of micelles. Moreover, great tumor inhibition in vitro and in vivo has been demonstrated for these DOX-conjugated micelles. This smart prodrug micelle system would be a desirable drug carrier for cancer therapy and bioimaging.
