And the article contained the following:

Abstract: Aberrant activation of c-Met signalling plays a prominent role in cancer development and progression. A series of 12 imidazo [1,2-α] pyridine derivatives bearing 1,2,3-triazole moiety were designed, synthesized and evaluated for c-Met inhibitory potential and anticancer effect. The inhibitory activity of all synthesized compounds against c-Met kinase was evaluated by a homogeneous time-resolved fluorescence (HTRF) assay at the concentration range of 5-25 μM. Derivatives 6d, 6e and 6f bearing Me, tert-Bu and dichloro-Ph moieties on the triazole ring, resp., were the compounds with the highest potential. They significantly inhibited c-Met by 55.3, 53.0 and 51.3%, resp., at the concentration of 25 μM. Synthetic compounds showed antiproliferative effects against lung (EBC-1) and pancreatic cancer cells (AsPc-1, Suit-2 and Mia-PaCa-2) expressing different levels of c-Met, with IC50 values as low as 3.0 μM measured by sulforhodamine B assay. Active derivatives significantly blocked c-Met phosphorylation, inhibited cell growth in three-dimensional spheroid cultures and also induced apoptosis as revealed by Annexin V/propidium iodide flow cytometric assay in AsPc-1 cells. They also inhibited PDGFRA and FLT3 at 25 μM among a panel of 16 kinases. Mol. docking and dynamics simulation studies corroborated the exptl. findings and revealed possible binding modes of the select derivatives with target receptor tyrosine kinases. The results of this study show that some imidazopyridine derivatives bearing 1,2,3-triazole moiety could be promising molecularly targeted anticancer agents against lung and pancreatic cancers. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).Related Products of 574-98-1

On January 15, 2021, El-Sayed, W. N.; Alkabli, J.; Althumayri, Khalid; Elshaarawy, Reda F. M.; Ismail, Lamia A. published an article.SDS of cas: 574-98-1 The title of the article was Azomethine-functionalized task-specific ionic liquid for diversion of toxic metal ions in the aqueous environment into pharmacological nominates. And the article contained the following:

By this work, a new azomethine-supported task-specific ionic liquid (ABIIL) was fabricated based on bis-(butylimidazolium hexafluorophosphate) salicylidene Schiff base. The successful formation of ABIIL was confirmed form its microanal. and spectral results. The excellent aqueous-ethanolic solubility coupled with the high chelating capacity of ABIIL enabled it to act as a multifunctional scavenger for removing of Cu(II) and Fe(III) ions from aqueous environments. Not only has that, but also transformed these toxic ions into promising pharmacol. candidates. ABIIL showed an excellent scavenging efficiency, as it can uptake up to 98.9% and 96.7% of Fe(III) and Cu(II) ions, resp., from aqueous-ethanolic effluents. Besides, it could be easily regenerated and reused for six cycles without significant loss in its efficiency. The scavenging outputs (M-ABIIL) exhibited excellent and broad-spectrum antimicrobial activity, with a slight preference toward fungi than bacteria. Fe-ABIIL is the most potent antimicrobial nominate as revealed from its MIC values (μg/mL): 16.8 (C. albicans) < 18.9 (S. aureus) < 19.5 (A. flavus) < 23.1 (E. coli). Addnl., this complex is more cytotoxic (IC50 3.40 ±0.53 μg/mL) than the clin. anticancer drug (Vinblastine, VB) (IC50 3.79 ± 1.01 μg/mL) toward colon cancer cells (HTC116), whereas it is less cytotoxic (IC50 85.66 ± 1.44 μg/mL) than VB (IC50 57.12 ± 1.95 μg/mL) to normal human cells (HeLa). Thus, ABIIL has great potential for removing toxic Cu(II) and Fe(III) ions from aqueous environments, converting them into chemotherapeutic agents. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).SDS of cas: 574-98-1

