Transthyretin (TTR)

thyroxine-binding prealbumin

Transthyretin (TTR), formerly known as thyroxine-binding prealbumin, is a tetrameric protein transporting hormones in the plasma and brain. It forms a complex with retinol-binding protein (RBP), which facilitates the transport of thyroid hormones and vitamin A in the blood and cerebrospinal fluid. TTR is a positive indicator of nutrition status and is negatively correlated with inflammation. TTR is a neuroprotective and oxidative-stress-suppressing factor. The TTR structure is destabilized by mutations, oxidative modifications, aging, proteolysis, and metal cations, including Ca2+. Destabilized TTR molecules form amyloid deposits, resulting in senile and familial amyloidopathies.

    Gamma-Mangostin
    		Inhibitor 99.91%
    Gamma-Mangostin is a novel competitive 5-hydroxytryptamine 2A (5-HT2A) receptor antagonist and potent epoxidase 2 (COX-2) inhibitor, as well as a transthyroxin protein (TTR) profibrosis inhibitor. Gamma-Mangostin binds to the thyroxine (T4)-binding sites and stabilized the TTR tetramer. Gamma-Mangostin inhibits [3H] spiperone binding to cultured rat aortic myocytes (IC50=3.5 nM) and reduces The perfusion pressure response of rat coronary artery to 5-HT2A (IC50=0.32 μM). Gamma-Mangostin has anti-inflammatory, antibacterial, antioxidant and anticancer activities, and can be used in the study of metabolic disorders such as diabetes.

    Transthyretin-IN-3
    		Inhibitor
    Transthyretin-IN-3 (compound 6) is a designed benzofuran analogue. Transthyretin-IN-3 selectively binds to plasma transthyretin (TTR) to inhibit Amyloid aggregation (IC50=5.0±0.2 μM). Transthyretin-IN-3 can bind to TTR's thyroxine binding site specifically by carrying chlorine substituents at specific locations in its structure. This binding can prevent TTR tetramers from dissociating into unstable monomers.
