Abstract
Fifteen novel biphenyl-N-heterocyclic carbene (NHC)-gold(I) complexes were designed and synthesized to treat ovarian cancer (OC). Among these, complex Au-1 showed significant antiproliferative activity against A2780 cells and A2780/CDDP cells. Notably, Au-1 exhibited low toxicity to normal ovarian epithelial IOSE-80 cells. Further studies revealed that Au-1 strongly inhibited thioredoxin reductase (TrxR) activity. Collectively, our results demonstrated that Au-1 could be a promising candidate for the treatment of OC.
