Bromopyruvic acid, or bromopyruvate, is a synthetic brominated derivative of pyruvic acid. It is being studied as a potential treatment for certain types of cancer. Initial studies in laboratory animals researchers at Johns Hopkins showed that bromopyruvic acid is effective at eliminating aggressive liver tumors.[1]

According to the Warburg hypothesis, unlike normal tissues, which derive most of their energy in the form of adenosine triphosphate (ATP) by metabolizing either glucose or fatty acids for energy production in the mitochondria, aggressive cancers obtain much of their ATP by metabolizing glucose directly to lactic acid.[2] The mechanism of action of bromopyruvic acid involves interruption of this latter process by the inhibition of the enzyme Glyceraldehyde 3-phosphate-dehydrogenase.[3]

The research group of J.F. Geschwind reported that intra-arterial delivery of bromopyruvic acid directly to the site of a tumor represents a new strategy for stopping the growth of liver cancer while minimizing toxic side-effects.[4]

While pre-clinical studies have been promising, human clinical trials to study the effectiveness of bromopyruvic acid have not yet begun.[citation needed] Application for patent has already been submitted.[5]

The first clinical use of 3-bromopyruvate to treat patients with late stage liver cancer was reported to have taken place in 2010 under a compassionate use proptocol, where a total of two patients received 3-bromopyruvate intraarterially. The patients were treated using a special patented formulation of 3-bromopyruvate invented by Ko, Pederson and Geschwind.
