Teprotumumab is a human monoclonal antibody that blocks the IGF-1 receptor (IGF-1R). Teprotumumab binds to the extracellular α-subunit domain ligand of IGF-1R. Teprotumumab inhibits TSH and IGF-1 action in fibrocytes. Teprotumumab reduces TSH-dependent IL-6 and IL-8 expression and Akt phosphorylation. Teprotumumab can be used in the study of thyroid-associated eye diseases.

TSHR antagonist S37a is a selective, orally bioavailable TSHR (thyroid-stimulating hormone receptor) antagonist that inhibits TSH-induced cyclic adenosine monophosphate (cAMP) in TSHR-expressing HEK 293 cells, suitable for studying Graves' orbitopathy.

Org 274179-0 is an effective allosteric antagonist of the thyroid-stimulating hormone (TSH) receptor, with an IC50 in the nanomolar range. It fully inhibits TSH (and TSI)-mediated activation of the TSH receptor with minimal impact on the efficacy of TSH. This compound can be utilized in studies of Graves' disease (GD).

Org 274178-0 is a selective antagonist of the thyroid-stimulating hormone receptor (TSHR), with a pIC50 value of 5.03 for TSHR. It inhibits the activation of the cAMP and phospholipase C (PLC) signaling pathways mediated by thyroid-stimulating hormone (TSH) and TSH receptor-stimulating immunoglobulins (TSIs). Org 274178-0 shows potential for research in Graves' disease and Graves' ophthalmopathy.

MS437 is a potent TSH receptor agonist.

MS438 is an effective agonist of the TSH receptor.

Anti-TSHR Antibody (M22) is a and highly specialized stimulating monoclonal antibody that targets the thyrotropin receptor (TSHR) to mimic the biological activity of thyroid-stimulating hormone and facilitate the measurable activation of cyclic AMP signaling pathways across various endocrine and immunological experimental models.

PGlu-3-methyl-His-Pro-NH2 TFA enhances binding to pituitary TRH receptors, thereby increasing the stimulation of thyroid-stimulating hormone (TSH) release from the pituitary.

NCATS-SM4420 (Compound A35) is an orally effective ligand for the thyroid-stimulating hormone receptor (TSHR) that inhibits the proliferation of MDA-T32 and MDA-T85 cells both in vitro and in vivo, with IC50 values of 0.71 μM and 0.38 μM, respectively. Additionally, it suppresses the metastasis of MDA-T85F1 in mice. NCATS-SM4420 holds potential for research in the field of thyroid cancer.

TSHR antagonist S37b, the less potent enantiomer of TSHR antagonist S37a, exhibits minimal efficacy in inhibiting the thyrotropin receptor (TSHR). It is utilized in thyroid function research[1].

Benzylthiouracil (6-Benzyl-2-thiouracil) induces ANCA-associated glomerulonephritis in Graves' disease patients and is used to study hyperthyroidism.

K1-70 is a humanized antibody targeting TSHR, used in the study of autoimmune diseases and endocrine disorders.

Thyrotropin (TSH), a thyroid-stimulating hormone, is synthesized by thyrotrope cells in the anterior pituitary gland and modulates the endocrine activity of the thyroid [1] [2].

Pentacosafluorotridecanoic Acid (PFTrDA) is a perfluoroalkyl substance (PFAS) that exhibits various biological impacts across different species. In zebrafish embryos, exposure to PFTrDA induces yolk sac edema and increases mRNA expression of thyroid hormone synthesis genes, including tshβ, at concentrations of 0.1 and 0.3 mg/L. At a dosage of 10 mg/kg, PFTrDA reduces serum testosterone and luteinizing hormone levels, as well as palmitic acid, linoleic acid, and oleic acid levels in the testicular interstitial cells of late adolescent rats. In humans, maternal plasma levels of PFTrDA during pregnancy are positively correlated with the development of eczema in female infants (but not male infants), and PFTrDA levels are higher in the livers of cancerous humans compared to non-cancerous ones. Additionally, PFTrDA is found in marine mammals.

SYD5115 is an orally active TSH-R antagonist.

ADX61623 is an effective negative allosteric modulator (NAM) of the follicle-stimulating hormone receptor (FSHR). It also exhibits activity on the luteinizing hormone receptor (LH-R) but is inactive on the thyroid-stimulating hormone (TSH) receptor. ADX61623 can be utilized in research on estrogen-dependent diseases.
