Griseofulvin did not induce chromosomal damage in mice or mutations in bacteria. Control tests with thio-TEPA confirmed the assay

Area of Science:

Toxicology
Genetics
Microbiology

Background:

Griseofulvin is an antifungal medication.
Assessing the genotoxicity of pharmaceutical compounds is crucial for public health and safety.

Purpose of the Study:

To evaluate the potential of griseofulvin to cause genotoxicity.
To investigate its capacity for inducing chromosomal aberrations and bacterial mutations.

Main Methods:

Assessing structural chromosomal aberrations in germ and somatic cells of male mice.
Testing for his+ revertants in Salmonella typhimurium using the Ames test.
Utilizing thio-TEPA as a positive control for genotoxicity.

Main Results:

Griseofulvin did not induce significant structural chromosomal aberrations in mouse cells.

Griseofulvin did not produce his+ revertants in Salmonella typhimurium.

Positive control thio-TEPA demonstrated significant genotoxic effects, validating the assays.

Conclusions:

Griseofulvin exhibits no genotoxic potential in the conducted in vivo and in vitro assays.
The study provides evidence for the safety of griseofulvin concerning genotoxicity.
The experimental setup was validated by the positive control, ensuring reliable results.