Radiolabeled 2-nitroimidazoles have been used for imaging hypoxia. With the aim of developing novel 99mTc radiotracers for imaging hypoxia, four novel 2-nitroimidazole isocyanide derivatives (2a, 2b, 2c, and 2d) were synthesized and radiolabelling was carried out for preparing their corresponding 99mTc complexes. These 99mTc complexes were stable in vitro and could exhibit good hypoxic selectivity. The partition coefficient results indicated that they were hydrophilic, and an evaluation of biodistribution in mice bearing S180 tumors indicated that all of the complexes could accumulate in the tumors. Among them, 99mTc-2c exhibited the highest tumor uptake and tumor/blood and tumor/muscle ratios at 2 h post-injection. Further, single photon emission computed tomog. (SPECT) imaging studies indicated clear accumulation in tumors, suggesting that 99mTc-2c was a promising candidate for hypoxia imaging. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).Formula: C10H8BrNO2

On February 5, 2021, Quiroga-Campano, Cinthia; Gomez-Machuca, Horacio; Moris, Silvana; Pessoa-Mahana, Hernan; Jullian, Carolina; Saitz, Claudio published an article.Product Details of 574-98-1 The title of the article was Synthesis of calix[4]arenes bearing thiosemicarbazone moieties with naphthalene groups: Highly selective turn off/on fluorescent sensor for Cu(II) recognition.. And the article contained the following:

Calix[4]arenes-based fluorescent chemosensors containing thiosemicarbazone as a binding site and naphthalene as a fluorogenic unit in a 1,3-alternate (L1) and cone (L2) conformation, were synthesized and examined for their binding abilities towards anions and cations using different spectroscopic techniques. Both receptors L1 and L2, exhibited an off/on fluorescence behavior due to complex formation with Cu(II). They showed selective recognition of Cu(II) in presence of other cations and anions detecting up to 4.25 μg/L for L1 and 1.58 μg/L for L2, both in acetonitrile. The complexation behavior was studied by 1H NMR and FT-IR spectral anal., indicating that copper interacts with sulfur and with imine nitrogen of the thiosemicarbazone. No major differences in the selectivity and sensitivity were found between calix[4]arene receptors in 1,3-alternate and cone conformation. The 1H NMR spectra indicates that receptor L2 changed its conformation from cone to pinched cone, stiffening the conformation due to interaction of the thiosemicarbazone moiety with copper. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).Product Details of 574-98-1

On August 23, 2021, Xu, Donghan; Zhang, Cuijuan; Zhen, Yihan; Li, Yongdan published an article.Computed Properties of 574-98-1 The title of the article was Ferrocene/Phthalimide Ionic Bipolar Redox-Active Molecule for Symmetric Nonaqueous Redox Flow Batteries. And the article contained the following:

Sym. nonaqueous redox flow batteries (NARFBs) that utilize bipolar redox-active organic mols. (BROMs) provide a facile strategy to mitigate the crossover issue. However, their performance has lagged behind due to the low solubility of organic redox species and poor high-current operations. To address these tech. hurdles, a series of ionic BROMs based on ferrocene (Fc) and phthalimide (Ph) moieties with fast mass and charge-transfer kinetic are synthesized, which show high solubility and ionic conductivity Both computational and exptl. results show that the extended chain length between phthalimide moiety and quaternary nitrogen atom and the acidity of the solvent play a pivotal part in determining the stability of active materials and thus the cycling stability of NARFB. The assembled sym. NARFB shows an open-circuit voltage of 2.04 V, cycling capacity retention of 99.8% per cycle, and energy efficiency of 77.0% over 50 cycles at 20 mA cm-2. Furthermore, the battery yields a peak power d. of 110 mW cm-2 at 90 mA cm-2, which outperforms most NARFBs. This work demonstrates a promising mol. engineering strategy to improve the cycling stability of BROMs and to enable the high-current operation of sym. NARFB. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).Computed Properties of 574-98-1

