Abstract
Thioamides, thioureas, and thiocarbamates are introduced as stable, sulfur-based metal-binding pharmacophores (MBPs) for use in metalloenzyme fragment-based drug discovery (mFBDD). MBP reactivity, bioactivity, and structural studies show that these molecules can act as ligands for Zn(II)-dependent metalloenzymes including human carbonic anhydrase II (hCAII) and matrix metalloproteinase-2 (MMP-2).
