Nephrotoxicity of the agricultural fungicide N-(3,5-dichlorophenyl)succinimide (NDPS) in rats is believed to involve metabolism on the succinimide ring. To further investigate this hypothesis, we synthesized and tested the following NDPS analogues, which contain other cyclic imide rings and may therefore be metabolized differently than NDPS: 3-(3,5-dichlorophenyl)-2,4-oxazolidinedione (DCPO), 3-(3
人们认为,农用杀菌剂N-(3,5-二氯苯基)琥珀酰亚胺(NDPS)对大鼠的肾毒性涉及琥珀酰亚胺环上的代谢。为了进一步研究该假设,我们合成并测试了以下NDPS类似物,其包含其他环状酰亚胺环,因此可能与NDPS代谢不同:3-(3,5-二氯苯基)-2,4-恶唑烷二酮(DCPO),3 -(3,5-二氯苯基)-2,4-咪唑烷二酮(DCPI),3-(3,5-二氯苯基)-1-甲基-2,4-咪唑烷二酮(DCPM)和3-(3,5-二氯苯基) -2,4-噻唑烷二酮(DCPT)。雄性Fischer 344大鼠接受DCPO,DCPI,DCPM,DCPT(0.6或1.0 mmol / kg,ip在玉米油中),NDPS(0.6 mmol / kg,ip在玉米油中)或玉米油(4 ml / kg)。如利尿,蛋白尿,血尿素氮水平升高,肾脏重量增加和近端肾小管损伤,NDPS对大鼠产生严重的肾毒性。相反,DCPO,DCPI,D
