Purity: ≥98%
Crenigacestat (formerly also known as LY3039478) is a novel, potent and orally bioavailable small molecule Notch inhibitor with an IC50 of ~1nM in cell based assays. Also an inhibitor of γ-secretase. LY3039478 potently inhibits mutant Notch receptor activity. In a xenograft tumor model, LY3039478 inhibited N1ICD cleavage and expression of Notch-regulated genes in the tumor microenvironment. LY3039478 is being investigated in Phase I trial.
| ln Vitro |
K07074 cells, a primary mouse liver tumor cell line, show anticancer activity in response to crenigacestat (100 nM) [2]. In mouse and human model systems, crenigacestat (LY3039478) lowers the expression of Myc and cyclin A1, two components of the NOTCH-driven proliferation signature. In CCRCC cells, treatment with crenigacestat (LY3039478) similarly results in G0/G1 cell cycle arrest [3]. Assay for cell viability [2].

|---|---|
| ln Vivo |
The in vivo efficacy of CCRCC was demonstrated by the significant improvement in survival and delay in tumor growth in an independent cohort of mice given oral Crenigacestat (8 mg/kg) three times a week [3].

| Cell Assay |
Cell viability assay [2].
Cell Types: K07074 cells. Tested Concentrations: 100 nM. Incubation Duration: 24-96 hrs (hours). Experimental Results: Effectively inhibited the growth of K07074 cells. |
| Animal Protocol |
Animal/Disease Models: CCRCC xenografts were established using 769-P cell line subcutaneously (sc) (sc) implanted in NOD-scid IL2R-deficient mice [3].
Doses: 8 mg/kg. Route of Administration: po (oral gavage), 3 times per week. Experimental Results: Overall survival of CCRCC xenografts was improved compared to vehicle controls. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.38 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (5.38 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
