The invention relates to anionic conjugates of glycosylated bacterial metabolites that may be used to mimic the structure and/or activity of the anionic bioactive molecules known as glycosaminoglycans (GAGs). The invention also relates to processes for the preparation of the conjugates. Such conjugates are useful in the prophylaxis and/or treatment of disease conditions and in particular chronic disease conditions such as inflammatory (including allergic) diseases, metastatic cancers and infection by pathogenic agents including bacteria, viruses or parasites.

Methods and compositions are disclosed that are useful for the prevention and/or treatment of cardiovascular and cardiac diseases and disorders, or damage resulting from surgical or medical procedures that may cuase ischemic or ischemic/reperfusion damage in humans; and cardiovascular trauma. The beneficial effects of the compositions and methods are achieved through the use of pharmaceutical compositions that include agents that interfere with the production and/or biological activities of sphingolipids and their metabolites, particularly sphingosine (SPH) and sphingosine-1-phosphate (S-1-P). Also disclosed are methods for identifying and isolating therapeutic agents.
