Abstract:International audienceIn vivo molecular imaging involves different techniques to image cellular biochemical processes. Metal complexes can be used as cell-permeable medical imaging agents. In this work we studied the cytotoxicity and the cellular incorporation kinetics of two recently synthesized picolinate macrocyclic complexes, [Eu(do2pa)]+ and [Cu(te1pa)]+. Both complexes are able to enter inside the cells. The intracellular concentration (Ci) of [Eu(do2pa)]+ is ∼5 times the extracellular concentration (Ce)… Show more
