N-ACYL DIPEPTIDES AND THEIR USE

摘要

2.1. Difficulties may arise when certain amino acids are to be provided in dissolved form in solutions for infusion or in nutrient media, since the amino acids are either sparingly soluble or unstable in solution. The latter applies, in particular, to dipeptides. The novel dipeptide derivatives will have to be readily soluble and readily bioavailable and stable under sterilisation conditions. 2.2. The novel N-acyl-dipeptides are those of the formula R<2>-NH-CHR<1>-CO-AS in which AS represents a natural amino acid which is sparingly soluble or unstable in solution, R<1> represents a radical of a natural amino acid, and R<2> represents an acyl radical having 1 to 6 carbon atoms. 2.3. Source of C-terminal amino acids in mixtures or solutions for enteral or parenteral (artificial and dietetic) nutrition or in nutrient media for cell cultures.
