== Publication Abstract from PubMed ==
Double trouble: A hybrid organic-inorganic (organometallic) inhibitor was designed to target glutathione transferases. The metal center is used to direct protein binding, while the organic moiety acts as the active-site inhibitor (see picture). The mechanism of inhibition was studied using a range of biophysical and biochemical methods.

Rational design of an organometallic glutathione transferase inhibitor.,Ang WH, Parker LJ, De Luca A, Juillerat-Jeanneret L, Morton CJ, Lo Bello M, Parker MW, Dyson PJ Angew Chem Int Ed Engl. 2009;48(21):3854-7. PMID:19396894<ref>PMID:19396894</ref>
