In MCF-10A cells (stimulated by EGF), CR-1-31-B (100 nM; 24 hours) suppresses MUC1-C translation [1]. MUC1-C abundance is decreased in MDA-MB-468 breast cancer cells by CR-1-31-B (10 and 100 nM) [1]. By translating down c-FLIP, CR-1-31B makes gallbladder cancer cells more susceptible to TRAIL-mediated apoptosis [2]. When treated with synthetic Rocaglate CR-1-31-B (24–72 hours), neuroblastoma (NB) cell lines show decreased viability, increased apoptosis rate, and changes in cell cycle distribution. A translational barrier is created when eIF4A and eIF4F are clamped onto mRNA [4]. In pancreatic cancer cells, treatment with CR-1-31-B (100 nM; 5 hours) enhances glutamine countermetabolism [5].

| ln Vivo |
CR-1-31-B (2 mg/kg in 60 μL olive oil; i.p.; every 2 days for 28 days) in a BALB/c nude mouse model of gallbladder cancer cells Apoptosis of cells (GBC) inhibits growth and starts TRAIL induction[2]. Protein synthesis and pancreatic tumor growth are effectively inhibited by CR-1-31-B (0.2 mg/kg; intraperitoneal injection; once daily for 7 days; pancreatic ductal adenocarcinoma mouse orthotopic transplantation model) [5].

Western Blot Analysis[1]
Cell Types: MCF-10A cells (EGF-stimulated) Tested Concentrations: 100 nM Incubation Duration: 24 hrs (hours) Experimental Results: Blocked increases in MUC1-C abundance. Cell Viability Assay[4] Cell Types: SH-SY5Y cells and Kelly cells Tested Concentrations: 0.1-100 nM Incubation Duration: 24-72 hrs (hours) Experimental Results: A significant decrease in SH -SY5Y viability was observed at 10 nM for all time points. Dramatically diminished the viability of Kelly cells at 5 nM. The calculated IC50 at 48 h was 20 nM for SH-SY5Y and 4 nM for Kelly cells. Apoptosis Analysis[4] Cell Types: SH-SY5Y and Kelly cells Tested Concentrations: SH-SY5Y cells were treated with 10, 20, and 50 nM and Kelly cells with 1, 5, and 10 nM Incubation Duration: 24-72 hrs (hours) Experimental Results: Triggered apoptosis. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 5.75 mg/mL (11.33 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 57.5 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: ≥ 5.75 mg/mL (11.33 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 57.5 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.
