Dysprosium β-diketonate compounds have recently gained a lot of attention due to their intriguing multifunctional properties. In this paper, a series of “”Dy(hfa)3•glyme”” adducts have been prepared through a one-pot reaction, in dichloromethane, from dysprosium(III) acetate monohydrate, hexafluoroacetylacetone and glyme [Hhfa = 1,1,1,5,5,5-hexafluoroacetylacetone, glyme = bis-(2-methoxyethyl)ether, 2,5,8,11-tetraoxadodecane, 2,5,8,11,14-pentaoxapentadecane]. Based on the length of the polyether, various coordination frameworks have been obtained going from a mononuclear [Dy(hfa)3•diglyme] adduct, to a polymeric chain system for the [Dy(hfa)3•2H2O•triglyme], and an ionic structure for the [Dy(hfa)2•tetraglyme]+[Dy(hfa)4]-. The relationship between the coordination framework in the “”Dy(hfa)3•glyme”” series and the magnetic and luminescent properties has been deeply investigated.

Huang, Muhua; Wu, Jinfeng; Dong, Jingcheng published the artcile< Modified BuShenYiQi formula alleviates experimental allergic asthma in mice by negative regulation of type 2 innate lymphoid cells and CD4+ type 9 helper T cells and the VIP-VPAC2 signalling pathway>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is BuShenYiQi formula ILC2 Th9 VIP VPAC2 signalling allergic asthma; Chinese medicine; airway inflammation; neuro-immune communication; type 2 immune response.

Modified BuShenYiQi formula (M-BYF) is derived from BuShenYiQi formula, used for the treatment of allergic asthma. The exact effect and mechanism of M-BYF on the improvement of asthma remain unclear. We investigated the mechanism underlying the therapeutic effect of M-BYF on allergic asthma. The asthma model was established in female BALB/c mice that were sensitized and challenged with ovalbumin (OVA). Mice in the treated groups were orally treated once a day with M-BYF (7, 14 and 28 g/kg/d) or dexamethasone before OVA challenge. Control and Model group received saline. Pathophysiol. abnormalities and percentages of lung type 2 innate lymphoid cells (ILC2s) and Th9 cells were measured. Expression levels of type 2 cytokines and transcription factors required for these cells function and differentiation were analyzed. Expression of vasoactive intestinal polypeptide (VIP)-VPAC2 signalling pathway-related proteins, and percentages of VIP expressing (VIP+) cells and VPAC2, CD90 co-expressing (VPAC2+CD90+) cells were detected. M-BYF alleviated airway hyperresponsiveness, inflammation, mucus hypersecretion and collagen deposition in asthmatic mice. M-BYF down-regulated percentages of ILC2s and Th9 cells with lower expression of GATA3, PU.1 and IRF4, reduced IL-5, IL-13, IL-9 and VIP production The decrease in the expression of VIP-VPAC2 signalling pathway and percentages of VIP+ cells, VPAC2+CD90+ cells were observed after M-BYF treatment. The LD50 value of M-BYF was higher than 90 g/kg. M-BYF alleviated exptl. asthma by neg. regulating ILC2s and Th9 cells and the VIP-VPAC2 signalling pathway. These findings provide the theor. basis for future research of M-BYF in asthma patient population.

Frkic, Rebecca L.; He, Yuanjun; Rodriguez, Beatriz B.; Chang, Mi Ra; Kuruvilla, Dana; Ciesla, Anthony; Abell, Andrew D.; Kamenecka, Theodore M.; Griffin, Patrick R.; Bruning, John B. published the artcile< Structure-Activity Relationship of 2,4-Dichloro-N-(3,5-dichloro-4-(quinolin-3-yloxy)phenyl)benzenesulfonamide (INT131) Analogs for PPARγ-Targeted Antidiabetics>, Product Details of C19H34O2, the main research area is dichlorodichloroquinolinyloxyphenylbenzenesulfonamide INT131 analog preparation PPARgamma agonist antidiabetic target.

Peroxisome Proliferator-Activated Receptor γ (PPARγ) is a nuclear receptor central to fatty acid and glucose homeostasis. PPARγ is the mol. target for type 2 diabetes mellitus (T2DM) therapeutics TZDs (thiazolidinediones), full agonists of PPARγ with robust antidiabetic properties, which are confounded with significant side effects. Partial agonists of PPARγ such as INT131 (1), have displayed similar insulin-sensitizing efficacy as TZDs, but lack many side-effects. To probe the structure-activity relationship (SAR) of the scaffold (1), the authors synthesized 14 analogs of compound (1) which revealed compounds with higher transcriptional potency for PPARγ and identification of moieties of the scaffold (1) key to high transcriptional potency. The sulfonamide linker is critical to activity, substitutions at position 4 of the benzene ring A were associated with higher transcriptional activity, substitutions at position 2 aided in tighter packing and activity, and the ring type and size of ring A affected the degree of activity.

