Trichlorocarban (TCC) is ubiquitously detected in environmental matrixes, while there is a paucity of information regarding its systemic toxicity. In the present study, we observed that TCC exposure led to high embryo mortality, delayed hatching and yolk absorption, as well as increased malformations, such as closure of swim sac and yolk sac edema. Meanwhile, TCC affected the formation and branch of subintestinal veins (SIVs), intersegmental vessels and posterior cardinal veins. Especially, the SIVs were shrunk, and their branches were reduced or even broken along with reduced coverage area. TCC-induced oxidative stress and excessive apoptosis resulted from abnormal expression of the anti/pro-apoptotic genes. Significant reduction in the number and aggregation function of immune cells proved that TCC had prominent immunotoxicity to zebrafish. TCC-targeted TLR4 signaling pathway was demonstrated by abnormal expression of the marker genes (tlr4, MyD88 and nf-魏b) and release of the downstream inflammatory factors (TNF-伪, IL-6, etc.). Inhibition of TLR4/MyD88/NF-魏B pathway by an inhibitor (CA-4948) rescued the decreasing trend of the immune cells induced by TCC. Mol. docking results demonstrated that TCC could stably bind to TLR4 receptor to form hydrogen bonds and hydrophobic interactions with amino acids. Overall, these findings reveal the underlying mol. mechanisms on TCC-induced developmental and immune toxicity to zebrafish. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Recommanded Product: 101-20-2).
1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Recommanded Product: 101-20-2
