Novel series of bis- and tris-pyrrolo[1,2-a]quinoxaline derivatives 1 were synthesized and tested for in vitro activity upon the intraerythrocytic stage of W2 and 3D7 Plasmodium falciparum strains. Biological results showed good antimalarial activity with IC50 in the μM range. In attempting to investigate the large broad-spectrum antiprotozoal activities of these new derivatives, their properties toward
合成了新型的双-和三-吡咯并[1,2-a]喹喔啉衍生物1,并测试了W2和3D7恶性疟原虫菌株在红细胞生成阶段的体外活性。生物学结果显示良好的抗疟活性,IC50在μM范围内。为了研究这些新衍生物的广谱抗原生动物活性,还研究了它们对利什曼原虫的特性,并揭示了它们的选择性抗疟原虫特性。同时,在人HepG2细胞系上评估了这些分子的体外细胞毒性。这些新的合成化合物的构效关系在这里讨论。双吡咯并[1,2-a]喹喔啉1n和1p被确定为最有效的抗疟候选物,对W2菌株的选择性指数(SI)为40.6,为39。25对3D7株。由于寄生虫的端粒可能构成诱人的靶标,因此我们研究了通过新化合物通过FRET熔解法稳定疟原虫端粒G-四链体来靶向疟原虫端粒的可能性。
