Coordinate-bond-dependent solid-phase organic synthesis of biotinylated desferrioxamine B: a new route for metal-specific probes?

Abstract

Desferrioxamine B (DFOB) was biotinylated at the pendant amine using solid-phase organic synthesis (SPOS) on a matrix used conventionally for metal affinity chromatography. The strength of the DFOB-matrix coordinate bonds was functionally equivalent to a covalent bond which underpinned the veracity of the SPOS format. After washing excess reagents, biotin-DFOB was eluted from the matrix with water at pH 6.
