Human African Trypanosomiasis, also known as African sleeping sickness, is caused by the parasitic protozoa of the genus Trypanosoma. If there is no pharmacological intervention, the parasites can cross the blood-brain barrier (BBB), inevitably leading to death of the patients. Previous investigation identified the quinolone amide GHQ168 as a promising lead compound having a nanomolar activity against
人类非洲锥虫病,也称为非洲昏睡病,是由锥虫属的寄生原生动物引起的。如果没有药理学干预,这些寄生虫会穿过血脑屏障(BBB),不可避免地导致患者死亡。先前的研究确定喹诺酮酰胺GHQ168是一种有前途的对T. b具有纳摩尔活性的先导化合物。布鲁西。在这里,关于毒性,药代动力学和抗胰锥虫活性,研究了氟取代在不同位置的作用。这种“氟走”导致了新化合物具有更好的代谢稳定性和对T的一致活性。布鲁西。
