Biochem./physiol. Wirkung

R283 (NTU283; Rob283) is a cell-permeable 2-[(2-oxopropyl)thio] imidazolium derivative that acts as an irreversible inhibitor against factor XIIIa (FXIIIa) and transglutaminase 2 (TG2, TGase II) by targeting FXIIIa and TG2 active site cysteine (Cys) for acetonylation in a selective manner with little glutathione (GSH) inhibitory potency (app 2nd order rate const = 23000/M/s, 19000/M/s, 0.12/M/s, respectively). A useful tool for investigating TG2-mediated cellular functions (typical conc. range: 25-500 μM).

In celiac disease (CD), transglutaminase type II (TG2) has 2 fundamental roles: (1) as the autoantigen recognized by highly specific autoantibodies and (2) the modifier of pathogenic gliadin T-cell epitopes. It follows that inhibition of TG2 might represent an attractive

In view of the facts that tTG protein expression level and its enzyme activity increase in AD brains of both individuals and transgenic animals and compelling evidence of the involvement of inflammation in AD pathogenesis, tTG could be involved in

Deposition of amyloid-beta (Aβ) peptides has been shown to induce the release of inflammatory factors by activated microglia and brain infiltrating monocytes/macrophages. Interestingly, the enzyme transglutaminase 2 (TG2) has been shown to play a key role in neuroinflammation and regulation

The physiologic role of several transglutaminases could be more precisely defined with the development of specific inhibitors for these enzymes. In addition, specific plasma transglutaminase (fXIIIa) inhibitors may have therapeutic utility in the treatment of thrombosis. For these purposes, the
