The lipid peroxidation potential of benzanthrone in different subcellular organelles of liver was examined to elucidate the basis of benzanthrone induced hepatotoxicity. Male Wistar albino rats were given an intraperitoneal injection of benzanthrone oat 40 mg/kg daily for 3 consecutive days. The animals were killed 24 hours after the last treatment. Livers were removed for the preparation of subcellular fractions. Hepatic homogenate and subcellular fractions from control and treated rats were assayed for lipid peroxidation by determining the formation of malonaldehyde. The subcellular fractions included cell debris, nucleus, mitochondria, microsome, and cytosol. Protein content was determined as well. Benzanthrone caused statistically significant enhancements in NADPH dependent enzymatic and nonenzymatic hepatic lipid peroxidation in whole homogenate, nuclear, mitochondrial, and microsomal fractions. Benzanthrone induced a significant increase of 212 and 68% in the mitochondrial and microsomal fractions, respectively. A significant increase of 116, 91, and 67% in whole homogenate, mitochondrial, and microsomal fractions was induced by benzanthrone on prooxidant free nonenzymatic lipid peroxidation. Benzanthrone significantly enhanced prooxidant free FeSO4/ADP and ascorbate mediated nonenzymatic lipid peroxidation in hepatic in Fe(+2)/ADP and ascorbate dependent lipid peroxidation was also evident in the nuclear fraction. Increased production of lipid peroxides in nuclear, mitochondrial, and microsomal fractions suggested that these membranes were the vulnerable sites for benzanthrone induced toxicity.

The bioelimination and organ retention of (14)C benzanthrone, an anthraquinone dye intermediate, were determined in rats, mice and guinea pigs. Urinary excretion of benzanthrone during 96 hours was higher in guinea pigs (28%) compared with rats and mice (19%). However, fecal elimination during 96 hours was higher in rats (39%) and mice (42%) than in guinea pigs (25%). Urinary elimination of benzanthrone in rats and mice was highest between 12 and 24 hours. The maximum amount of radiolabelled benzanthrone was eliminated through feces at 24-48 hours in all the three animal species. The retention of (14)C benzanthrone in the liver was comparable in rats (11.2%) and mice (11.9%), while in guinea pigs it was substantially higher (21.9%). The testes of rats and mice were devoid of radioactivity, whereas those of guinea pigs showed a marginal retention (1.25%) of (14)C. The present study suggests that guinea pigs are more prone to benzanthrone toxicity than are rats and mice since the bioelimination of this compound is slower and its organ retention is higher in this species.
