Claim:
A compound having 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, 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, M where M is any pharmaceutically acceptable cation, an alkyl, or an aryl group; 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, or a substituted tetrazole or, or a substituted aryl or derivative, or a substituted heteroaryl or; with the provisos that: at least one of UR 1 or UR is not OSO 3 M, NSO 3 M, OH or OPO 3 M 2 , and at least 50% of the R groups are SO 3 M.
