On November 1, 2020, Liu, Ya; Zhao, Yunfeng; Cheng, Wei; Zhang, Tao published an article.Product Details of 4569-86-2 The title of the article was Targeted reclaiming cationic dyes from dyeing wastewater with a dithiocarbamate-functionalized material through selective adsorption and efficient desorption. And the article contained the following:

In this work, we applied a novel dithiocarbamate-grafted star-like polymer for efficient reclamation of cationic dyes. This material is highly selective towards cationic dyes and almost completely rejective to anionic dyes. The adsorption kinetics, isotherms, and thermodn. were systematically investigated to analyze the adsorption behavior of cationic dyes onto the material. As compared with other reported adsorbents, this cheap and facilely-prepared material has exceptional adsorption capacities for industrial cationic dyes, e.g., methylene blue (MB, 2624 mg/g), crystal violet (CV, 2553 mg/g), basic fuchsin (BF, 1729 mg/g), and methylene violet 3RAX (MV, 1239 mg/g), being 5-11 times of that reported in literatures. Based on the effects of pH and ionic strength on adsorption, competitive adsorption of the cationic dyes, and FTIR characterization, mechanisms for the adsorption and desorption of cationic dyes were proposed. The adsorbed dyes can be recovered over 95% just by immersing into diluted HCl solution (0.01 M) for 10 min, thus avoiding organic solvent extraction Over 98% of the adsorption capacity was maintained during consecutive reclamation operation. Due to the high selectivity, high adsorption capacity and the ease of efficient regeneration, this material is potentially applicable for targeted reclamation of cationic dyes from dyeing wastewater. The experimental process involved the reaction of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride(cas: 4569-86-2).Product Details of 4569-86-2

And the article contained the following:

A series of (phenyl)(4-methoxynaphthalen-1-yl)methanones I [Ar = Ph, 4-FC6H4, naphthalen-2-yl, etc.] was designed, synthesized via reaction of 1-methoxynaphthalene with aromatic carboxylic acids and evaluated for their antiproliferative activity against human breast cancer cell line (MCF-7). Most of the tested derivatives I showed good to moderate cytotoxicity against MCF-7 cell line, among which compound I [Ar = 3-OH-4-MeOC6H3] (IC50 = 1.47 ± 0.14μM) was found to be the most active compound, which was more active than the standard drug cisplatin (IC50 = 15.24 ± 1.27μM). In vitro tubulin polymerization inhibition assay, EBI competition assay, cell cycle anal. and cell apoptosis assay identified that compound I [Ar = 3-OH-4-MeOC6H3] was a new tubulin polymerization inhibitor by targeting the colchicine binding site. Mol. docking study showed that compound I [Ar = 3-OH-4-MeOC6H3] possessed high binding affinities with the colchicine binding site of tubulin through hydrogen bond, cation-π, and hydrophobic interaction.

Brodrecht, Martin; Herr, Kevin; Bothe, Sarah; de Oliveira, Marcos Jr.; Gutmann, Torsten; Buntkowsky, Gerd published an article in 2019, the title of the article was Efficient building blocks for solid-phase peptide synthesis of spin labeled peptides for electron paramagnetic resonance and dynamic nuclear polarization applications.Formula: C6H10Cl3NO And the article contains the following content:

Specific spin labeling allows the site-selective investigation of biomols. by EPR and DNP enhanced NMR spectroscopy. A novel spin labeling strategy for com. available Fmoc-amino (Fmoc = 9-fluorenylmethoxycarbonyl) acids is developed. In this approach, the PROXYL spin label is covalently attached to the hydroxyl side chain of three amino acids hydroxyproline (Hyp), serine (Ser) and tyrosine (Tyr) by a simple three-step synthesis route. The obtained PROXYL containing building-blocks are N-terminally protected by the Fmoc-protection group, which makes them applicable for the use in solid-phase peptide synthesis (SPPS). This approach allows the insertion of the spin label at any desired position during SPPS, which makes it more versatile than the widely used post synthetic spin labeling strategies. For the final building-blocks, the radical activity is proven by EPR. DNP enhanced solid-state NMR experiments employing these building-blocks in a TCE solution show enhancement factors of up to 26 for 1H and 13C (1H→13C cross-polarization). To proof the viability of the presented building-blocks for insertion of the spin label during SPPS the penta-peptide Acetyl-Gly-Ser(PROXYL)-Gly-Gly-Gly was synthesized employing the spin labeled Ser building-block. This peptide could successfully be isolated and the spin label activity proved by EPR and DNP NMR measurements, showing enhancement factors of 12.1±0.1 for 1H and 13.9±0.5 for 13C (direct polarization). The experimental process involved the reaction of tert-Butyl trichloroacetimidate(cas: 98946-18-0).Formula: C6H10Cl3NO

