Computed Properties of C7H6Cl2On June 1, 2021, Sui, Yan-Fei; Ansari, Mohammad Fawad; Zhou, Cheng-He published an article in Chemistry – An Asian Journal. The article was 《Pyrimidinetrione-imidazoles as a Unique Structural Type of Potential Agents towards Candida Albicans: Design, Synthesis and Biological Evaluation》. The article mentions the following:

A series of pyrimidinetrione-imidazole conjugates I [R1 = H, Et, 2-chlorobenzl, etc.] as potentially antifungal agents were developed. Bioassays manifested that I [R1 = 4-fluorobenzl] exerted favorable inhibition towards C. albicans (MIC=0.002 mM), being 6.5 folds more active than clin. antifungal drug fluconazole (MIC=0.013 mM). Preliminary mechanism research indicated that compound I [R1 = 4-fluorobenzl] could not only depolarize membrane potential but also permeabilize the membrane of C. albicans. Mol. docking was operated to simulate the interaction mode between mol. I [R1 = 4-fluorobenzl] and CYP51. In addition, hybrid I [R1 = 4-fluorobenzl] might form I [R1 = 4-fluorobenzl]-DNA supramol. complex via intercalating into DNA. The interference of membrane and DNA might contributed to its fungicidal capacity with no obvious tendency to induce the resistance against C. albicans. Conjugate I [R1 = 4-fluorobenzl] endowed good blood compatibility as well as low cytotoxicity towards HeLa and HEK-293T cells. In addition to this study using 3-Chlorobenzylchloride, there are many other studies that have used 3-Chlorobenzylchloride(cas: 620-20-2Computed Properties of C7H6Cl2) was used in this study.

《Discovery of a Novel Dual-Target Inhibitor of ERK1 and ERK5 That Induces Regulated Cell Death to Overcome Compensatory Mechanism in Specific Tumor Types》 was written by Wang, Guan; Zhao, Yuqian; Liu, Yao; Sun, Dejuan; Zhen, Yongqi; Liu, Jie; Fu, Leilei; Zhang, Lan; Ouyang, Liang. Related Products of 620-20-2 And the article was included in Journal of Medicinal Chemistry on April 23 ,2020. The article conveys some information:

ERK1 and ERK5 are proposed to have pivotal roles in several types of cancer. Under some circumstance, ERK5 may provide a common bypass route, which rescues proliferation upon abrogation of ERK1 signaling. Thus, we accurately classified the tumor types from The Cancer Genome Atlas (TCGA) based on the expression levels of ERK1 and ERK5. We proposed a novel therapeutic strategy to overcome the above-mentioned compensatory mechanism in specific tumor types by co-targeting both ERK1 and ERK5. On the basis of the idea of overcoming ERK5 compensation mechanism, 22ac (ADTL-EI1712) as the first selective dual-target inhibitor of ERK1 and ERK5 was discovered to have potent antitumor effects in vitro and in vivo. Interestingly, this compound was found to induce regulated cell death accompanied by autophagy in MKN-74 cells. Taken together, our results warrant the potential of this dual-target inhibitor as a new candidate drug that conquers compensatory mechanism in certain tumor types.

The article was written by Xu, Zhian; Xu, Jinxi; Li, Yiqun. The article contains the following contents:

A novel and efficient heterogeneous CuSO4 nanoparticles (CuSO4 NPs) immobilized on CM-cellulose/polyaniline (CuSO4NPs@CMC/PANI) composites were prepared via one-pot and one-step interfacial oxidative polymerization of aniline with sodium CM-cellulose (CMC) as soft template and CuSO4 as catalyst. The in situ formed CuSO4 NPs were dispersed uniformly and firmly on the resultant composites and stabilized by complexation with hydroxyl groups (OH), carboxylate groups (COO-), nitrogen atoms, and delocalized π-π conjugate benzenoid and quinoid moieties of CMC/PANI composites. The morphol., composition, and structure of the as-fabricated composites were systematically characterized by XPS, transmission electron microscopy (TEM), SEM (SEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform IR spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric anal. (TGA), and derivative thermogravimetry (DTG) techniques. The CuSO4NPs@CMC/PANI composites were successfully applied as catalysts in aldehyde-alkyne-amine (A3) coupling reactions, A3-cycloisomerization tandem reactions, and Cu-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. All reactions proceeded smoothly and afforded the desired products in excellent yields. Moreover, no significant decrease in catalytic ability was observed in A3 model reaction after 15 recycles, indicating CuSO4NPs@CMC/PANI composites exhibited easy separability and high reusability. Tolerance of wide scope of substrate, excellent catalytic activity, easy operation, recycling of catalyst, and environmental benign are the salient features of these catalytic process.

