coenzyme Q10 A naturally occurring benzoquinone important in electron transport in mitochondrial membranes. Coenzyme-Q functions as an endogenous antioxidant; deficiencies of this enzyme have been observed in patients with many different types of cancer and limited studies have suggested that coenzyme-Q may induce tumor regression in patients with breast cancer. This agent may have immunostimulatory effects. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
