Nanomedicamentos para el tratamiento localizado de patologías pulmonares

Abstract

El objetivo de la presente memoria se ha dirigido al diseño y evaluación de nanoestructuras para el tratamiento localizado de patologías pulmonares. En una primera etapa, se han desarrollado nanopartículas de quitosano, en combinación con ácido hialurónico o con carboximetil-β-ciclodextrina, conteniendo la macromolécula hidrofílica heparina, con la finalidad de comprobar su eficacia en el tratamiento del asma bronquial. Se demostró por microscopía confocal de fluorescencia que los nanosistemas eran internalizados por mastocitos de rata y, en el caso de los nanosistemas con ciclodextrinas, se consiguió mejorar de manera significativa el efecto de la heparina sobre la inhibición de la liberación de histamina en mastocitos. La segunda parte del trabajo se dirigió al diseño de un nuevo nanosistema, consistente en nanocápulas de ácido hialurónico, con el fin último de dirigirlo al tratamiento del cáncer de pulmón. Los nanosistemas incrementaron significativamente el efecto citotóxico del antitumoral hidrofóbico docetaxel, sobre la línea celular de cáncer de pulmón NCI-H460, hecho que se atribuyó a la internalización de las nanocápsulas y la liberación intracelular del docetaxel. Estos resultados resaltan el enorme interés de los nanosistemas desarrollados para la liberación intracelular de fármacos en el tratamiento de enfermedades pulmonares.
