CITCO, an imidazothiazole derivative, is a selective agonist of human CAR, with an EC50 value of 49 nM and > 50-fold selectivity to CAR over pregnane X receptor (PXR), and no activity on other nuclear receptors. Upon activation with specific agonists, CAR translocates into the nucleus and binds to the response elements as monomers or CAR/RXR heterodimers. The CAR functions as a xenobiotic receptor, involved in detoxification and clearance of toxic substances from the liver. In addition, activation with selective CAR agonists such as CITCO has also been shown to inhibit growth and expansion of brain tumor stem cells.

Cell lines
T98G, U87MG, DB29 and DB33 glioma cells
Reaction Conditions
2.5 ~ 10 μM CITCO for 48 h incubation
Applications
The brain tumor stem cells (BTSCs) from T98G and U87MG cultured in the absence of CITCO showed 6.8 and 11% Annexin V-positive cells that increased to 62 and 68% following addition of 10 μM CITCO, respectively. Moreover, BTSCs from DB29 and DB33 gliomas showed 3 and 0.5% Annexin V-positive cells that increased to 24 and 41% following treatment with 10 μM CITCO, respectively. CITCO dose-dependently induced apoptosis in BTSCs in culture, but not in normal astrocytes.
Animal models
Nude mice subcutaneously injected with U87MG–BTSCs
Dosage form
25 or 100 μg
Intraperitoneal injection; on days 22, 24, 26, 30 and 36
CITCO at the dose of 25 μg resulted in a significant decrease in tumour growth, which further decreased to an undetectable level after treatment with 100 μg CITCO.
