Synthesis of substituted terpyridine ligands for use in protein purification
摘要:
A number of 4,4 ''-disubstituted terpyridines bearing a 4'-thioethanamine linker, and regioisomers thereof, have been synthesised from 4-substituted picolinates. The substituted terpyridines were immobilised onto epoxy-activated Sepharose (TM) FF gel, creating functionalised solid supports for the fractionation of proteins-including antibodies-by mixed mode affinity chromatography. The metal chelating properties of the immobilised ligand render the stationary phase also amenable for use in immobilised metal-ion affinity chromatography (IMAC), and have been demonstrated with the purification of suitably tagged green fluorescent protein (GFP).

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
