Hematein (Haematein) is a oxidized analogue of Hematoxylin used as a dye. As an oxidation product of hematoxylin, it acts as an allosteric casein kinase II inhibitor with an IC50 of 0.74 μM. Hematein has anticancer activity by inhibiting Akt/PKB Ser129 phosphorylation and the Wnt/TCF pathway, and increasing cancer cell apoptosis.
| ln Vitro |
In A427 lung cancer cells, hematein (10–100 μM; 14 days) suppresses cell growth[1]. Hematein (50 and 100 μM; 48 hours) causes A427 lung cancer cells to undergo apoptosis[1]. 48 hours) suppresses Akt phosphorylation that is unique to CK2[1].

|---|---|
| ln Vivo |
In A427 lung cancer cell xenografts, hematein (intraperitoneal injections; 50 mg/kg; twice weekly for 6 weeks) suppresses tumor growth[1].

| Solubility (In Vitro) |
DMSO : ~100 mg/mL (~333.04 mM)

|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.33 mM) (saturation unknown) in 10% DMSO + 40% PEG300 +5% Tween-80 + 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. (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 3.3304 mL | 16.6522 mL | 33.3045 mL | |
| 5 mM | 0.6661 mL | 3.3304 mL | 6.6609 mL | |
| 10 mM | 0.3330 mL | 1.6652 mL | 3.3304 mL |
*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.
