2,3,4,6,7,8-Hexachlorodibenzofuran (2,3,4,6,7,8-HxCDF) is a type of polychlorinated dibenzofuran (PCDF). It induces the expression of aryl hydrocarbon hydroxylase (AHH) and ethoxyresorufin-o-deethylase (EROD) genes in H-4-II-E rat hepatoma cells, with EC50 values of 0.687 and 0.575 nM, respectively.

1,2,3,4,7,8,9-Heptachlorodibenzofuran (1,2,3,4,7,8,9-HpCDF) is a chemical compound known for inducing the expression of CYP1A1 and CYP1B1 genes in human peripheral blood lymphocytes, while also enhancing the expression of the aromatic hydrocarbon receptor repressor (AhRR). In isolated human peripheral blood lymphocytes, it boosts ethoxyresorufin-O-deethylase (EROD) activity—a marker for CYP1A1 activity—in a concentration-dependent manner. Additionally, 1,2,3,4,7,8,9-HpCDF exhibits immunosuppressive properties, reducing the number of plaque-forming cells in mouse spleens and increasing aromatic hydrocarbon hydroxylase (AHH) activity in the liver microsomes of mice injected with sheep red blood cells. This compound is pertinent to research in the fields of immunology, metabolic diseases, and environmental toxicology.

1,2,3,6,7,8-Hexachlorodibenzofuran (1,2,3,6,7,8-HxCDF) is a type of polychlorinated dibenzofuran (PCDF). It promotes the expression of aryl hydrocarbon hydroxylase (AHH) and ethoxyresorufin-O-deethylase (EROD) genes in H-4-II-E rat hepatoma cells with EC50 values of 1.47 and 1.24 nM, respectively. 1,2,3,6,7,8-HxCDF also reduces rat body weight, causes thymic atrophy, and induces the expression of cytochrome P450 (CYP) subtype CYP1A1 and 4-chlorobiphenyl hydroxylase genes with EC50 values of 3.2, 0.9, 0.35, and 0.21 µmol kg.

P53/TLR2 modulator-1 (Compound Z9) is an agent that targets both the P53 pathway and TLR2, exhibiting radioprotective properties. It mitigates apoptosis by inhibiting radiation-induced expression of P53 and Bax. Concurrently, it enhances the TLR2 pathway by upregulating downstream proteins MyD88 and P65, which promotes secretion of cytokines like IL-6, providing radioprotective effects. P53/TLR2 modulator-1 shows significant radioprotective activity in AHH-1 and HUVECs cells, enhances survival rates in C57BL/6J mice exposed to lethal radiation doses, and alleviates radiation-induced damage to their hematopoietic system, intestinal villi, and spleen. It is applicable for research on radiation-related diseases.

Tetrahydropiperine (Cosmoperine) is a natural product derived from piperine, can be used to treat convulsion, epilepsy, relieve pain, and control insects.
