A potent antagonist of the Sonic Hedgehog (Shh) signaling pathway (IC₅₀ = 20 nM in Shh-LIGHT2 assay and in Ptch1^-l-< cells) that acts by binding to Smoothened (Smo; K_D = 1.2 nM), a distant relative of G protein-coupled receptors. In contrast to cyclopamine, SANT-1 inhibits the activities of both wild type and oncogenic Smo with equal potency (IC₅₀ = 30 nM in SmoA1-LIGHT2 assay).

A potent, cell-permeable antagonist of the Shh (Sonic Hedgehog) signaling pathway (IC₅₀ = 20 nM in the Shh-LIGHT2 assay and in Ptch1^-l- cells) by binding directly to Smoothened (Smo; K_d = 1.2 nM), a distant relative of G protein-coupled receptors. Unlike cyclopamine (Cat. No. 239803), SANT-1 equipotently inhibits the activities of both wild-type and oncogenic Smo (IC₅₀ = 30 nM in SmoA1-LIGHT2 assay).

Cell permeable: yes
