SPP-002 is a sulfate analogue that acts as a potential Sialyltransferase (ST) inhibitor. SPP-002 selectively inhibits n-glycosialylation with inhibition at least an order of magnitude greater than that of unmodified parental cholic acid (LCA) . SPP-002 reduces tumor cell migration and invasion by inhibiting the integrin /FAK/Paxillin signaling pathway. SPP-002 can be used in the study of tumor metastasis[1].
