Abstract
Thermogelling polymers with transparency, structure stability and biocompatibility are promising for biomedicine application. In this study, a thermogelling polymer P-C5PEG with tunable transparency was developed by the reaction between alternating copolymer C5PEG and chemically modified biomolecule Alg-PBA via boronic ester bonds. The sol-to-gel transition of P-C5PEG aqueous solution sensitively responded to changes in temperature, and the critical value could be adjusted between 15 and 40 °C by varying the content of C5PEG and Alg-PBA. As the weight ratio of Alg-PBA to C5PEG was over 0.3, the transparency of as-synthesized hydrogel kept above 75 % at 37 °C. Meanwhile, immersion P-C5PEG hydrogel in CaCl2 solution significantly increased its mechanical strength by 3 times due to chelation effect. The shear-resistance and self-healing properties were ensured by dynamic boronic ester bonds due to the protective effect of hydrophobic gel network. As a drug delivery, P-C5PEG hydrogel had a swelling rate of 3748.7 ± 103 % in PBS and could continuously release fluorescein sodium within 24 h. Moreover, the in vitro degradability and cytotoxicity of P-C5PEG was confirmed. Finally, the mechanisms behind the thermogelling property and tunable transparency were revealed. Overall, this thermogelling P-C5PEG polymer, with tunable transparency and thermo-responsiveness, exhibits great potential for biomedicine application.

Abstract
The controlled release of antioxidant substances at the intestinal oxidative damage site is crucial for alleviating intestine-related diseases. Herein, the novel ROS-responsive carrier was synthesized through simple amidation reaction between carboxymethyl chitosan (CMC) and methionine (Met), a natural organic compound containing ROS-responsive linkages (thioether). Initially, astaxanthin (AXT) nanoparticles (AXT2@CMT) with excellent stability and drug loading capacity (39.68 ± 0.23 μg/mL) were prepared by optimizing various reaction conditions. In the simulated high-concentration ROS environment of the intestine, CMT achieved a transition from hydrophobic groups (thioether) into hydrophilic groups (sulfone), which was conducive to the controlled release of AXT. In vitro cell experiments revealed that AXT2@CMT could effectively alleviate the oxidative damage in intestinal epithelioid cell line No. 6 (IEC-6 cell) caused by H2O2. This study achieved a straightforward preparation of ROS-responsive nanocarrier through food ingredients, offering a theoretical foundation for the controlled release of AXT at the intestinal oxidative damage site.

Bioact Mater 2023; 25:189-200.

Abstract
The combination of chemotherapy and photodynamic therapy (PDT) based on nanoparticles (NPs) has been extensively developed to improve the therapeutic effect and decrease the systemic toxicity of current treatments. However, overexpressed glutathione (GSH) in tumor cells efficiently scavenges singlet oxygens (1O2) generated from photosensitizers and results in the unsatisfactory efficacy of PDT. To address this obstacle, here we design H2O2-responsive polymer prodrug NPs with GSH-scavenger (Ce6@P(EG-a-CPBE) NPs) for chemo-photodynamic synergistic cancer therapy. They are constructed by the co-self-assembly of photosensitizer chlorin e6 (Ce6) and amphiphilic polymer prodrug P(EG-a-CPBE), which is synthesized from a hydrophilic alternating copolymer P(EG-a-PD) by conjugating hydrophobic anticancer drug chlorambucil (CB) via an H2O2-cleavable linker 4-(hydroxymethyl)phenylboronic acid (PBA). Ce6@P(EG-a-CPBE) NPs can efficiently prevent premature drug leakage in blood circulation because of the high stability of the PBA linker under the physiological environment and facilitate the delivery of Ce6 and CB to the tumor site after intravenous injection. Upon internalization of Ce6@P(EG-a-CPBE) NPs by tumor cells, PBA is cleaved rapidly triggered by endogenous H2O2 to release CB and Ce6. Ce6 can effectively generate abundant 1O2 under 660 nm light irradiation to synergistically kill cancer cells with CB. Concurrently, PBA can be transformed into a GSH-scavenger (quinine methide, QM) under intracellular H2O2 and prevent the depletion of 1O2, which induces the cooperatively strong oxidative stress and enhanced cancer cell apoptosis. Collectively, such H2O2-responsive polymer prodrug NPs loaded with photosensitizer provide a feasible approach to enhance chemo-photodynamic synergistic cancer treatment.

