Claim:
A compound of the general formula: X—[Y] n —Z—UR 1 wherein: X, Y and Z are each the same monosaccharide unit with a group UR bonded via a single or multiple bond to each non-linking carbon of X, Y and Z, except carbon-1 of monosaccharide Z which bears UR 1 bonded via a single or multiple bond; n is an integer having a value of 0-6; each U is independently C, N, S O CO, COO, NO, NO 2 , S(O), or S(O)O; each R is independently SO 3 M or H, where M is any pharmaceutically acceptable cation, or is any alkyl, aryl, acyl, aroyl, alkyl sulfonyl, aryl sulfonyl, PEG, an alkoxy PEG, H or the group where independently in each AB group, A is O or NH, and B is H, or M where M is any pharmaceutically acceptable cation, an alkyl, an aryl group, or R together with U is N 3 ; and R 1 is SO 3 M, H, aryl, acyl, aroyl, alkyl sulfonyl, aryl sulfonyl, PEG or an alkoxy PEG, or R 1 together with U is N 3 or a substituted triazole, or a substituted tetrazole, or a substituted aryl, or a substituted heteroaryl; with the provisos that: at least one UR is N 3 ; and at least 50% of the R groups are SO 3 M.
