Pd-catalyzed amidation of 1,3-diketones with CO and azides via a nitrene intermediate was written by Gu, Zheng-Yang;Chen, Jie;Xia, Ji-Bao. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2020.Reference of 3438-16-2 This article mentions the following:

An efficient Pd-catalyzed amidation of 1,3-diketones has been developed using carbon monoxide and organic azides. This reaction provides a step-economic approach to produce β-ketoamides from readily available compounds under mild ligand-, oxidant-, and base-free conditions. The mechanistic studies showed that the reaction occurred through an in situ generated isocyanate intermediate. In the experiment, the researchers used many compounds, for example, 5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2Reference of 3438-16-2).

5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Reference of 3438-16-2

Solid-Phase Synthesis of Chlorofusin Analogues was written by Woon, Esther C. Y.;Arcieri, Mariangela;Wilderspin, Andrew F.;Malkinson, John P.;Searcey, Mark. And the article was included in Journal of Organic Chemistry in 2007.Name: 5-Chloro-2-methoxybenzoic acid This article mentions the following:

The authors have efficiently synthesized two series of chlorofusin analogs, one bearing varying chromophores and the other with various amino acid substitutions in the cyclic peptide. These peptides were prepared via solid-phase methods using a strategy involving side-chain immobilization, on-resin cyclization, and postcyclization modification. The success of these syntheses demonstrates the broad utility of the method. Both series of analogs were evaluated for their inhibitory activity against the p53/MDM2 interaction but were shown to be inactive in the concentration range tested. This suggests that the full chromophore structure may be required for activity. In the experiment, the researchers used many compounds, for example, 5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2Name: 5-Chloro-2-methoxybenzoic acid).

5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Name: 5-Chloro-2-methoxybenzoic acid

Development, synthesis, and biological evaluation of sulfonyl-α-L-amino acids as potential anti-Helicobacter pylori and IMPDH inhibitors was written by Galal, Alaaeldin M. F.;Mohamed, Hanaa S.;Abdel-Aziz, Marwa M.;Hanna, Atef G.. And the article was included in Archiv der Pharmazie (Weinheim, Germany) in 2021.Application In Synthesis of 5-Chloro-2-methoxybenzoic acid This article mentions the following:

IMP dehydrogenase (IMPDH) catalyzes a crucial step in the biosynthesis of DNA and RNA, and it has been exploited as a promising target for antimicrobial therapy. The present study discusses the development and synthesis of a series of sulfonyl-α-L-amino acids coupled with the anisamide scaffold and evaluates their activities as anti-Helicobacter pylori and IMPDH inhibitors. Twenty derivatives were synthesized and their structures were established by high-resolution mass spectrometry and ¹H and ¹³C NMR measurements. Four compounds (I) (R¹ = L-Val, L-Leu, L-Ile, L-Trp) were found to be the most potent and selective mols. in the series with min. inhibitory concentration (MIC) values <17μM, which were selected to test their inhibitory activities against HpIMPDH and human (h)IMPDH2 enzymes. In all tests, amoxicillin and clarithromycin were used as reference drugs. Compounds I (R¹ = L-Val, L-Leu) were found to have a promising activity against the HpIMPDH enzyme, with IC₅₀ = 2.42 and 2.56μM, resp. Moreover, the four compounds were found to be less active and safer against hIMPDH2 than the reference drugs, with IC₅₀ > 17.17μM, which makes sure that their selectivity is toward HpIMPDH and reverse to that of amoxicillin and clarithromycin. Also, the synergistic antibacterial activity of compounds I (R¹ = L-Val, L-Leu) amoxicillin, and clarithromycin was investigated in vitro. The combination of amoxicillin/compound I (R¹ = L-Val) (2:1 by weight) exhibited a significant antibacterial activity against H. pylori, with MIC = 0.12μg/mL. The mol. docking study and ADMET anal. of the most active compounds were used to elucidate the mode-of-action mechanism. In the experiment, the researchers used many compounds, for example, 5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2Application In Synthesis of 5-Chloro-2-methoxybenzoic acid).

