Definitions

  • the present invention is in the field of human and animal nutrition and nutritional supplementation and relates to compositions which contain folic acid and 5-methyltetrahydrofolic acid and / or its polyglutamates. It also relates to the use of these compositions.
  • Folic acid (N-pteroyl-L-monoglutamic acid) is a widespread growth factor with a vitamin character. Folic acid itself is not found in plant and animal foods.
  • the forms of folic acid found in nature are reduced folates in the form of polyglutamates.
  • the de novo synthesis of these folates is only possible for microorganisms and plants.
  • the polyglutamates are broken down into monoglutates by the folate conjugase in the brush border lines of the small intestine. Only the monoglutamates can be absorbed through the intestinal mucosa in an active transport process.
  • the biologically inactive folic acid is reduced to 7, 8-dihydrofolic acid using the enzymes folate reductase and to 5, 6, 7, 8-tetrahydrofolic acid (THF) using dihydrofolate reductase.
  • THF is the actually physiologically active form of folic acid: THF is a transport metabolite for one-carbon bodies, their transmission via 5-methyl-tetrahydrofolate, 5, 10-methylene-tetrahydrofolate, 5-formyl-tetrahydrofolate (folinic acid) , 5-formimino ⁇ tetrahydrofolate, 10-formyl tetrahydrofolate or 5, 10-methenyl tetrahydrofolate.
  • the Cl building blocks are for the biosynthesis of purine nucleotides and deoxythymidine 5 'monophosphate, ie as precursors of deoxyribonucleic acids (DNA).
  • Folate deficiency can be caused by a lack of food intake, increased need (e.g. during pregnancy and breastfeeding, alcohol abuse), a lack of absorption from food (e.g. as a result of celiac disease or sprue), by the simultaneous intake of antimetabolites (e.g. methotrexate or aminopterin, which are used in the context of chemotherapy as competitive inhibitors of difolate reductase, or sulfonamides which inhibit folate biosynthesis as antimetabolites of 4-aminobenzoic acid) or by genetically caused dysfunction in one of the enzymes of Echate ice folate, for example methylene tetrahydrofolateductase, is formed.
  • antimetabolites e.g. methotrexate or aminopterin, which are used in the context of chemotherapy as competitive inhibitors of difolate reductase, or sulfonamides which inhibit folate biosynthesis as antimetabolites of 4-aminobenzoic acid
  • NTDs neural tube defects
  • No. 4,753,926 describes foods for infants, especially for premature babies, which contain 40 to 150 ⁇ g folic acid / 100 ml.
  • Clinical studies have shown the effectiveness of folic acid administration in pregnant women to prevent NTDs in newborns.
  • the effect of folic acid to lower the level of homocystem (risk factor for cardiovascular diseases) in the blood is also clinically proven (Hankey et al, 1999, Lancet, 354, 407-413). Intake of at least 400 ⁇ g folic acid / per day is necessary. to have a positive influence on the level of homocystem in the blood.
  • DGE Society for Nutrition
  • folic acid is the oxidized form of the folate in the form of the monoglutamate (N-pteroyl-L-glutamate acid).
  • a folic acid supplementation of 0.2 to 0.5 mg / kg dry weight of feed for poultry and pigs is recommended for animal feed.
  • an increase in folic acid supplementation to 0.5 - 1.0 mg / kg feed for poultry and 0.5 - 2.0 mg feed for pigs is recommended (Association for Active Ingredients in Animal Nutrition eV vitamins in der Tierernahrung, Bonn, 1991).
  • WO 97/27764 proposes the use of the naturally occurring isomers of the reduced folates for the enrichment of foods and food supplements.
  • US Pat. No. 5,624,686 suggests reduced folates for increasing the fat content of breeding pigs.
  • the reduced folates are used in substance or in the form of liver powder or microbial cell disruption.
  • EP 646 322 A1 describes an animal feed additive for pigs which contains reduced folates in the form of 7, 8-dihydrofolic acid, Leucovorm (5-formyltetrahydrofolic acid) and / or microbial cell disruption or cell extracts.
  • WO 99/37155 proposes therapeutic compositions which contain at least 2 substances which are selected from the group consisting of tyrosine, methylating agents, phospholipids, fatty acids and St. John's Word (Hype ⁇ cum perforatum). These preparations are proposed for the prevention and / or treatment of depression and for the regulation of neurotransmitter levels.
  • the object of the present invention was therefore to provide compositions which ensure an adequate supply of folate in humans and animals. These compositions should ensure that the folates are bioavailable to all parts of the population and animals. These compositions should be chemically stable and can be used independently of the formulation in food, animal feed and food supplements for humans and animals. It was of particular interest to provide preparations which, in humans and animals, have a wide variety of disorders in the folate metabolism ( genetic defects or resorption disorders), guarantee an adequate supply of folate. In addition, it would be desirable to obtain compositions which, in terms of their effectiveness (increase folate status in the blood, prevention of folate deficiency symptoms, etc.), have a synergistic effect compared to the compositions of the prior art.
  • the preparations according to the invention are suitable for solving this complex task. It is thus possible to ensure the folate supply for humans and animals (via the folic acid additive) and at the same time to make available the quantities of folates in a harmless form that are necessary for the preventive effects and cannot be achieved through folic acid administration (through the addition of 5-methyltetrahydrofolic acid and / or their polyglutamates). Surprisingly, it was found that the preparations according to the invention synergistically increase the folate status in the Blood plasma can be reached. Furthermore, it has been found that the naturally occurring reduced folates unexpectedly increase the stability of the folic acid.
  • the preparations are suitable for ensuring a reliable (and largely independent of defects in the folate metabolism) supply of folates in humans and animals with a wide variety of disorders in the folate metabolism.

  • 5-methyltetrahydrofolic acid can be prepared synthetically from folic acid by methylation and hydrogenation (as described, for example, in DE 2807393 C2). Since the folic acid contains the (S) -configured glutamic acid, the two diastereomers of tetrahydrofolic acid that are formed have (6S, S) and (6R, S) configurations. The diastereomers can be separated, for example, by fractional crystallization (EP 0 455 013 Al) or using N-ethyl-2-ammomethylpyrroleid (EP 0 612 322 B1).
