《Structure-based discovery of novel 4-(2-fluorophenoxy)quinoline derivatives as c-Met inhibitors using isocyanide-involved multicomponent reactions》 was published in European Journal of Medicinal Chemistry in 2020. These research results belong to Nan, Xiang; Li, Hui-Jing; Fang, Sen-Biao; Li, Qin-Ying; Wu, Yan-Chao. Formula: C5H13NO2 The article mentions the following:

In this study, two novel series of 6,7-dimethoxy-4-(2-fluorophenoxy)quinoline derivatives containing α-acyloxycarboxamide I [R1 = Me, n-Pr, t-Bu, cyclohexyl, phenyl; R2 = cyclopentyl, 2-thienyl, Ph, etc.] or α-acylaminoamide II [R3 = H, n-Bu, Ph, etc.] scaffolds were designed, synthesized and evaluated for their in-vitro biol. activities against c-Met kinase and four cancer cell lines (H460, HT-29, MKN-45 and MDA-MB-231). Most of the target compounds I and II exhibited moderate to significant potency and possessed selectivity for H460 and HT-29 cancer cell lines. The preliminary structure-activity relationships indicated that α-acyloxycarboxamide or α-acylaminoamide as 5-atom linker contributed to the antitumor potency. Among these compounds, compound I [R1 = t-Bu, R2 = 4-fluorophenyl] (c-Met IC50 = 2.43 nM, a multitarget tyrosine kinase inhibitor) exhibited the most potent inhibitory activities against H460, HT-29 and MDA-MB-231 cell lines with IC50 of 0.14 ± 0.03μM, 0.20 ± 0.02μM and 0.42 ± 0.03μM, which were 1.7-, 1.3- and 1.6-fold more active than foretinib, resp. In addition, concentration-dependent assay and time-dependent assay indicated compound I [R1 = t-Bu, R2 = 4-fluorophenyl] inhibited the proliferation of H460 cell in a time and concentration dependent manner. Moreover, docking studies revealed the common mode of interaction with the c-Met binding site, suggesting that compound I [R1 = t-Bu, R2 = 4-fluorophenyl] is a potential candidate for cancer therapy deserving further study.

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.

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)

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.

The title of the article was 《N-Methoxy-1,3-oxazinane nucleic acids (MOANAs) – a configurationally flexible backbone modification allows post-synthetic incorporation of base moieties》.Electric Literature of C9H10O2 The author mentioned the following in the article:

(2R,3S)-4-(Methoxyamino)butane-1,2,3-triol was converted into a protected phosphoramidite building block and incorporated into the middle of a short DNA oligonucleotide. O1 and O3 of the (2R,3S)-4-(methoxyamino)butane-1,2,3-triol were engaged in phosphodiester linkages, leaving O2 and the methoxyamino function available to form an N-methoxy-1,3-oxazinane ring through reaction with an aldehyde. In modified oligonucleotides thus obtained, the oxazinane ring formally replaces the furanose ring and the aldehyde, the base moiety of natural nucleosides. The feasibility of synthesizing base-modified oligonucleotides by this approach was demonstrated with several aromatic and aliphatic aldehydes featuring various functional groups.

In 2022,Gutierrez, Mario; Garcia, Eduardo; Monterde, Cristina; Sanchez, Felix; Douhal, Abderrazzak published an article in Physical Chemistry Chemical Physics. The title of the article was 《Modulating the spectroscopy and dynamics of a proton-transfer dye by functionalizing with phenyl groups》.COA of Formula: C8H8O2 The author mentioned the following in the article:

Mols. undergoing excited-state proton transfer (ESPT) reactions are among the most interesting systems from spectroscopic and photophys. viewpoints. These mols. can be further functionalized with electron donating or accepting groups, inducing intramol. charge transfer (ICT) events, which might be coupled to the ESIPT ones, conferring them with different spectroscopic and photophys. properties, which can be essential to implement the related materials in many key scientific and technol. fields. Here, authors report new benzimidazole derivatives that are functionalized with a Ph group, 2-(5,10-diphenyl-1H-phenanthro[9,10-d]imidazol-2-yl)phenol (DP-HPPI), and its methylated equivalent, 2-(2-methoxyphenyl)-5,10-diphenyl-1H-phenanthro[9,10-d]imidazole (DP-MPPI). The results prove that these mols. in solutions undergo an ultrafast ICT (400-700 fs) reaction. Addnl., DP-HPPI also undergoes a reversible ESIPT process in dichloromethane. However, this is precluded in acetonitrile due to the involvement of intermol. H-bonds in this solvent. These results provide key insights into the development of proton-transfer materials with bespoke spectral and photodynamical properties. In the experiment, the researchers used many compounds, for example, 2-Methoxybenzaldehyde(cas: 135-02-4COA of Formula: C8H8O2)
