Background Looking at the extensive biological potential of thiazolidine-2,4-dione (TZD) moiety, a new series of thiazolidine-2,4-dione analogues was synthesized. Different spectral techniques (1H-NMR, IR, MS etc.) were used to confirm the chemical structures of the synthesized analogues. These synthesized compounds were screened for their antioxidant and antimicrobial potential. Results and discussion The antimicrobial screening was carried out against selected strains of fungi and bacteria using serial tube dilution method. The antioxidant potential was assessed using stable 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method. Further, the interaction between synthesized thiazolidine-2,4-dione compounds and DNA gyrase was explored using molecular docking studies. Various ADME parameters were also studied to evaluate the drug likeness of the synthesized compounds. Conclusion In antimicrobial evaluation, the compounds 4, 9, 11, 12, 13, 15 and 16 displayed promising activity against selected strains of microbes. Antioxidant evaluation found compound 6 having IC50 = 9.18 μg/mL to be the most potent compound in the series. The molecular docking study revealed compounds 4 (dock score = - 4.73) and 7 (dock score = - 4.61) with decent docking score, possess good interaction inside the ATP binding pocket of DNA gyrase and therefore can be used as lead structure for further optimizing into potent antimicrobial molecule.

背景 鉴于 thiazolidine-2,4-dione (TZD) 部分的广泛生物学潜力,合成了一系列新的 thiazolidine-2,4-dione 类似物。不同的光谱技术(1H-NMR、IR、MS 等)用于确认合成类似物的化学结构。筛选这些合成的化合物的抗氧化和抗菌潜力。结果与讨论 使用连续试管稀释法对选定的真菌和细菌菌株进行抗菌筛选。使用稳定的 2,2-diphenyl-1-picrylhydrazyl (DPPH) 自由基清除方法评估抗氧化潜力。此外,使用分子对接研究探索了合成的 thiazolidine-2,4-dione 化合物与 DNA 促旋酶之间的相互作用。还研究了各种 ADME 参数以评估合成化合物的药物相似性。结论 在抗菌评估中,化合物 4、9、11、12、13、15 和 16 对选定的微生物菌株表现出有希望的活性。抗氧化剂评估发现,IC50 = 9.18 μg/mL 的化合物 6 是该系列中最有效的化合物。分子对接研究表明,化合物 4(dock score = - 4.73)和化合物 7(dock score = - 4.61)具有良好的对接得分,在 DNA 促旋酶的 ATP 结合口袋内具有良好的相互作用,因此可作为先导结构进一步优化成有效的抗菌分子。抗氧化剂评估发现,IC50 = 9.18 μg/mL 的化合物 6 是该系列中最有效的化合物。分子对接研究表明,化合物 4(dock score = - 4.73)和化合物 7(dock score = - 4.61)具有良好的对接得分,在 DNA 促旋酶的 ATP 结合口袋内具有良好的相互作用,因此可作为先导结构进一步优化成有效的抗菌分子。抗氧化剂评估发现,IC50 = 9.18 μg/mL 的化合物 6 是该系列中最有效的化合物。分子对接研究表明,化合物4(dock score = - 4.73)和化合物7(dock score = - 4.61)具有良好的对接得分,在DNA旋转酶的ATP结合口袋内具有良好的相互作用,因此可以作为进一步优化的先导结构成有效的抗菌分子。
