Herein, we report the synthesis and evaluation of pyrvinium-based antimalarial and antitubercular compounds. Pyrvinium is an FDA approved drug for the treatment of pinworm infection, and it has been reported to have antiparasitic and antimicrobial activities. Pyrvinium contains quinoline core coupled with pyrrole. We replaced the pyrrole with various aryl or heteroaryl substituents to generate pyrvinium
在此,我们报告了基于吡虫铵的抗疟和抗结核化合物的合成和评估。Pyrvinium是FDA批准的用于治疗pin虫感染的药物,据报道它具有抗寄生虫和抗菌活性。吡啶含喹啉核与吡咯。我们用各种芳基或杂芳基取代基取代了吡咯,生成了吡喃鎓类似物。这些化合物针对疟原虫恶性疟原虫3D7的概况分析显示,其类似物具有比丙酮酸丙酮酸丙酮酯更好的抗疟活性。化合物14和16对恶性疟原虫3D7的IC50分别为23 nM和60 nM。这些化合物还有效抵抗耐药疟原虫恶性疟原虫Dd2,IC50分别为53 nM和97 nM。对CHO-K1的细胞毒性 与pyrvinium相比,HEK和NRK-49F细胞对这些新类似物的选择性指数更高。另外,该系列化合物显示出抗结核分枝杆菌H37Rv的活性。特别地,化合物10、13、14和16显示出与棕榈酸丙酮酸同等的抗结核活性。化合物14和16应该作为进一步优化的线索。
