The Name is 4-Nitrobenzoic acid. Through research, I have a further understanding and discovery of 62-23-7.

Non-solvent and non-additive oxidation of secondary benzylic C-H bonds to aromatic ketones utilizing simple metalloporphyrins as catalysts and O-2 was investigated systematically. Based on systematical studies on reaction parameters, such as the structures of porphyrins, the types of central metals, the amount of catalyst, the pressure of oxygen, and the temperature, most aromatics with secondary benzylic C-H had been converted efficiently and selectively to their corresponding aromatic ketones catalyzed by the optimized metalloporphyrin catalyst T(2,3,6-triCl)PPCo. And the selectivity towards aromatic ketones reached up to 80 %-95 % with acceptable conversions in lower catalyst-loading (2.4 x 10(-3)%, mol/mol). The highest selectivity was achieved for substrate 1,2,3,4-tetrahydronaphthalene with the selectivity of 95.0 % in the conversion of 46.3 %. The superior catalytic performance of T(2,3,6-triCl)PPCo could be mainly ascribed to its excellent plane structure, superior ability for electron transfer and low positive charge around the central metal. All of above properties promoted the formation of catalytic active species high-valence cobalt-oxo complexes, and facilitated the approach of substrates to the catalytic active centers. This work presented an optimized balance among higher selectivity, milder conditions, lower catalyst-loading, and simpler catalysts compared with current documents, which was not only an efficient, practical and significant strategy to functionalize the widely available aromatics possessing secondary benzylic C-H with high efficiency and selectivity under milder conditions, but also an important instance in the effective functionalization and utilization of other C-H bonds employing optimized catalytic systems based on metalloporphyrins.

The development of sub-nanometric metal particles (<1 nm) as advanced heterogeneous catalysts has received considerable interest due to their outstanding catalytic performance, while the synthesis and stabilization of sub-nanometric catalysts (SNCs) without using additional surface capping agents remains a challenge. Herein, we report the synthesis of novel three-dimensional pyrenyl graphdiyne (Pyr-GDY) ultrafine nanofibers (3-10 nm), which can serve as an ideal substrate for electroless deposition and stabilization of Pd SNCs through the terminal uncoupled acetenyl groups in Pyr-GDY, with an average Pd particle size of only 0.83 nm. The as-synthesized Pd/Pyr-GDY composite shows extremely high catalytic activities for the reduction of nitroarenes to arylamines and Suzuki coupling reactions, 300 and 25 times higher than those of commercial Pd/C, respectively. The outstanding catalytic performance can be ascribed to the sub-nanometric Pd particles with a clean surface, and the unique three-dimensional network structure of Pyr-GDY, being favorable for rapid mass transfer. Our result provides an ideal carbon material for electroless deposition and stabilization of other SNCs with a clean surface, which will display outstanding catalytic activity for various catalytic reactions.

Lignin is a biodegradable, abundant and renewable natural polymer on earth. In this study, deep eutectic solvents (DESs)-modified lignin heterogeneous catalysts were prepared for the first time via a facile acid-base interaction between choline chloride (ChCl) and p-aminobenzoic acid (PABA) or its derivatives, which were used to efficiently catalyze the cycloaddition of CO2 and terminal epoxides under green and mild conditions. Among them, lignin-ChCl-PABA was found to exhibit the highest catalytic activity for the cycloaddition of epoxides in the presence of 1.0 MPa of CO2 while retaining high selectivity, which far outperformed those achieved on the homogeneous EDSs catalytic system. A series of cyclic carbonates could be obtained in high yields (90-99%), and lignin-ChCl-PABA was stable and reusable for the cycloaddition reaction (84% yield after 5 recycles). The attaching DES of ChCl/PABA onto the functional lignin increased the catalytic activity and also made the catalyst easier to recycle from the reaction mixture. The -OH and -NH2 groups on the surface of lignin-ChCl-PABA played a very important role in the acceleration of the cycloaddition reaction under solvent free conditions.

