Chemically crosslinked recyclable photodeformable azobenzene (azo) polymer actuators with good stability (toward organic solvents and higher temperatures) and high processability and reconstruction ability hold great promise in many applications, but their development remains a challenging task. Herein, we report on for the first time a facile and highly efficient post-crosslinking method for addressing this issue. It involves first the synthesis of side-chain polymers bearing N-hydroxysuccinimide (NHS) carboxylate-substituted azo mesogens, fabrication of uniaxially oriented fibers from these azo polymers by the simple melt spinning method, and their subsequent post-crosslinking with cystamine (a diamine containing a disulfide bond) under mild conditions. The resulting chemically crosslinked fibers not only showed rapid and reversible photoinduced bending and unbending at ambient temperature as well as high mechanical strength and good solvent/heating stability, but also could be easily recycled into processable azo polymers in the presence of a reducing agent that can cleave the disulfide bond into thiol groups (i.e., tributylphosphine). In particular, the occurrence of the post-crosslinking reaction only on the thin surface layers of the azo polymer fibers afforded recycled polymers with large amounts of NHS carboxylate-substituted azo mesogens (together with a small amount of oxygen/heating-sensitive thiolsubstituted ones) in the first several (at least 5) recycling processes, thus allowing highly efficient reconstruction of photodeformable fibers with excellent photomobile properties by applying melt spinning and post-cross-linking (by using cystamine) methods. The strategy presented here opens the new possibility to the facile and efficient development of various advanced chemically crosslinked recyclable photodriven actuators.

I found the field of Polymer Science very interesting. Saw the article Dual-Responsive Cross-Linked Micelles from Amphiphilic Four-Arm Star Copolymers with Different Block Ratios for Triggering DOX Release published in 2020.0. Computed Properties of C4H14Cl2N2S2, Reprint Addresses Lin, WJ; Yi, GB (corresponding author), Guangdong Univ Technol, Sch Chem Engn & Light Ind, Guangzhou 510006, Peoples R China.. The CAS is 56-17-7. Through research, I have a further understanding and discovery of 2,2′-Disulfanediyldiethanamine dihydrochloride

The four-arm star copolymers poly(methacrylic acid)-poly(2-hydroxyethyl methacrylate-disulfide similar to)-poly(poly(ethylene glycol) methyl ether methacrylate) (4AS-PMAA(x)-(PHEMA-SS similar to)(y)-PPEGMA(z)) with four different block ratios were synthesized and could self-assembled into cross-linked polymer micelles for the exploration of the structure-property relationship. The cross-linked polymer micelles in aqueous solution had low critical micelle concentration (CMC) values (1.9-4.6 mg/L), which exhibited better stability than non-cross-linked micelles. The CMC value decreased with the increase of the length of inner PMAA core and hydrophobic PHEMA cross-linked middle layer. The blank and doxorubicin (DOX)-loaded micelles with different block ratios were prepared by dialysis with the particle sizes of 120-240 nm. The longer inner PMAA core and cross-linked middle layer enhanced the drug loading content (DLC) results and led to relatively bigger particle sizes of polymer micelles. The in vitro DOX release data revealed that DOX-loaded micelles had low DOX cumulative release percentages of 18-37% after 110 h at pH 7.4, but up to 83-90% when introducing reductant GSH at pH 5.0. The 4AS-PMAA(21.2)-(PHEMASS approximate to)(13.1)-PPEGMA(5.1) micelles with the longest PMAA core had the largest cumulative release of 90.1%. The DOX release process and mechanism of the micelles at different conditions fitted well with the semi-empirical equation. Overall, the results demonstrated that the block ratios and pH/redox-responsiveness of these four-arm star copolymers could be well-controlled and their self-assembled cross-linked micelles as anticancer drug carrier system could be improved by optimizing the different ratios.

