In this study, seven new 4-oxothiazolidine derivatives were synthesized and tested for inhibitory properties against DNase I and XO, with one compound showing dual inhibitory activity. The most potent DNase I inhibitor reported so far was observed among the tested compounds. The study also involved molecular docking and dynamics simulations to clarify the binding modes of the derivative for potential future development of dual DNase I and XO inhibitors.
In this study, seven new 4-oxothiazolidine derivatives were synthesized and assayed, along 7 known derivatives, for inhibitory properties against deoxyribonuclease I (DNase I) and xanthine oxidase (XO) in vitro. Among tested compounds, (5Z)-Ethyl-2-(2-(cyanomethylene)-4-oxothiazolidin-5-yliden)acetate (6) exhibited inhibitory activity against both enzymes (DNase I IC50 = 67.94 +/- 5.99 mu M; XO IC50 = 98.98 +/- 13.47 mu M), therefore being the first reported dual inhibitor of DNase I and XO. Observed DNase I inhibition qualifies compound 6 as the most potent small organic DNase I inhibitor reported so far. Derivatives of 2-alkyliden-4-oxothiazolidinone (1) inhibited DNase I below 200 mu M, while the other tested 4-oxothiazolidine derivatives remained inactive against both enzymes. The molecular docking and molecular dynamics simulations into the binding sites of DNase I and XO enzyme allowed us to clarify the binding modes of this 4-oxothiazolidine derivative, which might aid future development of dual DNase I and XO.
