Dong, Wenbo; Yang, Yi; Xiang, Yonggang; Wang, Shengyao; Wang, Pei; Hu, Jianxiang; Rao, Li; Chen, Hao published an article in 2021, the title of the article was A highly stable all-in-one photocatalyst for aryl etherification: the NiII embedded covalent organic framework.Computed Properties of 93-04-9 And the article contains the following content:

The efficient conversion of aryl bromides to the corresponding aryl alkyl ethers by dual Ni/photocatalysis has seen great progress, but difficulties of recycling the photosensitizer or Ni complexes cause problems of sustainability. Here, the authors report the design of a novel, highly stable vinyl bridge 2-dimensional covalent organic framework (COF) containing Ni, which combines the role of photosensitizer and reactive site. The as-prepared sp2c-COFdpy-Ni acts as an efficient heterogeneous photocatalyst for C-O cross coupling. The sp2c-COFdpy-Ni can be completely recovered and used repeatedly without loss of activity, overcoming the limitations of the prior methods. Preliminary studies reveal that strong interlayer electron transfer may facilitate the generation of the proposed intermediate sp2c-COFdpy-NiI in a bimol. and self-sustained manner. This all-in-one heterogeneous photocatalyst exhibits good compatibility of substrates and tolerance of functional groups. The successful attempt to expand the 2-dimensional COFs with this new catalyst into photocatalytic organic transformation opens an avenue for photoredox/transition metal mediated coupling reactions. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Computed Properties of 93-04-9

On July 31, 2021, Kong, Xiangchen; Liu, Chao; Xu, Weicong; Han, Yue; Fan, Yuyang; Lei, Ming; Li, Ming; Xiao, Rui published an article.COA of Formula: C8H10O The title of the article was Catalytic hydroprocessing of stubborn lignin in supercritical methanol with Cu/CuMgAlOx catalyst. And the article contained the following:

Stubborn lignin (SL) is the thermochem. stable fragment generated from biomass utilization (e.g., pyrolysis, hydrolysis, fermentation, pulping), which is comparatively difficult to be further depolymerized into value-added bio-products. The cleavage of the stubborn linkages within the structure of SL, such as C-C, α-O-4, and 4-O-5 linkages, is the key for its valorization. Herein, we investigated the depolymerization of SL through catalytic hydroprocessing in supercritical methanol with Cu/CuMgAlOx catalyst. The yield of monomers reached 37.76C% with 240 min at 300 °C. Cyclohexanols were identified as the major monomeric products, indicating the occurrence of hydrodeoxygenation and hydrogenation. GPC, quant. 13C NMR, HSQC NMR, and HMBC NMR analyses evidenced the depolymerization of SL and upgrading of its derivatives Furthermore, the mechanistic studies were carried out to provide insights to the stubborn linkage cleavages. The degrees of difficulty to break up the three involved linkages obeyed the sequence of β-5 > 4-O-5 > α-O-4. The apparent activating energies (Ea), chemisorption energies (Ec), and bond dissociation energies (BDE) were determined computationally to support the exptl. results from the perspectives of kinetics, chemisorption, and thermodn., resp. This research provides a reliable way for the utilization of SL. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).COA of Formula: C8H10O

Peng, Bing; Wu, Lanyan; Li, Qingzhu; Wang, Qingwei; Li, Kaizhong; Zhou, Zeyan published an article in 2022, the title of the article was Photodegradation of naproxen using CuZnAl-layered double hydroxides as photocatalysts.Application of 93-04-9 And the article contains the following content:

