Equilibrium constants have been determined for the formation of 15 different zirconocene monomethyl monochloro complexes from the respective dichloride complexes and AI2 (CH3)6' The results indicate that the tendency of a particular zirconocene complex to exchange a chloride against a methyl ligand is a measure for the electron deficiency at its Zr center. The results indicate particularly low ...
As theophylline is known to stimulate lipolysis and lipid mobilisation, plasma concentrations of malonyl dialdehyde were studied in asthmatic patients being treated with sustained release theophylline. Malonyl dialdehyde was assessed as malonyl dialdehyde like material (MDA-LM) by the thiobarbituric acid assay. In a kinetic study (eight patients) plasma MDA-LM concentrations were found to be si...
The American diet, especially that of adolescents, contains highly palatable foods of high-energy content and large amounts of high-fructose sweeteners. These factors are believed to contribute to the obesity epidemic and insulin resistance. Previous investigations revealed that the central metabolism of glucose suppresses food intake mediated by the hypothalamic AMP-kinase/malonyl-CoA signalin...
Radioactive waste management is a modern-day issue in terms of radiation safety due to the development radionuclide therapy, emergence new radiopharmaceuticals, radionuclides, and treatment methods, which allow for therapy day hospital. According current domestic regulatory methodological support biological wastes generated during patient’s metabolic activity after injection radiopharmaceutical...
Acetyl-CoA carboxylase (ACC; EC 6.4.1.2) catalyses the formation of malonyl-CoA, which is essential as a metabolic substrate and as a modulator of specific protein activity. Malonyl-CoA is a substrate for fatty acid synthase (FAS), for polyketide synthases (in plants, fungi and bacteria) and for fatty acyl chain-elongation systems. As an allosteric modulator, malonyl-CoA potently inhibits carni...
The base-switched annuloselectivity, namely [2 + 2] and [2 + 2 + 2] selectivity, in the reactions of ethyl malonyl chloride and imines is successfully realized. In the presence of the weak nucleophilic base 2-chloropyridine, the reactions deliver ethyl trans-β-lactam-3-carboxylates as the exclusive [2 + 2] products in up to 93% yields, while with the strong nucleophilic N-methylimidazole as the...
