In the pursuance of novel scaffolds with promising antiplasmodial and anti-inflammatory activity, a series of twenty-one compounds embraced with most promising penta-substituted pyrrole and biodynamic hydroxybutenolide in single skeleton was designed and synthesized. These pyrrole-hydroxybutenolide hybrids were evaluated against Plasmodium falciparum parasite. Four hybrids 5b, 5d, 5t and 5u exhibited
在追求具有有前途的抗疟原虫和抗炎活性的新型支架的过程中,设计并合成了一系列包含最有前途的五取代吡咯和生物动力学羟基丁烯内酯的单一骨架的 21 种化合物。这些吡咯-羟基丁烯内酯杂化物针对恶性疟原虫寄生虫进行了评估。四种杂交体5b、 5d、 5t和5u表现出良好的活性,对于氯喹敏感( Pf 3D7)菌株,IC 50为 0.60、0.88、0.97 和 0.96 μM,对于氯喹抗性( Pf K1)菌株,IC 50 为 3.92、4.31、4.21 和 1.67 μM分别。体内研究了5b、5d、5t和5u对瑞士小鼠P. yoelii nigeriensis N67(一种抗氯喹)寄生虫的疗效,剂量为 100 mg/kg/天,持续 4 天,口服途径。发现5u显示最大 100% 的寄生虫抑制,平均存活时间显着增加。同时,筛选了一系列化合物的抗炎潜力。在初步测定中,9 种化合物对 LPS 刺激的 THP-1
