We studied the effect of different concentrations of 2-deoxy-d -glucose on the l -[U-14C]leucine, l -[1-14C]leucine and [1-14C]glycine metabolism in slices of cerebral cortex of 10-day-old rats. 2-deoxy-d -glucose since 0.5 mM concentration has inhibited significantly the protein synthesis from l -[U-14C]leucine and from [1-14C]glycine in relation to the medium containing only Krebs Ringer bicarbonate. Potassium 8.0 mM in incubation medium did not stimulate the protein synthesis compared to the medium containing 2.7 mM, and at 50 mM diminishes more than 2.5 times the protein synthesis compared to the other concentration. Only at the concentration of 5.0 mM, 2-deoxy-d -glucose inhibited the CO2 production and lipid synthesis from l -[U-14C] leucine. This compound did not inhibit either CO2 production, or lipid synthesis from [1-14C]glycine. Lactate at 10 mM and glucose 5.0 mM did not revert the inhibitory effect of 2-deoxy-d -glucose on the protein synthesis from l -[U-14C]leucine. 2-deoxy-d -glucose at 2.0 mM did not show any effect either on CO2 production, or on lipid synthesis from l -[U-14C]lactate 10 mM and glucose 5.0 mM.