5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Application In Synthesis of 5-Chloro-2-methoxybenzoic acid

Multifunctional coatings with broadband antireflective, durable, photocatalytic, and self-cleaning properties can enhance photovoltaic (PV) power generation by reducing the cleaning frequency and surface light reflection of PV modules. However, such coatings must be cost-effective and maintain their functional integrity under harsh outdoor environmental conditions. In this study, bayberry-like SiO₂ @TiO₂ nanoparticles were prepared by a sol-gel method, and their synthesis procedure and SiO₂/TiO₂ sol volume ratio were optimized based on the refractive index, transmittance distribution, and methylene blue degradation rate. Afterwards, three-layer gradient refractive index broadband antireflective coatings (TGBA) of the optimized SiO₂ @TiO₂ nanoparticles were simulated theor. and systematically characterized by various exptl. techniques. The average transmittance of TGBA-coated glass was 8.93% (380-1800 nm) higher than that of undipped glass, and the photocatalytic performance of TGBA was verified by studying methylene blue photodegradation The self-cleaning performance of TGBA was assessed by outdoor exposure, multi-cycle UV irradiation, and dark storage. The durability of TGBA was evaluated by conducting hardness measurements, abrasion testing, thermal cycling, and damp heat tests. The external quantum efficiency and J-V curves of TGBA-coated PV mini-modules revealed that their short-circuit current densities and power conversion efficiencies were substantially higher than those of undipped modules. The proposed multifunctional coatings can enhance PV power generation in harsh environments.

And the article was included in Journal of Enzyme Inhibition and Medicinal Chemistry in 2021.Electric Literature of C8H9ClO4S This article mentions the following:

Nonsteroidal aromatase inhibitors (NSAIs) are well-established drugs for the therapy of breast cancer. However, they display some serious side effects, and their efficacy can be compromised by the development of chemoresistance. Previously, we have reported different indazole-based carbamates and piperidine-sulfonamides as potent aromatase inhibitors. Starting from the most promising compounds, here we have synthesized new indazole and triazole derivatives and evaluated their biol. activity as potential dual agents, targeting both the aromatase and the inducible nitric oxide synthase, being this last dysregulated in breast cancer. Furthermore, selected compounds were evaluated as antiproliferative and cytotoxic agents in the MCF-7 cell line. Moreover, considering the therapeutic diversity of azole-based compounds, all the synthesized compounds were also evaluated as antifungals on different Candida strains. A docking study, as well as mol. dynamics simulation, were carried out to shed light on the binding mode of the most interesting compound into the different target enzymes catalytic sites.

Development of polyester filters with polymer nanocomposite active layer for effective dye filtration was written by Pasichnyk, Mariia;Gaalova, Jana;Minarik, Peter;Vaclavikova, Miroslava;Melnyk, Inna. And the article was included in Scientific Reports in 2022.Product Details of 61-73-4 This article mentions the following:

Organic dyes such as methyl orange (MO) and methylene blue (MB) are widely used in different industries and have become one of the leading emerging water contaminants. The purpose of the current research is to develop new polymer nanocomposite filters for the effective elimination of the dyes, which are non-biodegradable and not efficiently removed by traditional treatment methods. New padded and covered filters were produced applying polystyrene-acrylic/ZnO nanocomposite on the polyester surface by blade coating and one-bath pad methods. Principal results determined by SEM anal. confirm that functionalized layer can create unprecedented function of filter textile material depending on the way of treatment. Due to the modification, the surface area increased from 5.9 for untreated polyester to 85.2 (padded), 44.6 (covered) m²/g. The measured pore size of produced filters is around 3.4 nm, which corresponds to the mesoporous structure. Our study reported effective filters with the rate of MB and MO removal efficiencies up to 60%. Moreover, a colorless reduced form of MB-leuco-methylene blue (LMB) could be created. The functionalized layer of the developed filters through hydrogen bonding between the -OH groups of styrene-acrylic mols. and the -N(CH₃)₂ groups on LMB can stabilize LMB.
