Gautam, Rajendra P.; Barile, Christopher J. published their research in Journal of Physical Chemistry C in 2021. The article was titled 《Preparation and Electron-Transfer Properties of Self-Assembled Monolayers of Ferrocene on Carbon Electrodes》.Formula: C6H15NO The article contains the following contents:

In this article, ferrocene is used as a redox-active species to study the electron-transfer properties of self-assembled monolayers (SAMs) on carbon. Glassy carbon electrodes were modified using different compositions of alkyl amine SAMs having various chain lengths and diluent chemistries. An amide coupling reaction was carried out to attach ferrocenecarboxylic acid to the amine-terminated SAMs. We investigated the role defect sites in the SAMs play in effecting electron transfer to the appended ferrocene mols. by modifying the SAMs with ZnO electrodeposits. There is a significant change in the electron-transfer rates as a function of SAM linker length only when the SAM defect sites are blocked with ZnO electrodeposits. These findings imply that defect-driven direct electron transfer occurs on ferrocene-modified SAMs on heterogeneous carbon electrodes in contrast to the alkyl linker tunneling mechanism that is known for well-ordered SAMs on Au electrodes. Finally, we demonstrate that the surface modification protocols used here are amenable to a wide range of carbon electrodes. The experimental process involved the reaction of 6-Aminohexan-1-ol(cas: 4048-33-3Formula: C6H15NO)

6-Aminohexan-1-ol(cas: 4048-33-3) may be used along with glutaric acid to generate poly(ester amide)s with excellent film- and fiber forming properties. It can undergo cyclization over copper supported on γ-alumina and magnesia to form hexahydro-1H-azepine.Formula: C6H15NO

El-Massaoudi, Mohamed; Radi, Smaail; Lamsayah, Morad; Tighadouini, Said; Seraphin, Konan Kouakou; Kouassi, Lazare Kouakou; Garcia, Yann published an article in 2021. The article was titled 《Ultra-fast and highly efficient hybrid material removes Cu(II) from wastewater: Kinetic study and mechanism》, and you may find the article in Journal of Cleaner Production.Computed Properties of C7H9NO2 The information in the text is summarized as follows:

Water pollution by toxic elements represents a significant risk to the environment and human ecosystem, and a number of efforts are developed to find a suitable solution In this work, a new adsorbent based on silica gel as an inert material modified on surface by a pincer ligand was prepared The hybrid material has been synthesized via a simple Schiff base reaction and characterized by several relevant phys. methods. The adsorbent shows an extremely rapid efficiency in removal of copper (less than 8 min) with maximum sorption capacity of 1.90 mmol g-1 and a rapid efficiency for zinc, cadmium and lead (less than 20 min) with adsorption capacities 0.52, 0.49 and 0.43 mmol g-1, resp. A kinetic study shows that the sorption can be described by a pseudo second-order model, and that the process is thermodynamically spontaneous and endothermic. The adsorbent shows a high selectivity to Cu(II) and a great reusability after five adsorption-desorption cycles. Theor., energy dispersive X-ray fluorescence (EDX) and Fourier transform-IR spectroscopy studies demonstrate that the uptake occurs by a coordination reaction between metal ions and the pincer ligand on the surface of the adsorbent. The efficiency of this new hybrid material was confirmed in removal of Cu(II) from real water samples originating from Abidjan Atlantic sea bay, one of the most polluted region in West Africa, as well as from rivers located near Oujda, Morocco.

Keegan, Bradley M.; Catalfano, Kevin C.; Banerjee, Monimoy; Blagg, Brian S. J. published an article in 2022. The article was titled 《Synthesis and Evaluation of Small Molecule Disruptors of the Aha1/Hsp90 Complex for the Reduction of Tau Aggregation》, and you may find the article in ACS Medicinal Chemistry Letters.Reference of 2-Hydroxyphenylboronic acid The information in the text is summarized as follows:

KU-177 was recently shown to disrupt interactions between Hsp90 and Aha1 in vitro. Subsequent studies in recombinant thioflavin T (ThT) assays demonstrated that KU-177 ablates Aha1-driven enhancement of Hsp90-dependent tau aggregation, which was confirmed by TEM. Using KU-177 as a lead compound, derivatives of KU-177 were synthesized and evaluated for their ability to disrupt Aha1/Hsp90 interactions and inhibit P301L tau aggregation. Preliminary structure-activity relationships were revealed, which led to the identification of a new lead compound that contains a cis-like amide bond. The new lead compounds retain the ability to disrupt Aha1/Hsp90 interactions in SH-SY5Y and SK-BR-3 cells without direct inhibition of Hsp90, providing a new scaffold for subsequent drug discovery efforts. The results came from multiple reactions, including the reaction of 2-Hydroxyphenylboronic acid(cas: 89466-08-0Reference of 2-Hydroxyphenylboronic acid)

