The design, synthesis, and biological evaluation of 18 ferrocenylderivatives (4A–12A and 4B–12B) of the most well-known drug against schistosomiasis, namely praziquantel (PZQ), are reported. These compounds, which have been all isolated as racemates, were unambiguously characterized by 1H and 13C NMR spectroscopy, mass spectrometry, and elemental analysis as well as by X-ray crystallography for 4A
据报道,最著名的抗血吸虫病药物吡喹酮(PZQ)的18种二茂铁基衍生物(4A – 12A和4B – 12B)的设计,合成和生物学评估。这些化合物均已作为外消旋物分离,并通过1 H和13 C NMR光谱,质谱和元素分析以及X射线晶体学对4A,5A和7A进行了明确鉴定。。细胞毒性研究表明,该复合物对宫颈癌细胞系(HeLa)具有中等毒性,并且重要的是,对非癌细胞系(MRC-5)的活性明显较低。在体外的18二茂铁衍生物PZQ的驱虫活性对成人测试曼氏血吸虫,并测定对四种最活性的化合物在微摩尔范围(26-68μM)值。还证明了使用该系列的两种化合物作为模型(8A和8B),当在人血浆中于37°C孵育24小时时,复合物是稳定的。