Naproxen (NPX), as a typical pharmaceutical and personal care product (PPCP), is frequently detected in water and is difficult to remove effectively by conventional methods. Layered double hydroxides, as highly efficient photocatalysts, have not been used in photocatalysis of PPCP. In this study, CuZnAl-layered double hydroxide (CuZnAl-LDH) was prepared and its performance in the photocatalytic degradation of NPX under UV light illumination was investigated. The results indicated that the NPX photodegradation is considerably enhanced by CuZnAl-LDH with an efficiency of 98.25% in the optimal conditions, which was obviously more than that under pure light condition (efficiency less than 30%). In addition, the CuZnAl-LDH photocatalyst exhibited superior photocatalytic stability confirmed by the analyses of the catalyst structure, morphol., and cycle experiments Moreover, by the comparison of optical properties of ZnAl-LDH and CuZnAl-LDH, it was found that Cu2+ can broaden light absorption and facilitate the separation of photogenerated charges electrons (e-) and holes (h+), and in the CuZnAl-LDH system, the formation mechanism of active species complies with the mechanisms of the ligand-to-metal charge transfer (LMCT) from the 2p orbital of oxygen to the 3d orbital of M2+ and of the d-d transition of Cu2+ ions of the CuO6 unit. Besides, ESR and scavenging tests revealed that the photocatalytic process was enhanced by the synergistic effect of h+, O2-, and OH, which displayed the sequence of h+ > .O2- > .OH. Finally, the intermediate products were identified by LCMS-IT-TOF, and no intermediates with greater toxicity than NPX were produced. The possible degradation pathway of NPX was proposed involving the decarboxylation, demethylation, and hydroxylation reactions and ring-opening based on intermediates. These results are expected to provide new data on the photodegradation of naproxen. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Application of 93-04-9

Li, Fei; Zang, Mingsong; Liu, Shengda; Li, Xiumei; Jiang, Xiaojia; Tian, Ruizhen; Luo, Quan; Hou, Chunxi; Xu, Jiayun; Liu, Junqiu published an article in 2021, the title of the article was Difunctionalized pillar[5]arene-based polymer nanosheets for photodynamic therapy of Staphylococcus aureus infection.Recommanded Product: 150-78-7 And the article contains the following content:

Bacterial infections pose severe threats to global public health security. Developing antibacterial agents with both high efficiency and safety to handle this problem has become a top priority. Here, highly stable and effective polymer nanosheets have been constructed by the covalent co-assembly of a pillar[5]arene derivative and metalloporphyrin for photodynamic antibacterial therapy (PDAT). The monolayer nanosheets are strongly pos. charged and thus capable of binding with Staphylococcus aureus (SA) through electrostatic interactions. Addnl., the nanosheets can be activated to generate reactive oxygen species (ROS) under white-light irradiation, and exhibit satisfactory antibacterial performance towards SA. More importantly, cell viability assays demonstrate that the nanosheets show little to no cytotoxicity impact on mammalian cells even when the concentrations are much higher than those employed in the antibacterial studies. The above results suggest that the polymer nanosheets could be an effective antibacterial agent to overcome bacterial infections and hold a broad range of potential applications in real life.

And the article contained the following:

The precise construction of the high-order mech. interlocked mols. (MIMs) with well-defined topol. arrangements of multiple mech. interlocked units has been a great challenge. Herein, we present the first successful preparation of a new family of daisy chain dendrimers, in which the individual [c2]daisy chain rotaxane units serve as the branches of dendrimer skeleton. In particular, the third-generation daisy chain dendrimer with 21 [c2]daisy chain rotaxane moieties was realized, which might be among the most complicated discrete high-order MIMs comprised of multiple [c2]daisy chain rotaxane units. Interestingly, such unique topol. arrangements of multiple stimuli-responsive [c2]daisy chain rotaxanes endowed the resultant daisy chain dendrimers controllable and reversible nanoscale dimension modulation through the collective and amplified extension/contraction of each [c2]daisy chain rotaxane branch upon the addition of acetate anions or DMSO mols. as external stimulus. Furthermore, on the basis of such an intriguing size switching feature of daisy chain dendrimers, dynamic composite polymer films were constructed through the incorporation of daisy chain dendrimers into polymer films, which could undergo fast, reversible, and controllable shape transformations when DMSO mols. were employed as stimulus. The successful merging of [c2]daisy chain rotaxanes and dendrimers described herein provides not only a brand-new type of high-order mech. interlocked systems with well-defined topol. arrangements of [c2]daisy chain rotaxanes, but also a successful and practical approach toward the construction of supramol. dynamic materials.

