Abstract

Triterpenoid acid derivatives are described that exhibit dual pharmacophobic activities, specifically selectin ligand and leukotriene biosynthetic inhibitory activities, and that thus have significant applications for the treatment or prevention of certain diseases including cancer and diseases associated with the inflammatory process as well as applications for the diagnosis of disease.