Direct C-H bond oxidation of organic materials, and producing the necessary oxygenated compounds under mild conditions, has attracted increasing interest. The selective oxidation of various alkylbenzenes was carried out by means of a new catalyst containing VO2+ species supported on silica-coated Fe3O4 nanoparticles usingt-butyl hydroperoxide as an oxidant at room temperature in H2O or solvent-free media. The chemical and structural characterization of the catalyst using several methods such as FTIR spectroscopy, XRD, FETEM, FESEM, SAED, EDX and XPS showed that VO2+ is covalently bonded to the silica surface. High selectivity and excellent conversion of various toluene derivatives, with less reactive aliphatic (sp(3)) C-H bonds, to related benzoic acids were quite noticeable. The aerobic oxygenation reaction of these alkylbenzenes was studied under the same conditions. All the results accompanied by sustainability of the inexpensive and simple magnetically separable heterogeneous catalyst proved the important criteria for commercial applications.

Two series of racemic goniothalamin analogues displaying nitrogen-containing groups were designed and synthesized. A total of 19 novel analogues were evaluated against a panel of four different cancer cell lines, along with the normal prostate cell line PNT2 to determine their selectivity. Among them, goniothalamin chloroacrylamide 13 e displayed the lowest IC50 values for both MCF-7 (0.5 mu m) and PC3 (0.3 mu m) cells, about 26-fold more potent than goniothalamin (1). Besides its higher potency, compound 13 e also displayed much higher selectivity than goniothalamin. In contrast, goniothalamin isobutyramide 13 c was the most potent analogue against Caco-2 cells (IC50=0.8 mu m), about 10-fold more potent and 17-fold more selective than 1. These results reveal the potential of compounds 13 c and 13 e for further in vivo studies, representing the first goniothalamin analogues with IC50 values in the low micromolar range and high selectivity against MCF-7, Caco-2, and PC3 cancer cell lines.

A series of 1,2,4-triazole derivatives 1-14 was synthesized to investigate their neuroprotective effects and mechanisms of action. Compounds 5-11 noticeably protected PC12 cells from the cytotoxicity of H2O2 or sodium nitroprusside (SNP). Compound 11 was the most effective derivative. Compound 11 chelated Fe (II) iron, scavenged reactive oxygen species (ROS), and restored the mitochondrial membrane potential (MMP). Moreover, it enhanced the activity of the antioxidant defense system by increasing the serum level of superoxide dismutase (SOD) and promoting the nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2). Compound 11 caused certain improvements in behavior, the cerebral infarction area, and serum levels of biochemical indicators (TNF-alpha, IL-10, SOD and MDA) in a rat MCAO model. The lethal dose (LD50) of compound 11 in mice receiving intraperitoneal injections was greater than 400 mg/kg. Meanwhile, pharmacokinetic experiments revealed high bioavailability of this compound after both oral and intravenous administration (F = 60.76%, CL = 0.014 mg/kg/h) and a longer half-life (4.26 and 5.11 h after oral and intravenous administration, respectively). Based on these findings, compound 11 may be a promising neuroprotectant for the treatment of ischemic stroke. (C) 2020 Elsevier Masson SAS. All rights reserved.

The insect beta-N-acetylhexosaminidase OfHex1 from Ostrinia furnacalis (one of the most destructive agricultural pests) has been considered as a promising pesticide target. In this study, a series of novel and readily available ureido thioglycosides were designed and synthesized based on the catalytic mechanism and the co-crystal structures of OfHex1 with substrates. After evaluation via enzyme inhibition experiments, thioglycosides 11c and 15k were found to have inhibitory activities against OfHex1 with the K-i values of 25.6 mu M and 53.8 mu M, respectively. In addition, all these ureido thioglycosides exhibited high selectivity toward OfHex1 over hOGA and HsHexB (K-i > 100 mu M). Furthermore, to investigate the inhibitory mechanism, the possible binding modes of 11c and 15k with OfHex1 were deduced based on molecular docking analysis. This work may provide useful structural starting points for further rational design of potent inhibitors of OfHex1.
