Abstract: Medical and therapeutic value of gold has been recognized thousands of years ago, but its rational use in medicine has not begun until the early 1920s. Cisplatin is one of the first metal-containing compounds with anti-cancer activity discovered in the 1960s. Despite the fact that cisplatin treatment is efficient for several types of solid tumors, its effectiveness is limited by toxic side effects and tumor resistance that often leads to the occurrence of secondary malignancies. Since gold(III) is isoelectronic with platinum(II) and tetracoordinate gold(III) complexes have the same square-planar geometries as cisplatin, the anticancer activity of gold(III) compounds has been investigated. Previous studies suggested that, in contrast to cisplatin, gold complexes target proteins but not DNA. Recently, we have investigated gold(III) dithiocarbamates for their anticancer activity and showed that their primary target is the proteasome. Treatment of human breast tumorbearing nude mice with a gold(III) dithiocarbamate complex resulted in significant inhibition of tumor growth, associated with proteasome inhibition and massive apoptosis induction in vivo. Better understanding of physiological processing of gold compounds will provide a rational basis for their further development into novel anticancer drugs.
