The article was titled 《Carbazole based ionic small molecule emitter for non-doped light-emitting electrochemical cells》. The information in the text is summarized as follows:

Great efforts have been made to develop blue emitting organic small mols. for light-emitting electrochem. cells. Herein, blue emitting CPC (CarPhenCar) was synthesized and its emissive properties were studied. CPC exhibits blue fluorescence in toluene solution as well as in solid thin-films. CPC exhibits good thermal and electrochem. stabilities. Application of CPC mol. in solution processed light-emitting electrochem. cells resulted blue emission centered at 485 nm with brightness of 454 cd/m2, current efficiencies of 1.33 cd/A and external quantum efficiencies of 1.76%. These results adequately demonstrate the practicability of tuning the emission color of phenothiazine derivative into blue region.

In 2018,Martin, Sara E.; Nguyen, Catherine M.; Basaraba, Randall J.; Melander, Christian published 《Analogue synthesis reveals decoupling of antibiofilm and β-lactam potentiation activities of a lead 2-aminoimidazole adjuvant against Mycobacterium smegmatis》.Chemical Biology & Drug Design published the findings.Product Details of 7720-39-0 The information in the text is summarized as follows:

Biofilm formation is one of the many mechanisms bacteria utilize to survive antibiotic treatment. It has been demonstrated that when Mycobacterium tuberculosis exists in a biofilm in vitro, it expresses phenotypic resistance to antimicrobial drugs. As the in vivo survival of M. tuberculosis following drug treatment is potentially linked to a biofilm-like expression of drug tolerance, it is hypothesized that biofilm dispersion should increase antibiotic susceptibility and reduce the duration of the current antibiotic treatment regimen. Previously, we have identified a 2-aminoimidazole (2-AI) compound capable of dispersing and inhibiting M. tuberculosis and M. smegmatis biofilms in vitro. Addnl., this compound potentiated the activity of carbenicillin against M. tuberculosis and, to a lesser degree, M. smegmatis. Here, we describe a SAR study on this compound evaluating each derivative for biofilm dispersion and β-lactam potentiation capabilities against M. smegmatis. This study identified a compound that improved upon the biofilm dispersion capabilities of the lead compound Interestingly, a different compound was identified with an increased ability to potentiate a subset of β-lactam antibiotics. These compounds indicate that biofilm dispersion and potentiation capabilities may not be associated In the experimental materials used by the author, we found 1H-Imidazol-2-amine(cas: 7720-39-0Product Details of 7720-39-0)

《Zwitterions as novel phase forming components of aqueous biphasic systems》 was written by Basaiahgari, Anusha; Yadav, Sandeep Kumar; Gardas, Ramesh L.. Application of 616-47-7This research focused onZwitterion aqueous biphasic system phase forming component. The article conveys some information:

A novel class of aqueous biphasic systems (ABS) formed by zwitterions (ZI) has been investigated in the present work. A series of water soluble ZIs have been synthesized using triethylamine, N-Methylimidazole, N-Vinylimidazole, pyridine, N-Methylpyrrolidine, N-Ethylpiperidine and 1,4 butane sultone. The synthesized ZIs were explored for their ability to form biphasic systems in combination with aqueous inorganic salt solutions of K3PO4, K2HPO4 and K2CO3. The phase diagrams for all systems have been constructed through cloud point titration method at 298.15 K and atm. pressure. The phase behavior of ZI based ABS have been analyzed to understand the structural effects of ZIs as well as the effect of nature of salt used on the overall phase formation. Further the temperature dependence of the ZI based ABS was also explored by studying the phase behavior at variable temperatures of 298.15, 308.15 and 318.15 K. In order to estimate the applicability of proposed ZI based ABS, extraction experiments have been performed for an alkaloid i.e. caffeine for all synthesized ZIs with K3PO4 and at 298.15 K. ZI based ABS have been found to be capable of single step extraction of caffeine similar to IL based ABS thus providing the possibilities to explore these ZI based ABS as efficient extraction and separation systems.

