Development and characterization of layer-by-layer coated liposomes with poly(L-lysine) and poly(L-glutamic acid) to increase their resistance in biological media was written by Hermal, Florence;Frisch, Benoit;Specht, Alexandre;Bourel-Bonnet, Line;Heurtault, Beatrice. And the article was included in International Journal of Pharmaceutics (Amsterdam, Netherlands) in 2020.SDS of cas: 3326-34-9 This article mentions the following:

Multilayered coated liposomes were prepared using the layer-by-layer (LbL) technique in an effort to improve their stability in biol. media. The formulation strategy was based on the alternate deposition of two biocompatible and biodegradable polyelectrolytes – poly(L-lysine) (PLL) and poly(L-glutamic acid) (PGA) – on neg. charged small unilamellar vesicles (SUVs). Some parameters of the formulation process were optimized such as the polyelectrolyte concentration and the purification procedure. This optimized procedure has allowed the development of very homogeneous formulations of liposomes coated with up to 6 layers of polymers (so-called layersomes). The coating was characterized by dynamic light scattering (DLS), zeta potential measurements and Forster resonance energy transfer (FRET) between two fluorescently labeled polyelectrolytes. Studies on the stability of the formulations at 4°C in a buffered solution have shown that most structures are stable over 1 mo without impacting their encapsulation capacity. In addition, fluorophore release experiments have demonstrated a better resistance of the layersomes in the presence of a non-ionic detergent (Triton X-100) as well as in the presence of phospholipase A2 and human plasma. In conclusion, new multilayered liposomes have been developed to increase the stability of conventional liposomes in biol. environments. In the experiment, the researchers used many compounds, for example, 5-Amino-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 3326-34-9SDS of cas: 3326-34-9).

The role of ROS generation from magnetic nanoparticles in an alternating magnetic field on cytotoxicity was written by Wydra, Robert J.;Rychahou, Piotr G.;Evers, B.

And the article was included in Acta Biomaterialia in 2015.Name: 5-Amino-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one This article mentions the following:

Monosaccharide coated iron oxide nanoparticles were developed to selectively target colon cancer cell lines for magnetically mediated energy delivery therapy. The nanoparticles were prepared using a coupling reaction to attach the glucose functional group to the iron oxide core, and functionality was confirmed with physicochem. characterization techniques. The targeted nanoparticles were internalized into CT26 cells at a greater extent than non-targeted nanoparticles, and the nanoparticles were shown to be localized within lysosomes. Cells with internalized nanoparticles were exposed to an AMF to determine the potential to delivery therapy. Cellular ROS generation and apoptotic cell death was enhanced with field exposure. The nanoparticle coatings inhibit the Fenton-like surface generation of ROS suggesting a thermal or mech. effect is more likely the source of the intracellular effect, unless the nanoparticle coating is unstable in the cellular environment. This is the first study to assess glucose coated MNPs for the delivery of MagMED therapy. With exposure of an AMF, the glucose-coated nanoparticles displayed a significant increase in cellular ROS and apoptotic cell death with no measurable increase in media temperature To determine the mechanism of toxicity, we investigated the surface generation of ROS through Fenton-like chem. The coated systems displayed negligible ROS generation compared to uncoated nanoparticles. These observations suggest the cellular ROS measured is attributed to a thermal or mech. effect of the internalized nanoparticles. In summary, this manuscript reports on some new insights as to the mechanism of MagMED therapies, which are of high interest to the biomaterials and cancer nanomedicine fields.

Trehalose, a non-reducing disaccharide of glucose, is a natural bioactive and non-toxic sugar. It is found in many organisms that synthesize it when their cells are exposed to stress conditions. While not produced by mammalian cells, this disaccharide and also some of its derivatives have been shown to have a number of interesting properties that indicate their importance in the treatment of certain human diseases.

Determination of fructose 1,6-bisphosphate using a double-receptor sandwich type fluorescence sensing method based on uranyl-salophen complexes was written by Zhang, Guangliang;Liao, Lifu;Lin, Yingwu;Yang, Miao;Xiao, Xilin;Nie, Changming.

