Effects of dichloroacetate on brain pyruvate dehydrogenase
Abstract:
The action of dichloroacetate (DCA) on pyruvate dehydrogenase (PDH) activity of rat brain has been studied in vitro and in vivo. In a crude brain mitochondrial fraction, DCA inhibits PDH kinase and in rat brain slices this compound increases PDH activity and stimulates glucose oxidation. In the whole animal, intraperitoneal injection of DCA causes activation of brain PDH, indicating that this inhibitor crosses the blood-brain barrier. The same treatment with DCA also produced a large increase in heart PDH activity. Further studies of the effects of DCA on the CNS should lead to results of considerable importance.

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
