Rivipansel
Rivipansel is a small-molecule glycomimetic pan-selectin antagonist with inhibitory activity against E-selectin and P-selectin. Rivipansel binds tightly to the lectin domain of E-selectin, and selectively blocks the recognition of CD62L by E-selectin without affecting the binding of PSGL-1 to E-selectin. Rivipansel functionally inhibits the adhesion of hematopoietic cells to endothelial cells, and is applicable to research related to sickle cell disease.

Biological Activity
Rivipansel dose-dependently inhibits HL-60 cell adhesion to E-selectin-expressing CHO cells in an in vitro shear flow assay, with greater activity against E-selectin than P-selectin[1].
Rivipansel (~6.5 μM) inhibits rolling of isolated human polymorphonuclear neutrophils (PMN) on a recombinant human E-selectin/ICAM-1 coated substrate with a IC50 of ~6.5 μM, via a mechanism independent of PSGL-1[2].
Rivipansel (6.5 μM) reduces E-selectin recognition of sialyl LewisX (sLex) on CD62L in isolated human polymorphonuclear neutrophil (PMN) lysates by ~70%[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Rivipansel (20 mg/kg; i.v.; single dose) rapidly restores cerebral tissue perfusion and reduces cerebral platelet microthrombi in TNFα-induced cerebral occlusion in Townes SCD mice[1].
