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.
Heterocyclic compounds are of particular importance among pharmacologically active compounds. In this study, some piperonyl‐based 4‐thiazolidinone derivatives (2a–i) were synthesized and characterized by spectroscopic assays. All molecules were tested as enzyme inhibitory factors. These compounds were effective inhibitors of the enzymes acetylcholinesterase (AChE), α‐glycosidase (α‐Gly), and the human
杂环化合物在药理活性化合物中特别重要。在这项研究中,合成了一些基于胡椒基的 4-噻唑烷酮衍生物 (2a-i),并通过光谱分析对其进行了表征。所有分子均作为酶抑制因子进行测试。这些化合物是乙酰胆碱酯酶 (AChE)、α-糖苷酶 (α-Gly) 和人碳酸酐酶 I 和 II 异构体(hCA I 和 II)的有效抑制剂,Ki 值范围为 8.90-66.51 nM。 α-Gly,hCA I 为 94.8–289.5 nM,hCA II 为 106.3–304.6 nM,AChE 为 0.55–2.36 nM。还对合成的分子进行了理论研究。进行分子对接计算以研究目标蛋白质和分子之间的相互作用。CA 抑制剂化合物作为抗青光眼和利尿剂在临床上已使用了近 60 年。AChE 酶的抑制导致 ACh 水解的阻断。相反,AChE 抑制剂化合物或/和调节剂的设计引起了人们的极大兴趣,因为它是预防阿尔茨海默病最流行的工具之一。
