《A highly selective chemical probe for activin receptor-like kinases ALK4 and ALK5》 was written by Hanke, Thomas; Wong, Jong Fu; Berger, Benedict-Tilman; Abdi, Ismahan; Berger, Lena Marie; Tesch, Roberta; Tredup, Claudia; Bullock, Alex N.; Mueller, Susanne; Knapp, Stefan. COA of Formula: C2H4BrNO And the article was included in ACS Chemical Biology in 2020. The article conveys some information:

The transforming growth factor beta-receptor I/activin receptor-like kinase 5 (TGFBR1/ALK5) and its close homolog ALK4 are receptor protein kinases associated with the development of diverse diseases, including cancer, fibrosis, heart diseases, and dysfunctional immune response. Therefore, ALK4/5 are among the most studied kinases, and several inhibitors have been developed. However, current com. available inhibitors either lack selectivity or have not been comprehensively characterized, limiting their value for studying ALK4/5 function in cellular systems. To this end, we report the characterization of the 2-oxo-imidazopyridine, TP-008, a potent chem. probe with dual activity for ALK4 and ALK5 as well as the development of a matching neg. control compound TP-008 has excellent cellular potency and strongly abrogates phosphorylation of the substrate SMAD2 (mothers against decapentaplegic homolog 2). Thus, this chem. probe offers an excellent tool for mechanistic studies on the ALK4/5 signaling pathway and the contribution of these targets to disease. In the part of experimental materials, we found many familiar compounds, such as 2-Bromoacetamide(cas: 683-57-8COA of Formula: C2H4BrNO)

2-Bromoacetamide(cas: 683-57-8) can be used in preparation of (2-carbamoylmethoxy-5-chloro-benzyl)-carbamic acid tert-butyl ester. It was aslo used as precursor to dehydropeptidase I inactivator.COA of Formula: C2H4BrNO

《Surface-Active Ionic-Liquid-Encapsulated Polyoxometalate Nanospheres: Construction, Self-Assembly, Adsorption Behavior, and Application for Dye Removal》 was written by Qi, Lubin; Gong, Yanjun; Fang, Ming; Jia, Zhiwei; Cheng, Ni; Yu, Li. Quality Control of 2-Bromoacetamide And the article was included in ACS Applied Nano Materials in 2020. The article conveys some information:

Preparation of materials which efficiently adsorb environmental pollutants, e.g., non-biodegradable dyes, is urgently demanded. Preparation, characterization, and use of surface-active, ionic liquid-encapsulated polyoxometalates (SAILEP) are reported. These ordered structured hybrid materials were prepared in the aqueous phase by one-pot self-assembly at room temperature They demonstrated a high capacity for rapid cationic dye adsorption. Rhodamine B (RhB) adsorption equilibrium time was only 1 min. These SAILEP materials can also selectively sep. RhB from an eosin Y/RhB mixture Fast, selective adsorption was attributed to electrostatic interactions and high affinity between SAILEP and RhB. An assessment of adsorption isotherms and kinetics indicated dye adsorption followed Langmuir isotherm models and pseudo-second-order kinetics. Self-assembly was assessed by small-angle x-ray scattering, Fourier transform IR, and dynamic light scattering. Results provide addnl. insight on SAILEP hybrid materials, which have great potential for dye decontamination.

《Controlling disinfection byproducts from treated wastewater using adsorption with granular activated carbon: Impact of pre-ozonation and pre-chlorination》 was published in Water Research: X in 2020. These research results belong to Verdugo, Edgard M.; Gifford, Mac; Glover, Caitlin; Cuthbertson, Amy A.; Trenholm, Rebecca A.; Kimura, Susana Y.; Liberatore, Hannah K.; Richardson, Susan D.; Stanford, Benjamin D.; Summers, R. Scott; Dickenson, Eric R. V.. Recommanded Product: 2-Bromoacetamide The article mentions the following:

