The title of the article was 《Highly selective Suzuki reaction catalyzed by a molecular Pd-P-MOF catalyst under mild conditions: role of ligands and palladium speciation》.Synthetic Route of C7H7BrO The author mentioned the following in the article:

A molecularly-defined heterogeneous palladium catalyst based on a phosphine-metal-organic framework (P-MOF) ligand system was reported. This catalyst performed Suzuki reactions of aryl bromides and Ph boronic acid to afford biaryls R-R1 [R = Ph; R1 = 3-MeC6H4, 3-OMeC6H4, 3-pyridyl, etc.] in exceptionally mild conditions while displayed a unique selectivity, higher than that achieved using Pd(PPh3)4, a standard homogeneous catalyst. The new palladium P-MOF catalyst was active for a wide range of substrates. Determination of the palladium speciation showed that molecularly-defined palladium-phosphine sites catalyzed the Suzuki cross-coupling with very high selectivity, and that, when formed, palladium nanoparticles promoted hydrodehalogenation. The fraction of molecularly defined palladium was maximized by having excess of phosphine ligand in the system. After reading the article, we found that the author used 1-Bromo-3-methoxybenzene(cas: 2398-37-0Synthetic Route of C7H7BrO)

In 2022,Zhu, Longfei; Ye, Sen; Zhu, Jiazheng; Duan, Chengjie; Li, Kun; He, Guangke; Liu, Xiang published an article in ACS Sustainable Chemistry & Engineering. The title of the article was 《Tartaric Acid-Assisted Synthesis of Well-Dispersed Ni Nanoparticles Supported on Hydroxyapatite for Efficient Phenol Hydrogenation》.Computed Properties of C7H8O2 The author mentioned the following in the article:

Developing highly active nonnoble-metal-based heterogeneous catalysts for selective hydrogenation is a long-sought goal due to the scarcity and high price of noble metals. Herein, well-dispersed and small-sized Ni nanoparticles (NPs) supported on hydroxyapatite (Ni-TA/HAP) were prepared using a simple tartaric acid (TA)-assisted impregnation method, which is based on the coupling interaction of strong electrostatic adsorption between the HAP and TA and reactive metal-ligand chelation between Ni and TA. Under mild conditions (e.g., 1 mol % Ni, 3 bar H2 at 80°C), the as-synthesized Ni-TA/HAP exhibited excellent activity and selectivity (>99%) for the efficient hydrogenation of phenolic compounds to the corresponding cyclohexanols, as well as the controlled partial hydrogenation of N-heteroarenes. Characterization results revealed that TA addition could promote a better dispersion of Ni species and inhibit the aggregation of Ni NPs during the fabrication of the Ni-TA/HAP catalyst. An optimal TA dosage (nTA/nNi = 0.5) as well as a low Ni loading (1.0 weight %) coconstructed the favorable microstructure of the well-dispersed Ni nanoparticles as the catalytic center. The hydrogenation was boosted by small-sized Ni nanoparticles with a high ability for H2 activation and HAP with both base and acid sites for appreciating phenol absorption. The experimental part of the paper was very detailed, including the reaction process of m-Methoxyphenol(cas: 150-19-6Computed Properties of C7H8O2)

m-Methoxyphenol(cas: 150-19-6) may be used as an analytical standard for the determination of the analyte in wine, coffee beans, wood samples, and mainstream smoke by gas chromatography (GC) based techniques.Computed Properties of C7H8O2

The article conveys some information:

Novel imidazole-based TGFβR1 inhibitors were identified and optimized for potency, selectivity, and pharmacokinetic and physicochem. characteristics. Herein, we report the discovery, optimization, and evaluation of a potent, selective, and orally bioavailable TGFβR1 inhibitor, 10 (BMS-986260). This compound demonstrated functional activity in multiple TGFβ-dependent cellular assays, excellent kinome selectivity, favorable pharmacokinetic properties, and curative in vivo efficacy in combination with anti-PD-1 antibody in murine colorectal cancer (CRC) models. Since daily dosing of TGFβR1 inhibitors is known to cause class-based cardiovascular (CV) toxicities in preclin. species, a dosing holiday schedule in the anti-PD-1 combination efficacy studies was explored. An intermittent dosing regimen of 3 days on and 4 days off allowed mitigation of CV toxicities in one month dog and rat toxicol. studies and also provided similar efficacy as once daily dosing.

