Near-infrared (NIR) fluorescence imaging has been proved as an effective modality in identifying the tumor border and distinguishing the tumor cells from healthy tissue during the oncological surgery. Developing NIR fluorescent probes with high tumor to background (T/B) signal is essential for the complete debulking of the tumor, which will prolong the survival rate of tumor patients. However, the nonspecific binding and always-on properties of the conventional fluorescent probes leads to high background signals and poor specificity. Method: To address this problem, glutathione (GSH)-responsive, two disulfide-bonded dicyanine dyes (ss-diCy5 and ss-diNH800CW) were synthesized. As synthesized dyes are quenched under normal physiological conditions, however, once reached to the tumor site, these dyes are capable of emitting strong fluorescence signals primarily because of the cleavage of the disulfide bond in the tumor microenvironment with high GSH concentration. Besides, the GSH-responsive behavior of these dyes was monitored using the UV-vis and fluorescence spectroscopy. The diagnostic accuracy of the aforementioned dyes was also tested both in tumor cells and 4T1-bearing mice. Results: The fluorescence signal intensity of disulfide dicyanine dyes was quenched up to 89% compared to the mono cyanine dyes, thus providing a very low fluorescence background. However, when the disulfide dicyanine dye reaches the tumor site, the dicyanine is cleaved by GSH into two mono-dyes with high fluorescence strength, thus producing strong fluorescent signals upon excitation. The fluorescent signal of the dicyanine was enhanced by up to 27-fold after interacting with the GSH solution. In vivo xenografts tumor studies further revealed that the fluorescence signals of aforementioned dyes can be quickly recovered in the solid tumor. Conclusion: In summary, the disulfide dicyanines dyes can provide a promising platform for specific tumor-activatable fluorescence imaging with improved T/B value.

As a potential method for tumor treatment, tumor vaccine immunization induces a tumor-specific cellular immune response via immunization with tumor antigens. The delivery of exogenous antigen proteins into the cytoplasm of antigen-presenting cells is well known to induce an intensive cellular immune response for tumor treatment. In this work, we fluorinated a redox-responsive hyperbranched poly(amidoamine) (HPAA) with heptafluorobutyric anhydride to prepare a fluorinated HPAA (HPAA-F7) for use as a vaccine delivery system for antitumor therapy. The immunization results show that HPAA-F7 as a vaccine carrier could effectively promote the intracellular uptake and cytoplasmatic delivery of antigen proteins and induce potent antitumor cellular immunity. The novel vaccine carrier HPAA-F7 could be further developed for antitumor immunotherapy.

Lytic peptides have been demonstrated to exhibit obvious advantages in cancer therapy with binding ability toward tumor cells via electrostatic attractions, which are lack of active targeting and aggregation to tumor tissue. In the present study, five conjugated lytic peptides were redesigned and constructed to target gonadotropin releasing hormone receptors (GnRHr), meanwhile, the disulfide bridge was introduced to achieve redox sensitive delivery based on the experience from the preliminary work of lytic peptides P3 and P7. YX-1, was considered to be the most promising for in-depth study. YX-1 possessed high potency (IC50 = 3.16 +/- 0.3 mu M), low hemolytic effect, and cell membrane permeability in human A2780 ovarian cancer cells. Moreover, YX-1 had prominent pro-apoptotic activity by activating the mitochondria-cytochrome c-caspase apoptotic pathway. The study yielded the conjugate YX-1 with superior properties for antineoplastic activity, which makes it a promising potential candidate for targeting cancer therapy.

The quantification of proteins and peptides becomes more important besides mere identification in modern life sciences. Therefore, we have developed a new reagent that adds to the known metall-coded affinity tagging strategy employed in molecular and elemental mass spectrometry containing a photocleavable linker. A synthesis route was developed that provides the new reagent in good yields. The stability of the synthesized reagents was assessed under different temperature and illumination conditions. Labeling reactions were carried out at peptide and protein level, while also the fragmentation behavior of labeled peptides was assessed. In additional experiments, the photocleavability of the new reagent was examined. Upon irradiation with ultraviolet light, the photoproducts were liberated and could be used for quantification of labeled peptides.

