A water-soluble cyclophane dimer having two disulfide groups as a reduction-responsive cleavable bond as well as several acidic and basic functional groups as a pH-responsive ionizable group 1 was successfully synthesized. It was found that 1 showed pH-dependent guest-binding behavior. That is, 1 strongly bound an anionic guest, 6-p-toluidinonaphthalene-2-sulfonate (TNS) with binding constant (K/M-1) for 1:1 host-guest complexes of 9.6 x 10(4) M-1 at pH 3.8, which was larger than those at pH 7.4 and 10.7 (6.0 x 10(4) and 2.4 x 10(4) M-1, respectively), indicating a favorable electrostatic interaction between anionic guest and net cationic 1. What is more, release of the entrapped guest molecules by 1 was easily controlled by pH stimulus. Large favorable enthalpies (Delta H) for formation of host-guest complexes were obtained under the pH conditions employed, suggesting that electrostatic interaction between anionic TNS and 1 was the most important driving force for host-guest complexation. Such contributions of Delta H for formation of host-guest complexes decreased along with increased pH values from acidic to basic solutions. Upon addition of dithiothreitol (DTT) as a reducing reagent to an aqueous PBS buffer (pH 7.4) containing 1 and TNS, the fluorescence intensity originating from the bound guest molecules decreased gradually. A treatment of 1 with DTT gave 2, having less guest-binding affinity by the cleavage of disulfide bonds of 1. Consequently, almost all entrapped guest molecules by 1 were released from the host. Moreover, such reduction-responsive cleavage of 1 and release of bound guest molecules was performed more rapidly in aqueous buffer at pH 10.7.

Multidrug resistance (MDR) of cancer cells is a significant challenge in chemotherapy, highlighting the urgent medical need for simple and reproducible strategies to reverse this process. Here, we report the development of an active tumor-targeting and redox-responsive nanoplatform (PA-ss-NP) using hyaluronic acid-g-cystamine dihydrochloride-poly-epsilon-(benzyloxycarbonyl)-L-lysine (HA-ss-PLLZ) to co-deliver paclitaxel (PTX) and apatinib (APA) for effective reversal of MDR. This smart nanoplatform specifically bound to CD44 receptors, leading to selective accumulation at the tumor site and uptake by MCF-7/ADR cells. Under high concentrations of cellular glutathione (GSH), the nanocarrier was degraded rapidly with complete release of its encapsulated drugs. Released APA effectively inhibited the function of the P-glycoprotein (P-gp) drug pump and improved the sensitivity of MDR cells to chemotherapeutic agents, leading to the recovery of PTX chemosensitivity in MDR cells. As expected, this newly developed intelligent drug delivery system could effectively control MDR, both in vitro and in vivo.

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.

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.

Inhibition performance of 2,2′-diaminodiethyl disulfide (DA) was studied against mild steel (MS) corrosion in 0.5 M HCl. Electrochemical impedance spectroscopy (EIS), potentiodynamic (PD) polarization measurements were utilized to investigate the influence of inhibitor concentration and temperature on efficiency, as well as explanation of inhibition mechanism. Scanning electron microscopy (SEM) analysis was utilized to investigate the surface damages due to corrosion, in the absence and presence of inhibitor molecules. PD data revealed that the studied molecule exhibits mixed type inhibitor behavior on steel surface. Moreover, the calculated free adsorption energy (Delta G(ads)(o)) value is 38.45 kJ mol(-1), which indicates to strong adsorptive interaction by both physical and chemical means. UV-Visible study results supported the idea that there is strong interaction between the surface with the molecule, via its -S and -N atoms. As a consequence, 91.7% inhibition efficiency was determined in presence of 1.0 mM DA. (C) 2020 Elsevier B.V. All rights reserved.

Monoamino cyclic tellurides with a five-or six-membered ring structure and their derivatives were developed as a new class of catalyst for the oxidation of organothiols to organodisulfides in a glutathione peroxidase-like catalytic reaction. Quantitative conversion and high reaction rate were achieved by performing the reaction in an organic-aqueous segmented microflow system. Importantly, the process circumvented product purification, which is a major limitation of current organodisulfide synthetic methods.

Development of novel activable dual-mode T-1/T-2-weighted magnetic resonance (MR) contrast agents with the same composition for dynamic precision imaging of tumors has been a challenging task. Here, we demonstrated a strategy to prepare clustered Fe3O4 nanoparticles (NPs) with redox-responsiveness to tumor microenvironment to achieve switchable T-2/T-1-weighted dual-mode MR imaging applications. In this study, we first synthesized ultrasmall Fe3O4 NPs with an average size of 3.3 nm and an r, relaxivity of 4.3 mM(-1) s(-1), and then cross-linked the single Fe3O4 NPs using cystamine dihydrochloride (Cys) to form clustered Fe3O4/Cys NPs. The Fe3O4 nanoclusters (NCs) possess desirable colloidal stability, cytocompatibility, high r(2) relaxivity (26.4 mM(-1) s(-1)), and improved cellular uptake efficiency. Importantly, with the redox-responsiveness of the disulfide bond of Cys, the Fe3O4 NCs can be dissociated to form single particles under a reducing condition, hence displaying a switchable T-2/T-1-weighted MR imaging property that can be utilized for dynamic precision imaging of cancer cells in vitro and a subcutaneous tumor model in vivo due to the reductive intracellular environment of cancer cells and the tumor microenvironment. With the tumor reductive microenvironment-mediated switching of T-2 to T-1 MR effect and the ultrasmall size of the single particles that can pass through the kidney filter, the developed Fe3O4 NCs may be used as a promising switchable T-2/T-1 dual-mode MR contrast agent for precision imaging of different biosystems.

Tedious polymeric modifications, laborious syntheses, low water solubility, high cytotoxicity and low quantum yields are still the major concerns related to fluorescent materials used for biosensing applications. Here we report one-pot facile synthesis of polyethylene glycol (PEG)-modified cystamine-based multifunctional fluorescent dyes named as CPEG-168, CPEG-1000 and CPEG-2000, which can be used for biosensing and detection of both cations and anions in pure aqueous medium. Rapid response toward thiols could be achieved due to the presence of disulfide functionality and reversible redox property between thiol and disulfide. A cyclic structure is formed by (NH-H) intramolecular hydrogen bonding to produce electron dense region for strong fluorescence emission. The presence of -NH group made them sensitive toward Cu2+ ions, while excellent sensitivity toward pH and F- ions was provided by intramolecular hydrogen bonding between -NH groups. The increase in chain length of PEGs enhanced the fluorescence emission intensities due to the formation of more rigid structure, and hence, the desired quantum yields can be tuned by changing the chain length of PEG. The aforementioned properties along with high brightness in aqueous solution, at biological pH and temperature range, make these fluorescent dyes potential candidates for biosensing applications and detection of cations and anions.