Yang, Shicong; Liu, Xiaoyan; He, Jingyu; Liu, Menghua published the artcile< Insight into Seasonal Change of Phytochemicals, Antioxidant, and Anti-Aging Activities of Root Bark of Paeonia suffruticosa (Cortex Moutan) Combined with Multivariate Statistical Analysis>, Reference of 112-63-0, the main research area is Paeonia suffruticosa root bark phytochem antioxidant antiaging activity; root bark phytochem seasonal change multivariate statistical analysis; Cortex Moutan; anti-aging; antioxidant; collection period; composition; multivariate statistical analysis.

Chem. compositions, antioxidants, and anti-aging activities of Cortex Moutan (CM), from different collection periods and different producing areas, were measured and compared in order to obtain excellent CM extracts The bioactivities of CM extracts were examined by an in vitro antioxidant method and a UVB irradiated human dermal fibroblast (HDF) model. Phytochem. properties were obtained from ultra-fast liquid chromatog. quadrupole time-of-flight mass spectrometry (UFLC-Q-TOF-MS) prior to the multivariate statistical anal. As for the results, the extracts of Heze CM (HZCM) and Luoyang CM (LYCM) collected in June had better in vitro antioxidant activities, significantly increased the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), and reduced the content of malondialdehyde (MDA), compared to other CM extracts HZCM and LYCM extracts could upregulate the relative expression of SOD and GSH-Px mRNA. The extract of HZCM collected in June could significantly repress the production of matrix metalloproteinase 1 (MMP-1) and improve the production of procollagen type I (PCOL)-I in UVB irradiated HDF. In total, 50 compounds, including 17 monoterpenoids, 19 flavonoids, 13 phenols, and 1 amino acid were identified or tentatively identified in the CM extracts Gallic acid, p-hydroxybenzoic acid, oxypaeoniflorin, paeoniflorin, 1,2,3,4,6-O-pentagalloyl glucose, and paeonol were predominant compounds in the CM extracts Taken together, CM collected from Apr. to Sept. had better antioxidant and anti-aging effects for external usage.

Xu, Jing; Su, Guannan; Huang, Xinyue; Chang, Rui; Chen, Zhijun; Ye, Zi; Cao, Qingfeng; Kijlstra, Aize; Yang, Peizeng published the artcile< Metabolomic analysis of aqueous humor identifies aberrant amino acid and fatty acid metabolism in Vogt-Koyanagi-Harada and Behcet′s disease>, Category: esters-buliding-blocks, the main research area is Behcet disease metabolomic analysis fatty acid metabolism; Behcet’s disease; Vogt-Koyanagi-Harada disease; amino acids; fatty acids; metabolomics; pathway.

To investigate aqueous metabolic profiles in Vogt-Koyanagi-Harada (VKH) and Behcet′s disease (BD), we applied ultra-high-performance liquid chromatog. equipped with quadrupole time-of flight mass spectrometry in aqueous humor samples collected from these patients and controls. Metabolite levels in these three groups were analyzed by univariate logistic regression. The differential metabolites were subjected to subsequent pathway anal. by MetaboAnalyst. The results showed that both partial-least squares discrimination anal. and hierarchical clustering anal. showed specific aqueous metabolite profiles when comparing VKH, BD, and controls. There were 28 differential metabolites in VKH compared to controls and 29 differential metabolites in BD compared to controls. Amino acids and fatty acids were the two most abundant categories of differential metabolites. Furthermore, pathway enrichment anal. identified several perturbed pathways, including pantothenate and CoA biosynthesis when comparing VKH with the control group, and D-arginine and D-ornithine metabolism and phenylalanine metabolism when comparing BD with the control group. Aminoacyl-tRNA biosynthesis was altered in both VKH and BD when compared to controls. Our findings suggest that amino acids metabolism as well as two fatty acids, palmitic acid and oleic acid, may be involved in the pathogenesis of BD and VKH.

Shivalingam, Arun; Taemaitree, Lapatrada; El-Sagheer, Afaf H.; Brown, Tom published the artcile< Squaramides and Ureas: A Flexible Approach to Polymerase-Compatible Nucleic Acid Assembly>, Computed Properties of 112-63-0, the main research area is squaramide ureas flexible nucleic acid assembly; RNA detection; ligation; nucleic acids; polymerase chain reaction; squaramide.

Joining oligonucleotides together (ligation) is a powerful means of retrieving information from the nanoscale. To recover this information, the linkages created must be compatible with polymerases. However, enzymic ligation is restrictive and current chem. ligation methods lack flexibility. Herein, a versatile ligation platform based on the formation of urea and squaramide artificial backbones from minimally modified 3′- and 5′-amino oligonucleotides is described. One-pot ligation gives a urea linkage with excellent read-through speed, or a squaramide linkage that is read-through under selective conditions. The squaramide linkage can be broken and reformed on demand, while stable pre-activated precursor oligonucleotides expand the scope of the ligation reaction to reagent-free, mild conditions. The utility of the authors’ system is demonstrated by replacing the enzymically biased RNA-to-DNA reverse transcription step of RT-qPCR with a rapid nucleic-acid-template-dependent DNA chem. ligation system, that allows direct RNA detection.
