Wang, Dan; Zhao, Li; Hao, Zhiyan; Huang, Ying; Liao, Yang; Wang, Lingli; Zhang, Jinfeng; Cao, Shan; Liu, Lixiao published the artcile< High-throughput and untargeted metabolic profiling revealed the potential effect and mechanisms of paeoniflorin in young asthmatic rats>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is asthma metabolic profiling paeoniflorin; action mechanism 3; biomarker; metabolites; metabolomics; pathways.

Paeoniflorin (PF) is a multi-target monoterpenoid glycoside and possesses broad pharmacol. functions, e.g., anti-inflammation, anti-depression, antitumor, abirritation, neuroprotection, antioxidant, and enhancing cognitive and learning ability. PF has gained a large amount of attention for its effect on asthma disease as the growth rate of asthma has increased in recent years. However, its mechanism of action on asthma is still unclear. In this study, we have explored the action mechanism of PF on asthma disease. Furthermore, high-throughput untargeted metabolic profiling was performed through ultraperformance liquid chromatog./electrospray ionization quadruple time-of-flight high-definition mass spectrometry (QA) UPLC-Q/TOF-MS combined with pattern recognition approaches and pathway anal. A total of 20 potential biomarkers were discovered by UPLC/MS and urine metabolic profiling. The key pathways including the citrate cycle (the TCA cycle), pyrimidine metabolism, pentose phosphate pathway, tyrosine metabolism, and tryptophan metabolism were affected by PF. In conclusion, we have discovered metabolite biomarkers and revealed the therapeutic mechanism of PF based on liquid chromatog. coupled with mass spectrometry untargeted metabolomics. The untargeted metabolomics combined with UPLC-MS is a useful tool for exploring the therapeutic mechanism and targets of PF in the treatment of asthma. Metabolomics combined with UPLC-MS is an integrated method to explore the metabolic mechanism of PF in the treatment of asthma rats and to reveal the potential targets, providing theor. support for the study of the treatment of PF.

Johannesson, Jenny; Hansson, Paula; Bergstroem, Christel A. S.; Paulsson, Mattias published the artcile< Manipulations and age-appropriateness of oral medications in pediatric oncology patients in Sweden: Need for personalized dosage forms>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is pediatric oncol oral medications age Sweden; Age-appropriate; Drug manipulation; Oncology; Oral medication; Pediatric; Personalized dosage form.

Due to the lack of age-appropriate formulations for children, healthcare professionals and caregivers frequently manipulate dosage forms to facilitate oral administration and obtain the required dose. In this study, we investigated drug manipulation and age-appropriateness of oral medications for pediatric oncol. patients with the aim of identifying the therapeutic needs for personalized dosage forms. An observational study at a pediatric oncol. ward, combined with anal. of the age-appropriateness of the oral medications, was performed. Nurses frequently manipulated solid dosage forms to administer them via enteral feeding tubes. Of the active pharmaceutical ingredients (APIs) assessed for age-appropriateness, 74% (29 of 39) were identified to need personalization, either because of lack of child-friendly dosage form, suitable dosage strength, or both. Most APIs, due to limited solubility, were sensitive to formulation changes, such as drug manipulation. This study demonstrates problems and therapeutic needs regarding oral dosage forms in treatment of children with cancer. Expertise in formulation design, new manufacturing technologies, and patient-centered information are needed to address age-appropriate formulations for children.

Gunawan, Steven; Nichol, Gary; Hulme, Christopher published the artcile< Concise route to a series of novel 3-(tetrazol-5-yl)quinoxalin-2(1H)-ones>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is multicomponent reaction Ugi Azide quinoxalinone tetrazole preparation; benzodiazepine tetrazole preparation Ugi azide multicomponent reaction.

This Letter presents a novel three step solution phase protocol to synthesize 3-(tetrazol-5-yl)quinoxalin-2(1H)-ones. The strategy utilizes Et glyoxalate and mono-N-Boc-protected-o-phenylenediamine derivatives in the Ugi-Azide multi-component reaction (MCR) to generate a unique 1,5-disubstituted tetrazole. Subsequent acid treatment stimulates a simultaneous Boc deprotection and intramol. cyclization leading to bis-3,4-dihydroquinoxalinone tetrazoles. Direct oxidation using a stable solid-phase radical catalyst (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) with ceric ammonium nitrate (CAN) in catalytic fashion, initiating aerobic oxidation, completes the entire procedure to generate a series of original unique quinoxalinone tetrazoles, e.g., I. The method was also expanded to produce a benzodiazepine tetrazole, II.

Akiyama, Ryo; Matsuki, Norio; Nomura, Hiroshi; Yoshida, Hisao; Yoshida, Tomoko; Kobayashi, Shu published the artcile< Nontoxic, nonvolatile, and highly efficient osmium catalysts for asymmetric dihydroxylation of alkenes and application to one mol-scale synthesis of an anticancer drug, camptothecin intermediate>, Electric Literature of 112-63-0, the main research area is Sharpless dihydroxylation osmium polymer catalyst prepare.

