Nitroxyldisulfonate [Fremy's salt; (KSO3)2NO.] and bisulfite (NaHSO3) have abolished periodic acid (H5IO6)-induced blastogenesis of human peripheral blood lymphocytes (HPBL), but only inhibited the blastogenic response of H5IO6-oxidized rat and mouse lymphocytes, as determined by the rates of nucleic acids synthesis...

Bisphenol A was oxidized to monoquinone and bisquinone derivatives by Fremy's salt, a radical oxidant, though salcomine and alkali did not catalyze the oxidation by molecular oxygen. Bisphenol A, bisphenol B, and 3,4'-(1-methylethylidene)bisphenol were converted to their monoquinone derivatives in...
