Aims & Objective: In this work, the multicomponent reaction of aldehydes, benzoylisothiocyanate and alkyl bromides in the presence of ammonium acetate, sodium cyanide and a catalytic amount of KF/Clinoptilolite nanoparticles (KF/CP NPs) in the water at 100oC was investigated.

Materials and Methods: In these reactions, thiazole derivatives were produced in good to excellent yields and short time. Also, the antioxidant activity was studied for some newly synthesized compounds using the DPPH radical trapping and reducing of ferric ion experiments and comparing results with the synthetic antioxidants (TBHQ and BHT).

Results: As a result, the compounds 4b showed excellent DPPH radical trapping and reducing the strength of ferric ion. These compounds have biological potential because of the thiazole core. For this reason, the antimicrobial activity of some synthesized compounds was studied by employing the disk diffusion test on Gram-positive bacteria and Gram-negative bacteria.

Conclusion: The results of the disk diffusion test showed that these compounds prevented bacterial growth.

目的与目的：在这项工作中，研究了醛、苯甲酰异硫氰酸酯和烷基溴在乙酸铵、氰化钠和催化量的 KF/斜发沸石纳米颗粒（KF/CP NPs）存在下在 100oC 水中的多组分反应。

材料和方法：在这些反应中，噻唑衍生物以良好到极好的收率和较短的时间生产。此外，还使用 ​​DPPH 自由基捕获和还原铁离子实验研究了一些新合成化合物的抗氧化活性，并将结果与​​合成抗氧化剂（TBHQ 和 BHT）进行了比较。

结果：结果，化合物4b表现出优异的DPPH自由基捕获和降低铁离子强度。由于噻唑核，这些化合物具有生物学潜力。为此，一些合成化合物的抗菌活性通过对革兰氏阳性菌和革兰氏阴性菌采用圆盘扩散试验来研究。

结论：圆盘扩散试验的结果表明这些化合物可防止细菌生长。
