Copper-catalyzed Addition Reactions of Aromatics and Ketones to 2-Aza-2,4-cyclopentadienone: Facile and Efficient Transformation of Carbonyl-ene-nitriles to 1H-Pyrrolin-2(5H)-ones

Copper-catalyzed reactions of carbonyl-ene-nitriles with carbon nucleophiles, such as aromatics and ketones, afforded pyrrolin-2-ones (gamma-lactam) in excellent yield. The reaction mechanism involves addition reactions with a ketimine moiety of the 2-aza-2,4-cyclopentadienone intermediate, which is formed via hydration of a nitrile moiety followed by dehydrative cyclization.

EFFECTS OF MYOSMINE ON ANTIOXIDATIVE DEFENCE IN RAT LIVER

Myosmine [3-(1-pyrrolin-2-yl) pyridine] is an alkaloid structurally similar to nicotine, which is known to induce oxidative stress. In this study we investigated the effects of myosmine on enzymatic and nonenzymatic antioxidative defence in rat liver. Wistar rats received a single i.p. injection of 19 mg kg(-1) of myosmine and an oral dose of 190 mg kg(-1) by gavage. Nicotine was used as a positive control. Through either route of administration, myosmine altered the hepatic function by decreasing the levels of reduced glutathione, superoxide dismutase, and glutathione peroxidase activities on one hand and by increasing malondialdehyde, catalase, and glutathione reductase activity on the other. Compared to control, both routes caused significant lipid peroxidation in the liver and altered hepatic enzymatic and non-enzymatic antioxidative defences. The pro-oxidant effects of myosmine were comparable with those of nicotine.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 611-64-3 help many people in the next few years. Reference of 611-64-3.

An EPR study of wheat seeds by the use of nitroxide spin probes

The viability of a variety of wheat seeds Mas investigated by use of the EPR technique, Three different types of spin probes (4-Hydroxy-TEMPO (TANOL), 3-Carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy, 3-Carbamoyl-PROXYL) were utilized in examining the viability of embryo cells. The penetration of the spin probe across the membrane was observed via the change in signal intensity against time for dry embryos of the variety of wheat seeds soaked in aqueous solutions of spin probe and line broadening agent. From the analysis of the signal intensity-time curves (i.e. rehydration curves) it was observed that the two kinds having different genetic roots (Bezostaya, Kunduru) exhibit similar saturation behaviour whereas Gerek saturates much more easily. The rehydration curves for naturally aged seeds indicates that aging causes rapid saturation and an important decrease in the signal intensity. In order to get better insight on the effect of the signals from polar and nonpolar regions on the experimental spectra, these spectra were simulated by the use of the theoretical models developed.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 56353-15-2. Name: (S)-2-(3-Acetamidopropanamido)-3-(1H-imidazol-4-yl)propanoic acid.

Cross-Linking of Rubber Matrices with Dicumyl Peroxide and Zinc Dimethacrylate. Part I: Effect of Co-Agent Content

The work is focused on the investigation of the influence of the amount of co-agent on cross-linking and properties of rubber compounds. The in-situ radical polymerization of zinc dimethacrylate occurs during the curing process of rubber compounds with organic peroxide. Polymerized zinc dimethacrylate tends to form different types of chemical and physical linkages within the rubber matrices. As the amount of dimethacrylate ranged from 10 to 50 phr, the conversion of zinc dimethacrylate remained low. Residual zinc dimethacrylate formed micro-dispersion in the rubber matrix. The dispersion and distribution of zinc dimethacrylate in the rubber depends on the viscosity of matrix, shear stress and polarity of the matrix. Despite low conversion of zinc dimethacrylate, the application of co-agent resulted in the increase of cross-link density and improvement of physical-mechanical properties of vulcanizates.
