The present invention relates to compositions and methods for inhibiting the interaction of a ligand and receptor, In particular, compositions are methods are provided for inhibition of interaction between a virus, especially HIV, and a receptor. Inhibition of such ligand/receptor interaction is advantageous in inhibiting infection of a cell with a virus. Further, an inhibitor of ligand/receptor interaction serves as a standard in assays of inhibition in vitro or in vivo. In a particular embodiment, a composition according to the invention includes a compound having the formula: [(X) - (Y)] p - Z where X is (Formula 1) and where Q1 and Q2 are each independently H, a bond to Y, or a bond to Z, where at least one of Q1 or Q2 is a bond to Y or a bond to Z; where R1, R4, R6 and R8 are each H; R2, R3, and R5 are each independently OH, OS03D, or OP03D, and R7 is CH20H, CH20SO3D or CH20PO3D; where D is H or a cation selected from the group consisting of: alkali metal cations, alkaline earth metal cations, ammonium cations, quaternary ammonium cations and amine cations; and where at least one of R2, R3, R5 and R7 is a sulfur or phosphate containing group; where Y is an optional linker, Z is a multivalent support, and p is an integer in the range of 1-2000 inclusive,
