In vitro genotoxic and antigenotoxic effects of ten novel synthesized 4-thiazolidinone derivatives.

Heterocyclic compounds are found in a variety of drug molecules, and bioactive natural products. 4-Thiazolidinones (4-TZDs), which represent an important class of heterocyclic compounds, are of great interest today with their diverse bioactivities. In this study, ten novel 4-TZD derivatives (C1-C10) were synthesized, characterized by spectroscopic techniques, and their genotoxic, and antigenotoxic properties were investigated in vitro using the Ames Salmonella/microsome mutagenicity assay in the concentration range of 0.2-1.0 mM/plate. The results revealed that none of the compounds were mutagenic on the three different Salmonella typhimurium strains up to the highest concentration tested. Furthermore, in our study, C1, C4, C6, and C9 showed significant, ranging from moderate to strong, antigenotoxic effects against mutagen-induced DNA damage at relatively higher doses. Among these, C4 had the best potential to inhibit the number of revertant colonies induced by 9-aminoacridine (9-AA), with a maximum inhibition rate of 47.9% for 1.0 mM/plate. As a result, preliminary knowledge about the safety of the use of ten novel synthesized 4-TZD compounds likely to exhibit many bioactivities was obtained in this study. In addition, the significant in vitro antimutagenic activity of some derivatives increases the importance of studies for the development of new pharmacological agents for cancer prevention.
