The toxicity of the optical isomers S-(1,2-dichlorovinyl)-L-cysteine (L-DCVC) and S-(1,2-dichlorovinyl)-D-cysteine (D-DCVC) was investigated in vivo and in vitro. In vitro studies, utilizing a rabbit renal cortical slice system, demonstrated toxicity due to both forms with the L-form being more toxic. Dose- and time-dependent decreases in intracellular K+ and LDH were observed. Both compounds produced an initial S3 lesion, L-DCVC at 10-5 M (12 h), D-DCVC at 10-4 M (8 h), followed by a lesion encompassing all proximal tubules. In vivo studies demonstrated elevated blood urea nitrogen values at 24 and 48 h with 25 mg/kg of either isomer. Histopathology indicated both D and L-DCVC produced a straight proximal tubular lesion by 48 h, the lesion produced by L-DCVC being more severe. The D and L isomers of DCVC were both shown to be toxic, the toxicity assessed in vitro corresponded well with the toxicity in vivo.
