Bufalin is a novel and potent inhibitor of steroid receptor coactivator 3 (SRC-3) with anticancer, anti-inflammatory and antinociceptive activity. It is a naturally occurring digoxin-like immunoreactive component isolated from the Chinese medicine Chan Su. It exerts anticancer activity by inducing cell death through the ROS-mediated RIP1/RIP3/PARP-1 pathways.
ln Vitro |
In NCI-H460 cells, bufalin (0, 1, 2, 4 μM) reduces cell viability for 48 hours[2]. Bufalin (2 μM) decreases the expression of GRP78 mRNA while increasing that of caspae-3, Endo G, and GADD153 mRNA[2].

ln Vivo |
Mice harboring NCI-H460 cells demonstrated notable antitumor activity when bufalin (0.1, 0.2, or 0.4 mg/kg, intraperitoneally injected once daily for 14 days) was administered [2].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.47 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 2: ≥ 2.5 mg/mL (6.47 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. View More
Solubility in Formulation 3: ≥ 2.08 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. |

*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.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
