Replaces Prod. #: ALX-270-003
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 been shown to be irreversibly inhibited by this compound in cultured peritoneal macrophages (IC50=30nM).
