Abstract

La presente invención se refiere a conjugados del chitosan (o sus derivados) con tiolactonas (síntesis y estructuras químicas), en las composiciones cosméticas, biomédicas-farmacéuticas que contienen dichos conjugados, y a sus aplicaciones, que presentan las siguientes propiedades: no tóxicos, biodegradables, con excelentes propiedades de mucoadhesión, cohesión e inhibición enzimática, con propiedades mejoradas de permeabilidad, captación celular y gran estabilidad como agentes de recubrimiento de cánulas y otros dispositivos médicos y como sistemas transportadores de fármacos, esto es, con largos tiempos de permanencia de los principios activos englobados, lo que garantiza un excelente control en la liberación de los fármacos incluidos en la formulación y además, capaces de gelificar en presencia de oxígeno.
