Eight novel analogues of Nifurtimox, 4-[(5-nitrofurfurylidene)amino]-3-methylthiomorpholine-1,1-dioxide, containing alpha-beta unsaturated amides, were synthesized and evaluated for their in vitro activity against Trypanosoma cruzi epimastigotes. Four derivatives bearing a nitro group at the 5-position of the furan ring were the most active in inhibiting culture growth and provoking cell death, showing
合成了八种新型的呋喃酮氮类似物,即4-[((5-硝基糠基亚氨基)氨基] -3-甲基硫代吗啉-1,1-二氧化物,含有α-β不饱和酰胺,并评估了它们对克鲁斯锥虫的体外活性。在呋喃环5位上带有硝基的四种衍生物在抑制培养物生长和引起细胞死亡方面最活跃,其锥虫杀伤活性超过了我们的阳性对照Nifurtimox的效力的三倍。缺少硝基的两种衍生物的效力低于阳性对照。活性硝基衍生物非常有效地导致淫前鞭毛虫死亡,这表明硝基还原的作用机理。
