- Mechanism of action
PI-88 retards the growth of primary tumours by inhibiting new blood vessel growth (angiogenesis) in two ways: Heparan sulfate mimicry causes inhibition of heparanase, which prevents the release of angiogenic growth factors from the extracellular matrix (ECM). Interaction with angiogenic growth factors VEGF (Vascular Endothelial Growth Factor), FGF-1 (Fibroblast Growth Factor -1) and FGF-2, reduces their functional activity. PI-88 binds with high (nanomolar) affinity to these growth factors.
