TY - JOUR Y1 - 2006/// N2 - The majority of magnetic resonance contrast agents are restricted to the extracellular domains. For the development of novel, intracellular magnetic resonance contrast agents, we have designed Gd-DOTA derivatives comprising PreS2-TML peptide or ethylguanidinium as carrier moiety. Initial in vitro cell uptake studies with Jurkat cells revealed efficient contrast agent uptake for imaging purposes, in the range of 0.04 fmol/cell (PreS2-TML peptide) to 0.2 fmol/cell (ethylguanidinium) following 2 h incubations at 100 µM.
