    Thiophene is a heterocyclic compound with the formula C 4 H 4 S. Consisting of a planar five-membered ring, it is aromatic as indicated by its extensive substitution reactions. ...

  8. Heterocyclic compound - Wikipedia

    en.wikipedia.org/wiki/Heterocyclic_compound

    The fusion of two benzene rings gives rise to a third large family of organic compounds. Analogs of the previously mentioned heterocycles for this third family of compounds are acridine, dibenzothiophene, carbazole, and dibenzofuran, respectively. Heterocyclic organic compounds can be usefully classified based on their electronic structure.

    TCDD and dioxin-like compounds act via a specific receptor present in all cells: the aryl hydrocarbon (AH) receptor. [6] [7] [8] This receptor is a transcription factor which is involved in the expression of genes; it has been shown that high doses of TCDD either increase or decrease the expression of several hundred genes in rats.
