"Potassium Pyruvate"
 
   The way DCA works is by fixating itself to the Pyruvate Dehydrogenase Kinase and blocking it's ability to regulate the Pyruvate Dehydrogenase Complex.

The COO- Acetate radical ion is the active part of the DCA. The chlorocarbon part, CCl2 is inert and cannot react with other chemicals in the cells. This definitely blocks the Kinase.

What is needed is a small molecule with a COOH part and an inert part but which is not toxic.

The toxicity of DCA comes from the chlorocarbon which breaks down and deionizes sodium channels in the neurons, causing neuropathy.

Also, metabolites of DCA causes Trichloroethylene and other sybstances which are themselves carcinogens, which are especially toxic for the liver because they accumulate there.

I propose that instead of using DCA, we could simply use Potassium Pyruvate.

Pyruvate has one double bonded oxygen and one methyl radical attached to the first carbon. Those two components are more reactive than chlorine but are still quite inert, enough for it to have an effect on the Kinase without the toxic effects of chlorocarbons.

The only toxicity coming from Potassium Pyruvate or Calcium Pyruvate would come from the Potassium and the Calcium itself. You cannot take too much of that without causing kidney, stomach and blood pressure problems.

So I propose to use Potassium Pyruvate instead of Potassium Dichloroacetate.

The effects will be the same but the toxicity will no longer be there.

   Is this Potassium Pyruvate available? Are there any clinical trials?

   Since Randy (parachute) faces problems posting directly in this forum, asked me to post the following article.
==================================================

Of interest, a University of Southern California article, dated 2009.

"Opportunities in discovery and delivery of anticancer drugs targeting mitochondria and cancer cell metabolism."

Abstract:

"Cancer cells are characterized by self-sufficiency in the absence of growth signals, their ability to evade apoptosis, resistance to
anti-growth signals, sustained angiogenesis, uncontrolled proliferation, and invasion and metastasis. Alterations in cellular bioenergetics are an emerging hallmark of cancer. The mitochondrion is the major organelle implicated in the cellular bioenergetic and biosynthetic changes accompanying cancer.
These bioenergetic modifications contribute to the invasive, metastatic and adaptive properties typical in most tumors. Moreover, mitochondrial DNA mutations complement the bioenergetic changes in cancer. Several cancer management therapies have been proposed that target tumor cell metabolism and mitochondria. Glycolytic inhibitors serve as a classical example of cancer metabolism targeting agents.
Several TCA cycle and OXPHOS inhibitors are being tested for their anticancer potential. Moreover, agents targeting the PDC/PDK (pyruvate dehydrogenase complex/pyruvate dehydrogenase kinase) interaction are being studied for reversal of Warburg effect. Targeting of the apoptotic regulatory machinery of mitochondria is another potential anticancer field in need of exploration. Additionally, oxidative phosphorylation uncouplers, potassium channel modulators, and mitochondrial redox are under investigation for their anticancer potential. To this end there is an increased demand for agents that specifically hit their target.
Delocalized lipophilic cations have shown tremendous potential in delivering anticancer agents selectively to tumor cells. This review provides an overview of the potential anticancer agents that act by targeting cancer cell metabolism and mitochondria, and also brings us face to face with the emerging opportunities in cancer therapy."
