プロジェクト背景 ニトロイミダゾールは、嫌気性細菌やトリコモナス原虫に効果的に作用する合成抗菌薬および抗原虫薬です。かつては家畜や養殖業で消化器感染症や原虫病の制御に広く使用され、生存率を向上させていました。しかし、親薬物とその代謝物は明らかに毒性があります。動物体内ではいくつかの活性代謝物に急速に代謝され、その一部は親化合物よりもはるかに長く組織中に残留します。 毒性学的研究によると、ニトロイミダゾール親薬物とその主要代謝物は、発がん性、変異原性、遺伝毒性の可能性があります。動物由来食品中の残留物は、食物連鎖を通じて人体に取り込まれ、長期間の低用量摂取は造血作用を妨げ、染色体を損傷し、遺伝子...
