| abstract |
New compounds of the general formula I are described <IMAGE> in which R¹ and R² each represent a hydrogen atom, an acyl or benzyl protective group, R¹ and R² together an alkylidene or benzylidene protective group, R <4> a hydrogen atom, an acyl or benzyl protecting group or a 2,3,4-tri-O-benzyl-alpha-L-fucopyranosyl or alpha-L-fucopyranosyl residue, R 5 H, OH, NH 2, NHNH 2, N 3, O-alkyl , O-aryl, NH- (CH2) mNH2 with m = 2-5, lysine, polylysine or a carrier, n 1 to 10 and R³ is a hydrogen atom, an acyl or benzyl protective group or an alpha-D-glycopyranosyl radical of the general formula II, <IMAGE> where R <6> is a hydrogen atom or an acyl or benzyl protective group, R <7> is a hydrogen atom or halogen and R <8> is a hydrogen atom, an acylocy or benzyloxy group or a Azido, amino, acetamido or hydroxyl group, and a process for their preparation and their use, bound to a carrier, as artificial antigens, glycolipoids or immunoadsorbents. |
