Sulfhemoglobin (SHb) and methemoglobin (MHb) formations by various compounds were examined by single and three consecutive intraperitoneal administrations to mice.
With a single administration, methemoglobinemia was induced by diphenylamine (DPA), 1-naphthylamine (NA), phenylnaphthylamine (PNA), N-(1-naphthyl) anthranilic acid (N1) and N-(1'-naphthyl)-2-aminophenylacetic acid (IG240), and was not observed with phenylanthranilic acid (PAA), N-benzoyl-N'-phenyl-2, 6-diaminobenzoic acid (BPAA), flufenamic acid (FA), mefenamic acid (MFA), N-(2-6-dichlorophenyl) anthranilic acid (CPAA), N-(2', 6'-dichlorophenyl)-2-aminophenylacetic acid (CPPA), nine derivatives of N1 and two derivatives of IG240.

Crosslinking was partially prevented by metabolism of t-butyl hydroperoxide by the hexose monophosphate shunt except in methemoglobin-containing red cells where reaction with methemoglobin accounted for most of the consumption of t-butyl hydroperoxide.
Butylated hydroxytoluene, diphenylamine and ascorbate, compounds that inhibit t-butyl hydroperoxide-induced red cell membrane lipid peroxidation, had no effect on t-butyl hydroperoxide-induced membrane protein changes.

In addition, bactericidal activity was completely inhibited by the addition of the spin trap DMPO, as well as of other various radical scavengers (alpha-tocopherol and L-ascorbic acid), into the peroxide-heme iron system, but this effect was not observed with superoxide dismutase, beta-carotene, dimethyl sulfoxide, diphenylamine, or butylated hydroxyltoluene.
The major cytotoxic radical species generated in the mixtures of various peroxides and heme iron, especially methemoglobin, metmyoglobin, or hemin, was the alkyl peroxyl radical (ROO.).
