Synthesis, Characterization, and Biological Activity of Aminated Zymosan.

ABSTRACT: Zymosan (ZM), a naturally occurring insoluble macromolecule obtained from the cell wall of Saccharomyces cerevisiae, is used as a functional food (as dietary fiber), phagocytic stimulus, and immune potentiator. The present study aimed to increase its solubility and evaluate its immunological application. ZM was converted into soluble 6-amino-6-deoxy-β-(1-3)-glucan of a molecular weight of 296 kDa by reduction. Detailed structural characterization of aminated ZM was determined by Fourier transform infrared spectroscopy and two-dimensional NMR analysis (2D, COSY, TOCSY, ROSEY, NOSEY, and HSQC). Aminated ZM was biocompatible with Raw 264.7 macrophage cell lines up to a concentration of 100 μg/mL. Rhodamine tagging revealed that the aminated ZM microparticles were found localized within
