Actividad neuroprotectora del aceite esencial de Salvia lavandulifolia Vahl

Abstract

INTRODUCTION Neurodegenerative diseases are becoming more and more common and they represent one of the major public health problems. These diseases are related to oxidative stress, which is caused, among other factors, by an overproduction of free radicals. There are few studies regarding the beneficial effect of essential oil of Salvia lavandulifolia Vahl. (Spanish Sage) on cognitive function, memory and attention in people with dementia and even in the healthy population. In these studies, the effect is mainly ascribed to the capacity to inhibit the acetylcholinesterase and butyrylcholinesterase enzymes, as well as, to their anti-inflammatory, antioxidant and estrogen properties. However, so far it has been not determined a neuroprotective activity based on its antioxidant capacity. OBJETIVE We have evaluated the neuroprotective activity of essential oil from different samples of Salvia lavandulifolia, studying their antioxidant capacity and using for this purpose astrocytes as glial cells,which carry out an important function in the central nervous system. METHODOLOGY The essential oil extracted was studied by gas chromatography to determine its composition. Its effect on survival, proliferation and cytotoxicity in cells was quantitatively evaluated using the technique of bromide 3 - (4, 5-dimethylthiazol-2-yl) -2,5-difeniltetrazol (MTT), just as its protective effect against toxic (H2O2). The intracellular generation of free radicals was also measured using dichlorofluorescein (DCFH-DA) technical as well as the ability of essential oil to reduce free radicals production induced by hydrogen peroxide. CONCLUSION /DISCUSSION The main components of the samples studied are: 1.8-cineole, camphor and α-pinene. The essential oil of S. lavandulifolia exerts a protective effect on astrocytes against hydrogen peroxide, increasing significantly viability of cells under oxidative stress conditions. None of the samples generated free radicals on the cell line of the study as dichlorofluorescein technique showed. The essential oil also demonstrated a slight free radical scavenger capacity.

INTRODUCCIÓN: El advenimiento de la biología molecular ha agregado una nueva dimensión al proceso de descubrimiento de nuevos fármacos dirigidos hacia el concepto de las terapias avanzadas donde medicamentos clásicos coexistirán con células madre, genes y tejidos transformados ex vivo. Existen muchos tipos de células madre y todos ellos comparten las características de ser capaces de renovarse y dar lugar a progenie diferenciada. El presente trabajo, compara y reflexiona sobre el desarrollo farmacéutico de un medicamento convencional con un medicamento celular. Ambos presentan la misma forma de dosificación, suspensión de un principio activo: de síntesis para el medicamento convencional y células para el medicamento celular; en un medio acuoso, contenido en una jeringa como acondicionamiento primario. METODOLOGÍA: La fabricación de inyectables requiere de más cuidados que cualquier otra forma farmacéutica clásica debido a su vía de administración. Un inyectable debe cumplir, entre otras, con las siguientes características: isotonía, ausencia de pirógenos, y de esterilidad. Sin embargo en la preparación de una suspensión celular, el producto final no puede ser esterilizado, ya que las células deben ser viables para poder mantener sus características terapéuticas. La esterilidad del medicamento celular, deberá ser aportada en el proceso de producción, clase A sobre un entorno clase B. CONCLUSIÓN / DISCUSIÓN: Los métodos de preparación y control de inyectables convencionales son procedimientos que no pueden utilizarse en el medicamento celular ya que dichas técnicas son incompatibles con la viabilidad de células mesenquimales, por lo que el método de elaboración del activo celular para la misma forma de dosificación debe realizarse en condiciones controladas. Así pues el desarrollo galénico de ambos medicamentos difiere y deberá ser considerado en cuanto a la tecnología farmacéutica se refiere.