F.; Vanhoof, Greet; Leonard, Philip M.; Lamers, Marieke B. A. C.; Van Roosbroeck, Yves E. M.; Buijnsters, Peter J. J. A.. Formula: C3H5N3This research focused ontriazolopyrimidine preparation selective PDE2A inhibitor; structure triazolopyrimidine inhibition phosphodiesterase selectivity; pharmacokinetics CYP inhibition BBB permeability triazolopyrimidine; free energy perturbation optimization triazolopyrimidine substituent phosphodiesterase inhibitor; crystal structure triazolopyrimidine complex phosphodiesterase 2A. The article conveys some information:

We describe the hit-to-lead exploration of a [1,2,4]triazolo[1,5-a]pyrimidine phosphodiesterase 2A (PDE2A) inhibitor arising from high-throughput screening. X-ray crystallog. enabled structure-guided design, leading to the identification of preferred substructural components. Further rounds of optimization used relative binding free-energy calculations to prioritize different substituents from the large accessible chem. space. The free-energy perturbation (FEP) calculations were performed for 265 putative PDE2A inhibitors, and 100 compounds were synthesized representing a relatively large prospective application providing unexpectedly active mols. with IC50’s from 2340 to 0.89 nM. Lead compound 46 originating from the FEP calculations showed PDE2A inhibition IC50 of 1.3 ± 0.39 nM, ~100-fold selectivity vs. other PDE enzymes, clean cytochrome P 450 profile, in vivo target occupancy, and promise for further lead optimization.

Product Details of 616-47-7In 2019 ,《Self-assembled structure and dynamics of imidazolium-based protic salts in water solution》 was published in Physical Chemistry Chemical Physics. The article was written by Zhu, Haijin; Vijayaraghavan, R.; MacFarlane, Douglas R.; Forsyth, Maria. The article contains the following contents:

Protic ionic liquids containing cations with long alkyl chains can form self-assembled micelles, vesicles, microemulsions, and lyotropic liquid crystal structures in water, acid water or THF, etc. As a result of this unique property, they are regarded as a novel category of amphiphiles, and are gaining importance in the field of colloid and interface chem. The critical micelle concentration (CMC) of protic salts, e.g., alkyl-ammonium nitrates in water, was found to increase with decreasing chain length. It is generally believed that a long alkyl chain length is essential for the formation of self-assembled structures. So far, no self-assembled structure has been reported for protic ionic liquids with an alkyl chain length of n < 4. This paper reports on the structure and dynamics of two imidazolium based protic organic salts with no alkyl chain or a Me group (n = 1) attached to the cation in water solution, determined through a detailed anal. of NMR spectra and pulsed-field gradient NMR data. We demonstrate that these imidazolium cations with no or a short alkyl chain (n = 1) can form a self-assembled clustering structure in water solution, which has a strong influence on the diffusion behavior of imidazolium mol. ions. It is speculated that this self-assembled structure is likely to be present in other similar solutions of ionic liquids with short alkyl chains.1-Methyl-1H-imidazole(cas: 616-47-7Product Details of 616-47-7) was used in this study.

Atkinson, Ariel J.; Armstrong, Mikayla D.; Eskew, John T.; Coronell, Orlando published their research in Journal of Membrane Science in 2021. The article was titled 《Aminoimidazole reduces fouling and improves membrane performance》.Reference of 1H-Imidazol-2-amine The article contains the following contents:

Biofouling is difficult to control and hinders the performance of membranes in all applications but is of particular concern when natural waters are purified. Fouling, via multiple mechanisms (organic-only, biofouling-only, cell-deposition-only, and organic + biofouling), of a com. available membrane (control) and a corresponding membrane coated with an anti-biofouling 2-aminoimidazole (2-AI membrane) was monitored and characterized during the purification of a natural water. Results show that the amount of bacterial cell deposition and organic fouling was not significantly different between control and 2-AI membranes; however, biofilm formation, concurrent or not with other fouling mechanisms, was significantly inhibited (95-98%, p < 0.001) by the 2-AI membrane. The limited biofilm that formed on the 2-AI membrane was weaker (as indicated by the polysaccharide to protein ratio) and thus presumably easier to remove. The conductivity rejection by the 2-AI and control membranes was not significantly different throughout the 75-h experiments, but the rejection of dissolved organic carbon by biofouled (biofouling-only, cell-deposition-only, and organic + biofouling) 2-AI membranes was statistically higher (10-12%, p = 0.003-0.07). When biofouled, the water permeance of the 2-AI membranes decreased significantly less (p < 0.05) over 75 h than that of the control membranes, whether or not other addnl. types of fouling occurred concurrently. Despite the initially lower water permeances of 2-AI membranes (11% lower on average than controls), the 2-AI membranes outperformed the controls (10-11% higher average water permeance) after biofilm formation occurred. Overall, 2-AI membranes fouled less than controls without detriment to water productivity and solute rejection.

A review. The complexity of the world’s current grand challenges demands interdisciplinary approaches. The education of future scientists must cross the silos of the traditional disciplines; however, there is still a strong reluctance to tear such walls down. Here, we describe an integrative chem. biol. course focused on epigenetics that strives to bring research culture to chem. and biol. Master’s students. The course, which has been successfully implemented for the past two years, combines three modules: lectures, discovery-based research lab, and science communication. Importantly, the outline of our course design could be easily adapted to different fields, improving the synergy between research and teaching in our universities.

