Cancer continues to be a significant public health issue and one of the leading causes of death globally. In this context, developing new, potent, and more specific treatments against this disease is urgent.
A total of 15 benzoxathiolone-thiazolidinones hybrids were synthesized in a 5-step route and tested for their cytotoxicity against five human cancer cell lines: AGP-01 (gastric), SKMEL-103 (melanoma), HCT-116 (colon), CAL27 (tongue), and K562 (leukemia), as well as a non-tumoral cell line MRC-5.
Compounds 3-(6-hydroxy-2-oxobenzo[d][1,3]oxathiol-5-yl)-2-(4-nitrophenyl)thiazolidin-4-one and 2-(2,4-dichlorophenyl)-3-(6-hydroxy-2-oxobenzo[d][1,3]oxathiol-5-yl)thiazolidin-4-one exhibited good activity against the K562 leukemia cell line, with IC50 values of 4.0 μM and 5.3 μM, respectively. Docking studies demonstrated that these compounds likely bind to the BCR-ABL1 kinase, a key protein in the pathogenesis of chronic myeloid leukemia (CML).
The study suggests these benzoxathiolone-thiazolidinone hybrids could be promising lead compounds for developing new anticancer agents targeting leukemia.
