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.

We present a sensitive single step nanobiosensor for thyroid disease diagnosis. Nanoparticles modified screen printed carbon electrode catalyzes the formation of peptide bond between anti-TSH antibody and amino coated gold nanoparticles rendering a covalently coupled antibody. The nanobiosensor detects and quantifies the thyroid stimulating hormone in the sample by sensing the effective resistance offered by electrode. As the TSH concentration increases in serum sample, more is the immunocomplex formed and higher is the resistance offered by electrode. Gold nanoparticles functionalization with cystamine dihydrochloride facilitates a covalent bonding between surface amino group and carboxylic Fc ensuring maximizing available active antibody. This strategy ensures a much lower limit of detection in addition to improved detection range due to increased loading capacity as a result of larger effective surface area offered by gold nanoparticles. These two aspects of immunosensor fabrication resulted in limit of detection as low as 0.001 mu IU/mL and an enhanced detection range of 0.001-150 mu IU/mL. This makes the developed immunosensor suitable for diagnostic purpose covering the clinically relevant range and a simple detection technique makes it potential candidate for fabrication of a Point-of-Care device for detection of Thyroid dysfunctioning.

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.

Multidrug resistance (MDR) is a major reason for anticancer chemotherapy failure, and P-glycoprotein (P-gp) over-expressing on tumor cells is considered as the important target to overcome MDR. Emerging reports have showed that vitamin E (VE) can cause significant reversal of MDR due to inhibition of ATPase activity. Accordingly, we synthesized hyaluronic acid (HA) conjugated vitamin E succinate (VES) polymer, which can self-assemble into micelles and thus achieve high drug (paclitaxel (PTX) used as model drug) encapsulation as well as tumor accumulation owing to the enhanced permeability and retention (EPR) effect and HA active targeting ability. In addition, the linker between HA and VES utilized in this work was disulfide bond with reduction-sensitive property, which would respond to high glutathione (GSH) concentration in tumor cytoplasmic environment and trigger HA-CYS-VES polymer disassociation and drug release. In vitro, PTX loaded HA-CYS-VES demonstrated enhanced cytotoxicity, high apoptosis-inducing activities and reversal effects of PTX on MCF-7/Adr cells, compared to PTX. Also, cellular uptake and intracellular PTX accumulation tests displayed that PTX loaded HA-CYS-VES could more efficiently enter tumor cells and selectively release drug in cytosol so as to facilitate its function on microtubule. More importantly, PTX loaded HA-CYS-VES showed better tumor targeting ability, improved antitumor efficacy and low adverse effects on tumor-bearing mice. In conclusion, PTX loaded HA-CYS-VES exhibited a great potential for reversing MDR in anticancer chemotherapeutics.

Safety of 2,2′-Disulfanediyldiethanamine dihydrochloride. I found the field of Chemistry; Polymer Science very interesting.

Natural hydrogels are widely investigated for biomedical applications because of their structures similar to extracellular matrix of native tissues, possessing excellent biocompatibility and biodegradability. However, they are often susceptible to mechanical disruption. In this study, self-healing hyaluronic acid (HA) hydrogels are fabricated through a facile dynamic covalent Schiff base reaction. Dialdehyde-modified HA (AHA) precursor was synthesized, and then the AHA/cystamine dihydrochloride (AHA/Cys) hydrogels were formed by blending AHA and Cys at acidic pH levels. By varying Cys to AHA ratio, the hydrogel morphology, swelling and kinetics of gelation could be controlled. Gelation occurred fast, which was predominantly attributed to Schiff base reaction between the dialdehyde groups on AHA and amimo groups on Cys. The hydrogel exhibited improved mechanical properties with increase in Cys content. Furthermore, due to dynamic imine bonds, this hydrogel demonstrated excellent self-healing ability based on the stress after mechanical disruption. Also, it was found to be pH-responsive and injectable. Taken together, this kind of hyaluronic acid hydrogel can provide promising future for various biomedical applications in drug delivery, bioprinting, smart robots and tissue regeneration.

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, 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.

This study aimed to develop an efficient step-by-step osteosarcoma (OS)-targeting liposome system functionalized with a redox-cleavable, bone- and cluster of differentiation 44 (CD44)-dual-targeting polymer. Furthermore, the effect of coadministration of a tumor-penetrating peptide, internalizing RGD (iRGD), was investigated. First, a bone-targeting moiety, alendronate (ALN), was conjugated with hyaluronic acid (HA), a ligand for CD44. This ALN-HA conjugate was coupled with DSPE PEG(2000)-COOH through a bioreducible disulfide linker (-SS-) to obtain a functionalized lipid, ALN-HA-SS-L, to be postinserted into preformed liposomes loaded with doxorubicin (DOX). The roles of ALN, HA, and the redox sensitivity of the ALN-HA-SS-L liposomes (ALN-HA-SS-L-L) in the anti-OS effect were critically evaluated against various reference liposomal formulations (with only ALN, HA, or redox sensitivity). ALN-HA-SS-L-L displayed a zeta potential of -26.07 +/- 0.32 mV and selectively disassembled in the presence of a reducing agent, 10 mM glutathione, which can be found in cancer cells. cells. Compared to various reference liposomes, ALN-HA-SS-L-L/DOX had significantly higher cytotoxicity to human OS MG-63 cells alongside high and rapid cellular uptake. In the orthotopic OS nude mouse models, ALN-HA-SS-L-L/DOX showed remarkable tumor growth suppression and prolonged survival time. This result was further improved by the coadministration of iRGD. The antitumor effects of various liposomes were ranked in the same order as the degree of tumor biodistribution shown by in vivo/ex vivo imaging: ALN-HA-SS-L-L coadministered with iRGD > ALN-HA-SS-L-L > HA-SS-L-L > HA-L-L > PEG-L> free drug. ALN-HA-SS-L-L/DOX also reduced the cardiotoxicity of DOX and lung metastases. Overall, this study demonstrated that ALN-HA-SS-L-L/DOX, equipped with bone- and CD44-dual-targeting abilities and redox sensitivity, could be a promising OS-targeted therapy. The efficacy could also be augmented by coadministration of iRGD.

Active targeting and overcoming multi-drug resistance (MDR) can be some of the important attributes of targeted therapy for metastatic breast cancer (MBC) and triple-negative breast cancer (TNBC) treatment. In this study, we constructed a hyaluronic acid (HA)-decorated mixed nanomicelles-encapsulating chemotherapeutic agent paclitaxel (PTX) and P-glycoprotein inhibitor ritonavir (RTV). HA was conjugated to poly (lactide) co-(glycolide) (PLGA) polymer by disulfide bonds (HA-ss-PLGA). HA is a natural ligand for CD44 receptors overexpressed in breast cancer cells. Disulfide bonds undergo rapid reduction in the presence of glutathione, present in breast cancer cells. The addition of RTV can inhibit the P-gp and CYP3A4-mediated metabolism of PTX, thus aiding in reversing MDR and sensitizing the cells toward PTX. An in vitro uptake and cytotoxicity study in MBC MCF-7 and TNBC MDA-MB-231 cell lines demonstrated the effective uptake of the nanomicelles and drug PTX compared to non-neoplastic breast epithelium MCF-12A cells. Interestingly, in vitro potency determination showed a reduction in mitochondrial membrane potential and reactive oxygen species in breast cancer cell lines, indicating effective apoptosis of cancer cells. Thus, stimuli-sensitive nanomicelles along with HA targeting and RTV addition can effectively serve as a chemotherapeutic drug delivery agent for MBC and TNBC.
