Alterations in the lipid profile of blood plasma on various fat diets were assessed and were less significant with high-fat diets (58% of total cal.), for free and total cholesterol, free fatty acids, and phosphatides than for triglycerides (I) in 2 healthy male volunteers. The I content was lowest when the fat intake was high, and vice versa. The high I content on a fat-poor diet (5% of total cal.) resulted from transport lipemia from tissues to liver, which was unnecessary on a high-fat diet, since the liver received supplies of fatty acids from the intestine.

Application of 129-18-0. 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: Sodium 4-butyl-3,5-dioxo-1,2-diphenylpyrazolidin-4-ide, is researched, Molecular C19H19N2NaO2, CAS is 129-18-0, about Physiological and drug-induced changes in the glycogen content of mouse brain. Author is Hutchins, D. A.; Rogers, Keith James.

The effect of the method of killing on the concentration of glycogen in mouse brain was determined The cerebral glycogen content of mice killed by immersion in liquid N did not differ significantly from that of animals decapitated and the heads immediately frozen. A delay before freezing led to the rapid loss of brain glycogen, with a 17% fall at 10 sec and an 82% loss after 5 min. Hyperglycemia, induced by the administration of D-glucose, resulted in an 8.3% loss of brain glycogen after 120 min. Insulin hypoglycemia produced a 10.7% fall in glycogen at 60 min followed by an 11.2% increase at 120 min. Exposure to either high (32°) or low (10°) ambient temperatures, caused a depletion of brain glycogen. A circadian rhythm of brain glycogen concentration was found, with a nadir which was coincident with the peak of locomotor activity and body temperature Drugs from several pharmacol. classes were studied for their in vivo effect on the concentration of glycogen in mouse brain. Brain glycogen was increased by all the depressant drugs tested, and by some drugs which had little effect on behavior (diphenhydramine, phenytoin and propranolol), or which caused excitation (caffeine and nialamide). Glycogen was depleted only by amphetaminelike compounds or by bemegride-induced convulsions. The results are discussed with particular reference to the possible relation between catechol amines and glycogen metabolism in the brain.

Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 66357-35-5, Name is Ranitidine, molecular formula is , belongs to benzofurans compound. In a document, author is Das, Purak, SDS of cas: 66357-35-5.

In the present work, a range of phenolic compounds have been reacted with ninhydrin in acid medium to afford different indanone-based molecules via regioselective C-C bond formation. Ninhydrin reacts with 2,7-Dihydroxynaphthalene and 4-cyanophenol in AcOH producing ortho selective adduct 3a and 3b respectively; however, unlike 3a remaining as cyclic hemiketal structure, 3b exists as ring-opened diketo form. On the other hand, ortho-substituted phenols like o-cresol, guaiacol, o-chloro/iodophenol condense with ninhydrin to accomplish para selective diarylated adducts 5a-d, whereas 3-methoxy phenol provides corresponding monoarylated adduct 5e as the major product. Different hydroxy benzoic acids deliver versatile scaffolds like diarylated indanone, indenofuran, benzofuran or spirolactone 7a-e depending upon the substitution pattern and acidity of the reaction medium. All the compounds are characterized by H-1 and C-13 NMR spectra. In the solid state, scissors-shaped molecule 5a has been found to form inclusion complex with disordered o-cresol molecule and function as building unit of supramolecular network. In the crystal structure of spirolactone 7d, anti-parallel motif of dipolar center dot center dot center dot dipolar (C = O(delta-) center dot center dot center dot C(delta+) = O) interaction results ladder-like arrangement.

Related Products of 25834-16-6, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 25834-16-6, 1,3-Isobenzofurandione, 4,7-dibromo, introducing its new discovery.

Three novel conjugated polymers have been designed and synthesized via the alternative copolymerization of the electron-donating monomer benzodithiophene (BDT) and three different electron-accepting monomers: perylene diimide (PDI), naphthalene diimide (NDI), and phthalimide (PhI). All obtained copolymers show good solubility in common organic solvents as well as broader absorptions in visible region and narrower optical band gaps compared to homopolymers from BDT units. It is found that the absorptions of the copolymers are red-shifted with increasing the electron-withdrawing ability of the co-monomer. In particular, the absorption edge of P(BDT-NDI) film extends to 760. nm, whereas that of P(BDT-PhI) film is only at 577. nm. Cyclic voltammograms of the three polymers disclose that P(BDT-PDI) and P(BDT-NDI) are typical n-type materials because PDI and NDI are strong electron-accepting groups, while P(BDT-PhI) is a stable p-type material where the weak electron-withdrawing monomer (PhI) is introduced. The results suggest that the absorption range and the electrochemical properties of the conjugated polymers can be tuned by appropriate molecule-tailoring, which will help exploring ideal conducting polymers for potential applications in polymer optoelectronics, especially in polymer solar cells.

A porous coordination polymer (PCP) has been synthesized employing an organic ligand in which a stable free radical, isoindoline nitroxide, is incorporated. The crystalline PCP possesses one-dimensional channels decorated with the nitroxyl catalytic sites. When O2 gas or air was used as the oxidant, this PCP was verified to be an efficient, recyclable, and widely applicable catalyst for selective oxidation of various alcohols to the corresponding aldehydes or ketones.

Donor-acceptor type (DA-type) polymeric photovoltaic material with a dicarboxylic imide-substituted benzene (phthalimide) derivative as electron-withdrawing units, poly[4,4?-didodecyl-2,2?-bithiophene-co- 5,5?-(3,6-bis(thieno-2-yl)-N-octyl-phthalimide] (PDBTTPT), was synthesized by a Stille coupling reaction. It had an optical band gap of 1.96 V and a relatively low HOMO energy level of -5.34 eV in spite of it being a thiophene-based polymer. Photovoltaic devices with PDBTTPT/PC71BM active layers were fabricated under a variety of conditions for optimizing device performance. PDBTTPT exhibited the best power conversion efficiency (PCE) of 1.5% in the device where 80 wt.% of the PC71BM was contained in the active layer (PDBTTPT:PC71BM = 1:4, w/w) and which was pre-annealed at 120C for 10 min. In addition, a device which was pre-annealed at 140C for 10 min and a device which was post-annealed at 120C for 10 min showed analogous PCE values of 1.5% as well, although small differences were exhibited between various parameters, such as VOC, JSC, and FF.

We report the synthesis and characterization of thienylenevinylene-based donor-acceptor alternating copolymers (PTVPhI-Eh and PTVPhI-C12) as highly efficient ambipolar semiconductors in a thin film transistor. These polymers exhibit significantly improved hole and electron mobilities after thermal annealing. To determine the relationship between ambipolar charge transport and thermal annealing, we investigated these polymers using various analyses such as optical spectroscopy, Raman spectroscopy, computational quantum chemical calculation, X-ray diffraction, atomic force microscopy, and ambipolar charge mobility measurements. In pristine films, the polymer chains exhibited weak intra- and interchain ordering. However, when samples were annealed at sufficiently high temperatures, they exhibited a more ordered intra- and interchain conformation. As a result, we found a strong relationship between intra- and interchain conformational changes of the polymers and corresponding ambipolar charge transport properties during thermal annealing processes. Finally, we demonstrate complementary-like ambipolar inverters using a PTVPhI-Eh polymer. The largely shifted inverting voltage was improved for the thermally annealed inverters, which exhibited large voltage gains (?40).
