Abstract

A pH-responsive and targeted polysaccharide conjugate was fabricated from the boronate linkage of N-(2-aminoethyl)-gluconamide-grafted hyaluronic acid with anticancer drug bortezomib, which could exhibit targeted drug release behaviors at acidic pH and possess lower cytotoxicity and a higher inhibition effect toward cancer cells.
