Fifteen new heterocyclic thiazolidinones have been synthesized from one-pot reactions of piperonylamine, arenealdehydes and mercaptoacetic acid. These compounds plus ten 2-aryl-3-(benzyl)-1,3-thiazolidin-4-ones which had been previously synthesized, were evaluated as antibacterial agents against Mycobacterium tuberculosis H37Rv using the Alamar Blue susceptibility test and their activity expressed as the minimum inhibitory concentration (MIC) in μg/mL. Six of the series exhibited modest activity when compared to the first line drugs such as isoniazid (INH) and rifampicin (RIP). Therefore this class of compounds could be a good starting point to develop new lead compounds in the treatment of multi-drug resistant tuberculosis.
通过哌丙基胺、异醛和巯基乙酸的一锅反应,合成了 15 个新的杂环噻唑烷酮。采用阿拉玛蓝药敏试验,将这些化合物和以前合成的 10 个 2-芳基-3-(苄基)-1,3-噻唑烷-4-酮作为抗结核分枝杆菌 H37Rv 的抗菌剂进行了评估,其活性以最小抑菌浓度(MIC)表示,单位为 μg/mL。与异烟肼(INH)和利福平(RIP)等一线药物相比,六种系列化合物表现出适度的活性。因此,这类化合物可能是开发治疗耐多药结核病新先导化合物的良好起点。
