The present invention relates to modulators of the interaction between Epstein-Barr Virus induced receptor-2 (EBI2) and cholest-5-ene-3b,7b,25-triol(7, 25- dihydroxycholesterol)(''7,25DHC'') and/orcholest-5-ene-3b, 7b-diol(7- hydroxycholesterol)(''7HC'') 25-diol (25-hydroxycholesterol)(''25HC''), especially the cholest-5-ene-3b,7a,25-triol(7a, 25-dihydroxycholesterol)(''7a,25DHC'')and/or cholest-5-ene-3b,7b,25-triol(7b, 25-dihydroxycholesterol)(''7b,25DHC'') stereoisomers. The modulator maybe a small chemical molecule, antibody or other therapeutic protein. Methods of medical treatment and methods of identifying modulators are also described.

Two dimeric steroidal terephthalates derivedfrom epimeric 4,5-seco-cholest-3-yn-5-ols were prepared starting from cholesterol in a five-step synthetic sequence. X-ray crystallography shows that the obtained compounds display novel supramolecular networks in the solid state in which the facial hydrophobicity of the steroidal skeletons plays an important role. Unambiguous NMR characterization of the
