Biological Activity
| ln Vitro | β-Aescin (mainly composed of aescin Ia and aescin Ib) is the primary active component of extract made from horse chestnut seeds. β-Aescin has the ability to suppress the growth and/or trigger programmed cell death in a number of cancer cell types, such as A549, HT-29, HCC, OVCAR3, and H-Ras 5RP7 cells. β-Aescin exhibits potential as a chemopreventive drug, particularly in the case of cancers linked to inflammatory reactions [1]. α-aescin, which consists primarily of isoescin Ia and isoescin Ib, is a small component of aescin with modest biological activity [1]. |

isoescin Ib has been reported in Aesculus chinensis and Aesculus hippocastanum with data available. See also: Horse Chestnut (part of). |
Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~88.40 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (2.21 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 (2.21 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 (2.21 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.) |
