Abstract
New gold(I) thiolate complexes have been synthesized and characterized, and their physicochemical properties and anticancer activity have been tested. The coordination of PTA derivatives provides optimal hydrophilicity/lipophilicity properties to the complexes, which present high solution stability. Moreover, the complexes show a high anticancer activity against Caco-2 cells, comparable to that of auranofin, and a very low cytotoxic activity against enterocyte-like differentiated cells. Their activity has been shown to produce cell death by apoptosis and arrest of the cell cycle because of interaction with the reductase enzymes and consequent reactive oxygen species production. Some of these new complexes are also able to decrease the necessary dose of 5-fluorouracil, a drug used for the treatment of colon cancer, by a synergistic mechanism.
