    • The invention relates to the use of sialic carbohydrates of general formula (I), containing at least one carbohydrate unit of general formula (II) for the immune modulation, immune suppression and in the prevention and treatment of infections in humans and animals. In said formula (II), Sia represents a sialic acid or a sialic acid derivative in an α2-3 bond, Gal represents a galactose-monosaccharide-unit, HexNac represents an N-acetylated galactosamine or glucosamine-monosaccharide-unit (GalNAc or GlcNAc), Hex represents a galactose- or glucose-monosaccharide-unit (Gal or Glc), C represents HexNac or Hex or is absent, n represents 1-50, V represents OH, a carbohydrate radical or a connecting point on a support T, with the proviso that if V represents OH, n represents 1, and if V represents a carbohydrate radical or a support T, n represents the number of carbohydrate unites of general formula (II) directly connected to said carbohydrate radical or support, X represents a sialic acid or a sialic acid derivative, wherein a second sialic acid or a sialic acid derivative or more sialic acid or sialic acid derivatives can be connected to an α2-8 bond, a phosphate, a sulphate, or carboxyl-group or a monosaccharide having a phosphate, sulphate, or carboxyl group and only one of the radicals X is present.
    • 本发明涉及含有至少一种通式(II)的碳水化合物单元的通式(I)的唾液酸碳水化合物用于免疫调节,免疫抑制和预防和治疗人和动物感染的用途。 在所述式(II)中,Sia表示α2-3键中的唾液酸或唾液酸衍生物,Gal表示半乳糖 - 单糖单元,HexNac表示N-乙酰化的半乳糖胺或葡糖胺单糖单元(GalNAc或GlcNAc ),Hex表示半乳糖或葡萄糖单糖单元(Gal或Glc),C表示HexNac或Hex或不存在,n表示1-50,V表示OH,碳水化合物基团或载体T上的连接点, 条件是如果V表示OH,n表示1,并且如果V表示碳水化合物基团或载体T,则n表示与所述碳水化合物基团或载体直接连接的通式(II)的碳水化合物单元的数目,X表示 唾液酸或唾液酸衍生物,其中第二唾液酸或唾液酸衍生物或更多的唾液酸或唾液酸衍生物可以连接到α2-8键,磷酸盐,硫酸盐或羧基或单糖上,其具有 磷酸盐,硫酸盐, 或羧基,并且仅存在基团X中的一个。
