deaths every year, making it one of the most dangerous infectious diseases worldwide. Because the pathogens have developed resistance against most of the established anti-malarial drugs, new antiplasmodial agents are urgently needed. In analogy to similar antiplasmodial ketones, 4-arylthieno[2,3-b]pyridine-2-carboxamides were synthesized by Thorpe-Ziegler reactions. In contrast to the related ketones
疟疾每年导致数十万人死亡,使其成为全球最危险的传染病之一。由于病原体已对大多数已建立的抗疟疾药物产生抗药性,因此迫切需要新的抗疟药。与类似的抗疟原虫酮类似,4-芳基噻吩并[2,3-b]吡啶-2-甲酰胺是通过索普-齐格勒反应合成的。与相关酮相比,这些羧酰胺只是疟原虫酶 PfGSK-3 的弱抑制剂,但这些化合物仍然显示出很强的抗寄生虫活性。最有效的代表以两位数纳摩尔范围内的 IC50 值抑制病原体,并表现出高选择性指数 (>100)。
