the eight (4,5-dihydropyrazol-1-yl) chloroquine 2 derivatives tested showed a significant activity in vitro, thus, are a promising new class of antimalarials. The three most active ones were also tested in vivo against Plasmodium berghei in mice. However, the (pyrazol-1-yl) chloroquine 3 derivatives were mostly inactive, suggesting that the aromatic functionality of the pyrazole ring was critical.
由1,1,1-三氟-4-甲氧基-3-烯丙基-2-酮与4-肼基-7-氯喹啉反应合成的氯喹吡唑类似物的抗疟活性已在体外针对氯喹进行了评估。抗性恶性疟原虫克隆。与没有药物的对照相比,通过掺入[(3)H]次黄嘌呤来测量存在试验药物的寄生虫的生长。测试的八种(4,5-二氢吡唑-1-基)氯喹2衍生物中,除一种化合物外,其他化合物均在体外具有显着活性,因此是一类有前途的新型抗疟药。还在小鼠中对三种活性最强的伯氏疟原虫进行了体内测试。然而,(吡唑-1-基)氯喹3衍生物大部分是无活性的,这表明吡唑环的芳族官能度是关键的。
