Quitosanos sulfatados. De sus propiedades estructurales a sus actividades biológicas

Abstract

[ES] El quitosano es un polisacárido semisintético derivado de la quitina, el segundo biopolímero más abundante en la naturaleza. Entre sus numerosas propiedades el quitosano es biodegradable, biocompatible y no tóxico y, además, presenta actividades biológicas muy variadas (analgésica, antitumoral, antimicrobiana, antiviral, antiinflamatoria, etc). La funcionalización del quitosano es un área de investigación emergente en el diseño de soluciones para una amplia gama de aplicaciones biomédicas. En particular, la modificación del quitosano con grupos sulfato ha generado un gran interés debido a que dicha modificación proporciona nuevas y atractivas propiedades físico-químicas en comparación al quitosano de partida, así como interesantes propiedades farmacológicas y actividades biológicas. Esta revisión pretende abordar los llamados quitosanos heparanizados, una familia muy interesante de polisacáridos que han demostrado la capacidad de imitar a los sulfatos de heparano y heparina como ligandos de diferentes proteínas, ejerciendo así su actividad biológica que imita la función biológica de estos glicosaminoglicanos.

[EN] Chitosan is a semisynthetic polysaccharide derived from chitin, the second most abundant biopolymer in nature. Among the many properties of chitosan is that it is biodegradable, biocompatible and non-toxic, and also has varied biological activities (analgesic antitumoral, antimicrobial, antiviral, anti-inflammatory, etc.). Functionalization of chitosan is an emerging research area for developing solutions for a wide range of biomedical applications. In particular, the modification of chitosan with sulfate groups has attracted considerable interest, as this modification offers new and attractive physicochemical properties as well as interesting pharmacological properties and biological activities compared to the parent chitosan. This review deals with the so-called heparanized chitosans, a very interesting family of polysaccharides that have shown the ability to mimic heparan and heparin sulfates as ligands for various proteins, thus exerting their biological activity that mimics the function of these glycosaminoglycans.
