Description

In Vitro

Phenytoin sodium is an antiepileptic agent. It is useful to treat partial seizures and generalized tonic-clonic seizures but not primary generalized seizures such as absence seizures or myoclonic seizures. Phenytoin is believed to protect against seizures by causing voltage-dependent block of voltage-gated sodium channels^[2].
Phenytoin has low affinity for resting sodium channels at hyperpolarized membrane potentials^[3].
When neurons are depolarized and the channels transition into the open and inactivated states, greater binding and block occur. The inhibitory potency is strongly use dependent, so that block accumulates with prolonged or repetitive activation, such as occurs during a seizure discharge. The blocking of sodium channels by phenytoin is of slow onset. The time course of fast sodium currents is therefore not altered in the presence of the drug and action potentials evoked by synaptic depolarizations of ordinary duration are not blocked. Thus phenytoin is able to selectively inhibit pathological hyperexcitability in epilepsy without unduly impairing ongoing activity. Phenytoin also blocks persistent sodium current and this may be of particular importance in seizure control. Phenytoin is a class 1b antiarrhythmic^[4].

In Vivo

Note:
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.

Phenytoin (60 mg/kg; once daily for 28 days) sodium reduces MDA-MB-231 cells in six-week-old female Rag2^-/-Il2rg^-/- mice^[1].
Phenytoin can induce a model of gingival hyperplasia in mice^[6].

Induction of Gingival Hyperplasia in Mice^[5]

Background

Phenytoin induced gingival overgrowth, a side effect with multifactorial aetiology, is characterized by an increase in the volume of extracellular tissues, particularly collagenous components, with varying degrees of inflammation.

Specific Modeling Methods

Mice: BALB/cByJ • male • 8 week old
Administration: 30 mg/kg • miniosmotic pumps • 0.5-μL/h • 2 weeks

Note

(1) Mice are housed for 1 week before any procedure for acclimation.
(2) Pumps are replaced every 2 weeks throughout the 12-week experimental period.
(3) Mice are then euthanized and heads are immediately placed in freshly made 4% paraformaldehyde for 24 hours for fixation.

Modeling Indicators

Morphology: Gingival overgrowth was apparent in the maxillary anterior gingival tissue of mice; Increased the papillary height and area.
Histomorphometry: Increased epithelial thickness and area in the maxillary anterior zone.
Molecular changes: Ccn2 is overexpressed in all regions of the epithelium; TGF-β1 and LOXL2 is overexpressed in both epithelial and connective tissues.

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: ≥ 2.5 mg/mL (9.12 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.
