Product Description
Binds strongly to flavoproteins and is thus a powerful and specific inhibitor of several important enzymes, including nitric oxide synthase (NOS), NADPH-ubiquinone oxidoreductase, NADPH oxidases and NADPH cytochrome P450 oxidoreductase. Nitric oxide synthase, which shows significant homology with cytochrome P450 reductase, has shown to be irreversibly inhibited by this compound.
