A series of thieno[2,3-b]quinolone derivatives were synthesized and investigated for their abilities to inhibit β-hematin formation, hemoglobin hydrolysis and in vivo for their efficacy in rodent Plasmodium berghei. Compound 3b was the most promising as inhibitor of hemoglobin hydrolysis, and its effects as inhibitor of β-hematin formation was promising. When the aromatic ring was substituted in 2
一系列的噻吩并[ 2,3- b ]喹诺酮衍生物的合成和研究了他们的能力来抑制β-血色素形成,血红蛋白水解和体内啮齿动物对它们的功效伯氏疟原虫。化合物3b是最有希望的血红蛋白水解抑制剂,其作为β-血红素形成抑制剂的作用是有希望的。当芳环被2(Me),3(CF 3)或2,4(Cl)取代时,对血红蛋白水解的抑制作用最大(88%),其余化合物则保持较低的抑制作用。在体外和鼠类研究中出现的最活跃的化合物是3b建议通过多种机制进行抗疟活动。
