Lith-O-Asp is a sialyltransferase (ST) inhibitor, with IC50 values ranging from 12-37 μM against ST3Gal I, ST3Gal III, and ST6GalI. It inhibits α-2,3- and α-2,6-sialyltransferases, decreasing sialic acid transfer to targeted glycoproteins. Research shows potential in suppressing cancer angiogenesis and metastasis, with treated mice exhibiting fewer lung metastases in a 4T1-Luc breast cancer model.
- Sialyltransferase (ST) inhibitor
- IC50 values of 12-37 μM against ST3Gal I, ST3Gal III, and ST6GalI
- No apparent growth inhibition effect on different cancer cell lines at tested doses (10, 30, and 60 μM)
- Decreases expression of cell surface α-2,3- and α-2,6-sialylated antigens
- Suppresses FAK/paxillin signaling and cancer angiogenesis and metastasis pathways in vivo