Combined blockades of CTLA-4 and PD-1 can yield better overall complementary clinical outcomes than individual blockades, but the response rates are still relatively low. To investigate the anti-tumor effects of various combined strategies, we designed various spherical nucleotide nanoparticles (SNPs) loaded with CTLA-4 aptamer (cSNPs), PD-1 siRNA (pSNPs) or both (hybrid SNPs, or hSNPs). The results demonstrated that hSNPs could promote significantly stronger anti-tumor immune responses in a nonredundant fashion than the mixture of pSNPs and cSNPs (pSNPs & cSNPs). We reasoned that this is because all individual immune cells could receive both CTLA-4 and PD-1 blockades when they engulfed hSNPs, but it is much less likely that individual immune cells could receive both CTLA-4 and PD-1 blockades as many of them may not take both pSNPs and cSNPS from pSNPs & cSNPs. Further results revealed that the synergistic immune stimulatory effects of CTLA-4 and PD-1 blockades in the form of hSNPs were at least partly through regulating the immune suppressive function of both Tregs and TIM3(+)exhausted-like CD8 T cells and allowing effector T cells to expand. This mechanism is not identical to earlier reported mechanisms of CTLA-4 and PD-1 blockades.

The interaction of Pt(II) and Au(III) with disulfides (l-cystine, cystamine, dl-homocystine and 3,3?-dithiodipropionic acid) in hydrochloric acid aqueous solutions was studied. In the case of Pt(II), the oxidative addition reaction leads to formation of the Pt(IV) thiol complex. In the case of Au(III) disulfide, binding causes a reduction to Au(0) and oxidation of the disulfide to sulfonic acid. Cyclic voltammetry and different spectroscopic methods were used to study the process. The pattern of influence of the metallic properties for d(8) ions in the direction of the reaction was found.

Background: Recent data have suggested a substantial incidence of atrial arrhythmias (AAs) in cardiac sarcoidosis (CS). Our study aims were to first assess how often AAs are the presenting feature of previously undiagnosed CS. Second, we used prospective follow-up data from implanted devices to investigate AA incidence, burden, predictors, and response to immunosuppression. Methods and Results: This project is a substudy of the CHASM-CS (Cardiac Sarcoidosis Multicenter Prospective Cohort Study; NCT01477359). Inclusion criteria were presentation with clinically manifest cardiac sarcoidosis, treatment-naive status, and implanted with a device that reported accurate AA burden. Data were collected at each device interrogation visit for all patients and all potential episodes of AA were adjudicated. For each intervisit period, the total AA burden was obtained. A total of 33 patients met the inclusion criteria (aged 56.1 +/- 7.7 years, 45.5% women). Only 1 patient had important AAs as a part of the initial CS presentation. During a median follow-up of 49.1 months, 11 of 33 patients (33.3%) had device-detected AAs, and only 2 (6.1%) had a clinically significant AA burden. Both patients had reduced burden after CS was successfully treated and there was no residual fluorodeoxyglucose uptake on positron emission tomography scan. Conclusions: First, we found that AAs are a rare presenting feature of clinically manifest cardiac sarcoidosis. Second, AAs occurred in a minority of patients at follow-up; the burden was very low in most patients. Only 2 patients had clinically significant AA burden, and both had a reduction after CS was treated. REGISTRATION: URL: https://www.clinicaltrials.gov; unique identifier NCT01477359.

