Timosaponin AIII is a novel and potent acetylcholinesterase (AChE) inhibitor (IC50 = 35.4 μM) and also an inhibitor of U46619-induced rat platelet aggregation.
| ln Vitro |
Acetylcholinesterase (AChE) activity is inhibited by timosaponin AIII, with an IC50 of 35.4 μM[1]. The primary selective cytotoxic effect of BN108 is thought to be mediated by timosaponin AIII, which also induces ER stress, protective autophagy, and mTOR inhibition [2].

| ln Vivo |
Timosaponin AIII (TA3) was the most successful steroidal saponin in addressing memory impairments among those that were examined. Scopolamine-induced step delay reduction was enhanced by timosaponin AIII by 17% (10 mg/kg), 28% (20 mg/kg), and 43% (40 mg/kg). During acquisition trials, no variations in latency were noticed. The efficient inhibition of acetylcholine decrease in the brains of mice treated with scopolamine is achieved by timosaponin AIII (20, 40 mg/kg, po). Timosaponin AIII's inhibitory effect is similar to that of tacrine, which is employed as a positive control [1].

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (2.81 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. Solubility in Formulation 2: ≥ 2.08 mg/mL (2.81 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 20.8 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.) |

*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.
