Abstract:
The fate of xenobiotics in the organism and their toxic or therapeutic influence have been under intensive investigation in recent years. The compounds are searched for which affect as preventive agents cancerogenesis and other disorders caused by procancerogens and pro-mutagens from the environment. The main focus is on the compounds able to modulate the activity of enzymes of the Ist and IInd phase of xenobiotic detoxication or compounds with antioxidative activity. In the following review, compounds of natural origin are presented which possess an ability to modulate the processes connected with detoxication of xenobiotics. These compounds could be usable as preventive agents against some diseases or as supportive pharmaceuticals during chemotherapy.
Insights
Natural compounds can prevent cancer and support chemotherapy by modulating xenobiotic detoxification enzymes and antioxidant activity. These agents offer potential in combating environmental carcinogens and mutagens.
Area of Science:
- Pharmacology and Toxicology
- Environmental Health
- Natural Product Chemistry
Context:
- Investigating xenobiotic metabolism and its role in disease development.
- Identifying environmental factors (procancerogens, pro-mutagens) contributing to health disorders.
- Focus on compounds influencing xenobiotic detoxification pathways and antioxidant defense.
Purpose:
- To review natural compounds that modulate xenobiotic detoxification.
- To explore the potential of these compounds as preventive agents against diseases.
- To assess their utility as supportive therapies in chemotherapy.
Summary:
- This review highlights natural compounds with the ability to modulate Phase I and Phase II xenobiotic detoxification enzymes.
- It discusses compounds possessing antioxidant properties that can counteract environmental toxins.
- Natural products are presented for their potential to prevent diseases linked to xenobiotic exposure and aid cancer treatment.
Impact:
- Provides insights into natural preventive agents against cancer and other disorders.
- Suggests natural compounds as supportive pharmaceuticals in chemotherapy.
- Offers a basis for developing novel therapeutic strategies targeting xenobiotic metabolism.

Antidotes
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...
