Valproic Acid,a Drug with Multiple Molecular Targets Related to Its Potential Neuroprotective Action

Valproic acid (VA) is used worldwide as an antiepileptic drug and a mood stabilizer. Recently, VA was shown to act on cell growth, differentiation and apoptosis, by regulating gene expression at the molecular level, through epigenetic mechanisms. Thus, VA was demonstrated to act on the chromatin remodeling what is a consequence of the drug inhibition of histone deacetylases (HDACs) activity. Other studies uncovered the potential of VA to interfere with multiple regulatory mechanisms besides HDACs, as the GSK3 alpha and beta, Akt, ERK and phosphoinositol pathways, tricarboxylic acid cycle, GABA and OXPHOS system. The review focuses on the mechanisms of action of VA, showing that HDAC inhibitors, as VA, can be successfully used in the treatment of neurodegenerative disorders. This molecule, whose biological activities range from interactions with receptors and ion channels to the regulation of many catalytic reactions, has a central role in cellular cascades that regulate gene expression. Thus, inhibitors of HDACs, by positively affecting both neuronal degeneration and cognitive deficits, appear as promising drugs against various pathological conditions and neurodegenerative diseases. VA is known to present anti-inflammatory and antioxidative properties. And, since inflammation and oxidative stress are common links in neurodegeneration, VA is a drug that, from a clinical point of view, shows a great potential as a candidate for the treatment of neurodegenerative diseases related to excitotoxic events.

Nutrients Available and Stable Carbon from Archaeological Black Earth

Journal of Environmental Protection 2021年第11期12卷 873-886页

作者： Antônio Roberto de Oliveira Meireles Vanda Porpino Lemos Orivan Maria Marques Teixeira Kelly das Graças Fernandes Dantas Dantas Marcelly christian Galvão Rodrigues machado Milena Carvalho de Moraes School Tenente Rego Barros Bel&eacute m Brazil College of Chemistry Institute of Exact and Natural Sciences Federal University of Par&aacute Bel&eacute m Brazil Soil and Plant Laboratory Brazilian Agricultural Research Corporation Bel&eacute m Brazil Coordination of Earth Sciences and Ecology Emílio Goeldi Museum of Par&aacute Bel&eacute m Brazil

The present study aims affinity between available concentrations of phosphorus, micronutrients (Cu, Zn and Mn) and stable carbon (SC) in archaeological black earth (ABE) from area “Ilha de Terra”/Caxiuanã—Pará. The relevance of this study refers especially to the determination of carbon concentrations (total, oxidable and semi-labile carbon) directly associated with those of pyrogenic carbon, common in ABE, which should add their contributions to the understanding of soil organic matter recalcitrance. Chemical properties such as CEC and base saturation were determined for ABE and subjacent Latossoil. The available concentrations of nutrients were performed from sequential extraction F1 to F5 phases. Phosphorus was obtained by spectrophotometric method and micronutrients by MP-AES. TOC was determined by the combustion method;stable carbon was obtained from thermoxidation method CTO-375. The following results were obtained from ABE: CEC effective = 21 to 28 (cmolc·L-1);base saturation = 58% to 69%;Carbon concentrations (%): TOC = 2.95 to 3.94;SC = 0.25 to 0.88;semi-labile carbon = 1.75 to 3.63;oxidable = 2.11 to 3.65;inorganic carbon 0.01 to 0.38;P2O5 concentrations (mg·kg-1) in the ABE phases F3 (Fe-Mn oxides, F4 (organic ) and F5 (residual)) in the following order: 35 to 65;200 to 400;140 to 230. It was concluded that the chemical properties in ABE from Ilha de Terra site fall within the range of fertile and the high concentrations of phosphorus are biogenic origin. Phases F3 and F4 are those considered nutrient stocks from ABE studied area.