Safety of 2-MethoxybenzaldehydeIn 2019 ,《Synthesis of new low-viscous sulfonic acid-functionalized ionic liquid and its application as a Bronsted liquid acid catalyst for the one-pot mechanosynthesis of 4H-pyrans through the ball milling process》 appeared in Journal of Molecular Liquids. The author of the article were Khaligh, Nader Ghaffari; Mihankhah, Taraneh; Johan, Mohd. Rafie. The article conveys some information:

In the present study, a new low-viscous sulfonic acid-functionalized ionic liquid (SAIL) viz. 4,4′-trimethylene-N,N’-sulfonic acid-dipiperidinium chloride was synthesized and characterized by FTIR, 1D and 2D NMR, and Mass spectra. Then, some properties of new SAIL were determined including pH, viscosity, d., and solubility in some common solvents. The catalytic activity of new SAIL was demonstrated for the one-pot mechanosynthesis of pyrano[4,3-b]pyrans, dihydropyrano[3,2-c]chromene and tetrahydrobenzo[b]pyrans using planetary ball mill under solvent-free conditions. This current mechanosynthesis methodol. for the synthesis of 4H-pyran-annulated heterocyclic scaffolds displays a combination of the synthetic virtues of conventional multi-component reaction with ecol. benefits and convenience of a simple mechanocatalytic procedure. New SAIL was easily recycled and reused several times with no significant loss of activity.

SDS of cas: 135-02-4In 2020 ,《Experimental and DFT mechanistic insights into one-pot synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones under catalysis of DBU-based ionic liquids》 appeared in New Journal of Chemistry. The author of the article were Fallah-Ghasemi Gildeh, Sara; Mehrdad, Morteza; Roohi, Hossein; Ghauri, Khatereh; Fallah-Ghasemi Gildeh, Sahar; Rad-Moghadam, Kurosh. The article conveys some information:

Benzylation of DBU followed by anion exchange of the resulting salt with trifluoroacetate gave nearly quant. ionic liq [Bn-DBU][TFA]. It is shown here to be an efficient catalyst for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones I (Ar = 4-nitrophenyl, 3-chlorophenyl, 2-methylphenyl, etc.; X = CN, COOEt) via the three-component reaction of phthalhydrazide, aromatic aldehydes ArCHO, and active α-methylene nitriles XCH2CN. DFT calculations at the B3LYP/SVP level and the exptl. results are in agreement with a three-step mechanism for this reaction. Based on the DFT calculations, the catalytic effect largely arises from the intrinsic ionic properties of the ionic liquid rather than its action as a simple base. These calculations also predict the existence of two close-in-energy activated complexes whose rate determining roles and energies depend on their interaction with the anionic component of the ionic liquid, as [Bn-DBU][TFA] has shown a higher catalytic activity than [Bn-DBU][OAc]. This mechanistic approach opens up new and promising insights into the rational design of ionic liquid catalysts for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones I. The synthetic method presented here has several prominent advantages.

The article contains the following contents:

A rapid response is necessary to contain emergent biol. outbreaks before they can become pandemics. The novel coronavirus (SARS-CoV-2) that causes COVID-19 was first reported in Dec. of 2019 in Wuhan, China and reached most corners of the globe in less than two months. In just over a year since the initial infections, COVID-19 infected almost 100 million people worldwide. Although similar to SARS-CoV and MERS-CoV, SARS-CoV-2 has resisted treatments that are effective against other coronaviruses. Crystal structures of two SARS-CoV-2 proteins, spike protein and main protease, have been reported and can serve as targets for studies in neutralizing this threat. We have employed mol. docking, mol. dynamics simulations, and machine learning to identify from a library of 26 million mols. possible candidate compounds that may attenuate or neutralize the effects of this virus. The viability of selected candidate compounds against SARS-CoV-2 was determined exptl. by biolayer interferometry and FRET-based activity protein assays along with virus-based assays. In the pseudovirus assay, imatinib and lapatinib had IC50 values below 10μM, while candesartan cilexetil had an IC50 value of approx. 67μM against Mpro in a FRETbased activity assay. Comparatively, candesartan cilexetil had the highest selectivity index of all compounds tested as its half-maximal cytotoxicity concentration 50 (CC50) value was the only one greater than the limit of the assay (>100μM). In the experiment, the researchers used many compounds, for example, 6-(3-(Adamantan-1-yl)-4-methoxyphenyl)-2-naphthoic acid(cas: 106685-40-9Application of 106685-40-9)
