General description
A cell-permeable, dihydroisoxazole compound that acts as an active-site directed, acyl-donor substrate competitive inhibitor of transglutaminase 2 (TG2, Ki = 11 µM). Shown to bind to the active site cysteine. Blocks 5-biotinylamido pentylamine (5BP)-induced TG2 activation in C57BL/6 mice lung in a dose-dependent manner and reduces hypoxia-induced pulmonary hypertension. Blocks poly(I:C)-induced TG2 activity in small intestine without affecting villous atrophy. Exhibits good selectivity over TG3 and Factor XIIIa, but has equipotent effect on TG1. It is well-tolerated by mice (~50 mg/kg) and displays moderate pharmacokinetic properties with t1/2= 12 h.
Please note that the molecular weight for this compound is batch-specific due to variable water content.
