Biological Activity
| Targets | IMP1; c-Myc; NF-κB |
| ln Vitro | Proteins encoded by target mRNAs are expressed more when the oncoembryonic mRNA binding protein IMP1 binds and stabilizes c-Myc, β-TrCP1, and other protein mRNAs [1]. In SK-MEL2 cells, BTYNB (10 μM; 0.5-1 hour) increases c-Myc mRNA and, in a dose-dependent manner, BTYNB (10-40 μM; 72 hours) lowers c-Myc expression [1]. 72-hour BTYNB (10–40 μM). In the presence of hormones, BTYNB (1-40 μM; 72 h) decreases CDC34, CALM1, β-TRCP1 and h) in T47D/(A1-2) cells and dose-dependently lowers IMP1 expression in SK-MEL2 cells [1]. The rapid proliferation of IMP1 cells is strongly inhibited by BTYNB, with IC50 values of 2.3 μM, 3.6 μM, and 4.5 μM in ES-2, IGROV-1, and SK-MEL2 cells, respectively. BTYNB did not suppress cell proliferation at any tested concentration, even 50 μM, and it had no effect on IMP1-negative cells [1]. |

Solubility Data
| Solubility (In Vitro) |
DMSO: ~62 mg/mL (~200.5 mM) Ethanol: ~4 mg/mL (~12.9 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.09 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 (8.09 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. Solubility in Formulation 3: ≥ 2.5 mg/mL (8.09 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
