19 F-Tagged metal binding pharmacophores for NMR screening of metalloenzymes

Abstract

This study demonstrates the screening of a collection of twelve 19F-tagged metal-binding pharmacophores (MBPs) against the Zn(ii)-dependent metalloenzyme human carbonic anhydrase II (hCAII) by 19F NMR. The isomorphous replacement of Zn(ii) by Co(ii) in hCAII produces enhanced sensitivity and reveals the potential of 19F NMR-based techniques for metalloenzyme ligand discovery.
