Abstract

Triterpenoid acid derivatives have been found to have structures similar to natural ligands to the extent that these derivatives bind to natural selectin receptors including endothelial leukocyte adhesion molecule-1 (ELAM-1) and leukocyte/endothelial cell adhesion molecule-1 (LECAM-1). The molecules can be administered to the patients by themselves or in pharmaceutical formulations in order to alleviate inflammation and/or treat other abnormalities associated with the excessive binding of leukocytes to endothelial receptors.
