Silicon is not a natural component of gasoline but it can cause silica deposition in vehicle combustion system which may lead to severe engine failure. Silicon is present in gasoline in different chem. forms. The anal. of oil products by directly measuring under organic phase through inductively coupled plasma optical emission spectrometry (ICP-OES) is becoming a widely accepted approach as it is found to be simple and fast. The work focused on the influence of the sample nebulizer systems to different silicon chem. forms by ICP-OES. For a sample introduction system consisting of micronebulizer coupled to a cyclonic spray chamber, the results indicated that the ICP-OES signals depended strongly on the silicon chem. forms, and the higher emission intensities were attributed to the compound volatility. The variability of the signals induced by the different silicon compounds was less significant for the same nebulizer system with a temperature control device. Nevertheless, the interferences were not effectively mitigated. Nevertheless, direct injection high efficiency nebulizer (DIHEN) introduced in the present work could effectively mitigate the interferences of different silicon chem. forms, was suitable for the determination of silicon in gasoline. The quant. method with the potential DIHEN nebulizer system showed good linearity and the recoveries ranged from 92.8%-108.7%, the limit of detection was 0.05 mg·kg^-1. The relative standard deviation (RSD) was between 1.05% and 4.63%. Compared with the microwave digestion method, the proposed method was found to be highly simple, rapid, sensitive and accurate, which was foreseen a promising application for silicon determination in gasoline.

Jin, Hao published the artcileTransition-Metal-Free, General Construction of Thioamides from Chlorohydrocarbon, Amide and Elemental Sulfur, SDS of cas: 939-99-1, the publication is European Journal of Organic Chemistry (2021), 2021(23), 3403-3406, database is CAplus.

A general method for one-pot synthesis of thioamides is developed through a three-component reaction involving chlorohydrocarbon, amide and elemental sulfur. Such a strategy does not only avoid residual transition metal in the product but also prevent the generation of C-N coupling byproduct. The latter is prone to be generated when alkane halide and amine are present. With the protocol proposed in this work, both alkyl and aryl thioamides can be obtained in moderate to excellent yields with a high tolerance of various functional groups. External oxidants are not required in the reaction. In addition, the reaction mechanisms are addressed using a combination of controlling experiments and quantum chem. calculations

Wu, Qian published the artcileUnified synthesis of mono/bis-arylated phenols via Rh^III-catalyzed dehydrogenative coupling, Application In Synthesis of 209919-30-2, the publication is Chemical Science (2017), 8(1), 169-173, database is CAplus and MEDLINE.

A general strategy that allowed for the precise control of the oxidation pathways so that directing groups can be either preserved or cleaved was reported. It was found that N-phenoxyacetamides underwent ortho-arylation reactions with or without an external oxidant, yielding products with different oxidation states, notably the rare bis-arylated phenols. Notably, a unique rhodacycle intermediate was isolated, characterized by X-ray crystallog. and confirmed to be an active catalyst. Switching between internal and external oxidation could be a general strategy in diverse directed C-H functionalization reactions to realize bis-functionalized products.

Yuan, Xue published the artcileDiscovery of Potent and Selective Receptor-Interacting Serine/Threonine Protein Kinase 2 (RIPK2) Inhibitors for the Treatment of Inflammatory Bowel Diseases (IBDs), Safety of 2-Chloro-4-methylphenylboronic acid, the publication is Journal of Medicinal Chemistry (2022), 65(13), 9312-9327, database is CAplus and MEDLINE.

Receptor-interacting serine/threonine protein kinase 2 (RIPK2) has been demonstrated to be a promising target for treating inflammatory diseases. Herein, we describe the discovery and optimization of a series of RIPK2 inhibitors derived from an FLT3 inhibitor, CHMFL-FLT3-165. Compound 10w (I) was identified to possess an IC₅₀ value of 0.6 nM for RIPK2 and greater than 50,000-fold selectivity over its family homologous kinase RIPK1 (IC₅₀ > 30μM). It exhibited high kinase selectivity and inhibited RIPK2 to prevent NOD-induced cytokine production following muramyl dipeptide (MDP) stimulation. In an acute colitis model, compound 10w exerted better therapeutic effects than the JAK inhibitor filgotinib and the RIPK2 inhibitor WEHI-345. These robust results of in vitro and in vivo pharmacodynamic experiments demonstrate that RIPK2 as a therapeutic target shows potential abilities for the treatment of inflammatory bowel diseases.

Described herein are the palladium-catalyzed cross-coupling reactions of cyclobutanone-derived N-sulfonylhydrazones with aryl or benzyl halides, suggesting that the metal carbene process and β-hydride elimination can smoothly occur in strained ring systems. Structurally diversified products including cyclobutenes, methylenecyclobutanes, and conjugated dienes are selectively afforded in good to excellent yields. Preliminary success in asym. carbene coupling reactions in strained ring systems has been achieved, providing a promising route for the synthesis of enantioenriched four-membered-ring mols.

Hsu, Li-Na published the artcileCentral action of drugs for treatment of hypertension. I. Effect of reserpine on the conditioned response and blood pressure of normal dogs, Category: chlorides-buliding-blocks, the publication is Shengli Xuebao (1961), 24(3-4), 151-60, database is CAplus.

In 7 normal dogs given reserpine orally at 0.005-0.03 mg./kg. for 4-15 days, the positive conditioned response decreased and the reinforcement relation changed, sometimes with change in phase. The effect on the delayed conditioned response depends on dosage. A large dose (0.25 mg./kg.) seriously upset the equilibrium in stimulation-depression mechanisms to cause a nervous condition. With a daily dose of 0.005 or 0.01 mg./kg., no change in blood pressure was observed, but a change in conditioned response was quite distinct. This indicates that the cerebral cortex is more sensitive to resperine than the midbrain. It also indicates that the change in response is not induced by the action of resperine on the vasomotor center.

Singh, Pankaj Kumar published the artcileStructure based designing of triazolopyrimidone-based reversible inhibitors for kinases involved in NSCLC, Recommanded Product: 3-Chlorobenzylchloride, the publication is Bioorganic & Medicinal Chemistry Letters (2019), 29(13), 1565-1571, database is CAplus and MEDLINE.

Secondary acquired mutant EGFR (L858R-T790M) overexpressed NSCLC forms one of the prevalent form of resistant NSCLC. Another subset of resistant NSCLC includes amplified cMET in mutant EGFR derived tumors. Thus, in continuation to our previous work on these two major targets of resistant NSCLC, i.e., EGFR (L858R-T790M) and cMET, we are hereby reporting reversible inhibitors of these kinases. Out of 11 lead mols. reported in our previous study, we selected triazolo-pyrimidone (BAS 09867482) scaffold for further development of small mol. dual and reversible inhibitors. Analogs of lead with different substituents on the side ring were sketched and docked in both the target kinases, followed by mol. dynamic simulations. Analogs maintaining hydrophobic interaction with M790 in secondary acquired mutant EGFR (L858R-T790M) were selected and duly synthesized. In vitro biochem. evaluation of these mols. against EGFR (L858R-T790M) and cMET kinase, along with EGFR (L858R) kinase disclosed that three mols. were having significant dual kinase inhibitory potential with IC₅₀ values well below 100 nM. Further, in vitro anti-proliferative assay against three cell lines (A549, A431 and H460) was performed. Out of all, two compounds were having significant potency against these cell lines.
