AFTER ORAL ADMIN OF (14)C-LABELED DICHLORAN TO MALE RATS, DICHLORAN WAS ... METABOLIZED, & EXCRETED WITH 89% OF THE LABEL IN THE URINE. ... 24 HR URINE POOLS CONTAINED ONLY FREE & CONJUGATED 2,6-DICHLORO-4-HYDROXYANILINE (DCHA); 1 DICHLORAN: 1 DICHLORAN GLUCURONIDE; 6 DICHLORAN SULFATE. HYDROLYSIS OF THE URINE SHOWED TWO COMPOUNDS IN ADDITION TO TRACES OF STARTING MATERIAL. 4-AMINO-3,5-DICHLOROPHENOL ACCOUNTED FOR 70% OF THE URINARY RADIOACTIVITY; 4-AMINO-2,6-DICHLOROANILINE FOR ABOUT 2.4%. SMALL AMOUNTS OF AN ARYLDIAMINE WAS INDICATED. IN VITRO STUDIES SHOWED THAT MOUSE LIVER MICROSOMES CONVERTED DICHLORAN TO THE AMINOPHENOL AND THE PHENYLENEDIAMINE. TLC SHOWED THAT THIS CONVERSION WAS SMALL. ABOUT 91% OF THE BOTRAN WAS RECOVERED UNCHANGED.
The in-vitro metabolism of 2,6-dichloro-4-nitroaniline was studied in efforts to characterize the isozymes of cytochrome-P-450 by which it is metabolized and to determine the origin of the oxygen in the phenol metabolite. Female Sprague-Dawley-rats were given 500 mg/kg or 1000 mg/kg of 2,6-dichloro-4-nitroaniline by gavage or 80 mg/kg phenobarbital (PB) intraperitoneally (ip) for 4 days. On day five the animals were injected with 35 mg/mg pentobarbital ip, and sleeping times were recorded. Liver microsomes were prepared from immature female Sprague-Dawley-rats treated with 75mg/kg PB, 40 mg/kg 3-methylcholanthrene (MC), or 1000 mg/kg 2,6-dichloro-4-nitroaniline. The parent compound appeared to induce its own metabolism. In-vitro microsomal aerobic production of 3,5-dichloro-p-aminophenol (DCAP) was increased 4 to 6.5 fold with respect to controls after treatment with 2,6-dichloro-4-nitroaniline. The addition of specific antibodies to cytochrome-P-450d inhibited the microsomal production of DCAP, indicating that the removal of the nitro group and subsequent replacement with a hydroxyl group was initiated by cytochrome-P-450d in the mixed function oxidase system. This hydroxyl group came from water and not molecular oxygen. The findings showed that cytochrome-P-450d was induced by 2,6-dichloro-4-nitroaniline and this cytochrome initiated the hepatic metabolism of 2,6-dichloro-4-nitroaniline to an N-hydroxylamine, followed by a non P-450 mediated attack of water causing the removal of nitrous-acid and the formation of the phenol.
RATS FED DICLORAN EXCRETE A TRACE OF THE UNCHANGED CMPD PLUS 3,5-DICHLORO-4-AMINOPHENOL & 2,6-DICHLORO-P-PHENYLENEDIAMINE. THIS APPARENTLY REPRESENTS 2 ROUTES OF METABOLISM, AS INTERCONVERSION OF THE 2 METABOLITES COULD NOT BE DEMONSTRATED. IN RATS GIVEN (14)C DICLORAN, 70% OF THE ACTIVITY IN THE FIRST 24 HR URINE REPRESENTED THE OTHER METABOLITE, & THE REMAINDER WAS IN THE FORM OF UNIDENTIFIED MATERIALS.
Oral metabolism studies in rats showed that dicloran is rapidly absorbed and metabolized ... The major urine metabolites were DCHA- sulfate and DCHA-glucuronide which accounted for 45.5% to 79% of the total dose. Other metabolites detected were DCHA (3.3 to 22.8%), DCAP (0.3% to 8.5%), and DCNAP (<0.1% to 1.0%).

Dicloran is well absorbed. ... Rats given (14)C-dicloran at rates of 5 or 10 mg/rat (about 20 or 40 mg/kg) excreted 70 & 77%, respectively, in the urine within 24 hr following intraperitoneal & oral intake; by 48 hr, the corresponding values were 80 & 90%. Only about 1% was excreted in feces, & this was less than 1/5 the amount excreted in the bile.
Oral metabolism studies in rats showed that dicloran is rapidly absorbed and metabolized in rats. Approximately 96 % of the administered dose was excreted in 24 hours. The urine was the major route of excretion (86.3% of the administered dose), and smaller amounts in feces (8.7% of the administered dose). Dicloran does not appear to accumulate in tissues. ... A small amount of dicloran was detected in feces.
In goats intubated with (14)C-dicloran, the administered radiolabel was completely recovered from urine and faeces by 72 hr; 38% was recovered within the first 24 hr from goats treated with 1.5 mg/kg bw and 96% from those given 8 mg/kg bw. More than 10 times more residues were found in goats than in Sprague-Dawley rats 72 hr after treatment, with only trace amounts of residues in other tissues. The liver residues in goats could not be extracted with organic solvents, whereas most of the radiolabelled residues were extractable from rat liver. In contrast, muscle residues from goats treated with a single dose of 8 mg/kg bw were not covalently bound to macromolecules. In a lactating goat given 613 mg (14)C-dicloran in a capsule daily for five days, 0.5% of the administered radiolabel was detected in milk. The parent compound and 4-amino-2,6-dichlorophenol were the major residues.
In groups of five hens dosed with (14)C-dicloran in capsules (0.37 or 6 mg/hen per day) for five days, dicloran was rapidly absorbed, metabolized, and eliminated. More than 80% was excreted, and 50-57% of the administered dose was recovered within 24 hr of dosing.