In this paper, we report a double-receptor sandwich type fluorescence sensing method for the determination of fructose bisphosphates (FBPs) using fructose 1,6-bisphosphate (F-1,6-BP) as a model analyte based on uranyl-salophen complexes. The solid phase receptor is an immobilized uranyl-salophen (IUS) complex which is bound on the surface of glass slides by covalent bonds. The labeled receptor is another uranyl-salophen complex containing a fluorescence group, or uranyl-salophen-fluorescein (USF). In the procedure of determining F-1,6-BP in sample solution, F-1,6-BP is first adsorbed on the surface of the glass slide through the coordination reaction of F-1,6-BP with IUS. It then binds USF through another coordination reaction to form a sandwich-type structure of IUS-F-1,6-BP-USF. The amount of F-1,6-BP is detected by the determination of the fluorescence intensity of IUS-F-1,6-BP-USF bound on the glass slide. Under optimal conditions, the linear range for the detection of F-1,6-BP is 0.05-5.0 nmol mL-1 with a detection limit of 0.027 nmol mL-1. The proposed method has been successfully applied for the determination of F-1,6-BP in real samples with satisfactory results.

Development of a highly sensitive fluorescence probe for peptidyl arginine deiminase (PAD) activity was written by Kunieda, Kazuki;Kawaguchi, Mitsuyasu;Ieda, Naoya;Nakagawa, Hidehiko. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2019.Recommanded Product: 3326-34-9 This article mentions the following:

Peptidyl arginine deiminases (PADs) catalyze the post-translational deimination of arginine residues to citrulline residues. Aberrant levels of PAD activity are associated with various diseases, such as rheumatoid arthritis, Alzheimer’s disease, and multiple sclerosis, so there is a need for simple and convenient high-throughput screening systems to discover PAD inhibitors as candidate therapeutic agents. Here, we report a highly sensitive off/on-type fluorescence probe for PAD activity based on the donor-excited photoinduced electron transfer (d-PeT) mechanism, utilizing the specific cycloaddition reaction between the benzil group of the probe and the ureido group of the PAD product, citrulline, under acidic conditions. We synthesized and functionally evaluated a series of probes bearing substituents on the benzil Ph group, and found that 4MEBz-FluME could successfully detect citrulline with higher sensitivity and broader dynamic range than our previously reported fluorescence probe, FGME. Moreover, we succeeded in establishing multiple assay systems for PAD subtypes activities, including PAD2 and PAD4, with 4MeBz-FluME thanks to its high sensitivity. We expect that our fluorescence probes will become a powerful tool for discovering PAD inhibitors of several subtypes. Thus, it should be suitable for high-throughput screening of chem. libraries for inhibitors of PADs.

The four-step dissociation of two fluorescein dyes bearing the amino group in 4′- and 5′-positions of the phthalic moiety was studied in water. The constants describing the equilibrium H4R2+⇌H3R+ ⇌ H2R ⇌ HR- ⇌ R2- were determined using the spectrophotometric method, at 25 °. In water, four steps of aminofluoresceins dissociation occur within pH range of 0-9. On going to 50 mass % aqueous ethanol, the increase in the pKa1, pKa2 and decrease in the pKa0, pKa(-1) values take place. The visible absorption spectra, referring to all the ionic (mol.) forms, were singled out. On the whole, the behavior of 4′-aminofluorescein is closer to that of the mother compound The shift of the equilibrium on introducing 50 mass % ethanol into the aqueous solution allowed better understanding the detailed scheme of prototropic equilibrium The tautomeric equilibrium of the mols. shifts toward the colorless lactone. This effect is expressed stronger for the 5′-aminofluorescein. For this dye, even signs of such tautomers of the single-charged anion as anion-lactone and phenolate anion are observed in aqueous ethanol, which are atypical for fluorescein in water-based solvents.

The aim of the present contribution is to prepare a functionalized bioactive glass potentially useful as prosthetic material, but also able to release organic mols. in response to a change of the pH environment. By this approach it is possible to develop devices which can be used for a triggered drug release in response to specific stimuli; this is an attractive research field, in order to avoid either systemic and/or local toxic effects of drugs. In particular, in the present paper we report data related to the development of a new formulation of bioactive glasses, their functionalization with organic mols. to obtain a pH-sensitive bond, their physicochem. characterization and in vitro bioactivity in simulated biol. fluids (SBF), and organic mol. delivery tests at different pH. The glass functionalization, by means of a covalent reaction, allows us to produce a model of pH-responsive bioactive biomaterial: when it is exposed to specific pH changes, it can favor the release of the organic mols. directly at the target site. Cysteamine and 5-aminofluorescein are used as model mols. to simulate a drug. The materials, before and after the different functionalization steps and in vitro release tests at different pH, have been characterized by means of different exptl. techniques such as X-ray powder diffraction (XRPD), Raman, FTIR and fluorescence spectroscopies, N2 adsorption, thermogravimetric (TGA) and elemental anal.
