In human T-ALL cell lines, MRK-560 (30, 100, 300, and 1000 nM; 15 days) inhibits mutant NOTCH1 receptor signaling [1].

| ln Vivo |
In the T-ALL model, MRK-560 (15.54 mg/kg; SC; once daily for 14 days) has potent anti-leukemia actions [1]. In a dose-dependent way, MRK-560 (1, 3, 10, 30, 100 mg/kg; oral; single dose) exhibits good blood-brain barrier permeability in rats [2]. The oral single-dose medication MRK-560 (1, 3, 10, 30, 100 mg/kg) reduces the brain's and cerebrospinal fluid's ability to produce Aβ [2]. With a Tmax of 12 hours, MRK-560 (1 mg/kg; oral; single dosage) exhibits high bioavailability of 70 to 90% [2]. A once-daily dosage of MRK-560 (1 mg/kg; IV; single dose) is appropriate due to its low plasma clearance and longer half-life than 15 hours [2].

| Cell Assay |
Cell Proliferation Assay[1]
Cell Types: HPB-ALL, DND-41 and Jurkat Cell Tested Concentrations: 30, 100, 300, 1000 nM Incubation Duration: 15 days Experimental Results: diminished NICD1 production in cells and resulted in dose-dependent reduction of HPB -ALL and DND-41 proliferation, whose survival depends on NOTCH signaling. |
| Animal Protocol |
Animal/Disease Models: Tg(HLA-DRB1)31Dmz/Szj(NSG) mouse (T-ALL (T-cell acute lymphoblastic leukemia) model) [1].
Doses: 15.54 mg/kg Route of Administration: subcutaneous injection; one time/day for 14 days. Experimental Results: A strong antileukemic effect was produced and the median survival of vehicle-treated mice was increased from 18 to 30 days. Animal/Disease Models: Male SD (SD (Sprague-Dawley)) rat (250-300 g) [2]. Doses: 1, 3, 10, 30, 100 mg/kg Route of Administration: Oral; single dose (experiment conducted after 8 hrs (hrs (hours))) Experimental Results: Plasma and brain concentrations increased in a dose-dependent manner. Brain and cerebrospinal fluid Aβ levels were diminished (dose-dependently), with an essentially complete inhibition of the production of both peptides observed at the 100 mg/kg dose. Animal/Disease Models: Male SD (SD (Sprague-Dawley)) rat (250-300 g) [2]. Doses: 1 mg/kg Route of Administration: intravenous (iv) (iv)and oral; single. Experimental Results: Tmax was reached 12 hrs (hrs (hours)) after oral administration, and the bioavailability was 70 to 90%. Plasma clearance was shown to be less tha |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.83 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 (4.83 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.