And the article contained the following:

Isoxazoles are frequently used amide isosteres, as shown in the context of discovery of CRTh2 antagonists from amide I to isoxazole II. However, persistent agonism and poor solubility in isoxazole series presented challenges to its further development. Based on the concept of quality by design (QbD), 5,5-disubstituted isoxazolines III (R1, R2 = alkyl, aryl) were introduced. The chirality at 5 position of isoxazolines controlled the switch between two modes of actions, which led to a novel series of pure antagonists. This non-planar motif also conferred a change of shape of these mols., which avoided flat structures and improved their phys. properties. The experimental process involved the reaction of Methyl 6-chloro-6-oxohexanoate(cas: 35444-44-1).Electric Literature of 35444-44-1

Slonov, Azamat; Musov, Ismel; Zhansitov, Azamat; Rzhevskaya, Elena; Khakulova, Diana; Khashirova, Svetlana published an article in 2020, the title of the article was The effect of modification on the properties of polyetherimide and its carbon-filled composite.Category: chlorides-buliding-blocks And the article contains the following content:

The effect of oligophenylene sulfone (OPSU) and polycarbonate (PC) on the rheol., mech. and thermal properties of polyetherimide (PEI) and a carbon-filled composite based on it was studied. It is shown that the introduction of OPSU and PC leads to a decrease in the melt viscosity of PEI and a carbon-filled composite based on it with the preservation of their mech. properties and heat resistance at a sufficiently high level. It was found that composites with OPSU have higher mech. and thermal properties compared with composites with PC. Samples from modified carbon-filled PEI were printed by the fused deposit modeling (FDM) method. Three-dimensionally printed samples from carbon-filled PEI modified by OPSU showed significantly higher mech. properties than composites with PC.

Chen, Jinying; Sang, Zitai; Jiang, Youjun; Yang, Chao; He, Linhong published an article in 2019, the title of the article was Design, synthesis, and biological evaluation of quinazoline derivatives as dual HDAC1 and HDAC6 inhibitors for the treatment of cancer.Application of 35444-44-1 And the article contains the following content:

Fifty-eight quinazoline-based compounds were designed and synthesized based on the structural optimizations from the lead compound 23bb in an attempt to search for more potent dual HDAC1 and HDAC6 inhibitors. Among them, 32c (HDAC1, IC50 = 31.10 ± 0.37 nM; HDAC6, IC50 = 16.15 ± 0.62 nM) and 32d (HDAC1, IC50 = 37.00 ± 0.24 nM; HDAC6, IC50 = 35.00 ± 0.71 nM) were not only identified as potent dual-acting HDAC1 and HDAC6 inhibitors with over 10-fold selectivity to the other HDACs, but also displayed activities in tubulin acetylation and histone H3 acetylation induction. Importantly, both of them displayed strong antiproliferative activities against various tumor cell lines in vitro with IC50 values <40 nM, especially for hematol. tumors cells (U266 and RPMI8226, IC50 < 1 nM), which were even better than 23bb and SAHA. Furthermore, 32c showed a significant tumor growth inhibition (antitumor rate = 63.98%, p < 0.05) in the resistant MCF-7/ADR xenograft model without any obvious body weight changes and abnormal behaviors. The authors' findings validate that 32c is a potent dual inhibitor of HDAC1/6 that can be an efficacious treatment for breast cancer with Adriamycin resistance. The experimental process involved the reaction of Methyl 6-chloro-6-oxohexanoate(cas: 35444-44-1).Application of 35444-44-1