Novel polymer-incarcerated osmium (PI Os) catalysts have been developed. The osmium (Os) catalysts were shown to be nontoxic and nonvolatile, and stable for several months in air. Asym. dihydroxylation of alkenes using these Os catalysts proceeded smoothly to afford the corresponding diols in high yields with high enantioselectivities. The catalysts could be recovered and reused. A one mol-scale preparation of a key intermediate for camptothecin (anticancer drug, antitumor agent, quinoline alkaloid topoisomerase inhibitor) was successfully demonstrated by using the catalysts. The synthesis of the target compound was achieved using 4-ethyl-8-methoxy-1H-pyrano[3,4-c]pyridine (I) as a starting material and (DHQD)2PYR [(9S,9”S)-9,9”-[(2,5-diphenyl-4,6-pyrimidinediyl)bis(oxy)]bis[(0,11-dihydro-6′-methoxy)cinchonan]] as a ligand. The target compounds thus formed [i.e., (3R,4S)-4-ethyl-3,4-dihydro-8-methoxy-1H-pyrano[3,4-c]pyridine-3,4-diol (II)] was transformed into a camptothecin precursor, (4S)-4-ethyl-1,4-dihydro-4-hydroxy-8-methoxy-3H-pyrano[3,4-c]pyridin-3-one.

Xu, Zhongzheng; Li, Lin; Liu, Jiawei; Dai, Caili; Sun, Wen; Chen, Jia; Zhu, Zhixuan; Zhao, Mingwei; Zeng, Hongbo published the artcile< Mussel-inspired superhydrophilic membrane constructed on a hydrophilic polymer network for highly efficient oil/water separation>, COA of Formula: C9H3F5O2, the main research area is polydopamine superhydrophilic membrane oil water separation; Mussel-inspired materials; Oil/water separation; Polymer network; Superhydrophilic surface.

Superhydrophilic/underwater superoleophobic membrane constructed by hydrophilic polymers possesses great advantage in the separation of oily waste water, due to its intrinsic oil-repellent property. The formation of hydration layer to repel and block oil is considered as the mechanism of underwater superoleophobicity and subsequent oil/water separation Constructing a stable hydrophilic polymer network on the substrate surface would significantly improve the robustness of hydration layer. In this work, a feasible and universal mussel-inspired dip-coating method was developed for constructing stable hydrophilic polymer network onto target substrate surface, via successively immersing substrate membranes into aqueous solutions of polydopamine (PDA) and catechol-functionalized hydrophilic polymer (CFHP). After pre-wetting with water, the polymer network would swell with water to form a thin and stable water film layer, serving as a barrier against oil penetration. The as-prepared CFHP/PDA modified membranes exhibit outstanding performance in separating various oil/water mixtures and oil-in-water emulsions stabilized by surfactants, with separation flux up to 5641.1 L璺痬-2璺痟-1 and separation efficiency achieving 99.98%. The surface modification method developed in this work can be easily extended to various materials and membrane systems, for achieving a variety of practical applications such as industrial wastewater treatment.

Liu, Xinhua; Wang, Youyou; Wang, Xuechuan; Han, Tengfei; Wang, Wanni; Jiang, Huie published the artcile< A salt-free pickling and chrome-free tanning technology: a sustainable approach for cleaner leather manufacturing>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is salt chrome free pickling tanning clean leather manufacture.

Tannery effluents contain harmful pollutants, such as chromium, total dissolved solids, and neutral salts (chlorides), and hence researchers have focused on eco-benign pickling and tanning processes. Here, a sustainable approach employs a salt-free pickling and chrome-free tanning process for cleaner leather manufacturing Pretreatment with 8% epoxy-terminated hyperbranched poly(amine-ester) (abbreviated as EHBP) before pickling controlled the swelling of the skin in the pickling process, in the absence of conventional neutral salts. Subsequent tanning preferably with a 6% aluminum tanning agent (abbreviated as AL) improved the hydrothermal stability of the resultant crust. It also promoted the subsequent dyeing or fatliquoring in a wet finishing process, as well as ameliorated the yellowing resistance and chem. stability of the tanned leather. This study showed that without compromising on the quality of finished leather, EHBP could ensure a salt-free pickling and chrome-free tanning process and prevent the pollution of tannery effluents (Cl- and Cr3+) with a promising development for large-scale green production

Lee, Hesol; Lee, Sullim; Baek, Ji Yun; Seo, Chang-Seob; Yun, Hwayoung; Kim, Su-Nam; Kang, Ki Sung; Choi, You-Kyung published the artcile< Estrogenic activity of ethyl gallate and its potential use in hormone replacement therapy>, Product Details of C19H34O2, the main research area is ethyl gallate estrogen receptor component hormone replacement therapy; Estrogen receptor; Ethyl gallate; Hormone replacement therapy.

We aimed to compare the estrogenic activities of compounds isolated from Moutan Cortex Radicis (MRC, Paeonia suffruticosa Andrews) and identify their potential use in hormone replacement therapy. We quantified seven marker components (gallic acid, oxypaeoniflorin, paeoniflorin, Et gallate, benzoic acid, benzoylpaeoniflorin, and paeonol) in MRC using a high-performance liquid chromatog. simultaneous anal. assay. To investigate the estrogenic activity of MRC and the seven marker components, an E-screen assay was conducted using the estrogen receptor (ER)-pos. MCF-7 human breast cancer cell line. Among them, Et gallate caused cell proliferation in a concentration-dependent manner at concentrations above 25娓璏 and was clearly suppressed by combination treatment with the ER antagonist ICI 182,780. Therefore, Et gallate may be a compound of MRC that can increase the estrogenic effect in ER-pos. MCF-7 cells.
