Abstract:
The naturally occurring flavouring agents trans-anethole and eugenol were evaluated for antigenotoxic effects in mice. The test doses of trans-anethole (40-400 mg/kg body weight) and eugenol (50-500 mg/kg weight) were administered by gavage 2 and 20 h before the genotoxins were injected intraperitoneally. Anti-genotoxic effects were assessed in the mouse bone marrow micronucleus test. Pretreatment with trans-anethole and eugenol led to significant antigenotoxic effects against cyclophosphamide (CPH), procarbazine (PCB), N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and urethane (URE). In addition, trans-anethole inhibited the genotoxicity of ethyl methane sulfonate (EMS). Both trans-anethole and eugenol exerted dose-related antigenotoxic effects against PCB and URE. There was no significant increase in genotoxicity when trans-anethole (40-400 mg/kg body weight) and eugenol (50-500 mg/kg body weight) were administered alone.
Insights
Naturally occurring compounds trans-anethole and eugenol show significant antigenotoxic effects in mice. These flavouring agents protect against genotoxicity without causing harm themselves, suggesting potential protective roles.
Area of Science:
- Pharmacology
- Toxicology
- Natural Products Chemistry
Background:
- Trans-anethole and eugenol are naturally occurring flavouring agents.
- Genotoxicity is a major concern in toxicology and drug development.
- Assessing antigenotoxic effects of natural compounds is crucial for understanding their safety and potential therapeutic benefits.
Purpose of the Study:
- To evaluate the antigenotoxic effects of trans-anethole and eugenol in a mouse model.
- To determine if these compounds can protect against chemically induced genotoxicity.
- To assess the dose-response relationship and safety of trans-anethole and eugenol pretreatment.
Main Methods:
- Mice were pretreated with varying doses of trans-anethole (40-400 mg/kg) and eugenol (50-500 mg/kg) via gavage.
- Genotoxicity was induced by intraperitoneal injection of agents like cyclophosphamide (CPH), procarbazine (PCB), N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), urethane (URE), and ethyl methane sulfonate (EMS).
- Antigenotoxic effects were evaluated using the mouse bone marrow micronucleus test.
Main Results:
- Both trans-anethole and eugenol demonstrated significant antigenotoxic effects against CPH, PCB, MNNG, and URE.
- Trans-anethole also inhibited the genotoxicity induced by ethyl methane sulfonate (EMS).
- Dose-dependent antigenotoxic activity was observed for both compounds against PCB and URE, with no observed genotoxicity when administered alone.
Conclusions:
- Trans-anethole and eugenol possess significant antigenotoxic properties in vivo.
- These natural flavouring agents can protect against a range of genotoxic insults.
- The findings support the potential use of trans-anethole and eugenol as protective agents against genotoxicity.
