GANT61

GANT61 is an inhibitor for GLI1 as well as GLI2-induced transcription, inhibits hedgehog with IC50 of 5 μM, displays selectivity over other pathways, such as TNF and glucocorticoid receptor gene transactivation. GANT61 inhibits the DNA binding ability of GLI1. GANT61 inhibits hedgehog signaling with IC50 of 5 μM, displays selectivity over other pathways, such as TNF signaling/NFκB activation, glucocorticoid receptor gene transactivation, and the Ras–Raf–Mek–Mapk cascade. GANT61 efficiently inhibited in vitro tumor cell proliferation in a GLI-dependent manner. GANT61 induces inhibition of DNA replication in early S-phase in human colon carcinoma cell lines, leading to DNA damage signaling involving an ATM–Chk2 axis and induction of cell death.
