activities against erythrocytic stage of chloroquine-sensitive strain of P. falciparum (Pf3D7). After analysing the QSAR model, new harmicines were designed and synthesized: six amide-type, eleven carbamate-type and two ureido-type harmicines at the N-9 position of the β-carboline core. Subsequently, we evaluated the antiplasmodial activity of the new harmicines against the erythrocytic and hepatic stages
疟疾是最古老的寄生虫病之一,仍然是全球健康威胁,疟疾寄生虫对当前抗疟药的抵抗力不断增强,迫使人们发现新的有效药物。骆驼蓬碱是一种杂合化合物,其中骆驼蓬碱/β-咔啉生物碱和肉桂酸衍生物通过酰胺键或三唑环连接,是新型抗疟原虫药物的代表。在这项工作中,我们基于 40 种先前制备的酰胺型 (AT) 鼠疫胺及其对氯喹红细胞阶段的抗疟原虫活性,使用多元线性回归技术建立了线性定量构效关系 (QSAR) 模型。恶性疟原虫敏感菌株(Pf 3D7)。在分析QSAR模型后,在β-咔啉核心的N-9位置设计并合成了新的骆驼蓬碱:6个酰胺型、11个氨基甲酸酯型和2个脲基型骆驼蓬碱。随后,我们在体外评估了新的骆驼蓬菌素对疟原虫生命周期的红细胞和肝阶段的抗疟原虫活性以及它们对 HepG2 细胞的抗增殖活性。UT 骆驼蓬碱 ( E )-1-(2-(7-甲氧基-1-甲基-9 H-吡啶并[3,4– b ]吲哚-9-基)乙基)-3-(3-(3-(三氟甲基)
