Summary : The study aimed to evaluate the biosynthesis and accumulation of lignans, phenolic acids and also the antioxidant activities in 15 varieties of flax sprouts. The differential contents of lignans (13.30-8987μg g-1) and phenolic acids (72.55-597.1μg g-1) among 15 varieties of flax sprouts were observed The total antioxidant activities ranged from 147.2 to 332.8μmol TE g-1 in the flax sprouts. The expression levels of five genes in the lignin synthetic pathway were analyzed using RT-qPCR, and the results showed dramatical differences among different flax sprouts. Relatively dispersed anal. was showed by principal component anal. (PCA), and 15 flax sprouts were grouped by hierarchical cluster anal. (HCA) based on their phenolic acids, lignan compounds, length, gene expression and antioxidants after germination, primarily in relation to variety specificity.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 92-71-7, is researched, Molecular C15H11NO, about Determination of differentiating markers in coicis semen from multi- sources based on structural similarity classification coupled with UPCC-Xevo G2-XS QTOF, the main research direction is coicis semen oil triglyceride MATLAB QTOF; MATLAB; coicis semen; markers; qualitative and quantitative; triglyceride.Computed Properties of C15H11NO.

Coicis semen, a medicinal food, is derived from the dried and mature seeds of Coix lacryma-jobi L. var. ma-yuen (Rom.Caill.) Stapf, a member of the Gramineae family. Lipids are its main constituents. Previous literature reported that coicis semen contains twenty triglycerides and twelve diglycerides. However, we identified thirty-five triglycerides, sixteen diglycerides, four monoglycerides, and two sterols under the preoptimized conditions of UPCC-Xevo G2-XS QTOF combined with a personalized TCM database. Furthermore, we successfully determined glycerol trioleate content to evaluate quality differences. Finally, we identified the fatty acid compositions of seven out of nine differential markers via Progenesis QI using principal component anal., orthogonal projection to latent structures-discriminant anal., and the LipidMaps database. In addition, we applied a software-based classification, a method that was previously developed by our team, to verify and predict structurally similar compounds Our findings confirmed that UPCC-Xevo G2-XS QTOF combined with software-based group classification could be used as an efficient method for exploring the potential lipid markers of seed medicine.

A series of polystyrene-based scintillators have been prepared by thermal polymerization without any initiators. To investigate the influence of the primary additive and wavelength shifter on the performance of plastic scintillator, two primary additives and four wavelength shifters were added to the scintillators, resp. The results showed that 2,5-diphenyloxazole (PPO) and 5-phenyl-2-[4-(5-phenyl-1,3-oxazol-2-yl)phenyl]-1,3-oxazole (POPOP) were the most adequate fluorescent dyes for initiator-free preparation of the polystyrene-based scintillators. The plastic scintillator containing 1% PPO and 0.02% POPOP possessed the highest fluorescence intensity. Initiator-containing polystyrene-based scintillator with the same concentration of PPO and POPOP (1% PPO, 0.02% POPOP and 0.01% AIBN) was also prepared The light yield of the plastic scintillator without any initiators is 83.49% relative to the value of the standard sample EJ-200, which is higher 8% than that of initiator-containing plastic scintillator. Moreover, compared with the standard sample EJ-200 with a decay time of 2.09 s, the decay time of the initiator-free and initiator-containing plastic scintillator was 1.80s and 1.86 s, resp.

Recommanded Product: 2,5-Diphenyloxazole. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 2,5-Diphenyloxazole, is researched, Molecular C15H11NO, CAS is 92-71-7, about A validated high performance liquid chromatography method for simultaneous determination of PPO and POPOP in plastic scintillators. Author is Ergun, Ece; Kantoglu, Omer; Aydin, Busra.

Plastic scintillators are the solid solutions of active additives to polymer matrixes and widely used in various fields of science and technol. such as high-energy physics, radiation chem., nuclear-power engineering, dosimetry and medical imaging. 2,5-diphenyloxazole (PPO) and 1,4-bis(5-phenyl-2- oxazolyl)benzen (POPOP) are the most widely used fluorescent additives (fluors) which lead to scintillation. Since the composition of the fluors determines the photon yield and optical properties of the scintillators, it is important to determine their concentration in the fabricated material. This paper describes a method, for the first time, for accurate determination of PPO and POPOP in plastic scintillators. A complete validation of the anal. procedure (sample preparation + HPLC method) has been performed using three spiking levels at 0.1, 10 and 100 mg L-1 and real plastic scintillator samples. Based on the results, calibration plots of PPO and POPOP were linear over the 0.01 to 150 mg L-1 concentration ranges. The limit of detection and limit of quantification were 0.92 and 2.80μg L-1 for PPO and 2.11 and 6.39μg L-1 for POPOP, resp. The performance of the anal. procedure was also verified through the determination of fluors in a plastic scintillator fabricated via bulk thermal polymerization As a consequence, the data indicate that the proposed anal. procedure for PPO and POPOP determination in plastic scintillators provides good linearity, sensitivity, accuracy, precision and robustness, which allows a novel, simple, fast, economical, and reliable qual. and quant. anal.

Category: thiazole. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2,5-Diphenyloxazole, is researched, Molecular C15H11NO, CAS is 92-71-7, about Inheritance pattern of okra enation leaf curl disease among cultivated species and its relationship with biochemical parameters. Author is Yadav, Yogendra; Maurya, Praveen Kumar; Bhattacharjee, Tridip; Banerjee, Swadesh; Dutta, Subrata; Mandal, Asit Kumar; Chattopadhyay, Arup; Hazra, Pranab.

Okra production in eastern India at present is severely threatened by whitefly-mediated okra enation leaf curl disease (OELCuD). Identification of resistant genotype and understanding the genetic control and biochem. relationship of OELCuD resistance are prerequisite for developing an effective breeding strategy. This study was conducted employing six populations (P1, P2, F1, F2, BC1 and BC2) of two selected (resistant x susceptible (RxS)) crosses. Associationship between severity of OELCuD and biochem. parameters of parents and hybrids at preflowering and flowering stages was studied. Segregation pattern of the genotypes in F2 generation showing OELCuD reaction of two crosses suggested that two duplicate recessive genes was operative for resistance to OELCuD. Generation mean anal. revealed involvement of both additive and nonadditive effects in the inheritance of disease resistance. Hence, postponement of selection in later generations or intermating among the selected segregates followed by one or two generations of selfing to break the undesirable linkage and allow the accumulation of favorable alleles could be suggested for the development of stable resistant genotype against this disease. Higher peroxidase activity and total phenol content in leaf emerged as reliable biochem. markers for early selection of genotype resistant to OELCuD.

Both inhouse human genetic and literature data have converged on the identification of leukotriene 4 hydrolase (LTA4H) as a key target for the treatment of cardiovascular disease. We combined fragment-based crystallog. screening with an iterative medicinal chem. effort to optimize inhibitors of LTA4H. Ligand efficiency was followed throughout our structure-activity studies. As applied within the context of LTA4H inhibitor design, the chem. team was able to design a potent compound 20 (DG-051, I) (Kd = 26 nM) with high aqueous solubility (>30 mg/mL) and high oral bioavailability (>80% across species) that is currently undergoing clin. evaluation for the treatment of myocardial infarction and stroke. The structural biol.-chem. interaction described in this paper provides a sound alternative to conventional screening techniques. This is the first example of a gene-to-clinic paradigm enabled by a fragment-based drug discovery effort.
