Malaria is still one of the most dangerous infectious diseases and the emergence of drug resistant parasites only worsens the situation. A series of new tetrahydro-β-carbolines were designed, synthesized by the Pictet–Spengler reaction, and characterized. Further, the compounds were screened for their in vitro antiplasmodial activity against chloroquine-sensitive (D10) and chloroquine-resistant (W2)
疟疾仍然是最危险的传染病之一,抗药性寄生虫的出现只会使情况恶化。设计了一系列新的四氢-β-咔啉,通过 Pictet-Spengler 反应合成并进行了表征。此外,筛选了这些化合物对氯喹敏感 (D10) 和氯喹抗性 (W2) 恶性疟原虫菌株的体外抗疟原虫活性。此外,还进行了分子建模研究以评估设计分子的潜在作用,并对人微血管内皮 (HMEC-1) 细胞系和人红细胞进行毒性测定。我们的研究确定了N-(3,3-二甲基丁基)-1-辛基-2,3,4,9-四氢-1H-吡啶并[3,4-b]吲哚-3-甲酰胺( 7 )(非对映异构体的混合物)具有最高抗疟原虫活性、最高选择性和无细胞毒性的有前途的化合物。对 (1 S ,3 R ) -7进行的计算机模拟提供了有用的见解,以了解其可能与寄生虫代谢所必需的酶的相互作用。正在进行进一步的研究以开发用于该化合物的最佳纳米级脂质递送系统并确定其精确的作用机制。
