(1992)The crystal and molecular structure of bis-(N-phenyl-1-hydroxy-2-naphthylaldiminate) nickel(II) (1) have been determined by x-ray crystallography. The compound crystallizes in the triclinic space group P1, No. 2 with one ...
-
(IOS Press, 2020)Background: Alzheimer's disease (AD) is a multifactorial disease, that involves neuroinflammatory processes in which microglial cells respond to "damage signals". The latter includes oligomeric tau, iron, oxidative free ...
-
(Sociedad Chilena de Quimica, 1999)The N-acylation reaction of a series of lactams of biological interest, derived from 2-benzoxazolinones and 1,4-benzoxazin-3-one, with acetic anhydride has been studied. The reaction yields show the same tendency as that ...
-
(2016)A new and efficient synthesis of 2-arylbenzoxazoles and benzothiazoles using a copper N-heterocyclic carbene complex is described. In a simple protocol a variety of 2-substituted benzoxazoles and benzothiazoles were obtained ...
-
(2009)The crystal structure of N-methyl-1H-indole-2-carboxamide C10H10N2O was determined by single crystal X-ray diffraction. The structure can be described as consisting of an indole group and as substituent, linked at C2, the ...
-
(Sociedad Chilena de Química, 2006)Benzyltetrahydroisoquinoline (BTHIQ) molecules are able to adopt widely differing conformations that depend on the presence or absence of N-substituents. To assess the possible role of BTHIQ conformation on the affinity ...

-
(1990)An NADP+-dependent D-xylose dehydrogenase from pig liver cytosol was purified about 2000-fold to apparent homogeneity with a yield of 15% and specific activity of 6 units/mg of protein. An M(r) value of 62000 was obtained ...
-
(Lippincott Williams and Wilkins, 2001)In vertebrate olfactory receptor neurons, NO synthase (NOS) has been detected in embryonic and early postnatal stages. However, expression of the enzyme in the mature epithelium is still controversial. We analyzed the ...
-
(Springer, 2010)In this work, the modification of a glassy carbon electrode with tetraruthenated porphyrins electrostatically assembled onto a Nafion film, previously adsorbed on the electrode surface, is reported. This modified electrode ...
-
(AMER CHEMICAL SOC, 2006-06-27)We report the observation of urchin-like nanostructures consisting of high-density spherical nanotube radial arrays of vanadium oxide nanocomposite, successfully synthesized by a simple chemical route using an ethanolic ...
-
(2012)Collision processes between single gold and rhodium atoms and gold and rhodium nanoclusters, respectively, are used to study the interplay between the large elastic energies and the much smaller magnetic interactions. The ...
-
(Sociedad Chilena de Química, 2017)Single crystals of 1,3-bis(cyanomethoxy)calix[4]arene (1) were grown from Chloroform/Methanol mixture and these were nanodecorated with colloidal gold nanoparticles (AuNps). The single crystals were then characterized by ...
-
(Elsevier, 2020)Polycrystalline hollow nanoparticles present a unique combination of strength and flexibility. However, the exact role displayed by their grain structure in mechanical properties has not been yet fully understood. Here, ...
-
(Elsevier, 2016)In this work, we have studied the Pb2+ sorption capacity of Zeolite (Z) and Montmorillonite (Mt) functionalized with nanoscale zero-valent iron (nZVI), at 50% w/w, obtained by means of an impregnating process with a solvent ...
-
(2011)Pyrolysis of molecular precursors containing vanadium organometallic and cyclic phosphazene affords mixtures of nanostructured vanadium oxides and pyrophosphates. The products from the molecular precursor [N3P3(OC6H5)5OC ...
-
(Elsevier Ltd., 2009-02-08)A series of naphthylisopropylamine and N-benzyl-4-methylthioamphetamine derivatives were evaluated as monoamine oxidase inhibitors. Their potencies were compared with those of a series of amphetamine derivatives, to test ...
-
(2014)In this paper, an aspect of the national discourse of the early twentieth century in the territory of Tacna and Arica, in its sovereignty dispute between Chile and Peru, is analyzed. The corpus of the analysis focuses on ...
