Abstract: The present invention relates a novel class of biologically active compounds, to processes for their production and to their use in therapy. More particularly the invention provides immunogenic conjugates useful for generating T cell immunity against tumor-associated carbohydrate structures or against carbohydrate structures expressed on infectious agents and/or infected host cells. The said immunogenic conjugate comprises,(i) a peptide component capable of binding a MHC class I molecule; and (ii) a carbohydrate component having the immunogenic specificity of said carbohydrate structure.

Abstract: The present invention relates to a novel class of immunologically active compounds, to processes for their production and to their use in therapy. In particular, the invention provides immunogenic peptide-carbohydrate conjugates useful for generating T cell immunity against tumor-associated carbohydrate structures, or against carbohydrate structures expressed on infectious agents and/or infected host cells. The immunogenic conjugate comprises a peptide component capable of binding a MHC class I molecule and a carbohydrate component having the same immunogenic characteristics of the carbohydrate structure on the tumor cell, infectious agent or the infected cells.
