Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (2S)-(+)-3-Chloropropane-1,2-diol, is researched, Molecular C3H7ClO2, CAS is 60827-45-4, about The selective neurotoxicity produced by 3-chloropropanediol in the rat is not a result of energy deprivation.Related Products of 60827-45-4.

The biochem. mechanism of toxicity of the exptl. astrocyte neurotoxicant and food contaminant S-3-chloro-1,2-propanediol (3-CPD) has been proposed to be via inhibition of glyceraldehyde-3-phosphate dehydrogenase (GAPDH). We have confirmed this action in liver, which shows inhibition to 6.0±0.7% control at the neuropathic dose of 140 mg/kg. However, GAPDH activity in brain only fell to a min. of 54±24% control, and the concentrations of lactate and pyruvate (the downstream products of GAPDH), showed no pre-neuropathic decreases in 3-CPD susceptible brain tissue. There was no inhibition of GAPDH activity in primary astrocyte cultures at sub-cytotoxic exposures. We therefore sought alternative mechanisms to explain its toxicity to astrocytes. We were able to show that 3-CPD is a substrate for glutathione-S-transferase and also that, after bioactivation by alc. dehydrogenase, it generates an irreversible inhibitor of glutathione reductase. In addition, incubation of brain slices from the 3-CPD-vulnerable inferior colliculus produces a depletion of glutathione and an inhibition of glutathione-S-transferase that is not seen in equivalent slices taken from the 3-CPD-resistant occipital neocortex. A smaller but significant and similarly regionally selective decrease in glutathione content is also seen in vivo. We conclude that 3-CPD does not produce its astrocytic toxicity via energy deprivation, and suggest that selective bioactivation and consequent disruption of redox state is a more likely mechanism.

Formula: C6H8N2. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 2-Methylglutaronitrile, is researched, Molecular C6H8N2, CAS is 4553-62-2, about New solvent for aromatics separation. Author is Feldman, Julian.

1,3-Dicyanobutane (derived from acrylonitrile) has a higher capacity for light aromatic hydrocarbons in liquid-liquid extraction than does sulfolane. As a solvent in extractive distillation its low volatility, high thermal stability, low f.p. and high selectivity are useful. Equilibrium data and multistage extractions of a typical light catalytic reformate are reported. A light counter-solvent is effective, especially when followed by extractive distillation A combination of methods gives high purity aromatics or improved octane gasoline. A flow diagram is given for continuous cyclic operation to sep. reformate and recover the solvent.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 60827-45-4, is researched, SMILESS is OC[C@H](O)CCl, Molecular C3H7ClO2Journal, International Journal of Andrology called Inhibition of glucose catabolism in rat, hamster, rhesus monkey and human spermatozoa by α-chlorohydrin, Author is Ford, W. C. L.; Harrison, Anne; Takkar, G. L.; Waites, G. M. H., the main research direction is sperm glucose metabolism chlorohydrin; glycolysis sperm chlorohydrin.Electric Literature of C3H7ClO2.

Spermatozoa from the cauda epididymis of rats treated with RS-α-chlorohydrin [96-24-2] (10 mg/kg/day for 7 days, orally) had the same ATP [56-65-5] content as control spermatozoa immediately after collection, but were unable to metabolize glucose [50-99-7] in vitro and so their ATP content declined more rapidly than that of control spermatozoa. The in vitro metabolism of glucose by spermatozoa from rat, hamster, rhesus monkey, and human was inhibited by ≥80% after 15-30 min preincubation in the presence of RS-α-chlorohydrin concentrations of <1, >10, 5-10, and >50 mM, resp. Inhibition of glucose oxidation was correlated with a reduction in ATP concentration in the spermatozoa. α-Chlorohydrin may act as an antifertility agent by inhibition of sperm glycolysis, but RS-α-chlorohydrin would apparently not be an effective contraceptive in man. However, the glucose metabolism of human spermatozoa was significantly inhibited by <10 mM of S-α-chlorohydrin [60827-45-4].

The authors report a new synthesis of size-controlled bimetallic Ru-Cu nanoparticles (NPs) in ionic liquids using two organometallic precursors. Enough, upon mixing ruthenium and copper precursors, smaller bimetallic NPs (1.9-2.8 nm) are formed as compared to single metals (Cu: 5 nm; Ru: 4 nm) in a large range of copper molar fractions (χCu = 0.005-0.91). Surface and microscopy techniques evidence that NPs have metallic copper on the surface and crystalline hcp. metallic ruthenium core. This structure is further assessed by the catalytic activity of the bimetallic NPs, showing that conversion of benzene in cyclohexane is reduced with increasing χCu.

Quality Control of Mesitylcopper(I). 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: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about In situ Catalytic Generation of Allylcopper Species for Asymmetric Allylation: Toward 1H-Isochromene Skeletons. Author is Kawai, Junya; Chikkade, Prasanna Kumara; Shimizu, Yohei; Kanai, Motomu.

Allylcopper species can be generated in situ via catalytic intramol. oxycupration of allenic alc. The allylcopper can react with various aldehydes and a ketone to give 1H-isochromene derivatives enantioselectively. The protocol is atom-economical, highly regioselective, stereoconvergent, and tolerant to free OH groups. Thus, e.g., enantio- and regioselective oxycupration/asym. addition cascade reaction of allenic alc. I with benzaldehyde in presence of mesitylcopper and chiral diphosphine ligand in HMPA/THF afforded isochromene II (98% yield, 92% ee).

Reaction of copper(I) mesityl with [Ba(OtBu)2(t-BuOH)2]4 yields insoluble [BaCu2(OtBu)4]n, which dissolves by adduct formation (L = Me3NO or Et3PO) to form soluble L2Ba2Cu4(OtBu)8. For L = Me3NO, this mol. is shown by x-ray diffraction to have a structure based on a trans-Ba2Cu4 octahedron, with all Ba/Cu edges bridged by μ2-OtBu units; one L binds to each Ba (monoclinic, space group P21/c, R = 0.0822). Bulk thermolysis, TGA, and product anal. revealed that OtBu units undergo not only O/C cleavage but also C/C cleavage, the latter to form carbonate and nonvolatile hydrocarbon products, in addition to BaO and CuO. The intended oxidant Me3NO shows no great tendency to oxidize Cu(I).
