Description

Timosaponin AIII could inhibit acetylcholinesterase (AChE) activity, with an IC50 of 35.4 μM.

IC50 & Target

AChE

 

In Vitro

Timosaponin AIII could inhibit acetylcholinesterase (AChE) activity, with an IC50 of 35.4 μM[1]. Timosaponin AIII is identified as a major selective cytotoxic activity in BN108, and its selective cytotoxic activity involves inhibition of mTOR, induction of ER stress and protective autophagy[2].

In Vivo

Of the tested steroidal saponins, Timosaponin AIII (TA3) most potently improves memory deficits. Timosaponin AIII increases the scopolamine-induced reduction in step-through latency by 17% (10 mg/kg), 28% (20 mg/kg), and 43% (40 mg/kg). During the acquisition trial, no differences in latent time are observed. Timosaponin AIII (20, 40 mg/kg, p.o.) potently inhibits this reduction of acetylcholine in scopolamine-treated mouse brain. The inhibitory effect of Timosaponin AIII is comparable to that of tacrine, which is used as a positive control[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (2.81 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.08 mg/mL (2.81 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL Corn oil, and mix evenly.

Animal Administration

Mice[1]
Male ICR mice weighing 28-30 g are used. For the acquisition trial, mice are initially placed in the illuminated compartment and the door between the two compartments is opened 10 s later. Each group contains ten mice. One hour or 5 h before the acquisition trial, mice receive each test agent (e.g., Timosaponin AIII 10, 20 or 40 mg/kg, p.o. ). One hour before the acquisition trial, mice receive tacrine (10 mg/kg, p.o.) as a positive control. Memory impairment is induced by scopolamine treatment (1 mg/kg, i.p.) 0.5 h or 4.5 h after the administration of test agents, tacrine, or 10% Tween 80 solution. Control animals are administered 10% Tween 80 solution alone. Twenty-four hours after the acquisition trial, the mice are again placed in the illuminated compartment for retention trials. The time taken for a mouse to enter the dark compartment after the door opened is measured as the latency time in both acquisition and retention trials, with a maximum of 300 s[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