Beni, Ryan; Boadi, William; Karim, Kaleh; Alnakhli, Jawzah; Alhamed, Samiyah published an article in 2019, the title of the article was Synthesis and antiproliferative activities of triphenylmethanol conjugates of leuprorelin.SDS of cas: 321-28-8 And the article contains the following content:

Leuprorelin (LEP) is an FDA drug for breast cancer and prostate cancer treatment. There are several reported adverse effects such as transient hypertension, excessive salivation, and increased dysuria during treatment with LEP. In this study, the efficacy and toxicity of LEP were modified by using a drug delivery system to adjust the physicochem. properties. In this regard, Leuprorelin conjugates of triphenylmethanol derivatives (TPMs) were synthesized as prodrugs. Comparative antiproliferative assays showed that LEP-TPMs conjugates had significantly higher antiproliferative activities than the corresponding non-covalent phys. mixtures of the TPMs and LEP against human invasive ductal carcinoma (BT549), human prostate carcinoma (PC3), human lung cancer (A549) and mouse pre-adipocytes (3T3-L1) cells.

Wang, Xia; Xing, Yue; Su, Jing; Wang, Changsheng; Wang, Zishi; Yu, Yinghui; Xu, Hongliang; Ma, DongSheng published an article in 2021, the title of the article was Synthesis of two new naphthalene-containing compounds and their bindings to human serum albumin.Related Products of 91-16-7 And the article contains the following content:

Two naphthalene-containing compounds, 4-hydroxy-6,7-dimethoxy-1-(4-(trifluoromethyl)phenyl)-2-naphthoic acid (A) and 4-hydroxy-6,7-dimethoxy-1-phenyl-2-naphthoic acid (B), were prepared by several steps. Their bindings to human serum albumin (HSA) were studied by UV-visible (UV-vis) absorption, fluorescence, synchronous fluorescence, three-dimensional fluorescence, CD (CD) spectroscopies and mol. docking. The crystal data of these compounds show the structure of the compounds The results show that the mechanism of the interaction between compound A and HSA is mixed-quenching (both dynamic and static quenching), while that of compound B and HSA is static quenching. The number of binding sites, binding constants and binding distance (r) were obtained. The interaction processes are spontaneous. A mainly interacts with HSA through typical hydrophobic interaction, and B binds to HSA mainly by the hydrogen bonds and van der Waals forces. The conformation of HSA changes slightly after the addition of the compounds Besides, mol. docking method was used to study the interaction details between the compounds and HSA. This is helpful to understand the absorption and metabolism of these two compounds in the body, and provides a basis for designing naphthalene-containing drugs. Communicated by Ramaswamy H.

On November 17, 2021, Zhai, Binbin; Huang, Rongrong; Tang, Jiaqi; Li, Min; Yang, Jinglun; Wang, Gang; Liu, Kaiqiang; Fang, Yu published an article.Category: ethers-buliding-blocks The title of the article was Film Nanoarchitectonics of Pillar[5]arene for High-Performance Fluorescent Sensing: a Proof-of-Concept Study. And the article contained the following:

Substrates play crucial roles for the sensing performances of fluorescent films owing to their effect on the formation of a fluorescent adlayer. However, no such film has been developed through synthesizing a substrate with a defined structure. We herein report a kind of self-standing, uniform, and thickness tunable pillar[5]arene-based nanofilms to serve as substrates for fabricating fluorescent sensing films. In comparison with a glass plate, the pillar[5]arene-based nanofilms can ensure spatial and electronic isolation of immobilized fluorophores and circumvent aggregation-caused quenching in a film state. For conceptual proof, a formic acid fluorescent sensing film was developed through simple loading of a fluorophore, a 4-azetidine-1,8-naphthalimide derivative of cholesterol (NA-Ch), onto the prepared nanofilm. Sensing performance studies demonstrated that the fluorescent film showed a sensitive, fast, and highly selective response to formic acid in air with a detection limit of lower than 2.8 mg m-3 and a response time of less than 3 s. Moreover, the sensing is fully reversible and highly repeatable. Further studies showed that the film sensor can be used for fast determination of methanol acidity via vapor sampling. Clearly, innovation of substrates with defined structures can be taken as an effective and efficient way to develop new sensing films via combination with known fluorophores. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Category: ethers-buliding-blocks
