Biological Activity
transketolase[1]
Arginase inhibitor 1inhibits human arginases I and II with IC50s of 223±22.3 and 509±85.1 nM, respectively, and is active in a recombinant cellular assay overexpressing human arginase I (CHO cells). Arginase inhibitor 1 is a novel second generation arginase inhibitor with significant activity in a rat model of myocardial ischemia/reperfusion injury (MI/RI). Arginase inhibitor 1 is potent against hARG I in both in vitro enzyme and cellular assays. The IC50 for Arginase inhibitor 1 is 8 μM in CHO Cells Over-Expressing hArgI[1].