In 2018,Journal of Medicinal Chemistry included an article by Norman, Bryan H.; Fisher, Matthew J.; Schiffler, Matthew A.; Kuklish, Steven L.; Hughes, Norman E.; Czeskis, Boris A.; Cassidy, Kenneth C.; Abraham, Trent L.; Alberts, Jeffrey J.; Luffer-Atlas, Debra. Name: 1H-Imidazol-2-amine. The article was titled 《Identification and Mitigation of Reactive Metabolites of 2-Aminoimidazole-Containing Microsomal Prostaglandin E Synthase-1 Inhibitors Terminated Due to Clinical Drug-Induced Liver Injury》. The information in the text is summarized as follows:

Two 2-aminoimidazole-based inhibitors, LY3031207 (1) and LY3023703 (2), of the microsomal prostaglandin E synthase-1 (mPGES-1) enzyme were found to cause drug-induced liver injury (DILI) in humans. We studied imidazole ring substitutions to successfully mitigate reactive metabolite (RM) formation. These studies support the conclusion that RM formation may play a role in the observations of DILI and the consideration of 2-aminoimidazoles as structure alerts, due to the high likelihood of bioactivation to generate RMs. The results came from multiple reactions, including the reaction of 1H-Imidazol-2-amine(cas: 7720-39-0Name: 1H-Imidazol-2-amine)

1H-Imidazol-2-amine(cas: 7720-39-0) belongs to anime. Nitrous acid converts secondary amines (aliphatic or aromatic) to N-nitroso compounds (nitrosamines): R2NH + HNO2 → R2N―NO. Some nitrosamines are potent cancer-inducing substances, and their possible formation is a serious consideration when nitrites, which are salts of nitrous acid, are present in foods or pharmaceutical preparations. Tertiary amines give rise to nitrosamines more slowly; an alkyl group is eliminated as an aldehyde or ketone, along with nitrous oxide, N2O.Name: 1H-Imidazol-2-amine

《Ion Vacancies and Transport in 1-Methylimidazolium Triflate Organic Ionic Plastic Crystal》 was written by Zhu, Haijin; Forsyth, Maria. Quality Control of 1-Methyl-1H-imidazole And the article was included in Journal of Physical Chemistry Letters in 2020. The article conveys some information:

Organic ionic plastic crystals (OIPCs) are an important family of materials that have shown exciting possibilities as solid electrolytes for lithium ion batteries and other electrochem. devices. In this study we demonstrate for the first time that, although the X-ray shows sharp diffraction peaks, both cation and anion clearly exhibit significant ion diffusion in solid phase I. Two phases with ion diffusivities differing by 2 orders of magnitude can be identified. The populations of the cation and anion in both phases are found to be unequal, hinting at the existence of (neg. charged) cation vacancies in the plastic crystal phase and a pos. charged grain boundary phase. These interesting properties of ion vacancies and unequal populations of cation and anion are likely to be ubiquitous in other OIPCs, and it is of paramount importance to be aware of these features to correctly understand the structure-property relationships of this important material family. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazole(cas: 616-47-7Quality Control of 1-Methyl-1H-imidazole)

The author of 《Position-specific 15N isotope analysis in organic molecules: A high-precision 15N NMR method to determine the intramolecular 15N isotope composition and fractionation at natural abundance》 were Joubert, Valentin; Silvestre, Virginie; Lelievre, Maxime; Ladroue, Virginie; Besacier, Fabrice; Akoka, Serge; Remaud, Gerald S.. And the article was published in Magnetic Resonance in Chemistry in 2019. Application of 616-47-7 The author mentioned the following in the article:

The position-specific 15N isotope content in organic mols., at natural abundance, is for the first time determined by using a quant. methodol. based on 15N NMR spectrometry. 15N NMR spectra are obtained by using an adiabatic “”Full-Spectrum”” INEPT sequence in order to make possible 15N NMR experiments with a high signal-to-noise ratio (>500), to reach a precision with a standard deviation below 1% (0.1%). This level of precision is required for observing small changes in 15N content associated to 15N isotope effects. As an illustration, the measurement of an isotopic enrichment factor ε for each 15N isotopomer is presented for 1-methylimidazole induced during a separation process on a silica column. The precision expressed as the long-term repeatability of the methodol. is good enough to evaluate small changes in the 15N isotope contents for a given isotopomer. As observed for 13C, inverse and normal 15N isotope effects occur concomitantly, giving access to new information on the origin of the 15N isotope effects, not detectable by other techniques such as isotope ratio measured by Mass Spectrometry for which bulk (average) values are obtained.
