Detailed studies of properties of new 3-substituted 5-anilino-1,2,4-thiadiazoles containing different substituents at position 3 of the thiadiazole ring were carried out, in particular, their esterase profile and antioxidant properties. It was found that the presence in the molecule of 2-aminopropyl fragment determines an efficient and selective inhibition of butyrylcholinesterase as compared to acetylcholinesterase and carboxylesterase, with radical-scavenging activity being weak. The compounds containing a 2-aminopropenyl fragment possess a high radicalscavenging activity, weakly inhibit cholinesterases, and exhibit anticarboxylesterase activity. A wide spectrum of activity of 3-substituted 5-anilino-1,2,4-thiadiazoles as inhibitors of cholinesterases and highly efficient scavengers of free radicals gives a basis for the optimization of structure and development in this series of original agents for therapy of neurodegenerative diseases. 相似文献

External electric field effect on electronic properties and charge transfer in CoI2/NiI2 spinterface
Iuliia Melchakova Evgenia A. Kovaleva Natalia S. Mikhaleva Felix N. Tomilin Sergey G. Ovchinnikov Alexander A. Kuzubov Paul Avramov 《International journal of quantum chemistry》2020,120(3):e26092
Electronic structure and spin-related properties of CoI2/NiI2 heterostructure were studied by means of density functional theory. It was shown that the electronic structure at the Fermi level can be characterized by a band gap. The effect of the external electric field on charge transfer and electronic properties of the CoI2/NiI2 interface was investigated, and it was found that band gap width depends on the strength of the applied electric field, switching its nature from semiconducting to a half-metallic one. An easy control of the electronic properties and promising spin-polarized nature of the CoI2/NiI2 spinterface allows the heterostructure to be used in spin-related applications. 相似文献

We study the effect of gallium-containing aqueous solutions on polycrystalline aluminum. The procedure for kinetic studies of the selected system is described. It is found that in the reaction of polycrystalline aluminum with gallium-containing aqueous solutions, gallium penetrates along the aluminum grain boundaries, which, upon the application of external stress, leads to failure of the sample. It is found that gallium can penetrate along the aluminum grain boundaries both in the liquid and solid state; the rates of penetration of gallium in the liquid and solid states are determined. 相似文献

Diphenylphosphinoylallenes containing a ClCH2 group were synthesized, and their reaction with cytisine was studied. It was shown that the reaction involves exclusives as nucleophilic substitution of chlorine in the chloromethyl group. The synthesized conjugates of cytisine with diphenylphosphinoylallene derivatives are of interest as potential agonists of nicotinic acetylcholine neuroreceptors (nAChRs). 相似文献

The crystal structure of L-leucinium tetrafluoroantimonate(III) of the composition (C6H14NO2)SbF4 (orthorhombic symmetry: a = 6.1459(6) Å, b = 14.994(1) Å, c = 24.789(2) Å, Z = 8, P 212121 space group) synthesized for the first time is determined. The (C6H14NO2)SbF4 structure represents a new structure type of tetrafluoroantimonate(III). It is formed by (C6H14NO2)+ cations and chain complex [Sb2F8]n 2n anions composed of Sb2F8 dimers linked into chains by bridging F atoms. The Sb2F8 dimers consist of SbF3 and SbF5 groups bound by bridging fluoride atoms of the SbF5 group. Chains in the structure are linked by N-H…F, N-H…O, and O-H…F hydrogen bonds into a three-dimensional framework. 相似文献
