(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 ...
