Author is Kobayashi, Naotake; Sato, Norihito; Sugita, Katsuji; Takahashi, Kouji; Sugawara, Tamio; Tada, Yukio; Yoshikawa, Takayoshi.

We discovered the orally active TSH-releasing hormone (TRH) mimetic: (4S,5S)-5-methyl-N-{(2S)-1-[(2R)-2-methylpyrrolidin-1-yl]-1-oxo-3-(1,3-thiazol-4-yl)propan-2-yl}-2-oxo-1,3-oxazolidine-4-carboxamide 1 (rovatirelin). The central nervous system (CNS) effect of rovatirelin after i.v. (iv) administration is 100-fold higher than that of TRH. As 1 has four asym. carbons in its mol., there are 16 stereoisomers. We synthesized and evaluated the anti-hypothermic effect of all stereoisomers of 1, which has the (4S),(5S),(2S),(2R) configuration from the N-terminus to the C-terminus, in order to clarify the structure-activity relationship (SAR) of stereoisomers. The (4R),(5R),(2R),(2S)-isomer 16 did not show any anti-hypothermic effect. Only the (4S),(5S),(2S),(2S)-isomer 10, which has the (2S)-2-methylpyrrolidine moiety at the C-terminus showed the anti-hypothermic effect similar to 1. Stereoisomers, which have the (5R) configuration of the oxazolidinone at the N-terminus and the (2R) configuration at the middle-part, showed a much lower anti-hypothermic effect than that of 1. On the other hand, stereoisomers, which have the (4R) configuration of the oxazolidinone at the N-terminus or the (2S) configuration of the C-terminus, have little influence on the anti-hypothermic effect.

Quality Control of 2,5-Diphenyloxazole. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 2,5-Diphenyloxazole, is researched, Molecular C15H11NO, CAS is 92-71-7, about Catalytic C-H/C-F Coupling of Azoles and Acyl Fluorides.

A method for the palladium/copper-catalyzed direct acylation of azoles with acyl fluorides is described. This study reports the first examples of acyl fluorides being used as acylation reagents in transition-metal-catalyzed aromatic C-H bond functionalization reactions. Depending on the reaction temperature, decarbonylative coupling may also occur. Mechanistic studies suggest that the cleavage of the aromatic C-H bond, promoted by a copper-phosphine species, is not the rate-limiting step of this acylation.

Product Details of 92-71-7. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 2,5-Diphenyloxazole, is researched, Molecular C15H11NO, CAS is 92-71-7, about Gated liquid scintillator detector for neutron time of flight measurements in a gas-puff Z-pinch experiment. Author is Ruskov, E.; Glebov, V. Yu.; Darling, T. W.; Wessel, F. J.; Conti, F.; Valenzuela, J. C.; Rahman, H. U.; Beg, F. N..

Detection of secondary D(t, n)4He neutrons produced when thin Ar or Kr gas shells implode on a D gas target is a very challenging task because the secondary neutron yield is a small fraction of the primary neutron yield and because the implosion is often accompanied by an intense hard x-ray burst. The authors built a large volume neutron time of flight (nTOF) detector using liquid scintillator (xylene solvent with small quantities of wavelength shifting PPO + bis-MSB fluors) in an attempt to increase the detection probability for secondary neutrons in staged Z-pinch experiments at the 1 MA Zebra pulsed-power generator. Two fast, gated microchannel plate photomultiplier tubes detect the light created in 21 L of liquid The hard x-rays were successfully suppressed in the recorded nTOF traces, but the authors found no evidence of secondary neutrons. The signal quality from the primary D(d, n)3He neutrons was higher compared to the signal quality from a plastic scintillator nTOF, thus providing a more reliable estimate of the D ion temperature at the pinch stagnation time. Cross-calibration with a Ag activation detector enables standalone neutron yield measurement. (c) 2019 American Institute of Physics.