This study measured chlorine- and chloramine-reactive precursors using formation potential (FP) tests of nine U. S. Environmental Protection Agency (EPA) regulated and 57 unregulated disinfection byproducts (DBPs) in tertiary-filtered wastewater before and after pilot-scale granular activated carbon (GAC) adsorption. Using breakthrough of precursor concentration and of concentration associated calculated cytotoxicity and genotoxicity (by correlating known lethal concentrations reported elsewhere), the performance of three parallel GAC treatment trains were compared against tertiary-filtered wastewater: ozone/GAC, chlorine/GAC, and GAC alone. Results show GAC alone was the primary process, vs. ozone or chlorine alone, to remove the largest fraction of total chlorine- and chloramine-reactive DBP precursors and calculated cytotoxicity and genotoxicity potencies. GAC with pre-ozonation removed the most chlorine- and chloramine-reactive DBP precursors followed by GAC with pre-chlorination and lastly GAC without pre-treatment. GAC with pre-ozonation produced an effluent with cytotoxicity and genotoxicity of DBPs from FP that generally matched that of GAC without pre-oxidation; meanwhile removal of toxicity was greater by GAC with pre-chlorination. The cytotoxicity and genotoxicity of DBPs from FP tests did not scale with DBP concentration; for example, more than 90% of the calculated cytotoxicity resulted from 20% of the DBPs, principally from haloacetaldehydes, haloacetamides, and haloacetonitriles. The calculated cytotoxicity and genotoxicity from DBPs associated with FP-chloramination were at times higher than with FP-chlorination though the concentration of DBPs was five times higher with FP-chlorination. The removal of DBP precursors using GAC based treatment was at least as effective as removal of DOC (except for halonitromethanes for GAC without pre-oxidation and with pre-chlorination), indicating DOC can be used as an indicator for DBP precursor adsorption efficacy. However, the DOC was not a good surrogate for total cytotoxicity and genotoxicity breakthrough behavior, therefore, unregulated DBPs could have neg. health implications that are disconnected from general water quality parameters, such as DOC, and regulated classes of DBPs. Instead, cytotoxicity and genotoxicity correlate with the concentration of specific classes of unregulated DBPs.

《Switching a Xanthine Oxidase Inhibitor to a Dual-Target Antagonist of P2Y1 and P2Y12 as an Oral Antiplatelet Agent with a Wider Therapeutic Window in Rats than Ticagrelor》 was written by Lei, Yu; Zhang, Bing; Liu, Dan; Zhao, Jian; Dai, Xiwen; Gao, Jun; Mao, Qing; Feng, Yao; Zhao, Jiaxing; Lin, Fengwei; Duan, Yulin; Zhang, Yan; Bao, Ziyang; Yang, Yuwei; Mou, Yanhua; Wang, Shaojie. Computed Properties of C2H4BrNOThis research focused onWSJ557 phenylimidazole synthesis antiplatelet SAR metabolism xanthine oxidase purinoceptor. The article conveys some information:

ADP-mediated platelet aggregation is signaled through G protein-coupled receptors P2Y1 and P2Y12 on the platelet. The clin. effectiveness of inhibiting P2Y12 has been well established, and preclin. studies indicated that the inhibition of P2Y1 could provide equivalent antithrombotic efficacy as P2Y12 antagonists and reduce bleeding risks. On the basis of the 2-phenyl-1H-imidazole scaffold of our previously reported xanthine oxidase inhibitor WSJ-557, we first achieved the transition from the xanthine oxidase inhibitors to dual-target antagonists against P2Y1 and P2Y12. We described the structure-activity relationships of the 2-phenyl-1H-imidazole compounds, which led to the identification of the most potent antiplatelet agents, 24w (I) and 25w (II), both showing a rapid onset of action in pharmacokinetic study. Furthermore, the rat model suggested that 24w (I) demonstrated a wider therapeutic window than ticagrelor, displaying equivalent and dose-dependent antithrombotic efficacy with lower blood loss compared to ticagrelor at same oral dose. These results supported that 24w and 25w (II) could be promising drug candidates.

In 2022,Berton, Stefania; Chen, Lu; Liang, Yi Chu; Xu, Zhongliang; Afriyie-Asante, Afrakoma; Rajabalee, Nusrah; Yang, Weibo; Sun, Jim published an article in Cell Chemical Biology. The title of the article was 《A selective PPM1A inhibitor activates autophagy to restrict the survival of Mycobacterium tuberculosis》.Name: 2-Bromoacetamide The author mentioned the following in the article:

Metal-dependent protein phosphatases (PPMs) have essential roles in a variety of cellular processes, including inflammation, proliferation, differentiation, and stress responses, which are intensively investigated in cancer and metabolic diseases. Targeting PPMs to modulate host immunity in response to pathogens is an ambitious proposition. The feasibility of such a strategy is unproven because development of inhibitors against PPMs is challenging and suffers from poor selectivity. Combining a biomimetic modularization strategy with function-oriented synthesis, we design, synthesize and screen more than 500 pseudo-natural products, resulting in the discovery of a potent, selective, and non-cytotoxic small mol. inhibitor for PPM1A, SMIP-30. Inhibition of PPM1A with SMIP-30 or its genetic ablation (ΔPPM1A) activated autophagy through a mechanism dependent on phosphorylation of p62-SQSTM1, which restricted the intracellular survival of Mycobacterium tuberculosis in macrophages and in the lungs of infected mice. SMIP-30 provides proof of concept that PPMs are druggable and promising targets for the development of host-directed therapies against tuberculosis. The results came from multiple reactions, including the reaction of 2-Bromoacetamide(cas: 683-57-8Name: 2-Bromoacetamide)

