Biochem/physiol Actions

LDN-27219 is a revesible inhibitor of transglutaminase 2 (TG2) that binds to the GTP binidng site of the enzyme and inhbits activity with and IC50 of 600 nM.
LDN-27219 is a thieno[2,3-d]pyrimidine-4-one-acylhydrazide derivative. Closed conformation of TG2 induced by LDN-27219 can be a potential therapeutic strategy for age-related vascular dysfunction and lowering blood pressure.

Transglutaminase 2 (TG2) is an enzyme which in the open conformation exerts transamidase activity, leading to protein cross-linking and fibrosis. In the closed conformation, TG2 participates in transmembrane signaling as a G protein. The unspecific transglutaminase inhibitor cystamine causes vasorelaxation

In the process of optimization, we developed a novel core skeleton of thieno[3,4-b]pyrazine via GK-13. The derivatives synthesized were shown to inhibit TGase 2 activity in cancer cells. Some of the hit compounds such as the arylethynyl group-coupled thieno[3,4-b]pyrazine derivatives
