Mitochondrial uncoupler MB1-47 is efficacious in treating hepatic metastasis of pancreatic cancer in murine tumor transplantation models

Abstract:

Pancreatic ductal adenocarcinoma (PDA) is aggressive cancer characterized by rapid progression, metastatic recurrence, and highly resistant to treatment. PDA cells exhibit aerobic glycolysis, or the Warburg effect, which reduces the flux of pyruvate into mitochondria. As a result, more glycolytic metabolites are shunted to pathways for the production of building blocks (e.g., ribose) and reducing agents (e.g., NADPH) for biosynthesis that are necessary for cell proliferation. In addition, PDA cells are highly addicted to glutamine for both maintaining biosynthetic pathways and achieving redox balance. Mitochondrial uncoupling facilitates proton influx across the mitochondrial inner membrane without generating ATP, leading to a futile cycle that consumes glucose metabolites and glutamine. We synthesized a new mitochondrial uncoupler MB1-47 and tested its effect on cancer cell metabolism and the anticancer activity …
