Perfluorooctane sulfonamide (FOSA) is known as a key intermediate of perfluorooctane sulfonic acid (PFOS) precursors, which can be frequently delected in the environment and biota. FOSA could be bioaccumulated in earthworms from soil, but the contributions of enzymes and gut microbes involved in the biotransformation of FOSA in earthworms have not been identified. Therefore, the elects of enzyme inhibitors and intestinal microflora on biotransformation of FOSA in earthworms were investigated in the present study. FOSA was biotransformed to form PFOS by earthworms obtained from in vivo and in vitro tests. The addition of FOSA had significantly pos. elects on cytolchrome P 450 (CYP450) and glutathione-s-transferase (GST) activities, suggesting CYP450 and GST are likely involved in the enzymic transformation. In addition, both 1-Aminobenzotriazole (ABT) and ezatiostat hydrochloride (TLK199), which were selected to inhibit the CYP and GST enzymes, resp., demonstrated inhibition elects on biotransformation of FOSA in earthworms with a dose-dependent relationship. However, the concentrations of FOSA weren’t changed by the bacteria isolated from worm gut, suggesting that gut bacteria did not contribute to FOSA biotransformation in earthworms. The results of this study confirm that the transformation of FOSA in earthworms is mediated mainly by enzymes rather than by gut microbes. In the experiment, the researchers used many compounds, for example, 1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6COA of Formula: C6H6N4).
1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6) belongs to triazole derivatives. Many triazoles are versatile, biologically active compounds commonly used as fungicides and plant retardants. The presence of the three nitrogen atoms in triazole structures afforded opportunities for a plethora of structural modification with the generation of novel therapeutically potential agents, which is different from other heterocyclic compounds.COA of Formula: C6H6N4
