de Jesus, Jany H. F. published the artcileTHERMOANALYTICAL STUDIES ON NEW POLYMORPHIC FORMS OF PROPYL, OCTYL AND DODECYL GALLATES, HPLC of Formula: 121-79-9, the publication is Thermochimica Acta (2022), 179114, database is CAplus.

The thermal behavior of Pr (PG), octyl (OG) and dodecyl (DG) gallates, three antioxidants widely used in fuel and food industries, was evaluated by thermoanal. techniques (TG, DTA, DSC and hot stage microscopy), and complementary techniques, such as FTIR-ATR and XRD. All of them presented melting in characteristic temperatures during heating. The resulting liquid phases crystallized in different solid forms when cooled just after melting. However, when the samples were heated beyond melting temperature, they decomposed Although thermal studies were conducted at higher temperature than those in which they are regularly used, this work provided relevant information regarding their thermal behavior at higher temperatures Data from XRD, FTIR-ATR and hot stage microscopy were used to confirm the presence of new polymorphs. Finally, based on these results mechanisms describing the thermal behavior of PG, OG and DG were proposed.

Lupo, Cristina published the artcileA microcalorimetric and microscopic strategy to assess the interaction between dietary fibers and small molecules, Related Products of esters-buliding-blocks, the publication is Carbohydrate Polymers (2022), 119229, database is CAplus and MEDLINE.

The interaction between small mols. and neutral soluble dietary fiber is one of the proposed mechanisms determining the bioavailability of these components in the small intestine. However, the weak nature of these interactions makes it difficult to find an anal. method sensitive enough to detect them. Here, we probed the mol. interaction between galactomannan, arabinoxylan, and β-glucan with gallic acid, cinnamic acid, acetylsalicylic acid, and acetaminophen, using advanced anal. methods, namely isothermal titration calorimetry (ITC) and in the form of gold-nanoparticles, transmission electron microscopy (TEM). The results obtained from ITC anal. were fully consistent with the results obtained from TEM. In short, the interaction of these fibers and small mols. was mainly entropically driven, hence involving hydrophobic type association and possible conformational changes of the polysaccharide. However, the enthalpy contribution (hydrogen interaction) is also significant, especially regarding interactions with the acetylsalicylic acid mol.

Angele-Martinez, Carlos published the artcilePolyphenol effects on CuO-nanoparticle-mediated DNA damage, reactive oxygen species generation, and fibroblast cell death, Name: Propyl 3,4,5-trihydroxybenzoate, the publication is Toxicology In Vitro (2022), 105252, database is CAplus and MEDLINE.

The ability of ten polyphenolic antioxidants to prevent CuO nanoparticle (NPCuO) and H2O2-mediated DNA damage and cytotoxicity was investigated. Five of the polyphenols (MEPCA, PREGA, MEGA, ECG, and EGCG) prevent NPCuO/H2O2-mediated DNA damage (IC50 values of 7.5-800μM), three have no effect (PCA, VA, and EC), and two (GA and EGC) result in increased DNA damage. Most polyphenols had similar antioxidant/prooxidant activity in the presence of NPCuO or free copper ions. ESR (EPR) spectroscopy of reactive oxygen species (ROS) generated by NPCuO/H2O2 in the presence of representative polyphenols correlate with results of DNA damage studies: in the presence of NPCuO/H2O2, MEPCA prevents ROS formation, VA has no effect on ROS levels, and EGC increases ROS levels. EPR results with CuO nanoparticles washed to remove dissolved copper in solution (wCuO) in the presence of H2O2/ascorbate suggest that MEPCA prevents ROS formation on the nanoparticle surface in addition to preventing ROS formation from dissolved copper. In mouse fibroblast (L929) cells, combining NPCuO with H2O2 results in significantly greater cytotoxicity than observed for either component alone. After 3 h incubation with MEPCA or MEGA, the viability loss in L929 cells induced by NPCuO/H2O2 challenge was significantly rescued at physiol. relevant polyphenol levels (1μM). These studies show that polyphenols can protect DNA and inhibit cytotoxicity generated by NPCuO under oxidative stress conditions.

Hu, Chenghong published the artcileEster Oils Prepared from Fully Renewable Resources and Their Lubricant Base Oil Properties, Product Details of C10H12O5, the publication is ACS Omega (2021), 6(25), 16343-16355, database is CAplus and MEDLINE.

The work reports on the physicochem. and tribol. properties of gallate ester oils prepared from fully renewable resources, such as gallic acid and fatty acids. The ester structures were identified by proton NMR spectroscopy (¹H NMR), carbon NMR spectroscopy (¹³C NMR) and high-resolution mass spectra (HRMS) data. The d. at 20°C (d₂₀), kinematic viscosity (KV), viscosity index (VI), pour point (PP), flash point (FP), thermal and oxidative stabilities, friction-reducing and antiwear properties of gallate ester oils were evaluated. The tribol. properties of gallate ester oils as lubricants for steel, copper, and aluminum tribo-pairs can be compared with those of the com. available lubricating oil tris(2-ethylhexyl) trimellitate (Phe-3C_i8), but their viscosity-temperature characteristics, thermal and oxidative stabilities are better than those of Phe-3C_i8. More importantly, they have much higher biodegradabilities than Phe-3C_i8. The study of the lubrication mechanism shows that the phys. and/or chem. adsorption film formed by gallate ester mols. between friction pairs is the key factor for them to obtain friction-reducing and antiwear properties.