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.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2,5-Diphenyloxazole(SMILESS: C1(C2=CC=CC=C2)=NC=C(C3=CC=CC=C3)O1,cas:92-71-7) is researched.Computed Properties of C15H11NO. The article 《Thermal neutron sensitive inorganic compound loaded thin-film composite plastic scintillators》 in relation to this compound, is published in Applied Radiation and Isotopes. Let’s take a look at the latest research on this compound (cas:92-71-7).

The paper describes the preparation and characterization methodol. of thermal neutron sensitive inorganic compound loaded polystyrene based thin-film Plastic Scintillators (PS). Inorganic compounds with thermal neutron sensitive elements such as B2O3, LiF, Gd2O2S:Tb, Gd2O3, Gd(BO2)3:Tb is loaded in plastic scintillators, at predetermined weight percentage in a solvent-based fabrication method. The PS base solution is prepared by dissolving required quantities of polystyrene, 2,5-Diphenyloxazole (PPO), 1,4-bis(5-Phenyloxazol-2-yl) Benzene (POPOP) in the p-xylene solvent. The loading material is mixed with the scintillator solution and coated over cellulose acetate-based transparency sheet. Thin sheets of 200 x 150 mm size and 250 ± 50 μm thickness PS are prepared through multiple coating. Photoluminescence (PL), Radioluminescence (RL) and pulse height spectra (PHS) of α, β, γ and neutron sources of the composite scintillators are studied. The selection of loading compounds is decided on their phys. properties such as refractive index, the at. percentage of neutron sensitive elements in the inorganic compound, band gap, and cost and availability of material. Gadolinium based compounds as a thermal neutron absorber showed higher detection capability for low-energy neutrons. Among the gadolinium loaded PS, Gd(BO2)3:Tb (14.3 wt%) composite scintillator showed the highest RL. A comprehensive anal. of PL, RL, PHS of α, pure β and γ sources, un-moderated and moderated Am-Be neutron source is discussed in the paper.

Abstract: This paper presents measurements of the scintillation light yield and time profile for a number of concentrations of water-based liquid scintillator, formulated from linear alkylbenzene (LAB) and 2,5-diphenyloxazole (PPO). We find that the scintillation light yield is linear with the concentration of liquid scintillator in water between 1 and 10% with a slope of 127.9±17.0 ph/MeV/concentration and an intercept value of 108.3±51.0 ph/MeV, the latter being illustrative of non-linearities with concentration at values less than 1%. This is larger than expected from a simple extrapolation of the pure liquid scintillator light yield. The measured time profiles are consistently faster than that of pure liquid scintillator, with rise times less than 250 ps and prompt decay constants in the range of 2.1-2.85 ns. Addnl., the separation between Cherenkov and scintillation light is quantified using cosmic muons in the CHESS experiment for each formulation, demonstrating an improvement in separation at the centimeter scale. Finally, we briefly discuss the prospects for large-scale detectors.

Product Details of 92-71-7. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 2,5-Diphenyloxazole, is researched, Molecular C15H11NO, CAS is 92-71-7, about Plastic scintillators with efficient light output and pulse shape discrimination produced via photoinitiated polymerization. Author is Lim, Allison; Mahl, Adam; Latta, Joseph; Yemam, Henok A.; Greife, Uwe; Sellinger, Alan.

Poly(vinyl toluene) (PVT) overdoped with 2,5-diphenyloxazole and using 1,4-bis(5-phenyloxazol-2-yl)benzene as a fluorescent secondary dopant can be used to detect and differentiate neutron and gamma radiation via scintillation. The low cost of PVT makes these plastic scintillators attractive for both portable and larger sized first line detection of special nuclear materials. Current fabrication methods rely on thermally initiated radical polymerization that generally requires an approx. 5-day heating process in order to produce high quality scintillators. In this work, we report a proof-of-concept photopolymerization process to prepare plastic scintillators up to 20 g in size in 1 day. These plastic scintillators were comparable to standard thermally polymerized samples in terms of their phys. properties and response to various radiation sources. © 2018 Wiley Periodicals, Inc.
