Thyroid hormone receptor antagonist (1-850)
Based on 1 Customer Validation
Thyroid hormone receptor antagonist (1-850) is a competitive, selective and high-affinity thyroid hormone receptor (TR) antagonist with an IC50 of 1.5 μM for antagonizing the effect of T3 on TR. Thyroid hormone receptor antagonist (1-850) blocks T3-mediated interaction of TRα and TRβ with nuclear receptor coactivator. Thyroid hormone receptor antagonist (1-850) has no effect on the activity of RARα.

Biological Activity
Thyroid hormone receptor antagonist (1-850) (10 μM; for 7 days) abolishes the increase in the expression of nestin mRNA induced by Retinoic Acid (RA; HY-14649; 1 μM) [2].
Thyroid hormone receptor antagonist (1-850) (0.1-20 μM; 24 h) effectively blocks IGF1 mRNA expression while increases D2 mRNA expression in Organotypic tilapia liver cultures[3].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.39 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.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
