Abstract:
Bioenergetic therapy targeting mitochondrial bioenergy is a promising therapeutic strategy for cancer. However, its clinical efficacy is limited by the metabolic adaptability of tumor cells, as they can switch between glycolytic and oxidative phosphorylation metabolic phenotypes to maintain energy homeostasis. In this study, we discovered 1,8-naphthyridine-piperazine-dithiocarbamate ruthenium(II) polypyridyl complexes (RuL1) that enhanced energy deprivation by inhibiting the activity of mitochondrial complex I and III, thereby disrupting oxidative phosphorylation. Simultaneously, RuL1 inhibits glycolysis while unexpectedly activating antitumor immunity. This dual metabolic-immunological targeting resulted in enhanced anticancer activity against MGC-803 cells. To the best of our knowledge, RuL1 is the first ruthenium polypyridyl complex reported to achieve high anticancer activity through dual metabolic inhibition.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
