Design, synthesis, and screening of biomimetic ligands for affinity chromatography.

Affinity chromatography is ideally suited to the purification of pharmaceutical proteins due to its unique bio-specificity characteristics. Tailor-made affinity ligands that represent a promising class of synthetic affinity ligands have been developed to target specific proteins and designed to mimic peptidal templates, natural biological recognition motifs, or complementary surface-exposed residues. These biomimetic ligands have been generated by a combination of rational design, combinatorial library synthesis, and subsequent screening of potential leads against target proteins. Small ligands based on a triazine scaffold also present exceptional selectivity and stability, which allows their use in harsh manufacturing environments.