Galectin-3 (gal-3) plays a crucial role in various cellular events associated to tumor metastasis and progression. In this direction, gal-3 binding core-shell glyconanoparticles based on citrus pectin (CP) have been designed for targeted, trigger-responsive combination drug delivery. Depolymerization via periodate oxidation in heterogeneous medium yielded low-molecular weight dialdehyde oligomers (CPDA) of CP with a gal-3 binding property (K-d = 160.90 mu M). CPDA-based core-shell nanoparticles prepared to enhance the gal-3 binding specificity via a multivalent ligand presentation have shown to reduce homotypic cellular aggregation, tumor cell binding with endothelial cells, and endothelial tube formation, the major steps involved in the progression of cancer. Immune-fluorescence and flow cytometric analysis confirmed significant reduction in gal-3 expression on MDA-MB 231 cancer cells upon incubation with nanoparticles. An on-demand tumor microenvironment-responsive release of drugs at low pH and high concentrations of glucose and glutathione prevailing in tumor milieu was achieved by introducing a cleavable Schiff’s base, a boronate ester, and disulfide linkages within the shell of the nanoparticles. Nanoparticles with encapsulated sulindac in the core and doxorubicin (DOX) in the shell demonstrated target specificity and enhanced internalization with synergistic cytotoxic effects with a 30-fold reduction in IC50 in DOX-resistant, triple-negative MDA-MB 231 breast cancer cells. Nanoparticles were radiolabeled with 131I radioisotopes with >= 80% efficiency while retaining its gal-3 binding property. Biodistribution studies of radiolabeled placebo nanoparticles and drug-loaded CPDA nanoparticles demonstrated proof of concept of gal-3 targeting seen as preferential accumulation in the gal-3-expressing tissues of the gastric tract. The CPDA core-shell nanoparticles are thus promising platforms for gal-3 targeting and inhibition of gal-3-mediated processes involved in cancer progression with a potential of radiolabeling for in vivo monitoring or delivering therapeutic doses of radiation and on-demand triggered, target-specific drug release.

Novel nanoparticle drug conjugates (NDCs) containing diverse, clinically relevant anticancer drug payloads (docetaxel, cabazitaxel, and gemcitabine) were successfully generated and tested in drug discovery studies. The NDCs utilized structurally varied linkers that attached the drug payloads to a beta-cyclodextrin-PEG copolymer to form self-assembled nanoparticles. In vitro release studies revealed a diversity of release rates driven by linker structure activity relationships (SARs). Improved in vivo pharmacokinetics (PK) for the cabazitaxel (CBTX) NDCs with glycinate-containing (1c) and hexanoate-containing linkers (2c) were demonstrated, along with high and sustained tumor levels (>168 h of released drug in tumor tissues). This led to potent efficacy and survival in both taxane- and docetaxel-resistant in vivo anticancer mouse efficacy models. Overall, the CBTX-hexanoate NDC 2c (CRLX522), demonstrated optimal and improved in vivo PK (plasma and tumor) and efficacy profile versus those of the parent drug, and the results support the potential therapeutic use of CRLX522 as a new anticancer agent.

Cevik, E in [Cevik, Emre] Imam Abdulrahman Bin Faisal Univ, IRMC, Dept Genet Res, POB 1982, Dammam 31441, Saudi Arabia published High Sensitive Detection of Prostate Specific Antigen by Using Ferrocene Cored Asymmetric PAMAM Dendrimer Interface Screen Printed Electrodes in 2019.0, Cited 43.0. Name: 2,2′-Disulfanediyldiethanamine dihydrochloride. The Name is 2,2′-Disulfanediyldiethanamine dihydrochloride. Through research, I have a further understanding and discovery of 56-17-7.

In this study, electrochemical immunosensors were developed for the detection of prostate specific antigen (PSA) using ferrocene (Fc) and polyamidoamine dendrimer (PAMAM) constructs. The biosensor fabrication was designed by modifying the screen-printed gold electrode (Au) with ferrocene cored dendrimers (FcPAMAM) synthesized in three different generations. The self-assembled monolayer principle was followed, to obtain sensitive, selective and disposable electrodes. Therefore, the Au electrodes were modified with cysteamine (Cys) to obtain a functional surface for FcPAMAM dendrimers to bind. Dendrimer generations were attached to this surface using a cross-linker (glutaraldehyde) so that a suitable surface was obtained for binding of biological components. The Monoclonal PSA antibody (anti-PSA) was immobilized on the Au electrode surface which coated with dendrimer, and (Au/Cys/FcPAMAM/anti-PSA) biosensing electrode was obtained. The PSA detection performances of electrochemical impedance spectroscopy (EIS) and Amperometry based immunosensors exhibited very low detection limits; 0.001 ng mL(-1) and 0.1 pg mL(-1), respectively. In addition, EIS and Amperometry based biosensors using Au/Cys/FcPAMAM/anti-PSA sensing electrode were represented excellent linear ranges of 0.01 ng mL(-1) to 100 ng mL(-1) and 0.001 ng mL(-1) to 100 ng mL(-1). In order to determine the applicability recovery and selectivity tests were performed using three different proteins in human serum.
