The TSH receptor (TSHR) is a member of the glycoprotein hormone receptors, a subfamily of family A G protein-coupled receptors. The TSH receptor (TSHR) undergoes complex post –translational modifications including intramolecular cleavage and receptor multimerization. TSHR and its endogenous ligand thyrotropin (TSH) are of essential importance for growth and function of the thyroid gland and proper function of the TSH/TSHR system is pivotal for production and release of thyroid hormones.

The TSHR activates different G-protein subtypes and signaling pathways, whereby Gs- and Gq-induced signaling are probably of highest importance. TSH and its receptor are required for thyroid hormone synthesis and release in the thyroid gland. Dysfunctions of the TSHR are the underlying cause of various gain- or loss-of-function phenotypes associated with thyroid malfunction. It has been suggested that the TSHR is involved in the development and mechanisms of ophthalmopathy. TSHR is also a major autoantigen for autoimmune diseases of the thyroid gland. In addition, TSHR has been proposed to be a potent target against thyroid cancer with several experimental compounds under development.

  • HY-N0526R
    2"-O-Galloylhyperin (Standard)
    		Inhibitor
    2"-O-Galloylhyperin (Standard) is the analytical standard of 2"-O-Galloylhyperin (HY-N0526). This product is intended for research and analytical applications. 2''-O-Galloylhyperin is an active natural compound with anti‑inflammatory, antioxidant, anti‑adipogenic, antifibrotic, and cytostatic activities. 2''-O-Galloylhyperin upregulates SIRT1/Nrf2 signaling, inhibits NF-κB and MAPK (ERK1/2, p38, JNK) phosphorylation, suppresses TSHR activation, reduces ROS accumulation, and enhances SOD and GSH-Px activities. 2''-O-Galloylhyperin protects against LPS-induced tissue injury, enhances survival, and inhibits adipogenesis and fibrosis. 2"-O-Galloylhyperin can be used for the research of sepsis, acute lung injury, and thyroid eye disease.
