Description

Composition for promotion of protein synthesis and suppression of urea formation in the body 42726/2 The invention generally relates to a therapeutic composition of matter. Particularly, the several embodiments of the invention provide compositions for treatment of renal disorders, such as uremia, for treatment of hepatic diseases, such as hyperammonemia and portal-systemic encephalopathy, and for alleviating the effects of dietary protein deprivation. . r or art treatrcaa,.
Protein deprivation due to dietary deficiency is most easily treated by introduction of adequate protein to the diet. In instances, either economic or otherwise, where such a course proves impractical, the present invention may be used to reduce protein requirements by diverting nitrogen precursors in the body away from urea formation (urea is excreted, resulting in bodily protein loss) by combination, of these precursors with keto-acid analogs of essential amino acids to form the amino acids.
SUMMARY OF THE INVENTION The present invention provides a composition of matter and a mot4¾od for promoting protein synthesis and suppressing urea formation in the human body, certain embodiments of the composition of matter and of the method being applicable to medicinal treatment of both renal and hepatic disorders and to treatment of dietary protein deficiencies. The present composition of matter comprises keto-acid analogs of certain essential amino acids. Oral or intravenous administration of these keto-acids acts as a treatment for renal failure by promoting protein synthesis in the blood stream, thereby resulting in suppression of urea breakdown which correspondingly reduces the tendency of the liver to form urea. Contrary to the prior art prediction that a high urea breakdown rate would facilitate the use of keto-acids in the body, the present invention demonstrates that urea breakdown actually impedes the use of keto-acids. The reduction of urea breakdown tends to reduce the net rate of urea-nitrogen appearance in the body, thereby pointing to the use of one embodiment of the present composition of matter to reduce urea breakdown in the body so as to minimize the rate of urea formation by the liver. Thus, renal disorders, such as uremia, may be controlled in certain instances without dialysis or as a supplement thereto.
Treatment of hepatic disorders through the use of the compositions of the present invention also calls for the effective suppression of urea formation in the body due to the combination of nitrogen-containing urea precursors, such as ammonia, with the keto-acid analogs of certain essential amino acids. This process results both in the formation of the essential amino acids via synthesis of the keto-acid analogs thereof with ammonia in normal muscle tissue and in the reduction of ammonia in the blood stream, both being highly desirable objects in the treatment of hepatic disorders. This synthesis in normal muscle tissue as now understood provides a basis for use of the present invention as a treatment for hepatic disorders wherein the liver is incapable of performing such a metabolic function.
The invention is further applied to treatment of dietary protein deficiencies by reducing protein requirements. Conversion of the keto-acid analogs of certain essential amino acids in the body suppresses urea formation by diverting nitrogenous precursors of urea away from urea formation through combination of said precursors with the keto-acids to form amino acids. Urea formed in the body is normally excreted, thereby resulting in a systematic loss of elementary protein components. Reduction of this loss of urea coupled with conversion of said nitrogenous ; urea precursors to avialable amino acids allows bodily conservation of protein without toxic effects.
It is therefore an object of the invention to provide a composition of matter for promoting protein synthesis and suppressing urea formation in the human body.
It 1s another object of the Invention to provide a pharmaceutical composition adapted for medicinal treatment of renal and hepatic disorders and treat ment of dietary protein deficiencies. - 4a -
