And the article was included in Journal of Medicinal Chemistry in 2014.Synthetic Route of C8H6BrFO2 This article mentions the following:

NMDA receptors are tetrameric complexes composed of GluN1 and GluN2A-D subunits that mediate a slow Ca²⁺-permeable component of excitatory synaptic transmission. NMDA receptors have been implicated in a wide range of neurol. diseases and thus represent an important therapeutic target. We herein describe a novel series of pyrrolidinones, e.g., I, that selectively potentiate only NMDA receptors that contain the GluN2C subunit. The most active analogs tested were over 100-fold selective for recombinant GluN2C-containing receptors over GluN2A/B/D-containing NMDA receptors as well as AMPA and kainate receptors. This series represents the first class of allosteric potentiators that are selective for diheteromeric GluN2C-containing NMDA receptors. In the experiment, the researchers used many compounds, for example, Methyl 4-bromo-2-fluorobenzoate (cas: 179232-29-2Synthetic Route of C8H6BrFO2).

Methyl 4-bromo-2-fluorobenzoate (cas: 179232-29-2) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Synthetic Route of C8H6BrFO2

Discovery of potent, non-carbonyl inhibitors of fatty acid amide hydrolase (FAAH) was written by Gowlugari, Sumithra;DeFalco, Jeff;Nguyen, Margaret T.;Kaub, Carl;Chi, Candace;Duncton, Matthew A. J.;Emerling, Daniel E.;Kelly, Michael G.;Kincaid, John;Vincent, Fabien. And the article was included in MedChemComm in 2012.Electric Literature of C9H11BrO This article mentions the following:

Fatty acid amide hydrolase (FAAH) inhibition is a promising target for the treatment of pain, anxiety and depression. The vast majority of FAAH inhibitors contain an electrophilic moiety and are known to react covalently with the enzyme. Herein we present the discovery of potent inhibitors, such as RN-450 29, which are based upon a novel tetrahydropyridopyridine scaffold lacking an obvious electrophilic site, and which appear to inhibit FAAH in a reversible and non-covalent manner. In the experiment, the researchers used many compounds, for example, 1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0Electric Literature of C9H11BrO).

1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Electric Literature of C9H11BrO

Copper-Catalyzed Trifluoromethylation of Alkyl Bromides was written by Kornfilt, David J. P.;MacMillan, David W. C.. And the article was included in Journal of the American Chemical Society in 2019.Name: 2-(Bromomethyl)-1,3-dimethylbenzene This article mentions the following:

Copper oxidative addition into organohalides is a challenging two-electron process. In contrast, formal oxidative addition of copper to C_sp² carbon-bromine bonds can be accomplished by employing latent silyl radicals under photoredox conditions. This novel paradigm for copper oxidative addition has now been applied to a Cu-catalyzed cross-coupling of C_sp³-bromides. Specifically, a copper/photoredox dual catalytic system for the coupling of alkyl bromides with trifluoromethyl groups is presented. This operationally simple and robust protocol successfully converts a variety of alkyl, allyl, benzyl, and heterobenzyl bromides into the corresponding alkyl trifluoromethanes. In the experiment, the researchers used many compounds, for example, 2-(Bromomethyl)-1,3-dimethylbenzene (cas: 83902-02-7Name: 2-(Bromomethyl)-1,3-dimethylbenzene).

2-(Bromomethyl)-1,3-dimethylbenzene (cas: 83902-02-7) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Name: 2-(Bromomethyl)-1,3-dimethylbenzene

And the article was included in Food Control in 2022.Category: bromides-buliding-blocks This article mentions the following:

