Abstract
[GRAPHICS] Water and acid resistant arylplatinum(ll) complexes have been covalently bo nded to the N-terminus of L-valine, thus providing organometallic biomolecu les with excellent stability properties. Owing to the Pt-195 nucleus (I = 1 /2), these building blocks are potentially versatile biomarkers (e.g., MRI) , Moreover, they display efficient in vitro biosensor characteristics since they detect SO2 gas selectively and fully reversibly by an instantaneous c hange of the spectroscopic properties including a diagnostic Pt-195 NMR sig nal.
