On March 15, 2019, Miyake, Yuka; Itoh, Yukihiro; Hatanaka, Atsushi; Suzuma, Yoshinori; Suzuki, Miki; Kodama, Hidehiko; Arai, Yoshinobu; Suzuki, Takayoshi published an article.Formula: C10H8BrNO2 The title of the article was Identification of novel lysine demethylase 5-selective inhibitors by inhibitor-based fragment merging strategy. And the article contained the following:

Histone lysine demethylases (KDMs) have drawn much attention as targets of therapeutic agents. KDM5 proteins, which are Fe(II)/α-ketoglutarate-dependent demethylases, are associated with oncogenesis and drug resistance in cancer cells, and KDM5-selective inhibitors are expected to be anticancer drugs. However, few cell-active KDM5 inhibitors have been reported and there is an obvious need to discover more. In this study, we pursued the identification of highly potent and cell-active KDM5-selective inhibitors. Based on the reported KDM5 inhibitors, we designed several compounds by strategically merging two fragments for competitive inhibition with α-ketoglutarate and for KDM5-selective inhibition. Among them, compounds 10 and 13, which have a 3-cyano pyrazolo[1,5-a]pyrimidin-7-one scaffold, exhibited strong KDM5-inhibitory activity and significant KDM5 selectivity. In cellular assays using human lung cancer cell line A549, 10 and 13 increased the levels of trimethylated lysine 4 on histone H3, which is a specific substrate of KDM5s, and induced growth inhibition of A549 cells. These results should provide a basis for the development of cell-active KDM5 inhibitors to highlight the validity of our inhibitor-based fragment merging strategy. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).Formula: C10H8BrNO2

Yu, Xi-Hui; Cai, Xiong-Jie; Hong, Xiao-Qiao; Tam, Kin Yip; Zhang, Kun; Chen, Wen-Hua published an article in 2019, the title of the article was Synthesis and biological evaluation of aza-crown ether-squaramide conjugates as anion/cation symporters.Electric Literature of 574-98-1 And the article contains the following content:

Anion/cation symport across cellular membranes may lead to cell apoptosis and be developed as a strategy for new anticancer drug discovery. Four aza-crown ether-squaramide conjugates were synthesized and characterized. Their anion recognition, anion/cation symport, cytotoxicity and probable mechanism of action were investigated in details. These conjugates are able to form ion-pairing complexes with chloride anions and facilitate the transmembrane transport of anions via an anion/cation symport process. They can disrupt the cellular homeostasis of chloride anions and sodium cations and induce the basification of acidic organelles in live cells. These conjugates exhibit moderate cytotoxicity toward the tested cancer cells and trigger cell apoptosis by mediating the influx of chloride anions and sodium cations into live cells. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).Electric Literature of 574-98-1

On January 31, 2020, Dato, Florian M.; Neudoerfl, Joerg-Martin; Guetschow, Michael; Goldfuss, Bernd; Pietsch, Markus published an article.Reference of 2-(2-Bromoethyl)isoindoline-1,3-dione The title of the article was ω-Quinazolinonylalkyl aryl ureas as reversible inhibitors of monoacylglycerol lipase. And the article contained the following:

The serine hydrolase monoacylglycerol lipase (MAGL) is involved in a plethora of pathol. conditions, in particular pain and inflammation, various types of cancer, metabolic, neurol. and cardiovascular disorders, and is therefore a promising target for drug development. Although a large number of irreversible-acting MAGL inhibitors have been discovered over the past years, there are only few compounds known so far which inhibit the enzyme in a reversible manner. Therefore, much effort is put into the development of novel chem. entities showing reversible inhibitory behavior, which is thought to cause less undesired side effects. To explore a wide range of chem. structures as MAGL binders, we have applied a virtual screening approach by docking small mols. into the crystal structure of human MAGL (hMAGL) and envisaged a library of 45 selected compounds which were then synthesized. Biochem. investigations included the determination of the inhibitory potency on hMAGL and two related hydrolases, i.e. human fatty acid amide hydrolase (hFAAH) and murine cholesterol esterase (mCEase). The most promising candidates from theses analyses, i.e. three ω-quinazolinonylalkyl aryl ureas bearing alkyl spacers of three to five methylene groups, exhibited IC50 values of 20-41μM and reversible, detergent-insensitive behavior towards hMAGL. Among these compounds, the inhibitor 1-(3,5-bis(trifluoromethyl)phenyl)-3-(4-(4-oxo-3,4-dihydroquinazolin-2-yl)butyl)urea (96) was selected for further kinetic characterization, yielding a dissociation constant Ki = 15.4μM and a mixed-type inhibition with a pronounced competitive component (α = 8.94). This mode of inhibition was further supported by a docking experiment, which suggested that the inhibitor occupies the substrate binding pocket of hMAGL. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).Reference of 2-(2-Bromoethyl)isoindoline-1,3-dione

And the article contained the following:

A new series of 1,2,4-triazolin-3-one and phthalimide heterodimers I [X = (CH2)n; n = 1, 2, 9, etc.] was synthesized and evaluated for their insecticidal and acetylcholinesterase inhibitory activities. Most of the synthesized compounds I showed good in vitro inhibitory activities against both Drosophila melanogaster acetylcholinesterase (DmAChE) and Musca domestica acetylcholinesterase (MdAChE). Among them, compound I (n = 7) was found to be most potent AChE inhibitor (IC50 = 8.07 μM to DmAChE, IC50 = 32.24 μM to MdAChE), whose activities were 2.31- and 1.35-fold more active than the pos. control ethion (CP, IC50 = 18.62 μM to DmAChE, IC50 = 43.56 μM to MdAChE). The docking model study revealed that compound I (n = 7) possessed fitted spatial structure and bound to central pocket and peripheral site of DmAChE. Moreover, most of the compounds I demonstrated high insecticidal activity to Lipaphis erysimi and Tetranychus cinnabarinus at concentration of 300 mg/L.