Propiconazole is a widely used fungicide in agricultural production, but it poses risks to human health. Here, an indirect competitive ELISA (ic-ELISA) based on a monoclonal antibody (mAb) was established to detect propiconazole residues. Three haptens of propiconazole were designed and synthesized to prepare antigens. Ten mAbs were obtained using hapten B (5-(4-(2-((1H-1,2,4-triazol-1-yl)methyl)-4-propyl-1,3-dioxolan-2-yl)-3-chlorophenyl) pentanoic acid). The ic-ELISA based on the combination of mAb 2G2E12 and hapten B-ovalbumin (coating antigen) showed the highest sensitivity. After optimization, the 50% inhibition concentration, limit of detection and linear range of the ic-ELISA were 2.33 μg/L, 0.26 μg/L and 0.26-21.28 μg/L, resp. The cross-reactivities for the analogs of propiconazole were ≤1.9%. The average recoveries of the spiked samples were 75.7%-117.0% with relative standard deviations of ≤9.4%. The results of the ic-ELISA were consistent with those of gas chromatog.-mass spectrometry in the anal. of blind samples. Therefore, we provide an alternative tool for the accurate and reliable determination of propiconazole. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5Category: bromides-buliding-blocks).

And the article was included in Journal of Organic Chemistry in 2022.HPLC of Formula: 128-08-5 This article mentions the following:

A series of 2-(isoquinol-1-yl)pyrrole-boron complexes possessing (hetero)aryl substituents on the pyrrole and/or isoquinoline moiety were prepared These compounds exhibited the fluorescence emission character in both solution and solid state. In most cases, the large Stokes shift and high fluorescence quantum yield in the solution were compatible. Furthermore, the structural diversity allowed the precise tuning of emitting colors from light blue to red with strong emission intensity. The present paper describes their comprehensive optical characteristics dependent on the type and position of the substituted aryl groups by the exptl. and computational studies. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5HPLC of Formula: 128-08-5).

1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5).

Understanding of Molecular Substructures that Contribute to hERG K⁺ Channel Blockade: Synthesis and Biological Evaluation of E-4031 Analogues was written by Vilums, Maris;Overman, Jeroen;Klaasse, Elisabeth;Scheel, Olaf;Brussee, Johannes;Ijzerman, Adriaan P.. And the article was included in ChemMedChem in 2012.SDS of cas: 14425-64-0 This article mentions the following:

Cardiotoxicity is a common side effect of a large variety of drugs that is often caused by off-target human ether-a-go-go-related gene (hERG) potassium channel blockade. In this study, we designed and synthesized a series of derivatives of the class III antiarrhythmic agent E-4031. These compounds where evaluated in a radioligand binding assay and automated patch clamp assay to establish structure-activity relationships (SAR) for their inhibition of the hERG K⁺ channel. Structural modifications of E-4031 were made by altering the peripheral aromatic moieties with a series of distinct substituents. Addnl., we synthesized several derivatives with a quaternary nitrogen and modified the center of the mol. by introduction of an addnl. nitrogen and deletion of the carbonyl oxygen. Some modifications caused a great increase in affinity for the hERG K⁺ channel, while other seemingly minor changes led to a strongly diminished affinity. Structures with quaternary amines carrying an addnl. aromatic moiety were found to be highly active in radioligand binding assay. A decrease in affinity was achieved by introducing an amide functionality in the central scaffold without directly interfering with the pK_a of the essential basic amine. The knowledge gained from this study could be used in early stages of drug discovery and drug development to avoid or circumvent hERG K⁺ channel blockade, thereby reducing the risk of cardiotoxicity, related arrhythmias and sudden death.

Introducing a uniquely substituted Ph sulfone into a series of biphenyl imidazole liver X receptor (LXR) agonists afforded a dramatic potency improvement for induction of ATP binding cassette transporters, ABCA1 and ABCG1, in human whole blood. The agonist series demonstrated robust LXRβ activity (>70%) with low partial LXRα agonist activity (<25%) in cell assays, providing a window between desired blood cell ABCG1 gene induction in cynomolgus monkeys and modest elevation of plasma triglycerides for agonist I. The addition of polarity to the Ph sulfone also reduced binding to the plasma protein, human α-1-acid glycoprotein. Agonist I was selected for clin. development based on the favorable combination of in vitro properties, excellent pharmacokinetic parameters and a favorable lipid profile. In the experiment, the researchers used many compounds, for example, Ethyl 4-bromo-2-fluorobenzoate (cas: 474709-71-2Synthetic Route of C9H8BrFO2).
