Description

PSEM 89S TFA is a selective and brain penetrant agonists for the resulting ion channels. PSEM 89S TFA is orthogonally selective for Q79G and L141F, respectively[1].

In Vitro

PSEM 89S (10 or 30μM) activates layer 2/3 cortical neurons expressing (Pharmacologically Selective Actuator Module) PSAML141F,Y115F-5HT3 high conductance (HC)[1].
PSEM 89S (10 μM) reversibly silenced transfected neurons by reducing cellular input resistance[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

PSEM 89S strongly reduces photostimulation-evoked feeding in mice expressing PSAML141F,Y115F- glycine receptor (GlyR) (30 mg/kg) but not in mice expressing only channelrhodopsin-2 (ChR2) (50 mg/kg)[1].
PSEM 89S (30 mg/kg) shows good brain penetrance in mice after minimally invasive intraperitoneal administration[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Agrp-cre mice (3-6 weeks)[1]
Dosage: 30 mg/kg
Administration: I.p. administration
Result: Almost completely suppressed fos (a marker of neuron activation) in ChR2-expressing neurons.
Animal Model: C57BL/6 mice[1]
Dosage: 30 mg/kg (Pharmacokinetic Analysis)
Administration: I.p. administration
Result: Rised rapidly in serum and brain, and was mostly cleared from both compartments in 1 h.

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: ≥ 2.5 mg/mL (6.18 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (6.18 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
