Chemical structure
| Cell experiment [1]: | |
Cell lines | primary CD34+ CP-CML cells |
Preparation method | The solubility of this compound in DMSO is > 27.85 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reacting condition | 10 nM, 100 nM, 72 hours |
Applications | LDE225 (10 nM, 100 nM, 72 hours) inhibited downstream Hh signaling in primary CD34+ CP-CML cells. LDE225 (0.5-100 nM, 72h) significantly reduced colony forming cell (CFC) re-plating efficiency of primitive human CP-CML cells. LDE225 (10 nM) alone or in combination with nilotinib (5 μM) significantly reduced LTC-IC numbers in primary CD34+ CP-CML samples. |
| Animal experiment [1]: | |
Animal models | CP-CML murine model, BCR-ABL expressing mice |
Dosage form | 80 mg/kg by gavage, daily |
Application | Treatment of Scl-tTa-BCR-ABL mice with LDE225+nilotinib resulted in inhibition of Gli1 in CP-CML BM LTHSC. LDE225 in combination with nilotinib on human CML LSC was capable of engrafting immunodeficient mice. LDE225+nilotinib administration significantly reduced leukaemia stem and progenitor cells in the spleen of BCR-ABL expressing mice. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

IC50: 1.3 and 2.5 nM for Mouse and Human Smo
LDE225 is a potent and selective smoothened antagonist. Smoothened (Smo) is a 7-pass transmembrane protein functioning as the key activator of the hedgehog (Hh) signaling pathway. Hh signaling is tightly controlled during cellular differentiation, proliferation, and embryonic morphogenesis. Hh signaling has been linked to tumorigenesis in several cancers.
In vitro: LDE225 was found to selectively bind to the Hedgehog (Hh)-ligand cell surface receptor Smo, which might result in the suppression of the Hh signaling pathway and, therefore, the inhibition of tumor cells in which this pathway was abnormally activated [1].
In vivo: In the subcutaneous medulloblastoma allograft mouse model, LDE225 demonstrated dose-related antitumor activity after 10 days of oral administration of a suspension. At a dose of 5 mg/kg/ day qd, LDE225 inhibited tumor growth significantly, corresponding to a T/C value of 33%. When dosed at 10 and 20 mg/kg/day qd, LDE225 afforded 51 and 83% regression, respectively [1].
Clinical trial: In a phase I study, it was found that LDE225 had an acceptable safety profile in patients with advanced solid tumors and exhibited antitumor activity in advanced BCC and relapsed medulloblastoma, both of which were associated with hedgehog pathway strongly, as shown by gene expression [2].
