A set of heterocyclic ligands have been synthesised for use in the preparation of mixed mode affinity chromatographic adsorbents for application in the purification of proteins, including antibodies. The ligand structures were designed to consist of a pyridinyl or related aza-heterocyclic nucleus bearing a pendant arm containing either an alkylamine, alkylthiol or hydroxyalkyl nucleophilic group to allow their facile immobilisation onto an activated support matrix. Ligand diversity was achieved by altering the length of the alkyl chain between the heterocyclic nucleus and nucleophilic group, varying the position of alkyl chain attachment to the heterocycle, and incorporating extra substituents into the pyridinyl or related aza-heterocyclic ring. This diversity in ligand structure was intended to enable key structural features of the ligand, required for efficient protein binding, to be determined. In contrast to the previously used multi-step procedures for the preparation of analogous substituted pyridine or aza-heterocyclic compounds, the synthesis routes for the ligands described here have generally utilized very mild, one-step reactions with readily available heterocyclic precursors.