In 2019,Dalton Transactions included an article by Pradhan, Rabindra N.; Chakraborty, Subhayan; Bharti, Pratibha; Kumar, Janesh; Ghosh, Arindam; Singh, Akhilesh K.. SDS of cas: 683-57-8. The article was titled 《Seven coordinate Co(II) and six coordinate Ni(II) complexes of an aromatic macrocyclic triamide ligand as paraCEST agents for MRI》. The information in the text is summarized as follows:

We are reporting Co(II) and Ni(II) complexes of a pyridine containing aromatic macrocyclic triamide ligand, 3,6,9,15-tetraazabicyclo(9.3.1)pentadeca-1(15),11,13-triene-3,6,9-triacetamide (TPTA), as paramagnetic chem. exchange saturation transfer (paraCEST) MRI contrast agents. The synthesis and characterization of TPTA and its complexes are reported. The solution chem. and solid-state structure of Co(II) and Ni(II) complexes are studied. Crystallog. data show that the [Co(TPTA)]·Cl2·2H2O complex (seven-coordinate, all four N atoms of ring and three amide O atoms) has a distorted pentagonal bipyramidal geometry, however the [Ni(TPTA)Cl]·Cl·0.25H2O complex (six-coordinate, all four N atoms of the ring, one amide O and one chloride ion) adopts a distorted octahedral geometry. Notably the two pendent amide arms are not coordinated in the [Ni(TPTA)Cl]+ complex and one chloride ion fulfils its sixth coordination. The CEST effect of [Co(TPTA)]2+ and [Ni(TPTA)Cl]+ amide protons is observed at 57 ppm and 78 ppm downfield of the bulk water proton resp. in a buffer solution containing 20 mM N-(2-hydroxyethyl)piperazine-N’-ethanesulfonic acid and 100 mM NaCl at pH 7.4 at 37 °C on a 9.4 T NMR spectrometer. The effects of CEST intensity and exchange rate constant with variation of pH of the solution were studied. The CEST effect and exchange rate constant for the amide protons of the [Co(TPTA)]2+ complex have been monitored in HEPES buffer, fetal bovine serum (FBS), rabbit serum and 4% agarose gel (weight/weight). The stability of the [Co(TPTA)]2+ complex in aqueous solution towards oxidation was verified by cyclic voltammetry measurement. The stability of [Co(TPTA)]2+ has further been monitored in the presence of biol. relevant ions including HPO42-, CO32-, and Zn2+ and under acidic conditions.

《Targeted Synthesis of Trimeric Organic-Bromoplumbate Hybrids That Display Intrinsic, Highly Stokes-Shifted, Broadband Emission》 was written by Febriansyah, Benny; Neo, Chong Shern Daniel; Giovanni, David; Srivastava, Shivani; Lekina, Yulia; Koh, Teck Ming; Li, Yongxin; Shen, Ze Xiang; Asta, Mark; Sum, Tze Chien; Mathews, Nripan; England, Jason. Name: 2-Bromoacetamide And the article was included in Chemistry of Materials in 2020. The article conveys some information:

