Moreira, Denise Ramos; Chaves, Pedro Oribio Bastos; Ferreira, Elano Nery; Arruda, Tathilene Bezerra Mota Gomes; Rodrigues, Francisco Eduardo Arruda; Neto, Joao Francisco Camara; Petzhold, Cesar Liberato; Maier, Martin E.; Ricardo, Nagila Maria Pontes Silva published the artcile< Moringa polyesters as eco-friendly lubricants and its blends with naphthalenic lubricant>, Quality Control of 112-63-0, the main research area is Moringa polyester naphthalenic lubricant blend.

Due to the toxicity and low biodegradability, mineral lubricants have been sharing space with green lubricants. Moringa oleifera can grow naturally in dry regions with subtropical climates and the oil, rich in unsaturated compounds (79.87%), may be a potential feedstock for fuel and lubricant base stocks. Moringa oil was hydrolyzed and then esterified with polyols, trimethylolpropane (MTMPE) and pentaerythritol (MPEE), in the temperature range of 130-140 °C. P-toluene sulfonic acid (p-TSA) was used as the catalyst. The products obtained were characterized using 1H and 13C NMR, IR, and mass spectral techniques. The main physicochem. properties, the thermal behavior and toxicity against Artemia salina of products were evaluated. In addition, blends with the naphthenic lubricant, NH10, were prepared with 20%, 35%, and 50% of the Moringa esters. The synthesized samples have high viscosity indexes (VI = 170) and they were found to be non-toxic against A. salina (LC50>1000 ppm). MTMPE presented higher thermal stability and showed a m.p. of -38.5 °C, which reveals its potential for applications in very low temperatures Blends showed high viscosity indexes and reduced toxicity compared to pure NH10. The study revealed that moringa esters are interesting to be applied as environmental friendly lubricants or additives.

Jo, Jasmin; Schiff, David published the artcile< Current Considerations in the Treatment of Grade 3 Gliomas.>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is 1p/19q codeletion; IDH inhibitors; IDH mutation; Oligodendroglioma; WHO grade 3 astrocytoma.

OPINION STATEMENT: Treatment recommendations for grade 3 gliomas are guided by their histopathologic and molecular phenotype. In the 2021 WHO classification, these tumors are categorized into two types, grade 3 IDH mutant (IDHmt), 1p/19q codeleted oligodendroglioma and IDH mutant astrocytoma. Treatment consists of maximal safe surgery, followed by radiation therapy (RT) and alkylating agent-based chemotherapy. Based on the updated CATNON result, RT followed by temozolomide improves outcome in patients with non-codeleted grade 3 IDHmt astrocytoma. In patients with IDHmt, codeleted oligodendroglioma, the addition of procarbazine, CCNU, and vincristine regimen is the recommended treatment, based on large randomized controlled trials. These current treatments prolong the overall survival to up to 10 years in patients with grade 3 IDHmt astrocytoma and 14 years in grade 3 IDHmt codeleted oligodendroglioma. Treatment options at recurrence include re-resection, re-irradiation, and other cytotoxic chemotherapy; however, these are of limited benefit. Novel agents targeting IDH mutation and its metabolic effects are currently under investigation to improve the outcome of these patients.

Alamudun, Sophya F.; Tanovitz, Kyle; Fajardo, April; Johnson, Kaitlind; Pham, Andy; Jamshidi Araghi, Tina; Petit, Andrew S. published the artcile< Structure-Photochemical Function Relationships in Nitrogen-Containing Heterocyclic Aromatic Photobases Derived from Quinoline>, Formula: C19H34O2, the main research area is nitrogen containing heterocyclic aromatic photobasicity structure photochem function relationship.

Photobases are compounds that become strong bases after electronic excitation. Recent exptl. studies have highlighted the photobasicity of the 5-R quinoline compounds, demonstrating a strong substituent dependence to the pKa*. In this paper, we describe our systematic study of how the thermodn. driving force for photobasicity is tuned through substituents in four families of nitrogen-containing heterocyclic aromatics We show that substituent position and identity both significantly impact the pKa*. We demonstrate that the substituent effects are additive and identify many disubstituted compounds with substantially greater photobasicity than the most photobasic 5-R quinoline compound identified previously. We show that the addition of a second fused benzene ring to quinoline, along with two electron-donating substituents, lowers the S0 → SPBS vertical excitation energy into the visible region while still maintaining a pKa* > 14. Overall, the structure-function relationships developed in this study provide new insights to guide the development of new photocatalysts that employ photobasicity.

