The metabolism of the anticoccidial 2-[3-chloro-4-(4-chlorobenzoyl)phenyl]-as-triazine-3,-5(2H,4H)-dione (CP-25,415) was investigated in the chicken. It was shown that the predominant residue present in the chicken was 2-[3-chloro-4-(alpha-hydroxy-4-chlorobenzoyl)phenyl]-as-triazine-3,5(2H,4H)-dione (CP-25,641). A gas-liquid chromatographic assay for the analysis of CP-25,641 in biological fluids and tissues was developed which was rapid, accurate, and reproducible. Results of the analytical method correlated well with radiochemical measurements and were indicative of the total drug-related residues. The half-life of CP-25,641 in tissues was approximately 32 hr except in the kidney, where the half-life was approximately 40 hr due to urine retention by the kidneys. CP-25,641 was excreted without further change. |