《N-Hydroxyphthalimide/benzoquinone-catalyzed chlorination of hydrocarbon C-H bond using N-chlorosuccinimide》 was published in Organic & Biomolecular Chemistry in 2019. These research results belong to Li, Zi-Hao; Fiser, Bela; Jiang, Biao-Lin; Li, Jian-Wei; Xu, Bao-Hua; Zhang, Suo-Jiang. Recommanded Product: 620-20-2 The article mentions the following:

The direct chlorination of C-H bonds has received considerable attention in recent years. In this work, a metal-free protocol for hydrocarbon C-H bond chlorination with com. available N-chlorosuccinimide (NCS) catalyzed by N-hydroxyphthalimide (NHPI) with 2,3-dicyano-5,6-dichlorobenzoquinone (DDQ) functioning as an external radical initiator is presented. Aliphatic and benzylic substituents and also heteroaromatic ones were found to be well tolerated. Both the experiments and theor. anal. indicate that the reaction goes through a process wherein NHPI functions as a catalyst rather than as an initiator. On the other hand, the hydrogen abstraction of the C-H bond conducted by a PINO species rather than the highly reactive N-centered radicals rationalizes the high chemoselectivity of the monochlorination obtained by this protocol as the latter is reactive towards the C(sp3)-H bonds of the monochlorides. The present results could hold promise for further development of a nitroxy-radical system for the highly selective functionalization of the aliphatic and benzylic hydrocarbon C-H.

And the article was published in New Journal of Chemistry in 2020. Quality Control of 3-Chlorobenzylchloride The author mentioned the following in the article:

The optical signals of serum albumin (SA) provide precious information for realizing its native functions, in addition to developing related biomedical applications. Herein, we report a new class of easy synthesizable and water-soluble compounds (BZ1-BZ5) based on different chlorine positions on 9-O-benzyl-substituted berberine scaffolds for the selective detection of bovine serum albumin (BSA) in CP buffer solution (10 mM, pH 7.2) based on two competing factors: hydrophobic interactions and steric repulsion. The frail emission intensities of these probes were enhanced upon the addition of BSA; exceptionally, a remarkable increase in emission intensity (140-fold) and remarkable lifetime and quantum yield increases make BZ4 an excellent fluorescence turn-on hydrophobic BSA sensor. Selectivity and co-existence studies involving other proteins, free tryptophan, etc. revealed that the microenvironment around the tryptophan moiety in BSA incites drastic spectral changes upon the introduction of BSA. Moreover, the most efficient lumino-probe, BZ4, can detect bovine serum albumin at a nanomolar level (LOD = 3.3 nM) with a broadened range of linearity and slight altering of the secondary structure of the protein. Our exptl. results and docking simulation studies show that the probe BZ4 binds preferentially at “”binding site II”” of BSA. In addition, the binding and conformational alterations of BSA provoked by these analogs have been intensely investigated, and we fruitfully relate the binding results to the sensing outcome. The obtained results reveal how the different positioning of chlorine in benzyl-substituted berberine affects the hydrophobic sensing of BSA, making these probes a new category of BSA selective material with potential applications in proteome research.

HPLC of Formula: 620-20-2On September 30, 2021 ,《Cu2+ ion crosslinked carboxymethylcellulose/diatomite composite beads as an efficient catalyst for CuAAC reactions》 was published in Polymers for Advanced Technologies. The article was written by Zeng, Fang; Zhang, Mingjuan; Li, Yiqun. The article contains the following contents:

Cu2+-crosslinked CM-cellulose/diatomite composite beads (CuII@CMC/DE) were prepared in simple and efficient way using ionic crosslinking techniques. In CuII@CMC/DE beads, diatomite serves as a reinforcing filler, and divalent copper cation acts as crosslinking agent. The chem. structure and morphol. of as-fabricated CuII@CMC/DE beads were well characterized using various techniques such as ICP, FT-IR, XRD, SEM, EDS, elemental mapping, TEM, XPS, and TGA. The CuII@CMC/DE beads exerted superior catalytic performance in CuAAC reactions of benzyl halides, sodium azide, and alkynes to yield regioselective 1,4-disubstituted-1,2,3-triazoles in excellent yields under green conditions. In these resultant catalytic composite beads, Cu2+ was used not only as a crosslinking agent but also as a metal catalyst for CuAAC reaction. The composite beads can be easily separated by filter and reused at least four times without any significant decrease on its activity and selectivity.
