Description

PD 198306 is a selective MAPK/ERK-kinase (MEK) inhibitor. PD 198306 results in an observable reduction in the Streptozocin induced increase in the level of active ERK1 and 2. Antihyperalgesic effects[1].

In Vitro

PD198306 significantly inhibits Tha-GFP replication by 25% at 10 μM, after 36 h[2].
PD198306 (5 μM) reduces Tha-Crimson replication significantly by 20% at 18 h but such a result could not be confirmed at 36 h[2].

Cell Cycle Analysis[2]

Cell Line: Human induced pluripotent stem cells (iPSC)
Concentration: 10  μM
Incubation Time: 6  hours
Result: Inhibited Tha-Crimson replication at 10 μM, reducing it by 30% at 18 h and 50% at 36 h.
In Vivo

Intrathecal administration of PD 198306 (1-30 μg per 10 μL) dose-dependently (1-30 μg) blocks static allodynia in both the streptozocin and the chronic constriction injury (CCI) models of neuropathic pain[1].

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

Animal Model: Male Sprague Dawley rats (250-300 g) bearing neuropathic pain[1]
Dosage: 1-30 μg per 10 μL and 3 mg per 100 μL (PD 198306 is suspended in cremophor:ethanol:water, 1 : 1 : 8.)
Administration: Single doses of intrathecal (i.t.) or intraplantar (ipl) of PD 198306 (1-30 μg per 10 μL and 3 mg per 100 μL respectively
Result: Intrathecal administration dose-dependently (1-30 μg) blocked static allodynia the streptozocin model of neuropathic pain.
The minimum effective doses (MED) of 3 μg significantly blocked static allodynia 30 min after treatment.
Both 10 μg and the highest dose used (30 μg) totally blocked the maintenance of static allodynia, for up to 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: ≥ 5 mg/mL (10.50 mM); Clear solution

    This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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% Corn Oil

    Solubility: ≥ 5 mg/mL (10.50 mM); Clear solution

    This protocol yields a clear solution of ≥ 5 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 (50.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