In 2022,Jud, Wolfgang; Salazar, Chase A.; Imbrogno, Joseph; Verghese, Jenson; Guinness, Steven M.; Desrosiers, Jean-Nicolas; Kappe, C. Oliver; Cantillo, David published an article in Organic Process Research & Development. The title of the article was 《Electrochemical Oxidation of Alcohols Using Nickel Oxide Hydroxide as Heterogeneous Electrocatalyst in Batch and Continuous Flow》.Recommanded Product: 3-Pyridinemethanol The author mentioned the following in the article:

An electrochem. method was developed for a mediated oxidation of primary alcs. to carboxylic acids. The method is compatible with a variety of alcs. bearing N-containing heterocycles in undivided batch and flow modes. The use of a heterogeneous NiOOH electron-proton transfer mediator avoids the need for homogeneous catalysts that contribute to more unit operations during downstream purging and increased process mass intensity. To demonstrate the applicability of this method for continuous processing, a single-pass flow electrochem. oxidation of nicotinyl alc. to nicotinic acid is demonstrated with a 77% isolated yield. The NiOOH-coated anodes show no reduction in catalysis efficiency over 12 h, and minimal Ni metal leaching (22.3μg per L) is observed The experimental process involved the reaction of 3-Pyridinemethanol(cas: 100-55-0Recommanded Product: 3-Pyridinemethanol)

3-Pyridinemethanol(cas: 100-55-0) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Recommanded Product: 3-Pyridinemethanol

Name: 3-Aminopropan-1-olIn 2019 ,《New Insights and Assessment of Primary Alkanolamine/Sulfolane Biphasic Solutions for Post-combustion CO2 Capture: Absorption, Desorption, Phase Separation, and Technological Process》 appeared in Industrial & Engineering Chemistry Research. The author of the article were Liu, Sen; Ling, Hao; Lv, Juan; Gao, Hongxia; Na, Yanqing; Liang, Zhiwu. The article conveys some information:

Surprisingly, sulfolane was determined to be a universal phase splitting solvent in a serial aqueous primary alkanolamine solution for CO2 removal, where carbamate and hydrophilic amine reaction product can be the key factor to trigger CO2 phase change; the phase change can also significantly affect CO2 absorption performance. To comprehensively understand the phase change effect on absorption, stripping, and phase separation performance of primary alkanolamine solution for CO2 capture, a monoethanolamine/sulfolane-based solution was chosen as typical biphasic system. Exptl. results showed phase change can dramatically decrease absorption rate and lead to less CO2 capacity in an absorption process. The MEA-enriched separated solution can substantially decrease energy consumption for CO2 stripping, but exorbitant MEA concentration can significantly reduce CO2 removal efficiency in a quasi absorption/desorption cycle. The MEA/sulfolane emulsion solution phase separation rate can be improved by increasing temperature; fortunately, increasing temperature had a smaller effect on the miscible solubility of MEA and sulfolane in the two separated phases. Considering the absorption rate, energy consumption, and phase separation rate, a new technol. process was proposed for CO2 capture using a primary alkanolamine/sulfolane-based solution to achieve relatively high CO2 removal efficiency and conserve energy. The experimental process involved the reaction of 3-Aminopropan-1-ol(cas: 156-87-6Name: 3-Aminopropan-1-ol)

3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime.

Application In Synthesis of 2,6-PyridinedimethanolIn 2020 ,《Design, synthesis, and biological characterization of a new class of symmetrical polyamine-based small molecule CXCR4 antagonists》 appeared in European Journal of Medicinal Chemistry. The author of the article were Fang, Xiong; Meng, Qian; Zhang, Huijun; Liang, Boqiang; Zhu, Siyu; Wang, Juan; Zhang, Chaozai; Huang, Lina S.; Zhang, Xingquan; Schooley, Robert T.; An, Jing; Xu, Yan; Huang, Ziwei. The article conveys some information:

CXCR4, a well-studied coreceptor of human immunodeficiency virus type 1 (HIV-1) entry, recognizes its cognate ligand SDF-1α (also named CXCL12) which plays many important roles, including regulating immune cells, controlling hematopoietic stem cells, and directing cancer cells migration. These pleiotropic roles make CXCR4 an attractive target to mitigate human disorders. Here a new class of sym. polyamines was designed and synthesized as potential small mol. CXCR4 antagonists. Among them, a representative compound 21 (namely HF50731) showed strong CXCR4 binding affinity (mean IC50 = 19.8 nM) in the CXCR4 competitive binding assay. Furthermore, compound 21 significantly inhibited SDF-1α-induced calcium mobilization and cell migration, and blocked HIV-1 infection via antagonizing CXCR4 coreceptor function. The structure-activity relationship anal., site-directed mutagenesis, and mol. docking were conducted to further elucidate the binding mode of compound 21, suggesting that compound 21 could primarily occupy the minor subpocket of CXCR4 and partially bind in the major subpocket by interacting with residues W94, D97, D171, and E288. Our studies provide not only new insights for the fragment-based design of small mol. CXCR4 antagonists for clin. applications, but also a new and effective mol. probe for CXCR4-targeting biol. studies. The results came from multiple reactions, including the reaction of 2,6-Pyridinedimethanol(cas: 1195-59-1Application In Synthesis of 2,6-Pyridinedimethanol)
