U-104 is an inhibitor of CA IX that binds only to CA IX under hypoxic conditions in vivo. The binding results in significant inhibition of tumor growth and metastasis formation in both spontaneous and experimental models of metastasis. U-104 reduces the medium acidity by inhibiting the catalytic activity of the CA IX. It binds specifically only to hypoxic cells expressing CA IX.

Sample Use Guides

In Vivo Use Guide

4T1 cells were implanted orthotopically into Balb/c mice and treatment was initiated after tumors were established.U-104 was solubilized in 55.6% PEG 400, 11.1% ethanol and 33% water at 5 mg/ml, and then administered as oral gavage. In separate experiment MDA-MB-231 LM2-4Lucю cells were implanted into NOD/SCID mice, tumors were established and treatment was initiated. Paclitaxel was administered by i.v. injection and U-104 was provided by intraperitoneal (i.p.) injection according to the dosing schedule.

Route of Administration: Other

In Vitro Use Guide

Parental 4T1 cells were cultured as TSs in hypoxia and subjected to FACS. Viable CD44юCD24_/low or CD44_CD24ю cells were collected. Collected cells were cultured in hypoxia with DMSO or 50 mkM U-104 for 72 h. Cells were fixed and immunostained
