Discovery Platform for Therapeutic D-Proteins

Written by Antibody Solutions Research Team | 12/11/16 5:59 PM

Stereochemistry is a fundamental property of proteins that defines their shape and biologic function. Proteins made of L-amino acids have inherent limitations as drugs since they are degraded by proteases which reduce their halflife and are often neutralized by an immune reaction to the protein. Therapeutic proteins made of D-amino acids overcome these limitations since they are inherently resistant to degradation by proteases and have dramatically reduced immunogenicity. Results for VEGF-A and additional therapeutic target proteins are presented


Summary

D-amino acid proteins, with longer half-lives and lower immunogenicity than their L-protein counterparts, can bind with high affinity and block the action of therapeutic target proteins. D-amino acid proteins are a new class of therapeutic protein that can offer unique opportunities for the treatment of disease
