Smoothened

Purmorphamine is a 2,6,9-trisubstituted purine that promotes the differentiation of both human and mouse mesenchymal progenitor cells into osteoblasts.

LDE225 is an orally bioavailable small-molecule Smoothened (Smo) antagonist with potential antineoplastic activity.

PF-5274857 is a novel Smo antagonist that specifically binds to Smo with a K(i) of 4.6 ?? 1.1 nmol/L and completely blocks the transcriptional activity of the downstream gene Gli1 with an IC(50) of 2.7 ?? 1.4 nmol/L in cells.

BMS-833923 (or XL-139) is an orally bioavailable small-molecule SMO (Smoothened) inhibitor with potential antineoplastic activity.

SAG is a chlorobenzothiophene-containing compound which acts as a SMO agonist (EC50 = 3 nM) but inhibits hedgehog signaling at high concentrations (>1 uM).

PF-04449913 is a potent and orally bioavailable inhibitor of smoothened.

Jervine is a naturally occuring steroidal alkaloid that causes cyclopia by blocking sonic hedgehog(Shh) signaling; Jervine is an inhibitor of Smo.
