Comment: Bimosiamose is a synthetic pan-selectin antagonist [4] being investigated as a novel anti-inflammatory agent, primarily for controlling allergic respiratory diseases [7,9], but it has also been reported to provide benefit in ischemia/reperfusion injury [1-2,5-6,8]. The primary role of selectin inhibitors appears to be disruption of early events in the migration process (possibly mediated through E-selectin [3]), thereby inhibiting their eventual extravasation from blood to the inflammed tissue.
