Descripción

General description

A cell-permeable, orally available triazole-class antifungal agent that, in addition to its known inhibitory activity against fungal cytochrome P450 14-α-demethylase, also acts as an effective Hh signaling inhibitor (IC₅₀ ~ 0.8 µM against SHHN-induced Gli transcription activity in Shh-Light2 cells) in a Ptch-independent manner (IC₅₀ ~ 0.9 µM against Ptch promoter-mediated transcription activity in murine Ptch^-/- fibroblasts), presumably by binding smoothened (smo) at a site distinct from that targeted by cyclopamine (Cat. No. 239803) and SAG (Cat. No. 566660), as Itraconazole does not compete with BODIPY-cyclopamine binding, and it alters only the magnitude, but not the EC₅₀, of SAG-induced Gli transcription activity in Shh-Light2 cells. Shown to effectively suppress Hh pathway-dependent growth of both engrafted medulloblastoma and endogenous basal cell carcinoma in mice in vivo (37.5 to 100 mg/kg/12 hr, p.o.) in a reversible manner.
