AIM: To evaluate the cytotoxic action of 4-thiazolidinone derivatives (ID 3288, ID 3882, and ID 3833) toward rat glioma C6 cells and to compare the effects of these compounds and doxorubicin on the balance of free radical oxidation (FRO) and antioxidant activity (AOA) in the serum of rats.
METHODS: Glioma cells were treated with ID 3882, ID 3288, ID 3833, and doxorubicin, and their cytotoxicity was studied using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and Trypan blue exclusion test, light and fluorescent microscopy, and flow cytometric study of cell cycling and apoptosis, including measuring of Annexin V-positive cells. The contents of superoxide radical, hydrogen peroxide, hydroxyl radical, malonic dialdehyde, and hydrogen sulfide were measured in the serum of rats. Enzymatic activity of superoxide dismutase (SOD), catalase (Cat), and glutathione peroxydase (GPO) was determined.
RESULTS: Among novel 4-thiazolidinone derivatives, ID 3288 was most toxic toward rat glioma C6 cells, even compared with doxorubicin. All applied derivatives were less active than doxorubicin in inducing reactive oxygen species-related indicators in the serum of rats. A similar effect was observed when enzymatic indicators of AOA processes were measured. While doxorubicin inhibited the activity of SOD, GPO, and Cat, the effects of 4-thiazolidinone derivatives were less prominent.
CONCLUSION: Novel 4-thiazolidinone derivatives differ in their antineoplastic action toward rat glioma C6 cells, and ID 3288 possesses the highest activity compared to doxorubicin. Measurement of indicators of FRO and AOA in the serum of rats treated with these compounds showed their lower general toxicity compared with doxorubicin's toxicity.
