Because of the threat of resistant Plasmodium sp., new orally active antimalarials are urgently needed. Inspired by the structure of ellagic acid, exhibiting potent in vivo and in vitro antiplasmodial effects, polyphenolic structures possessing a similar activity-safety profile were synthesized. Indeed, most exhibited a marked in vitro effect (IC50 < 4 μM) on resistant P. falciparum, without any detrimental
由于耐药疟原虫的威胁。 ,迫切需要新的口服活性抗疟药。受鞣花酸结构的启发,在体内和体外表现出有效的抗疟原虫作用,合成了具有相似活性-安全性的多酚结构。事实上,大多数药物对恶性疟原虫具有显着的体外作用(IC 50 < 4 μM),而在毒性测定(溶血、细胞毒性、体内)期间没有报告任何有害作用。此外,与鞣花酸相比,它们具有更高的水溶性(从 7 μM 到 2.7 mM)。其中, 30是最有希望用于抗疟用途的,因为与口服无效的鞣花酸相比,其在小鼠口服给药(50 mg kg -1 )后显示出显着的寄生虫血症减少。总之,我们的研究发现了一种有前途的支架,这可以为疟疾治疗带来新的见解。
