Keto Acids

The oxidation of leucine-1-14C to14CO2by Ehrlich ascites carcinoma cells was inhibited on addition of pyruvate and other α-keto acids, a maximum inhibitory effect being attained with 1 mM pyruvate. The only compound, among those tested, which reversed this inhibition was malonate. Oxidation of leucine-2-14C to14CO2occurred at a rate which was 1% of that observed with leucine-1-14C and was sensitive to the presence of fatty acids as well as to pyruvate. Glutamine was a particularly effective inhibitor of leucine oxidation. The inhibition produced by isoleucine was competitive, the KIvalue being 0.13 mM compared with the KMvalue of 0.2 mM. It is suggested that the inhibition by pyruvate is due to a competition between pyruvate and the α-ketoisovaleric acid derived from leucine for the cofactors required for the oxidation of the α-keto acids. In contrast, oxidation of leucine-1-14C by mouse liver slices was increased approximately threefold by pyruvate.

The perchloro-soluble mucroptotein fraction was determined in the cells of Ehrlich ascites carcinoma on the 10th and 12th days post-inoculation of the tumor. After 3 days of a single subcutaneous dose of cyclophosphamide (200 mg/kg) the mucoprotein levels were found considerable lower. This difference was highly significant statistically.

Oxidation Of Glucose

Studies have been made of the effects of metabolic inhibitors on the oxidation and incorporation of radioactivity into nucleotides of glucose labelled in the 1, 2, and 6 positions. The results indicate that in Ehrlich ascites carcinoma cells the predominant oxidative pathway is the hexosemonophosphate shunt. Investigation of the time courses of oxidation of the labelled glucose molecules confirms this conclusion. The pattern of incorporation of radioactivity initially suggests that nucleotide ribose is not formed via this pathway. However, it is shown that the coupling of an active transketolase system with the other enzymes of the hexosemonophosphate shunt provides a sufficient explanation of all the experimental observations. The conclusion is reached that pentose is formed by oxidation of glucose through the shunt but that the labelling pattern is largely established as the result of the exchange reaction catalyzed by transketolase.
