Yao, Haiyun published the artcileSynthesis, Crystal Structure, and Luminescence Properties of the Iso-Reticular Series of Lanthanide Coordination Polymers Synthesized from Hexa-Lanthanide Molecular Precursors, Recommanded Product: 4-Nitrophenylacetic acid, the publication is Inorganic Chemistry (2022), 61(12), 4895-4908, database is CAplus and MEDLINE.

Microwave-assisted reactions in DMSO, between a hexa-lanthanide octahedral complex ([Ln₆(¦Ì₆-O)(¦Ì₃-OH)₈(NO₃)₆(H₂O)₁₂¡¤2NO₃¡¤2H₂O] with Ln = Nd-Yb plus Y) and either 3-halobenzoic acid (hereafter symbolized by 3-xbH with x = f or c for fluoro or chloro, resp.) or 4-halobenzoic acid (hereafter symbolized by 4-xbH with x = f, c, or b for fluoro, chloro, or bromo, resp.), lead to 1-dimensional lanthanide coordination polymers. These coordination polymers are almost iso-reticular. The crystal structure is described from the coordination polymer with chem. formula [Tb(4-fb)₃(DMSO)(H₂O)₂¡¤DMSO]_¡Þ obtained from 4-fluorobenzoic acid (4-fbH) and the Tb³⁺-based octahedral complex: It crystallizes in the triclinic system, space group P1? (n¡ã2), with the following cell parameters: a 9.8561(9), b 10.5636(9), c 15.1288(15) ?, ¦Á 100.840(3), ¦Â 95.552(3), ¦Ã 110.482(3)¡ã, and Z = 2. It can be described from 1-dimensional mol. chains. Luminescence properties of the Tb and Eu derivatives were measured and compared vs. the halo-function and its position (meta or para). Some mol. alloys also were prepared to estimate the strength of the intermetallic energy transfers. To confirm that the hexa-nuclear complexes (and not the halogenated ligand) have a structuring effect for the formation of the straight chain-like mol. motif, another coordination polymer with chem. formula [Tb(4-npa)₃DMSO¡¤DMSO¡¤H₂O]_¡Þ (4-npaH = 4-nitro-phenyl-HOAc) was prepared It crystallizes in the triclinic system, space group P1? (n¡ã2) with the following cell parameters: a 7.8784(8), b 14.8719(16), c 15.2753(17) ?, ¦Á 73.612(4), ¦Â 86.406(4), ¦Ã 83.104(4)¡ã, and Z = 2. Its crystal structure can be described from a mol. motif that is similar to the one observed in the five previous crystal structures which confirms the structuring effect of the hexa-nuclear complexes.

A simple, efficient and environmentally benign method has been discussed for the synthesis of aldehydes and ketones by the oxidative decarboxylation of phenylacetic acid under ligand free condition using simple, efficient, preparatively easy, magnetically recoverable and low cost spinel CuFe₂O₄ nanoparticles. The catalyst was characterized using powder-XRD, FTIR, FE-SEM, EDX, VSM and HRTEM. The recyclability was examined and the results showed that the catalyst remained almost equally active up to five consecutive cycles. Spinel Structured Copper Ferrite is a very efficient nano catalyst for Oxidative decarboxylation of Ph acetic acids and can be reused up to five cycles without significant loss in catalytic activity.

A simple and efficient protocol was developed to access sym. and unsym. 2,5-disubstituted 1,3,4-oxadiazoles from arylacetic acids and hydrazides via copper-catalyzed dual oxidation under an oxygen atm. Oxidative decarboxylation of arylacetic acids and oxidative functionalization of the imine C-H bond were the key steps. This was the first example of the synthesis of 2,5-disubstituted 1,3,4-oxadiazoles through dual oxidation in one-pot. Avoidance of the expensive ligand and high yield of the products were advantageous features of the developed method.

Decarboxylative oxygenation of carboxylic acids using a non-heme manganese catalyst under blue light irradiation with O₂ as the sole oxidant. Featuring mild reaction conditions, the protocol allowed readily available carboxylic acids to be converted into a wide variety of valuable aldehydes, ketones and amides. Mechanistic studies indicated that the decarboxylation and oxygenation involved the formation of active Mn-oxygen species.

A new unsym. diamine, 4-(2-aminophenoxy)-4′-aminostilbene was successfully synthesized and used to synthesize stilbene-containing sulfonated polyimides. 2,2′-Benzidine-disulfonic acid, 1,4,5,8-naphthalene tetracarboxylic dianhydride and different mole ratios of 4-(2-aminophenoxy)-4′-aminostilbene and 2-bis(4-(4-aminophenoxy)phenyl) hexafluoropropane were used for the synthesis of stilbene-containing polyimides with sulfonic acid groups. The synthesized polymers were characterized using various physicochem. characterization techniques such as NMR spectroscopy, IR spectroscopy, differential scanning calorimetry, thermogravimetric anal. and electrochem. impedance spectroscopy. Furthermore, the viscosity, water uptake, ion exchange capacity, swelling ratio, hydrolytic stability, oxidative stability, mech. properties and proton conductivity of the synthesized membranes were also analyzed. Sulfonated polyimide membranes showed a water uptake capacity of 18.93-28.89%, proton conductivity of 0.028-0.039 S cm^-1 at 30°C, ion exchange capacity of 1.469 meq g^-1 and hydrolytic stability of 40-44 h at 80°C. The solubility of the sulfonated polyimide membranes was improved when unsym. diamine was used to prepare sulfonated polyimides.

Musa, Musiliyu A. published the artcileIdentification of 7,8-dihydroxy-3-phenylcoumarin as a reversible monoamine oxidase enzyme inhibitor, HPLC of Formula: 104-03-0, the publication is Journal of Biochemical and Molecular Toxicology (2021), 35(2), e22651, database is CAplus and MEDLINE.

We herein report the biol. evaluation of 3-arylcoumarin derivatives (3a-l) as potential human monoamine oxidase-A and -B (hMAO-A and hMAO-B) inhibitors. The result indicated that 7,8-dihydroxy-3-(4-nitrophenyl)coumarin (3j) was most effective against MAO-A (inhibition concentration [IC₅₀] = 6.46 ± 0.02μM) and MAO-B (IC₅₀ = 3.8 ± 0.3μM) enzymes than other synthesized compounds and reference compounds (pargyline and moclobemide). Furthermore, compound (3j) showed (a) nonselectivity against hMAO enzymes, (b) reversible hMAO enzymes inhibition, and (c) neuroprotection against H₂O2-treated human neuroblastoma (N2a) cells. Finally, a mol. modeling study revealed that the hMAO enzymes inhibitory activity of the compound (3j) may be due to the orientation where the nitro (NO2) group lies deep into the receptor and the Ph ring directed toward flavin adenosine dinucleotide via hydrogen bond interaction, and possible π-π interaction with various important residues. Thus, the results of the present study demonstrate that compound (3j) can be considered as a promising scaffold for the development of hMAO-A and hMAO-B inhibitors.
