| 其他信息 |
Smoothened Antagonist BMS-833923 is an orally bioavailable small molecule SMO (Smoothened) inhibitor with potential antineoplastic activity. SMO inhibitor BMS-833923 inhibits the sonic hedgehog (SHH) pathway protein SMO, which may result in a suppression of the SHH signaling pathway. SMO is a G-protein coupled receptor that lies just downstream of the SHH ligand cell surface receptor Patched-1 in the SHH pathway; in the absence of ligand Patched-1 inhibits SMO and ligand binding to Patched-1 results in increased levels of SMO. The SHH signaling pathway plays an important role in cellular growth, differentiation and repair; constitutive activation of this pathway is associated with uncontrolled cellular proliferation and has been observed in a variety of cancers.
BMS-833923 (XL-139) is a potent, selective oral small-molecule antagonist of the SMO receptor, inhibiting the Hh signaling pathway [2][3] - Its mechanism of action involves binding to the transmembrane domain of SMO, preventing activation by Hh ligands and blocking downstream Gli transcription factor-mediated proliferation and survival of Hh-dependent cancer cells [2][3] - BMS-833923 (XL-139) exhibits in vitro and in vivo efficacy against Hh pathway-dependent tumors, including basal cell carcinoma and prostate cancer [2][3] - It has been evaluated in preclinical studies for the treatment of locally advanced or metastatic BCC and castration-resistant prostate cancer [1][3] - BMS-833923 (XL-139) is used as a tool compound to study Hh pathway signaling in solid tumors and validate SMO as a therapeutic target [2][3] |
