The title complex, [Cd(C(6)H(17)N(3))(2)](ClO(4))(NO(3)), was synthesized by the reaction of Cd(NO(3))(2)·4H(2)O, bis-(3-amino-prop-yl)-amine and sodium perchlorate in methanol. The asymmetric unit of the title complex consists of one Cd(2+) cation, two tridentate bis-(3-amino-prop-yl)amine ligands, one nitrate anion and one perchlorate anion. The Cd(2+) cation is coordinated by six N atoms of ...
The formation of gold nanoparticle–lipid composite films by glucose-induced reduction of chloroaurate ions entrapped in thermally evaporated fatty amine films is described. Simple immersion of films of the salt of octadecylamine and chloroaurate ions (formed by immersion of thermally evaporated fatty amine films in chloroauric acid solution) in glucose solution leads to the facile in-situ reduc...
The carcinogenicity of five derivatives of nitrosodiethylamine was compared with that of the parent compound by p.o. administration to rats. All were less potent than was nitrosodiethylamine. When nitrosobis(2-methoxyethyl)amine and nitrosobis(2-ethoxyethyl)amine were administered at equimolar doses in drinking water, there was a high incidence of liver tumors, but the animals died later than t...
to develop a new more accurate spectrophotometric method for detecting monoamine oxidase inhibitors from plant extracts, a series of amine substrates were selected and their ability to be oxidized by monoamine oxidase was evaluated by the hplc method and a new substrate was used to develop a peroxidase-linked spectrophotometric assay. 4-(trifluoromethyl) benzylamine (11) was proved to be an exc...
one-pot reaction of aldehydes or ketons with aniline derivatives was performed using nabh4 and fe3o4 magnetic nanoparticles (mnps). the optimum amount of fe3o4 mnps was 5 mol% under solvent free condition. the corresponding products were obtained in good to excellent yields. the magnetically recoverable iron oxide nanoparticles are found to be efficient for synthesis of amine derivatives. these...
When cultures of Escherichia coli are partially inhibited by sulfonamides they accumulate a diazotizable and nonacetylable amine in the medium (Fox, 1942). The amine was isolated by Stetten and Fox (1945) and characterized by Shive et al. (1947) as 4-amino-5-imidazole carboxamide. The latter authors suggested that the amine was a precursor of purines as it only required the addition of a one ca...
We report here the crystal structure of a ten-coordinate lanthanum(III) metal coordinated by five bidentate ethyl-enedi-amine ligands, [La(C2H8N2)5]Cl3·C2H8N2·CH2Cl2. One free ethyl-enedi-amine mol-ecule and three Cl(-) anions are also located in the asymmetric unit. The overall structure is held together by an extensive hydrogen-bonding network between the Cl(-) anions and the NH groups on the...
The potent antihypertensive drug reserpine inhibits the transport of biogenic amines into adrenal chromaffin granules and synaptic vesicles. Reserpine acts by binding almost irreversibly to the vesicular amine transporter, and this interaction has been used both to study the mechanism of transport and to purify the protein responsible. Recent isolation of a cDNA for the rat chromaffin granule a...
