In Vitro

Teriflunomide primarily acts as an inhibitor of dihydroorotate dehydrogenase (DHODH), a key mitochondrial enzyme involved in the de novo synthesis of pyrimidines in rapidly proliferating cells. By reducing the activity of high-avidity proliferating T lymphocytes and B lymphocytes, teriflunomide likely attenuates the inflammatory response to autoantigens in MS. Thus, teriflunomide can be considered a cytostatic rather than a cytotoxic drug to leukocytes^[1].

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

In Vivo

Teriflunomide has demonstrated beneficial effects in two independent animal models of demyelinating disease. In the dark agouti rat model of experimental autoimmune encephalitis (EAE), teriflunomide administration results in clinical, histopathological, and electrophysiological evidence of efficacy both as a prophylactic and therapeutic agent. Similarly, in the female Lewis rat model of EAE, teriflunomide administration results in beneficial prophylactic and therapeutic clinical effects, with a delay in disease onset and symptom severity^[1].

The CC₅₀, EC₅₀, and SI for six compounds against FIPV. The half-maximal cytotoxic concentration (CC₅₀) values are from four measurements of diluted drugs using MTT assay, in CRFK cells treated with drugs for 48 h. The half-maximal effective concentration (EC₅₀) values are from six measurements of diluted drugs against FIPV replication in CRFK cells for 48 h. Based on the SI value (mean CC₅₀)/(mean EC₅₀), GS-441524 was found highly selective (SI 165.5) against FIPV among the drugs tested and showed high efficacy (EC₅₀ 1.6 µM) against FIPV with a less deleterious effect (CC₅₀ 260.0 µM) on the cells. Nirmatrelvir also showed promising efficacy (EC₅₀ 2.5 µM) and selectivity (SI 113.7) against FIPV. Ritonavir showed the highest toxicity level in the cells (CC₅₀ 39.9).

Stock Solution Working Solution

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 (9.25 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.

Protocol 2

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

Solubility: ≥ 2.5 mg/mL (9.25 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 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 (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
