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.

IPI-926 is currently developed by Infinity Pharmaceuticals, Inc. Malignant activation of the Hedgehog pathway is implicated in multiple cancer settings and Infinity's development strategy is designed to enable IPI-926 to target a broad range of critical oncology targets - from the tumor cell to the cancer microenvironment. This broadly applicable, targeted approach represents an innovative method for fighting cancer and has potential in treating a range of cancers, including pancreatic cancer, small cell lung cancer, ovarian cancer, bladder cancer, medulloblastoma, basal cell carcinoma, and certain hematological malignancies.
