previously published by our group. Additionally, three new 1,2,4-oxadiazoles, 10-12, have also been synthesized, characterized and studied. The QSAR and docking studies of all compounds, 1-12, clearly indicate that larger hydrophobic substituents such as biphenyl groups attached on position 3 in 1,2,4-oxadiazoles improve the larvicidal activity. It is worthwhile to mention that nanocapsulation of compounds
寨卡、登革热、基孔肯雅、西尼罗河病毒和黄热病等病毒性疾病在全球范围内的出现,促使人们寻找消灭其共同病媒埃及伊蚊的解决方案。本文介绍了我们课题组之前发表的九种 3-(3-芳基-
1,2,4-恶二唑-5-基)
丙酸(A
OPA)(1-9)系列的定量结构-活性关系(Q
SAR)和对接研究。此外,我们还合成、表征和研究了三个新的
1,2,4-恶二唑(10-12)。对所有化合物(1-12)进行的 Q
SAR 和对接研究清楚地表明,1,2,4-噁二唑中较大的疏
水取代基(如连接在第 3 位的
联苯基团)提高了杀幼虫剂的活性。值得一提的是,有必要对化合物 10-12 进行纳米封装,以帮助其溶解于
水,而且这三种新的
1,2,4-恶二唑在 L4 阶段也表现出与前原型大致相同或更高的杀幼虫剂活性。
