In this paper we report the synthesis and antimalarial properties of two series of fluoroalkylated γ-lactams derived from 4-aminoquinoline as potent chemotherapeutic agents for malaria treatment. These molecules obtained in several steps resulted in the identification of very potent structures with in vitro activity against Plasmodium falciparum clones of variable sensitivity (3D7 and W2) in the range
在本文中,我们报告了衍生自4-氨基喹啉的两种系列氟烷基化γ-内酰胺类化合物的合成及抗疟疾特性,它们是用于治疗疟疾的有效化学治疗剂。通过分几步获得的这些分子导致鉴定出非常有效的结构,具有体外活性,可对19-50 nM范围内的可变敏感性(3D7和W2)恶性疟原虫克隆产生抗性,抗性指数在1.0-2.5范围内。此外,所选择的分子(50,51,58,60,63,70,72,74,78,81,84,和87)代表这两个系列的化合物,当针对浓度高达100μM的人脐静脉内皮细胞进行体外测试时,在体外未显示细胞毒性。最有前途的化合物(82和84)对氯喹敏感菌株3D7的IC 50值接近26和19 nM,对耐多药菌株W2的IC 50值接近49和42 nM。此外,发现两种模型化合物(50和70)在pH 7.4和5.2下可在48小时内保持稳定。总体而言,我们的初步数据表明此类结构包含有希望进一步研究的候选对象。