Metz, N.; Lange, B.; Zentel, R.; Theato, P. published the artcile< Functionalized nanoparticles using active ester monomers as shell component>, Application of C9H3F5O2, the main research area is core shell polymer monodisperse nanoparticle preparation.

Colloidal photonic crystals were prepared from monodisperse core-shell particles. The shell is formed from a functional monomer, which can perform chem. reactions and the core from a standard monomer, which yields highly monodisperse colloids. It was possible to crystallize artificial opals with excellent optical properties, which have glycidylmethacrylate or different reactive ester monomers as shell material. Reactions on the functional surface of the colloids were carried out, which lead to a significant rise of mech. stability and to a modification of the surface with biomaterials and subsequent growth of a gold layer.

Jo, Ara; Bae, Jin Hee; Yoon, Yu Jeong; Chung, Tae Hun; Lee, Eun-Woo; Kim, Young-Ho; Joh, Hea Min; Chung, Jin Woong published the artcile< Plasma-activated medium induces ferroptosis by depleting FSP1 in human lung cancer cells>, Related Products of 347174-05-4, the main research area is FSP1 ferroptosis anticancer agent lung cancer.

Cold atm. plasma (CAP) that generates reactive oxygen species (ROS) has received considerable scientific attentions as a new type of anticancer. In particular, an indirect treatment method of inducing cancer cell death through plasma-activated medium (PAM), rather than direct plasma treatment has been well established. Although various cell death pathways such as apoptosis, necroptosis, and autophagy have been suggested to be involved in PAM-induced cell death, the involvement of ferroptosis, another type of cell death regulated by lipid ROS is largely unknown. This study reports, that PAM promotes cell death via ferroptosis in human lung cancer cells, and PAM increases intracellular and lipid ROS, thereby resulting in mitochondrial dysfunction. The treatment of cells with N-acetylcysteine, an ROS scavenging agent, or ferrostatin-1, a ferroptosis inhibitor, protects cells against PAM-induced cell death. Interestingly, ferroptosis suppressor protein 1 (FSP1) is downregulated upon PAM treatment. Furthermore, the treatment of cells with iFSP1, an inhibitor of FSP1, further enhances PAM-induced ferroptosis. Finally, this study demonstrates that PAM inhibits tumor growth in a xenograft model with an increase in 4-hydroxynoneal and PTGS2, a byproduct of lipid peroxidation, and a decrease in FSP1 expression. This study will provide new insights into the underlying mechanism and therapeutic strategies of PAM-mediated cancer treatment.

Feng, Junfeng; Fan, Teng; Ma, Changyue; Xu, Yangyang; Jiang, Jianchun; Pan, Hui published the artcile< Collaborative Conversion of Biomass Carbohydrates into Valuable Chemicals: Catalytic Strategy and Mechanism Research>, Electric Literature of 112-63-0, the main research area is biomass carbohydrate valuable chem catalytic strategy mechanism; collaborative conversion; levulinates; lignocellulose; zeolite.

Levulinate is one of the high added-value biomass-derived chems. that is primarily produced from hexoses in cellulose and hemicellulose. Producing levulinate from pentoses in hemicellulose that is extensively distributed in biomass is still highly challenging. In this study, biomass materials and carbohydrates (including cellulose, xylan, glucose, fructose, and xylose) were collaboratively converted into levulinates efficiently over various zeolites with ethanol/dimethoxymethane as cosolvents. The key process for converting pentoses into levulinates is the synthesis of intermediates (furfural) into alkoxy Me furfural via electrophilic substitution or their conversion into furfuryl alc. via in situ hydrogenation. The substitution was achieved by the synergic effect between bifunctional catalysts and cosolvents, which promotes conversion of furfural into alkoxy Me furfural via the electrophilic addition of alkoxy Me radicals. Hydrogenation of furfural into furfuryl alc. was impelled by the cooperative process between in situ generated H-donor from alc. solvents and zeolite catalysts. Moreover, a favorable yield of 21.05 mol % of levulinates was achieved by simultaneous and collaborative conversion of cellulose and hemicellulose with the one-pot process using ethanol/dimethoxymethane as a cosolvent and the zeolite with B and L acid sites as a catalyst.
