Product Introduction

Bioactivity
Description
L-Thyroxine sodium (LT4 sodium), the major hormone derived from the thyroid gland, is the agonist of Thyroid hormone receptor alpha and beta.
In vitro
evothyroxine (L-T(4))can upregulate the expression of P-gp mRNA and protein in LS180 cells, but only L-T(4) and L-T(3) can produce the same effect in Caco-2 cells, which are relatively lacking in PXR[1]
Cell Research
Cell lines: LS180V cells. Concentrations: 100 nM and 100μM. Incubation Time: 72 h. Method: LS180V cells are induced for 72 h with two l-T4 concentrations of 100 nM and 100 μM.
Animal Research
Animal Models: SD rats. Dosages: 20 μg/kg/day and 100 μg/kg/day. Administration: i.p.
AliasL-T4 sodium, LT4 sodium, Levothyroxine sodium

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
