Inhibitors of the fungal cell wall. Synthesis of 4-aryl-4-N-arylamine-1-butenes and related compounds with inhibitory activities on β(1-3) glucan and chitin synthases

Description: As part of our project devoted to the search for antifungal agents, which act via a selective mode of action, we synthesized a series of new 4- aryl- or 4-alkyl-N-arylamine-1-butenes and transformed some of them into 2- substituted 4-methyl-tetrahydroquinolines and quinolines by using a novel three-...

Initiation of DNA replication at CpG islands in mammalian chromosomes

Description: CpG islands are G + C-rich regions ~ 1 kb long that are free of methylation and contain the promoters of many mammalian genes. Analysis of in vivo replication intermediates at three hamster genes and one human gene showed that the CpG island regions, but not their flanks, were present in very short ...

In Schizosaccharomyces pombe chs2p has no chitin synthase activity but is related to septum formation

Description: El pdf del artículo es la versión post-print. , Chitin synthesis occurs in most fungi through the action of different chitin synthase (CS) isoenzymes. In Schizosaccharomyces pombe the chs2+ gene codes for a protein with significant similarity to CS enzymes, but lacking most of the residues considered t...

Mitochondria are an early target of oxidative modifications in senescing legume nodules

Description: 39 Pags., 4 Tabls., 8 Figs. The definitive version is available at: http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1469-8137 , Legume nodule senescence is a poorly understood process involving a decrease in N2 fixation and an increase in proteolytic activity. Some physiological changes during no...

La cuestión de la frecuencia y el tipo de trato con inmigrantes: una aproximación a los efectos de las relaciones intergrupales sobre las actitudes hacia la inmigración

Description: The goal of this report is to look in more depth at the effects that the relationships between indigenous people and immigrants can have on the attitudes of the former towards the latter. The study uses the results of a national opinion poll on the perception of Spaniards towards immigration. Follow...

Interactions of the RNA polymerase with the viral genome at the 5′- and 3′-ends contribute to 20S RNA narnavirus persistence in yeast

Description: 20S RNA narnavirus is a positive strand RNA virus found in the yeast Saccharomyces cerevisiae. The viral genome (2514 nucleotides) only encodes a single protein (p91), the RNA-dependent RNA polymerase and does not have capsid proteins to form intracellular virions. The genomic RNA has no 3′ poly(A) ...

Dependence of the unimolecular dissociation products on the fluence of the CO2 laser beam

Description: The dissociation products of CF2Cl2 irradiated in the line P20 at 9.17 μm with pulses of fluence as high as 60×104 J.m-2 depend on the pressure of the gas, giving rise to C2F4 only when the pressure is of the order of 2 mb. Ar remarkably lower fluence ( 2×104 J.m-2) this product appears however in a...

Quantitative Real-time PCR versus culture: a Comparison between two methods for the detection and quantification of Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis and Tannerella forsythensis in subging ...

Description: 9 páginas, 3 figuras, 5 tablas -- PAGS nros. 1061-1069 , Objective: To develop a method for quantification of Actinobacillus actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg) and Tannerella forsythensis (Tf) from subgingival plaque samples based on TaqMan real-time polymerase chain reaction (PC...

A study of the tautomerism of β-dicarbonyl compounds with special emphasis on curcuminoids

Description: Six β-diketones related to curcumin and curcumin itself have been studied by 13C NMR spectroscopy in chloroform in order to determine the equilibrium constant between the two keto/enol tautomers. In order to do this GIAO/B3LYP/6-31G** calculations of absolute shieldings (σ, ppm) were carried out. To...
