Description: Patidegip, laos known as Saridegib and IPI-926, is an orally bioavailable, cyclopamine-derived (for structure comparison see Fig 1) inhibitor of the Hedgehog (Hh) pathway with potential antineoplastic activity. Specifically, Hedgehog pathway inhibitor IPI-926 binds to and inhibits the cell membrane-spanning G-protein coupled receptor SMO, which may result in the suppression of Hh pathway signaling and a decrease in tumor cell proliferation and survival. SMO is activated upon binding of Hh ligand to the cell surface receptor Patched (PTCH); inappropriate activation of Hh signaling and uncontrolled cellular proliferation may be associated with SMO mutations.
