ln Vitro |
Baicalein (0-200 μM, 24 hours) can lower the levels of TNF-α and iNOS mRNA expression and decrease NO generation in LPS-activated RAW264.7 cells [1]. HT1080 is inhibited by baicalein (0-50 μM, 24 hours). In HT1080 cells, the expression of MMP-2, -9, and -14 as well as the activation of NF-κB are inhibited by scutellarein (0-50 μM, 24 hours) [3]. DPPH, ABTS+·, and ·OH have scavenging capabilities for baicalein (IC50 values of 16.84 μM, 3.00 μM, and 0.31 mM, correspondingly) [4].

ln Vivo |
In an HFD animal model, baicalein (50 mg/kg in diet for 16 weeks) demonstrated hepatoprotective, lipid-lowering, and anti-stress properties [2]. Baicalein, at doses of 50 and 500 mg/kg, controls the formation of tumors in the HT108 xenograft mouse model [3]. Neuronal damage can be mitigated and the neck's brain structure preserved by scutellarein (0–1.40 mmol/kg, neck) [5].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (7.27 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 20.8 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: ≥ 2.08 mg/mL (7.27 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 20.8 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.  (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
