<p>The compounds have the general formula I <IMAGE> in which R<1> is a hydrogen atom, an alkyl group with 1 to 5 C atoms, a carboxyl group, a benzyloxycarbonyl group or a -CO- carrier, R<2> is a hydrogen atom, a hydroxyl group, a tertiary alkyloxy group with 4 to 10 C atoms or -O-C(CH3)2-Ph(OCH3)m with m = 0 to 3, R<3> is a hydrogen atom, a carboxyl group, C1-C4-alkyloxycarbonyl or benzyloxycarbonyl group or -CO-A-NH-(CH2)a-CO-T where A is a hyphen or a naturally occurring L-amino acid residue in which, where appropriate, the reactive groups which do not participate in the peptide linkage are protected with protective groups customary in peptide chemistry, and T is a hydroxyl group, an O-alkyl or O-arylalkyl protective group, a carboxyl-activating group, a kephalin residue or carrier, preferably a protein, polypeptide, a gel carrying amino groups or an adsorbent and a is 1 to 10, R<4> is a glycosyl radical which is unprotected or protected with protective groups customary in carbohydrate chemistry and is derived from a glycopyranose, glycofuranose or an oligosaccharide, and n is 0 to 3, and are used, bonded to a carrier, as artificial antigens, glycolipids, inhibitors or immunoadsorbents.</p> |
