Description

ML224 (NCGC00242364) is a selective TSHR antagonist with an IC50 value of 2.1 µM. ML224 can be used in the study of Graves' disease and other thyroid disorders.

IC50 & Target[1]

TSHR

2.1 μM (IC50)

LHR

>30 μM (IC50)

FSHR

>30 μM (IC50)

In Vitro

ML224 (0.001-100 μM; 20 min) exhibits half-maximal inhibitory doses of 2.1 μM for TSHR and greater than 30 μM for LH and FSH receptors in human embryonic kidney 293 cells[1].

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

Cell Viability Assay[1]

Cell Line: Human embryonic kidney 293 cells (stably expressing TSHRs, LHRs, or FSHRs)
Concentration: 0.001-100 µM
Incubation Time: 20 min
Result: Showed the IC50 for stimulation by bovine TSH (1.8 nM) was 2.1 µM.
Showed inhibition of LH and FSH stimulation was less than 15% for LH (1 nM) and less than 30% for FSH (1 nM) at 30 µM.
In Vivo

ANTAG3 (2 mg/mice; i.p. via osmotic pump; single daily for 3 days) lowers serum FT4 levels and thyroidal mRNAs for TPO and NIS in mice continuously stimulated by TRH[1].

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

Animal Model: Female BALB/c mice (8 to 13-week-old; ~18.7 g)[1].
Dosage: 2 mg/mice
Administration: Intraperitoneal injection via osmotic pump; single daily for 3 days
Result: Lowered the levels of FT4 by 44%, and the levels of TPO and NIS mRNAs by 75% and 83%, respectively.

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: ≥ 2.5 mg/mL (4.76 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.
  • Protocol 2

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

    Solubility: ≥ 2.5 mg/mL (4.76 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
  • 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.
