Summary
Lith-O-Asp is a sialytransferase (ST) inhibitor, with IC 50 s of 12-37 μM.
IC50 & Target
IC50: 12-37 μM (ST) [1] .
In Vitro
The results indicate that Lith-O-Asp shows no apparent growth inhibition effect toward different cancer cell lines at the tested doses of 10, 30, and 60 μM. By in vitro activity assay, it is revealed that the ability of Lith-O-Asp to inhibit the activities of ST3Gal I, ST3Gal III, and ST6GalI. The IC 50 values ranged from 12 to 37 μM. Flow cytometry shows a significant decrease in the expression of cell surface a-2,3- and a-2,6-sialylated antigens on The results indicates that Lith-O-Asp decreased the activity of both a-2,3- and a-2,6-sialyltransferases, and thus inhibit the transfer of sialic acids to the targeted glycoproteins [1] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
A significant amount of secondary metastatic cancer cells are observed in lung tissues of DMSO control mice detected using IVIS in vivo imaging system after 26 days of fat pad inoculation. However, Lith-O-Asp–treated mice show fewer lung metastases. All DMSO-treated mice confirm secondary lung metastasis, but only 3 of 8 Lith-O-Asp-treated mice show lung metastasis. Average tumor nodules per mouse are 11±9 nodules in DMSO-treated group, and 2±4 nodules in Lith-O-Asp-treated group. Additionally, significantly stronger 4T1-Luc illumination signals are shown in control mice than in those injected with Lith-O-Asp-treated cancer cells on days 7 and 9 [1] .
