Zheng, Jianxia; Elangovan, Saravanakumar; Valyaev, Dmitry A.; Brousses, Remy; Cesar, Vincent; Sortais, Jean-Baptiste; Darcel, Christophe; Lugan, Noel; Lavigne, Guy published the artcile< Hydrosilylation of Aldehydes and Ketones Catalyzed by Half-Sandwich Manganese(I) N-Heterocyclic Carbene Complexes>, Formula: C6H9NO, the main research area is aldehyde ketone hydrosilylation manganese heterocyclic carbene complex catalyst.

Easily available manganese(I) N-heterocyclic carbene (NHC) complexes, Cp(CO)2Mn(NHC), obtained in one step from industrially produced cymantrene, were evaluated as pre-catalysts in the hydrosilylation of carbonyl compounds under UV irradiation Complexes with NHC ligands incorporating at least one mesityl group led to the most active and selective catalytic systems. A variety of aldehydes (13 examples) and ketones (11 examples) were efficiently reduced under mild conditions [Cp(CO)2Mn(IMes) (1 mol%), Ph2SiH2 (1.5 equiv), hν (350 nm), toluene, 25°, 1-24 h] with good functional group tolerance.

Maji, Milan; Kundu, Sabuj published the artcile< Cooperative ruthenium complex catalyzed multicomponent synthesis of pyrimidines>, Computed Properties of 403-41-8, the main research area is ruthenium complex catalyst multicomponent preparation pyrimidine.

A new set of 2-(2-benzimidazolyl) pyridine ligand based air and moisture stable ruthenium complexes were synthesized and characterized. The catalytic behaviors of these complexes were evaluated towards the multicomponent synthesis of highly substituted pyrimidines directly from various amidines, primary alcs., and secondary alcs. Among all the metal complexes, 2-hydroxypyridine and benzimidazole fragments containing complex I showed the best reactivity in this reaction. In addition, the N-H proton of benzimidazole and the hydroxyl group of pyridine played a critical role in enhancing catalytic activity. Several control experiments and mechanistic studies were carried out to understand this multicomponent synthesis of pyrimidines using complex I.

Papanastasiou, Stella A.; Ioannou, Charalampos S.; Papadopoulos, Nikos T. published the artcile< Oviposition-deterrent effect of linalool - a compound of citrus essential oils - on female Mediterranean fruit flies, Ceratitis capitata (Diptera: Tephritidae)>, COA of Formula: C10H18O, the main research area is Citrus Malus Ceratitis oviposition essential oil linalool; egg-laying; host; medfly; repellent effect.

We tested whether different linalool concentrations, application methods on fruit hosts and time since application elicited oviposition-deterrence on medfly, from bitter oranges, apples and nectarines, under constant laboratory conditions. We also tested possible repellent properties of linalool on adult medflies in field conditions. Females drilled fewer oviposition stings and deposited fewer eggs per fruit in all linalool-treated hosts. Spraying and topical-droplet application were the most efficient methods on bitter oranges, although spraying was the least effective method in apples. Bitter oranges and nectarines that were offered to females immediately post-exposure to linalool received more oviposition stings and eggs than those offered 3 days post-exposure to linalool solutions Conversely, apples tested 3 days following linalool application received significantly more oviposition stings and eggs than those tested immediately and 1 day post-exposure. More adults in total, and more females, were captured in traps located on untreated-control than on linalool-treated trees, especially in citrus hosts. Linalool has a potential future use in environmentally friendly control strategies against C. capitata.

Wang, Rongzhou; Han, Xingyou; Xu, Jing; Liu, Peng; Li, Feng published the artcile< Transfer Hydrogenation of Ketones and Imines with Methanol under Base-Free Conditions Catalyzed by an Anionic Metal-Ligand Bifunctional Iridium Catalyst>, HPLC of Formula: 403-41-8, the main research area is transfer hydrogenation ketone imine methanol; anionic metal ligand bifunctional iridium catalyst transfer hydrogenation.

An anionic iridium complex [Cp*Ir(2,2′-bpyO)(OH)][Na] was found to be a general and highly efficient catalyst for transfer hydrogenation of ketones and imines with methanol under base-free conditions. Readily reducible or labile substituents, such as nitro, cyano, and ester groups, were tolerated under present reaction conditions. Notably, this study exhibits the unique potential of anionic metal-ligand bifunctional iridium catalysts for transfer hydrogenation with methanol as a hydrogen source.

Malaguarnera, Lucia published the artcile< Influence of resveratrol on the immune response>, Electric Literature of 501-36-0 , the main research area is review resveratrol immune response; B lymphocytes; T lymphocytes; immune response; macrophages; natural killer; resveratrol.

A review. Resveratrol is the most well-known polyphenolic stilbenoid, present in grapes, mulberries, peanuts, rhubarb, and in several other plants. Resveratrol can play a beneficial role in the prevention and in the progression of chronic diseases related to inflammation such as diabetes, obesity, cardiovascular diseases, neurodegeneration, and cancers among other conditions. Moreover, resveratrol regulates immunity by interfering with immune cell regulation, proinflammatory cytokines’ synthesis, and gene expression. At the mol. level, it targets sirtuin, adenosine monophosphate kinase, nuclear factor- κB, inflammatory cytokines, anti-oxidant enzymes along with cellular processes such as gluconeogenesis, lipid metabolism, mitochondrial biogenesis, angiogenesis, and apoptosis. Resveratrol can suppress the toll-like receptor (TLR) and pro-inflammatory genes’ expression. The antioxidant activity of resveratrol and the ability to inhibit enzymes involved in the production of eicosanoids contribute to its anti-inflammation properties. The effects of this biol. active compound on the immune system are associated with widespread health benefits for different autoimmune and chronic inflammatory diseases. This review offers a systematic understanding of how resveratrol targets multiple inflammatory components and exerts immune-regulatory effects on immune cells.

Gholinejad, Mohammad; Dasvarz, Neda; Shojafar, Mohammad; Sansano, Jose M. published the artcile< Starch functionalized creatine for stabilization of gold nanoparticles: Efficient heterogeneous catalyst for the reduction of nitroarenes>, Quality Control of 5344-90-1, the main research area is starch creatine stabilization gold nanoparticle catalyst reduction nitroarene.

Selective reduction of nitroarom. pollutants into amines with recoverable and reusable heterogeneous catalysts is highly desirable. Herein, we prepared and characterized an efficient novel catalyst comprising 4 nm size Au nanoparticles supported on creatine modified starch. Using this catalyst, efficient reduction of nitroarenes into amines at room temperature in aqueous media was achieved. The presence of creatine in the structure of the catalyst plays important role in amount of Au loading, efficiency of the catalyst, recycling times, and leaching of Au compared to starch supported Au without creatine.
