E6 Berbamine
E6 Berbamine (Berbamine p-nitrobenzoate) is a potent calmodulin (CaM) antagonist. E6 Berbamine inhibits the activities of calmodulin-dependent myosin light chain kinase (MLCK) and phosphodiesterase (PDE). E6 Berbamine exhibits anti-leukemic activity. E6 Berbamine can be used in research related to cardiovascular abnormalities and chronic myeloid leukemia.

In Vitro
E6 Berbamine (2 min) acts as a competitive calmodulin (CaM) antagonist, potently inhibiting CaM-activated myosin light chain kinase (MLCK) activity in chicken gastric tissues, with a Ki of 0.95 μM and an IC50 of 8 μM[1].
E6 Berbamine binds directly to dansyl-labeled porcine brain CaM bound to Ca2+, with a Ki of approximately 1 μM[1].
E6 Berbamine inhibits the activity of calmodulin-dependent phosphodiesterase with an IC50 of 0.53 μM[1].
E6 Berbamine (Compound 3n) inhibits the activity of K562 cells with an IC50 value of 2.13 μM[2].

Lösungsmittel & Löslichkeit
In Vitro:
DMSO : 100 mg/mL (131.96 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Konzentration (Stammlösung) × Volumen (Stammlösung) = Konzentration (Ziellösung) × Volumen (Ziellösung)
In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (3.30 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (3.30 mM); Suspended solution
This protocol yields a suspended solution of ≥ 2.5 mg/mL (saturation unknown). Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
