Ma, Kaiqing; Zhang, Mengchen; Wu, Xingkang; Yang, Peng; Yin, Caixia published their research in Bioorganic & Medicinal Chemistry in 2021. The article was titled 《Discovery of a potent β-catenin destabilizer for overcoming the resistance of 5-fluorouracil in colorectal cancer》.Application of 696-59-3 The article contains the following contents:

Wnt/β-catenin signalling is frequently activated in colorectal cancer, in which nuclear β-catenin accumulation contributes to tumor initiation and progression. However, therapeutic agents in clin. use targeting this pathway are lacking. In this report, we describe the synthesis of novel stemona alkaloid analogs and their biol. evaluation, among which compound 3 was identified to efficiently inhibit various CRC cells, including 5-fluorouracil-resistant CRC cells. Mechanistically, this study revealed that compound 3 reduced the protein level of β-catenin without affecting its mRNA level, which suggests an alternative mechanism for β-catenin degradation The expression of downstream proteins, including c-myc, survivin, and cyclin D1, was also significantly inhibited, even in Wnt-activated CRC cells. Briefly, our data highlight the potential of compound 3 as a destabilizer of β-catenin for the treatment of CRC patients. In addition to this study using 2,5-Dimethoxytetrahydrofuran, there are many other studies that have used 2,5-Dimethoxytetrahydrofuran(cas: 696-59-3Application of 696-59-3) was used in this study.

And the article was published in Turkish Journal of Chemistry in 2019. Quality Control of 2,5-Dimethoxytetrahydrofuran The author mentioned the following in the article:

A series of 3-mercapto-1,2,4-triazole-pyrrole hybrids was designed as antimycobacterial agents by employing 5-(4-(1H-pyrrol-1-yl)phenyl)-4H-1,2,4-triazole-3-thiol as the scaffold onto which several types of moieties were introduced in the triazole ring at N-4 and N-2 and as substituents of the mercapto function. The aforementioned moieties are an allyl or a Ph moiety at N-4; an aminomethyl group at N-2; or Me, substituted benzyl, ethoxycarbonylmethyl, or substituted phenacyl at sulfur. Investigation of the compounds in the resulting library as growth inhibitors of Mycobacterium smegmatis showed that their min. inhibitory concentration was higher than 64 mg/L.

P.; Ribeiro, Adriana S.. The article conveys some information:

Latent fingerprints (LFPs) play an important rule for criminal investigations regarding to the identification and connection of an individual to a crime scene. Herein, we report a non-destructive method for LFPs development based on the electropolymerization of pyrrole derivatives modified with water-soluble groups on stainless steel surfaces containing fingerprint residues. The polymers, namely P1, P2, P3 and P4, and a copolymer of 4 with 3,4-ethylenedioxythiophene P(4-co-EDOT) were electrodeposited by oxidation of the monomers in aqueous LiClO4 by applying potentials (E) of 1.25-1.7 V vs. Ag/AgCl or c.d. (j) of 5.0-10 mA cm-2 for 15-240 s. The quality of the developed fingerprint images was verified by SEM, the Griaule Forensic Fingerprint software and the Bandey classification system. It was possible to observe the enhancement of the visual contrast between the surface and the fingerprint residues, providing high quality images of the developed fingerprints.

Application In Synthesis of 2,5-Dimethoxytetrahydrofuran The article mentions the following:

2D soft nanomaterials are an emerging research field due to their versatile chem. structures, easily tunable properties, and broad application potential. In this study, a benzene-bridged polypyrrole film with a large area, up to a few square centimeters, is synthesized through an interfacial polymerization approach. As-prepared semiconductive films exhibit a bandgap of ≈2 eV and a carrier mobility of ≈1.5 cm2 V-1 s-1, inferred from time-resolved terahertz spectroscopy. The samples are employed to fabricate in-plane micro-supercapacitors (MSCs) by laser scribing and exhibit an ultrahigh areal capacitance of 0.95 mF cm-2, using 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIM][BF4]) as an electrolyte. Importantly, the maximum energy and power densities of the developed MSCs reach values up to 50.7 mWh cm-3 and 9.6 kW cm-3, resp.; the performance surpassing most of the 2D material-based MSCs is reported to date.

The article was written by Guo, Yongkang; Zhang, Lei; Li, Chenglong; Jin, Mengjia; Zhang, Yanli; Ye, Jincheng; Chen, Yu; Wu, Xiaoming; Liu, Xuguang. The article contains the following contents:

We have achieved substitutional doping of ullazine with either two BO units or with one BO unit and one BN unit. The synthesis of these B-doped ullazines is straightforward, using demethylation and borylative cyclization as the key steps. Ullazine cores of both BN/BO-ullazines (2) and bis-BO-ullazines (3) are very close to being planar. Their electronic and photophys. properties were investigated by UV-visible, fluorescence spectroscopy, cyclic voltammetry, and d. functional theory calculations The experimental part of the paper was very detailed, including the reaction process of 2,5-Dimethoxytetrahydrofuran(cas: 696-59-3SDS of cas: 696-59-3)

Related Products of 696-59-3In 2020 ,《Symmetrical and unsymmetrical fluorine-rich ullazines via controlled cycloaromatizations》 was published in Organic Chemistry Frontiers. The article was written by Zhang, Guoxian; Gautam, Prabhat; Chan, Julian M. W.. The article contains the following contents:

Synthesis of a series of fluorine-rich ullazines I and II via well-controlled cycloaromatizations of highly electron-deficient alkynes was reported. Specifically, three sym.-functionalized and three unsym.-functionalized ullazine cores were constructed from 1-(2,6-dialkynylphenyl)-1H-pyrroles via controlled electrophilic cyclizations of highly electron-poor pentafluorosulfanylated (i.e., SF5-containing)phenylethynyl moieties onto the pyrrole. While the diminished reactivity of the electron-poor alkynes was initially problematic, this feature was subsequently found to be pivotal in facilitating thermal control of mono- vs. double 6-endo-trig ring-closure in the key step. Iodinated ullazine products were shown to undergo further facile transformation into more complex unsym. targets. The synthetic strategies reported herein granted access to a host of sym.- and unsym.-decorated fluorine-rich ullazines with potential value as light-harvesting materials (e.g., dye-sensitized solar cells, organic photovoltaics) or as advanced intermediates for further synthetic elaboration.
