Nor-NOHA acetate

Nor-NOHA acetate (Nω-Hydroxy-nor-L-Arginine acetate, N-OMega-hydroxy-L-norarginine acetate, N-Hydroxy-nor-L-arginine acetate) is a reversible, competitive inhibitor of arginase. Nor-NOHA inhibits arginase activity in aorta with an IC50 of less than 1 μM, that is, similar to its effects on liver arginase (IC50 = 0.5 μM) .