Abstract
Reactive oxygen species (ROS) play a key role in several biological functions of living organisms such as regulation of cell signalling, production of some hormones, modulation of protein function or mediation of inflammation. In this regard, ROS responsive polymers are ideal candidates for the development of stimuli-responsive biomaterials for target therapies. Among different ROS-responsive polymers, those containing thioether groups are widely investigated in the biomedical field due to their hydrophobic to hydrophilic phase transition under oxidative conditions. This feature makes them able to self-assemble in aqueous solutions forming micellar-type nanoparticles or hydrogels to be mainly used as drug carriers for local therapies in damaged body areas characterized by high ROS production. This review article collects the main findings about the synthesis of thioether-based ROS responsive polymers and polypeptides, their self-assembly properties and ROS responsive behaviour for use as injectable nanoparticles or hydrogels. Afterward, the foremost applications of the thioether-based ROS responsive nanoparticles and hydrogels in the biomedical field, where cancer therapies are a key objective, will be discussed.

Abstract
Stimuli-responsive drug delivery systems (DDSs) based on amphiphilic polymers have attracted much attention. In this study, we reported an innovative H2O2-responsive amphiphilic polymer (TBP), bearing a H2O2-sensitive phenylboronic ester, AIE fluorophore tetraphenylethene (TPE) hydrophobic, and polyethylene glycol hydrophilic (PEG) moieties. TBP could self-assemble into micelles with an encapsulation efficiency as high as 74.9% for doxorubicin (DOX) in aqueous solution. In the presence of H2O2, TBP micelles was decomposed by oxidation, hydrolysis and rearrangement, leading to almost 80% DOX release from TBP@DOX micelles. TBP and the corresponding degradation products were biocompatible, while TBP@DOX micelles only displayed obvious toxicity toward cancer cells. Drug delivery process was clearly monitored by confocal laser scanning microscopic (CLSM) and flow cytometry (FCM) analysis. Moreover, in vivo anticancer study showed that TBP@DOX micelles were accumulated in tumor region of nude mice and effectively inhibited tumor growth. The results suggested that the reported H2O2-responsive amphiphilic polymer displayed great potential in drug delivery and tumor therapy.

Abstract
A synthetic route for oxidation-sensitive core-multishell (osCMS) nanocarriers was established, and their drug loading and release properties were analyzed based on their structural variations. The nanocarriers showed a drug loading of 0.3-3 wt % for the anti-inflammatory drugs rapamycin and dexamethasone and the photosensitizer meso-tetra-hydroxyphenyl-porphyrin (mTHPP). Oxidative processes of the nanocarriers were probed in vitro by hydrogen peroxide, and the degradation products were identified by infrared spectroscopy supported by ab initio calculations, yielding mechanistic details on the chemical changes occurring in redox-sensitive nanocarriers. Oxidation-triggered drug release of the model drug Nile Red measured and assessed by time-dependent fluorescence spectroscopy showed a release of up to 80% within 24 h. The drug delivery capacity of the new osCMS nanocarriers was tested in ex vivo human skin with and without pretreatments to induce local oxidative stress. It was found that the delivery of mTHPP was selectively enhanced in skin under oxidative stress. The number and position of the thioether groups influenced the physicochemical as well as drug delivery properties of the carriers.

Abstract
Reactive oxygen species (ROS) play an essential role in regulating various physiological functions of living organisms; however, as the concentration of ROS increases in the area of a lesion, this may undermine cellular homeostasis, leading to a series of diseases. Using cell-product species as triggers for targeted regulation of polymer structures and activity represents a promising approach for the treatment. ROS-responsive polymer carriers allow the targeted delivery of drugs, reduce toxicity and side effects on normal cells, and control the release of drugs, which are all advantages compared with traditional small-molecule chemotherapy agents. These formulations have attracted great interest due to their potential applications in biomedicine. In this review, recent progresses on ROS responsive polymer carriers are summarized, with a focus on the chemical mechanism of ROS-responsive polymers and the design of molecular structures for targeted drug delivery and controlled drug release. Meanwhile, we discuss the challenges and future prospects of its applications.

