Cytochrome P450

Cytochrome P450 (CYP) inhibitors act on heme enzymes that oxidize drugs, steroids and other lipophilic compounds. The name comes from the 450 nm absorption peak of a carbon monoxide-bound pigment, described in liver microsomes in 1964. Hepatic enzymes such as CYP3A4, CYP2C9 and CYP1A2 metabolize a large share of drugs and many environmental chemicals. Other members synthesize steroid hormones, among them CYP17A1, which is required for androgen production. The P450 system can also convert chemicals into toxic or carcinogenic metabolites, which links it closely to toxicology. Abiraterone inhibits CYP17A1, while clarithromycin and itraconazole serve as CYP3A4 inhibitors in drug-interaction studies. Alizarin is listed for its inhibition of enzymes in the CYP1 family.

    Apigenin

    Synonyms: 4',5,7-Trihydroxyflavone; Apigenol; C.I. Natural Yellow 1

    Apigenin, found in many plants, is a natural product belonging to the flavone class that is the aglycone of several naturally-occurring glycosides. Apigenin acts as a monoamine transporter activator, one of the few chemicals demonstrated to possess this property. Apigenin is a ligand for central benzodiazepine receptors that competitively inhibited the binding of flunitrazepam with a Ki of 4μM, exerting anxiolytic and slight sedative effects.

    1,2,3,4,7,8-Hexachlorodibenzofuran

    Synonyms: 1,2,3,4,7,8-HxCDF

    1,2,3,4,7,8-Hexachlorodibenzofuran is a selective activator of the CYP1A1 and CYP1B1 enzymes. It induces the expression of these cytochrome P450 enzymes and aryl hydrocarbon receptor repressor (AhRR) in human peripheral blood lymphocytes. This compound also stimulates ethoxyresorufin-O-deethylase activity, achieving approximately 20% of the response observed with TCDD at a BMR20TCDD of 0.115-0.143 nM. Its ability to modulate these pathways makes it a valuable tool for studying biological responses to environmental pollutants and the mechanisms of xenobiotic metabolism.
