Analysis results revealed that none of the herbicide treatments fitted the pyrenophorol model and indicate that the effect of the phytotoxin on A. sterilis differs than those caused by glyphosate, mesotrione, norflurazon, oxadiazon, paraquat, and diuron, which inhibit 5-enolpyruvylshikimate-3-phosphate synthase, 4-hydroxyphenyl-pyruvate-dioxygenase, phytoene desaturase, protoporphyrinogen oxidase, photosystem I, and photosystem II, respectively.

In a separate experiment, male ICR mice were fed 1000 ppm of the protoporphyrinogen oxidaseinhibiting herbicide oxadiazon in the diet for 10 days.

The growth of resistant cells was also insensitive to oxadiazon [5-tert-butyl-3-(2,4-dichloro-5-isopropoxyphenyl)-1,3,4-oxadiazol-2-(3H)- one], the other chemical class of Protox inhibitor.

IR 5790, an arylthiadiazolone herbicide structurally related to oxadiargyl and oxadiazon, was synthesized.
The phenotypic responses of susceptible plants, such as interruption of growth and light-dependent development of necrotic areas on the foliage, are consistent with those observed with protoporphyrinogen oxidase-inhibiting herbicides.

Administration of the protoporphyrinogen oxidase inhibitor oxadiazon (12.5 mg/kg/day) for four days to male Wistar rats caused a partial block of porphyrin biosynthesis, thus mimicking the condition of quiescent variegate porphyria.

The specific binding of the herbicide acifluorfen 5-[2-chloro-4-(trifluoromethyl) phenoxy]-2-nitrobenzoic acid to corn etioplast membranes is competitively inhibited by protoporphyrinogen IX, the substrate of protoporphyrinogen oxidase.
Three other peroxidizing molecules, oxadiazon [5-terbutyl-3-(2,4-dichloro-5-isopropoxyphenyl)-1,3,4-oxadiazol -2-one], LS 82556 [(S) 3-N-(methylbenzyl) carbamoyl-5-propionyl-2,6-lutidine], and M&B; 39279 [5-amino-4-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl) pyrazol], also compete with acifluorfen for its binding site.

Administration of oxadiazon or oxyfluorfen (1000 ppm in the diet) to male BALB/c mice for 9 days resulted in experimental porphyria, resembling the acute phase of human variegate porphyria.
Both herbicides caused a decrease of protoporphyrinogen oxidase activity in liver and kidney.
