U-104 (SLC-0111) is a potent exosome inhibitor[3].
U-104 has low inhibition for CA I (Ki=5080 nM) and CA II (Ki=9640 nM)[1].
U-104 (50 μM; for 72 hours) blocks the mesenchymal phenotype in the cancer stem cells population in hypoxia condition of 4T1 cells. U-104 (<50 μM) significantly reduces migration in a dose-dependent manner in metastatic MDA-MB-231 LM2-4Luc+ cells , with cells growing as compact colonies similar to parental MDA-MB-231 cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
U-104 (38 mg/kg; i.p.; from 11 to 27 days) significantly delays primary tumor growth and reduces cancer stem cell population in NOD/SCID mice orthotopically implanted with MDA-MB-231 LM2-4Luc+ cells[2].
U-104 (50 mg/kg; oral gavage; continuously for 4 days and suspended for 1 day; from 10 to 30 days) shows a significant delay in tumor growth in Balb/c mice orthotopically implanted with 4T1 cells[2].

Hs578T cells cultured in HCO3−/CO2-buffered medium were treated for 24 h with the NBCn1 inhibitor S0859 (10 µM), the CA IX/XII inhibitor U-104 (10 µM) or a combination of the two compounds added directly in the incubator. Cycloheximide was added the last 30 min and the expression of ERK3 was analyzed by western blotting.
