Title: Compsns for promoting protein synthesis and nitrogen conservation
Inventor: WALSER MACKENZIE
IPC: A61K31/19
Filed: 1975-04-12
Abstract: Compsns. for promoting protein synthesis and conserving nitrogen in an organism comprise (a) the alpha-hydroxy acid analogues of essential amino acids, (b) the alpha-keto acid analogues of essential amino acids, and opt. (c) essential amino acids themselves. The compsns. can be used to treat renal and hepatic disorders (e.g. uraemia, hyperammoniaemia and portal-systemic encephalopathy) and nutritional protein deficiency. The hydroxy and keto acids modify the basic m tabolic mechanisms: in the case of renal disorders, they promote amino acid synthesis while suppressing the accumulation of urea in the blood stream; in the case of hepatic disorders, they utilise the ammonia in the blood stream for protein synthesis, which corrects nutritional problems while reducing the toxic effects of the ammonia; in the case of protein deficiency, they reduce the amt. of protein reqd. by the organism by suppressing the excretion of nitrogen (e.g. as urea).
