  • Patent number: 5648344
    Abstract: Ligands that bind to human selectin receptors are disclosed. The ligands are formulated with excipient carriers to form compositions which are administered to treated condition such as inflammation. The ligands have the structural formula III ##STR1## or molecules which have hydrogen bond donor groups equivalent to the circled groups with respect to their ability to form hydrogen bonds with a selectin under physiological conditions.

  • Patent number: 5624909
    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.
