Ladostigil hemitartrate  (Synonyms: TV-3326 hemitartrate)

Cat. No.: HY-10400 Purity: 98.90%
Handling Instructions Technical Support

Ladostigil (TV-3326) hemitartrate is an orally active dual inhibitor of cholinesterase and brain-selective monoamine oxidase (MAO) that can cross the blood-brain barrier, with IC50s of 37.1 and 31.8 μM for MAO-B and AChE, respectively. Ladostigil hemitartrate exhibits neuroprotective, antioxidant and anti-inflammatory activities. Ladostigil hemitartrate can be used for the research of depression and Alzheimer's disease. Ladostigil (hemitartrate) is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Description

Ladostigil (TV-3326) hemitartrate is an orally active dual inhibitor of cholinesterase and brain-selective monoamine oxidase (MAO) that can cross the blood-brain barrier, with IC50s of 37.1 and 31.8 μM for MAO-B and AChE, respectively. Ladostigil hemitartrate exhibits neuroprotective, antioxidant and anti-inflammatory activities. Ladostigil hemitartrate can be used for the research of depression and Alzheimer's disease[1][2]. Ladostigil (hemitartrate) is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

IC50 & Target[1]

MAO-B

37.1 nM (IC50)

AChE

31.8 nM (IC50)

In Vitro

Ladostigil (1-10 μM) hemitartrate exerts neuroprotective activities, including a prevention of the fall of the mitochondrial membrane potential (ψ), attenuation of apoptotic cascades and an inhibition of ROS production induced by OS insults[2].
Ladostigil (1-10 μM) hemitartrate has a significant neuroprotective activity, including inhibition of caspase-3 activation, induction of Bcl-2 and reduction of Bad and Bax gene and protein expression in human neuroblastoma SK-N-SH cells[2].

In Vivo

Ladostigil (17 mg/kg; p.o. daily for 6 weeks) hemitartrate abolishes their hyperanxiety and depressive-like behaviour in the elevated plus maze (EPM) and forced swim tests (FST) tests in adulthood from puberty to prenatally-stressed rats[4].
Ladostigil (50 μmol/kg; single p.o.) hemitartrate restores the loss of episodic memory in the object recognition test in rats[3].

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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 1.25 mg/mL (3.60 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

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

    Solubility: ≥ 1.25 mg/mL (3.60 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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.

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.