Multifunctional nanosystems that can transport therapeutic and diagnostic agents into tumor sites and activate their respective functions via tumor-microenvironment recognition are highly desirable for clinical applications. We fabricated pH and redox dual-activatable self-assembled nanotheranostics (named as DA-SNs) via coordination-driven self-assembly of chlorin e6 (Ce6) disulfide-linked pH sensitive polymer ligand, poly (isobutylene-alt-maleic anhydride-graft-methoxy-poly (ethyleneglycol)-graft-imidazole-graft-Cystamine-Ce6) [PIMA-mPEG-API-SS-Ce6], and gadolinium ions (Gd3+). DA-SNs exhibited uniform particle size of similar to 48 nm, excellent stability, and inherent biosafety. Negatively charged DA-SNs could prolong blood circulation time (t(1/2) = 2.91 h) and improve tumor accumulation. Moreover, DA-SNs could undergo surface charge switch from negative charge to positive one in a slightly acidic tumor extracellular environment (pH 6.8), thus enhancing cellular uptake. After entering tumor cells, fluorescence, photodynamic therapeutic activity, and T1MR contrast from DA-SNs could be activated within this intracellular environment with lowered pH and high level of GSH. Importantly, human tumors implanted in mice could be successfully visualized via distinct pH and redox dual-sensitive T1MR contrast and fluorescence imaging, indicating that DA-SNs could serve as a dual-modal MR/fluorescence imaging probe for tumor-targeting diagnosis. In addition, DA-SNs exhibited superior photodynamic therapeutic efficiency with negligible side effects. Therefore, this DA-SN shows great promise for synergistic photodynamic therapy and diagnostic imaging.

In this paper, a novel redox-responsive nanoparticles has been designed for targeted delivery of docetaxel (DTX). Chondroitin sulfate (CS) was used to construct the nanoparticles due to the ability of tumor targeting through binding with CD44 receptor that overexpresses on the surfaces of various tumor cells. A redox-responsive small-molecular DTX prodrug was prepared through modifying with cystamine containing disulfide bonds (Cys-DTX). Then the DTX prodrug was grafted to the CS to construct the amphiphilic polymer (CS-ss-DTX). Further, Cys-DTX/CS-ss-DTX nanoparticles were formed by self-assembly of amphiphilic polymer and incorporation of free Cys-DTX prodrug. This category of nanosized DTX delivery system was expected for not only exhibiting high permeability and cytotoxicity of Cys-DTX prodrug, but also targeting transportation of encapsulated redox-responsive Cys-DTX prodrug. According to results of related researches on physicochemical properties and biological evaluation, the novel redox-responsive Cys-DTX/CS-ss-DTX nanoparticles increased amount of DTX released from the nanoparticles in reductive environment, improved permeability in tumor tissues, enhanced cytotoxicity and decreased side effects compared with free DTX. All of these results showed that this kind of Cys-DTX/CS-ss-DTX nanoparticles were worthy of being expectation in tumor chemotherapy in future.

Glutathione (GSH) plays a vital role in maintaining biological redox homeostasis. Accordingly, accurate imaging of glutathione in vivo is of great significance. Herein, we propose a magnetic resonance energy transfer (MRET) strategy based on a distance-dependent magnetic exchange coupling effect (MECE), which can realize GSH detection within tumors in vivo by susceptibility weighted imaging (SWI). Fe3O4 nanoparticles (NPs) and CoFe2O4 NPs linked with cystamine (Fe3O4-S-S-CoFe2O4) have been successfully designed as SWI nanoprobes. After the disulfide bonds are broken by excess GSH in the tumor, the increase in the distance between Fe3O4 NPs and CoFe2O4 NPs will induce a decrease of MECE and magnetic susceptibility. As a result, the changes in the SWI signals are used for tumor GSH detection in vivo. Experimental results in vitro and in vivo demonstrate that the Fe3O4-S-S-CoFe2O4 SWI nanoprobe can sensitively detect concentrations of GSH in tumors. Hence, this strategy not only improves the sensitivity of the GSH response in SWI but also provides a powerful basis for the design of other responsive functional MRI nanoprobes.
