Actividad antiproliferativa y anticolesterogénica de estatinas y monoterpenos

Abstract

Las estatinas son inhibidores competitivos de la HMG-CoA reductasa ampliamente usados en los tratamiento contra las hipercolesterolemias. Los monoterpenos son componentes no nutritivos de la dieta presentes en aceites esenciales de varias plantas que han demostrado tener múltiples efectos en la vía del mevalonato. Se estudia el efecto y mecanismo de acción de monoterpenos presentes en aceites esenciales, así como la combinación de éstos entre sí y con simvastatina sobre la síntesis de colesterol, el metabolismo lipídico y la proliferación celular "in vitro" en células hepáticas Hep G2 y no hepáticas A549, e "in vivo" en ratones atímicos huéspedes y no huéspedes de tumores derivado de células A549 implantados en ellos. Se abre así una gran expectativa sobre la potencialidad de la administración conjunta de distintos monoterpenos y de extractos naturales de aceites esenciales en el mejoramiento de las terapias antihipercolesterolemiantes y/o el tratamiento del cáncer, como así también en el potencial sinergismo con estatinas como una alternativa para disminuir las dosis efectivas y los efectos indeseados y/o tóxicos.

As estatinas são inibidores competitivos da 3-hidroxi-3-metilglutaril - coenzima A (HMG-CoA) reductase amplamente utilizados nos tratamentos contra as hipercolesterolemias. Os monoterpenos são componentes não nutritivos da dieta encontrados em óleos essenciais de várias plantas que demonstraram ter múltiplos efeitos na via do mevalonato. Estudamos o efeito e o mecanismo de ação de monoterpenos encontrados em óleos essenciais, bem como a combinação deles entre si e com sinvastatina sobre a síntese de colesterol, o metabolismo lipídico e a proliferação celular in vitro em células hepáticas Hep G2 e não hepáticas A549 e in vivo em camundongos atímicos hospedeiros ou não hospedeiros de tumores derivados de células A549 implantadas neles. Isto abre grandes expectativas sobre o potencial da co-administração de diferentes monoterpenos e de extratos naturais de óleos essenciais na melhoria das terapias anti-hipercolesterolemiantes e/ou tratamento do câncer, assim como no potencial sinergismo com estatinas como uma alternativa para reduzir as doses efetivas e os efeitos indesejáveis e/ou tóxicos.

Statins are competitive inhibitors of HMG-CoA reductase used in hypercholesterolemic patients. Monoterpenes are non-nutritive dietary components found in the essential oils of many plants with pharmacologic effects on mevalonate metabolism. The study is centered on the effects and action mechanisms of the monoterpene components of essential oils and the combination of monoterpenes between them and combined with simvastatin on cholesterogenesis, lipid metabolism and cellular proliferation in vitro using two established cell lines, Hep G2 (derived from a human hepatoblastoma), A549 (derived from a human lung adenocarcinoma) and in vivo in no host and host nude mice carrying implanted tumors derived from A549. This opens up great expectations about the potential of co-administration of different natural isoprenoids and essential oils in improving anti-cholesterolemic therapies and/or cancer treatment as well as in the potential synergism with statins as an alternative to lower effective doses, decreasing the likelihood of undesired and/or toxic effects.
