studies showed that 3 g targets the food vacuole of the parasite and inhibits hemoglobin uptake, β‐hematin formation, and the basic endocytic processes of the parasite. Analogue 3 g was found to be orally bioavailable, and its curative antimalarial studies at 50 mg per kg p.o. against a Plasmodium berghei (ANKA)‐infected mouse model revealed that mice treated with 3 g showed 27–35 % suppression of parasitemia
一系列吲哚并[3,2-的b ]喹啉-C11羧酰胺通过氨基烷基侧链的掺入合成为吲哚并[3,2-的核心b ]喹啉-C11羧酸。它们在体外对抗疟原虫评价恶性疟原虫导致了2-(哌啶-1-基)乙胺联类似物2-溴的识别ñ - [2-(哌啶-1-基)乙基] -10 ħ -吲哚并[3,2- b ]喹啉-11-甲酰胺(3克)}(IC 50 = 1.3μ米),为显示出对哺乳动物细胞系的良好选择性指数最有前途的化合物。对红细胞阶段寄生虫的杀灭动力学表明3 g仅杀死了滋养体阶段的寄生虫。机理研究表明,3 g可以杀死寄生虫的食物液泡,并抑制其吸收血红蛋白,β-血红素形成以及该寄生虫的基本内吞过程。发现类似物3 g具有口服生物利用度,并且针对伯氏疟原虫(ANKA)感染的小鼠模型以每千克po 50 mg的治疗性抗疟疾研究显示,用3 g治疗的小鼠显示出27-35%的寄生虫病抑制率增加相对于未经治疗的对照小鼠,其寿命更长。因此,目前的工作证明了吲哚[3
