Background:

CITCO, an imidazothiazole derivative, is a selective Constitutive androstane receptor (CAR) agonist. CITCO inhibits growth and expansion of brain tumour stem cells (BTSCs) and has an EC50 of 49?nM over pregnane X receptor (PXR), and no activity on other nuclear receptors[1].

CITCO (1-50 μM; 48?hours) results in a dose-dependent inhibition of viable cell count and proliferation in both T98G and U87MG glioma and BTSCs[1]. CITCO (2.5, 5?μM; 48?hours) induces cell cycle arrest differentially in different BTSCs in culture, but not in normal astrocytes[1]. CITCO (2.5-10?μM; 48?hours) induces apoptosis in BTSCs in culture in dose dependently, but not in normal astrocytes[1]. CITCO (0-25?μM; 48?hours) causes the T98G and U87MG glioma and BTSCs expressing very low levels of CAR protein that increased significantly[1].

CITCO (intraperitoneal; on days 22, 24, 26, 30 and 36) with 25?μg results a significant decrease in tumour growth, which further decreases to an undetectable level after treatment with 100?μg CITCO [1].
