The present invention is directed in particular to dipeptide-like compounds derived from functionally substituted amino acids, having fatty acid chains bound thereto through amidification of the amine functional groups of said dipeptide-like compounds, one end portion of which bears an accessory functional side chain spacer, with the other end portion being an acid group either in neutral or charged state. Compounds of the present invention have immunomodulating properties like adjuvants, In addition, compounds of the invention can be grafted on a given antigen in order to modulate or tune the immune response or can be equally grafted on a pharmaceutical carrier to enhance the therapeutic effect or targetting thereof. Accordingly, compounds of the invention find use in human and veterinary medicine both as immunogens and diagnostic tools.

N-delta-L-Homoserinyl-D-ornithinol pseudodipeptides N-acylated with typical Escherichia coli lipid A fatty acid residues and mono-O- or bis-O-phosphorylated have been prepared and their properties investigated. The derivatives carrying two phosphate groups were found to be inducers of NO production. In addition, while they were unable to induce significantly the production of interleukin-6 (IL-6) by human PBMC cells, these compounds behaved also as potent antagonists of LPS-induced IL-6 production in the same human cells system. In conclusion, the molecules described here are the first members of an original class of immunobiologically active lipid A mimics based on an acyclic pseudodipeptide backbone carrying only the essential functionalities of the parent lipid A structure (OM-174). As the products exhibit very low endotoxicity and pyrogenicity, this class of lipid A mimics therefore opens a new generation of immunoadjuvants that possibly could reach clinical applications.