A.; Otto, Sijbren published an article.HPLC of Formula: 574-98-1 The title of the article was Spontaneous Emergence of Self-Replicating Molecules Containing Nucleobases and Amino Acids. And the article contained the following:

The conditions that led to the formation of the first organisms and the ways that life originates from a lifeless chem. soup are poorly understood. The recent hypothesis of “RNA-peptide coevolution” suggests that the current close relationship between amino acids and nucleobases may well have extended to the origin of life. We now show how the interplay between these compound classes can give rise to new self-replicating mols. using a dynamic combinatorial approach. We report two strategies for the fabrication of chimeric amino acid/nucleobase self-replicating macrocycles capable of exponential growth. The first one relies on mixing nucleobase- and peptide-based building blocks, where the ligation of these two gives rise to highly specific chimeric ring structures. The second one starts from peptide nucleic acid (PNA) building blocks in which nucleobases are already linked to amino acids from the start. While previously reported nucleic acid-based self-replicating systems rely on presynthesis of (short) oligonucleotide sequences, self-replication in the present systems start from units containing only a single nucleobase. Self-replication is accompanied by self-assembly, spontaneously giving rise to an ordered one-dimensional arrangement of nucleobase nanostructures. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).HPLC of Formula: 574-98-1

Bian, Kang-Jie; Li, Yan; Zhang, Kai-Fan; He, Yan; Wu, Tian-Rui; Wang, Cheng-Yu; Wang, Xi-Sheng published an article in 2020, the title of the article was Iron-catalyzed remote functionalization of inert C(sp3)-H bonds of alkenes via 1,n-hydrogen-atom-transfer by C-centered radical relay.Product Details of 574-98-1 And the article contains the following content:

Enabled by 1,n (n = 5, 6)-hydrogen atom transfer (HAT), a most prevalent moiety, alkene, as the precursor to an sp3 C-centered radical to promote selective cleavage of inert C(sp3)-H bonds for the generation of azidotrifluoromethylated mols. I [R1 = Me, n-Bu, Ph, etc.; R2 = H, Me, Et, n-octyl; R1R2 = (CH2)3, (CH2)4, (CH2)2O(CH2)2, etc.; X = C(CO2Et)2, C(CH2OBz)2, NTs] was used. Mild conditions, broad scope and excellent regioselective control (>20 : 1) were observed in the reactions. Deuterium labeling studies disclosed the kinetic characteristics of the transformations and verify a direct 1,n-HAT pathway. The key to this C-centered radical relay was that iron played a dual role as a radical initiator and terminator to incorporate the azide functionality through radical oxidation via azido-ligand-transfer. The methods and the later derivatization promised expeditious synthesis of CF3-containing organic azides, γ-lactam and triazoles that were widely used in designing new fluorescent tags and functional materials.

On June 1, 2022, Liu, Yi; Zhou, Cuihan; Jiang, Meijing; Arndtsen, Bruce A. published an article.Synthetic Route of 574-98-1 The title of the article was Versatile Palladium-Catalyzed Approach to Acyl Fluorides and Carbonylations by Combining Visible Light- and Ligand-Driven Operations. And the article contained the following:

The development of a general palladium-catalyzed carbonylative method to synthesize acyl fluorides RC(O)F (R = n-Bu, cyclohexyl, 4-methylphenyl, pyridin-3-yl, etc.) from aryl, heteroaryl, alkyl, and functionalized organic halides RX was described. Mechanistic anal. suggests that the reaction proceeds via the unique, synergistic combination of visible light photoexcitation of Pd(0) to induce oxidative addition with a ligand-favored reductive elimination. These together create a unidirectional catalytic cycle that is uninhibited by the classical effect of carbon monoxide coordination. Coupling the catalytic formation of acyl fluorides with their subsequent nucleophilic reactions has opened a method to perform carbonylation reactions with unprecedented breadth, including the assembly of highly functionalized carbonyl-containing products.
