Metyrapone, alpha-naphthoflavone, phenelzine, mercuric chloride, and nitrogen significantly inhibited the reaction indicating the involvement of the cytochrome P-450 monooxygenase.

Covalent binding was inhibited by inhibitors of cytochrome P-450.
Low molecular weight thiols (GSH, cysteine and cysteamine), a thiol generator (methylthiazolidine carboxylate), and thiol modifying agents (N-ethylmaleimide, mercuric chloride and diamide) significantly inhibited covalent binding.

A concentration of 24 mumol.L-1 cadmium acetate and 2.5 mumol.L-1 mercuric chloride also inhibited the signal significantly as compared with the control.

Activities of heme oxygenase and tryptophan-2,3-dioxygenase and cytochrome P450 content in liver as well as absorption of the Soret band and optical density at 280 nm in serum were determined 2 and 24 h after administration of HgCl (2) and CoCl (2) and after co-administration of the metal salts with alpha-tocopherol.

These results suggested that nNOS was more stable as to exposure to sodium cholate, mercury chloride or urea in comparison to microsomal cytochrome P-450, which may be due to the different heme environment and protein structure.