Zero-dimensional (0D) hybrid organic-inorganic lead halides have been shown to display efficient broadband photoluminescence and are, therefore, of significant interest for artificial lighting applications. However, work that investigates the formability of the materials as a function of templating organic cation structure are rare. This severely limits our ability to rationally design new materials displaying specific structural and photophys. properties. With the goal of accessing rare 0D trimeric bromoplumbates, we have systematically varied templating N-alkylpyridinium cations and examined their impact upon inorganic lattice structure. Whereas comparatively short and flexible N-alkyl substituents (Et, 2-hydroxyethyl, and pentyl) yield one-dimensional (1D) inorganic chains, more rigid substituents (benzyl, acetamidyl, and cyanomethyl) afford hybrids composed of lead-bromide face-sharing trimers ([Pb3Br12]6-). Of the rigid substituents studied, benzyl groups were found to enforce the highest level of distortion of the [PbBr6]4- octahedra that comprise their trimeric structures. Upon exposure to ultra-violet (UV) light, N-benzylpyridinium lead-bromide (1)6[Pb3Br12] exhibits a broadband emission, centered at 571 nm, which spans from 400 to 800 nm. More specifically, it displays a large Stokes shift of ca. 1.39 eV and a full width at half maximum (FWHM) of ca. 146 nm. This broadband emission decays with a comparatively long lifetime of 426 ns at room temperature, which increases to 5.8μs at 77 K. The reduced size and dimensionality of its inorganic lattice also results in a photoluminescence quantum yield (at least 10%) that is approx. one order magnitude higher than that of its 1D congeners. Mechanistically, broadband emission in (1)6[Pb3Br12] is believed to originate from triplet excited state(s) obtained from excited-state structural reorganization of the [Pb3Br12]6- moiety. In the experimental materials used by the author, we found 2-Bromoacetamide(cas: 683-57-8Name: 2-Bromoacetamide)

《Design, synthesis, and insecticidal and fungicidal activities of quaternary ammonium salt derivatives of a triazolyphenyl isoxazoline insecticide》 was written by Huang, Shi-sheng; Zhu, Bin-bing; Wang, Kai-hua; Yu, Mo; Wang, Zi-wen; Li, Yongqiang; Liu, Yu-xiu; Zhang, Peng-li; Li, Shou-jun; Li, Ya-ling; Liu, Ai-ling; Wang, Qing-min. Recommanded Product: 683-57-8This research focused ontriazolyphenyl isooxazoline ammonium salt derivative insecticidal fungicidal activity; DP-9; fungicidal activity; insecticidal activity; isoxazoline; quaternary ammonium; structure optimization. The article conveys some information:

Insect pests seriously decrease the yield and quality of agricultural crops. Resistance to commonly used insecticides is increasingly undermining their effectiveness, and therefore the development of agents with novel modes of action is desirable. Isoxazolines are a new class of insecticides that act on γ-aminobutyric acid (GABA) gated chloride channels. In this work, we used the highly active 4-triazolyphenyl isoxazoline DP-9 as a parent structure to design and synthesize a series of quaternary ammonium salt (QAS) derivatives, and we systematically evaluated their insecticidal and antifungal activities. RESULTS : Many of the synthesized QASs exhibit insecticidal activities equivalent to or higher than that of DP-9. In particular, compounds I-31 (93%, 0.00005 mg/L) and I-34 (80%, 0.00001 mg/L) showed insecticidal activities against diamondback moth larvae that were 2-10 times higher than those of fluralaner (70%, 0.0001 mg/L) and DP-9 (80%, 0.0001 mg/L), in addition to showing excellent activities against oriental armyworm, fall armyworm, cotton bollworm, corn borer, and mosquito larvae. Furthermore, all of the synthesized compounds also showed broad-spectrum fungicidal activities. The insecticidal activities of QAS derivatives of DP-9 were the same as or better than the activity of DP-9. Compounds I-31 and I-34 showed better insecticidal activities against diamondback moth larvae than fluralaner and DP-9, and thus are promising new candidates for insecticide research.

The article was written by Rahman, Shofiur; Tomiyasu, Hirotsugu; Wang, Chuan-Zeng; Georghiou, Paris E.; Alodhayb, Abdullah; Carpenter-Warren, Cameron L.; Elsegood, Mark R. J.; Teat, Simon J.; Redshaw, Carl; Yamato, Takehiko. The article contains the following contents:

The synthesis of three new heteroditopic receptors (5a-c) which are based on thiacalix[4]arenes in the 1,3-alternate conformation is reported herein. These new receptors each have two thiourea moieties linking Ph groups, two of which are substituted with electron-withdrawing groups at their para-positions, and at the opposite side of the thiacalix[4]arene cavity, with two 2-pyridylmethyl groups. One example (5a) was also characterized by X-ray crystallog. A limited 1H-NMR and UV-vis anion complexation study was conducted. DFT computational determinations indicated that 5c, which has strongly electron-withdrawing NO2 groups, had the most effective recognition ability towards the selected anions. The binding of Ag+ at the 2-pyridyl moieties, and the binding of the anions at the two thiourea NH groups of the p-substituted phenylthioureido moieties, resp., was also investigated. The appearance of a pos. allosteric effect with receptor 5b was also found using 1H-NMR titration experiments In the part of experimental materials, we found many familiar compounds, such as 2-Bromoacetamide(cas: 683-57-8Recommanded Product: 683-57-8)
