Summary
Aqueous mistletoe extract (AME) showed no genotoxic potential in vitro. Comprehensive studies, including gene mutation and cytogenetic assays, confirmed its safety profile, indicating no harmful effects on genetic material.
Area of Science:
- Pharmacology and Toxicology
- Molecular Biology
- In Vitro Assays
Background:
- Mistletoe extracts are used in complementary medicine.
- Assessing the genotoxic potential of pharmaceutical compounds is crucial for safety.
- Lektinol contains an aqueous mistletoe extract (AME) as its active principle.
Purpose of the Study:
- To evaluate the genotoxic potential of aqueous mistletoe extract (AME).
- To adhere to international guidelines for in vitro genotoxicity testing.
Main Methods:
- Bacterial reverse mutation assay (Ames test).
- In vitro mammalian cell gene mutation tests.
- In vitro cytogenetic studies on human lymphocytes.
- Syrian hamster embryo cell transformation assay.
Main Results:
- All gene mutation tests (bacterial and mammalian) yielded negative results.
- Cytogenetic studies showed no evidence of clastogenic activity in human lymphocytes.
- The cell transformation assay did not reveal any malignant changes in cell cultures.
Conclusions:
- The aqueous mistletoe extract (AME) demonstrated no genotoxic potential in the comprehensive in vitro testing conducted.
- The findings suggest that AME is safe regarding genotoxicity based on current in vitro evidence.