Abstract
In order to maximize the therapeutic effect and and minimize the systemtic side effect of the small molecule anticancer drugs, biodegradable drug delivery systems (DDSs) that respond to tumor microenvironment (TME) have attracted significant attention. Herein, a novel redox/pH dual-responsive and biodegradable polyphosphazene (PPZ) nano-prodrugs have been prepared via one-pot crosslinking of vanillin modified DOX (VMD, acid-sensitive) and 4,4'-dihydroxydiphenyl disulfide (HPS, GSH-responsive) with hexachlorocyclotriphosphazene (HCCP). The phenol groups of the as-synthesized VMD and HPS have high nucleophilic substitution activity towards HCCP under base catalyst and afforded PPZ nano-prodrugs, denoted as HCCP-VMD-HPS, with a high drug loading ratio of up to 56.4 %. As expected, the skeleton of the PPZ consisting of imine bonds in VMD and the disulfide bonds in HPS and cyclotriphosphazenes inclined to be decomposed in low pH conditions and high level of GSH environments. The antitumor drug DOX was found to be controlled released in TME conditions (extracellular, pH∼6.8 and endosomes, lysosomes pH∼5.0 with ∼10 mM GSH), rather than neutral physiological conditions (pH 7.4 with ∼20 μM GSH). Moreover, the resulting HCCP-VMD-HPS nano-prodrug have obvious cytotoxicity to cancer cells while a negligible side effect to normal cells. We therefore believe that the prepared redox/pH dual-responsive and biodegradable PPZ DDSs have great potential in various field.

Abstract
With the utilization of high concentration reactive oxygen species (ROS) in tumor microenvironment, PEG-doxorubicin (PEG-DOX) prodrug was synthesized via a thioketal moiety as the linker, which was ROS cleavable to trigger DOX release from the self-assembled prodrug nanoparticles. The in vitro ROS sensitivity of prodrug nanoparticles (NPs) was investigated in Fenton agent and H2O2, and the disassembly of NPs was more sensitive to Fenton reagent. After internalized in HepG2 cells via endocytosis, the cellular ROS consuming test revealed intracellular DOX release. The pharmacokinetics and biodistribution study demonstrated that the in vivo elimination of NPs was significantly improved and the NPs were passively targeted to tumor tissues via EPR effect. The ROS-responsive prodrug NPs exhibited excellent antitumor activity in HepG2 tumor-bearing nude mice, remarkably induced tumor cells apoptosis and reduced the systemic toxicity of DOX. Our study revealed the ROS responsive prodrug nanoparticle is an effective strategy to fabricate nanomedicine for cancer chemotherapy.

Abstract
Due to no specific symptoms and lack of early diagnosis for ovarian cancer, most diagnosed patients are often in the terminal stage resulting that tumor tissue is unable to be resected completely by operation. So postoperative chemotherapy has become an important and indispensable treatment procedure for them. Up to date, it remains a challenge to treat ovarian cancer by an effective chemotherapy strategy. Recently, the strategy of ADDC has been regarded as a highly effective chemotherapy strategy to treat various cancers without any drug carriers. Here a novel ADDC is synthesized by linking a water-soluble antitumor drug floxuridine (Fud) and a water-insoluble antitumor drug chlorambucil (Cb) through the esterification. Then the Fud-Cb conjugate can form stable nanodrugs in water with an average size around 103.0 nm through molecular self-assembly. After internalization of cells, the ester bonds in nanodrugs can be degraded to release free Fud and Cb at a fixed ratio under the intracellular acid conditions, which exhibits the high synergistic effect on ovarian cancer cells. The cytotoxicity test results show that Fud-Cb nanodrugs can efficiently inhibit the growth of ovarian cancer cells. The apoptosis data exhibit that the cell necrotic and apoptotic rate treated with Fud-Cb nanodrugs is about 73.7 % and 18.76 % within 24 h. These results suggest that Fud-Cb nanodrugs based on ADDC strategy can effectively enhance synergistic anticancer efficacy to ovarian cancer.
