Background:

N6022 is a specific and fully reversible inhibitor of S-nitrosoglutathione reductase (GSNOR) with IC50 value of 8nM [1].

N6022 is a first-in-class inhibitor of GSNOR. Inhibition of GSNOR causes the accumulation of GSNO which acts as a vasodilator and anti-inflammatory factor. N6022 presents an IC50 value of 8nM in the GSNO reduction assay and 32nM in the HMGSH oxidation assay. The Ki values are 2.5nM and 3.1nM, respectively. N6022 is selective against GSNOR over other human ADH enzymes. The IC50 values are 21μM, 67μM and 0.5μM for ADH IB, ADH II and ADH IV, respectively. N6022 also shows no effect on the NADPH-dependent enzyme, human carbonyl reductase, with IC50 value of 221μM. Currently, N6022 is under clinical studies for the treatment of inflammatory lung diseases [1].
