    Abstract:
    Previous studies have demonstrated that N-(3,5-dichlorophenyl)succinimide (NDCPS) is the most nephrotoxic compound among the N-(mono- or dichlorophenyl)succinimides. The purpose of this study was to examine the nephrotoxic potential of the different N-(3,5-dihalophenyl)succinimides (NDHPS) to determine the importance of the halogen species for NDHPS-induced nephrotoxicity. Male Fischer 344 rats were administered a single intraperitoneal injection of an NDHPS (0.4, 0.8, or 1.0 mmol/kg) or vehicle (2.5 ml/kg), and renal function was monitored at 24 and 48 h. NDCPS or N-(3,5-diiodophenyl)succinimide administration produced the greatest nephrotoxic response. Nephrotoxicity was characterized by diuresis, increased proteinuria, glucosuria, increased kidney weight and blood urea nitrogen (BUN) concentration, decreased accumulation of p-aminohippurate (PAH) and tetraethylammonium (TEA) by renal cortical slices and proximal tubular necrosis. N-(3,5-Dibromophenyl)succinimide injection produced mild nephrotoxicity, while N-(3,5,-difluorophenyl)succinimide administration did not result in nephrotoxicity. These results indicate that the halogen species can influence the nephrotoxicity produced by the NDHPS. In addition, nephrotoxic potential did not correlate with fungicidal efficacy, which suggests that the nephrotoxic and fungicidal mechanisms of these compounds might be different.
