A convenient approach to novel symmetric bispyrimidine diamines comprises SNAr reactions of 4-fluoropyrimidine N-oxide with alkane-α,ω-diamines with subsequent reduction of N-oxide function. The obtained substances were tested in patch-clamp experiments for the influence on the kainateinduced currents in Purkinje neurons and showed negative modulating effect.相似文献
A convenient synthesis of Fucα1-2Galβ1-3GalNAcβ-OCH2CH2CH2NH2 (trisaccharide H type 4) is described. This glycan is the terminal part of glycosphingolipids globo-H and fucosyl-GM1 known as cancer-associated carbohydrate antigens. 相似文献
Boiling intensifies the radiolytic conversion of diglyme since it stimulates the cleavage of the C–O bonds in the excited molecules and the primary radical cations, enhances the radical exchange reactions, and weakens the diglyme regeneration reactions.
One of the most promising among hole-conducting materials, CuSCN, was prepared for the first time in a form of porous layers for potential applications in inverted perovskite solar cells. 相似文献
The magnetic composite SrFe10.7Al1.3O19/Co was synthesized by ethylene glycol reduction of cobalt ions on the surface of hexaferrite particles dispersed in the solvent. The resulting material contained magnetically hard submicron hexaferrite particles covered by soft magnetic cobalt nanoparticles. The composite demonstrated the exchange-coupling effect between hard and soft magnetic phases. 相似文献
The upper limit of the amount of copper ions that can be grafted to the detonation nanodiamond surface has been calculated. A maximum of 34 wt% copper can be grafted to carboxylated and hydroxylated 5 nm nanodiamonds. The results of calculations have been compared with the experimental and published data. 相似文献
