Three heterobimetallic gold(I)-ruthenium(II) complexes containing heteroditopic bipyridine-N-heterocyclic carbene (NHC) ligands were synthesized and fully characterized by spectroscopic methods and in one case by single-crystal X-ray diffraction. In addition, the in vitro cytotoxic, antileishmanial, and antimalarial activities of these new heterobimetallic complexes were assessed. Moreover, the photophysical properties of two compounds have been used to localize them in tumor cells by confocal microscopy.
Synthesis, structures, and antimalarial activities of some silver(I), gold(I) and gold(III) complexes involving N-heterocyclic carbene ligands
proligands and their corresponding silver(I), gold(I) and gold(III) complexes but also the new here described compounds were investigated in a chloroquine-resistant strain of Plasmodium falciparum, and against two Candida strains, respectively. For the first family, interesting antiplasmodial and antifungal activities were found for the dinuclear silver(I) species but they also showed strong hemolytic
