AbstractAedes aegypti is associated with the transmission of numerous human and animal diseases, such as yellow fever, dengue fever, chikungunya, and more recently Zika virus. Emerging insecticide resistance has created a need to develop new mosquitocidal agents for effective control operations. A series of benzothiazole-piperidine derivatives (1-24) were investigated for their larvicidal and adulticidal effects on Ae. aegypti It was observed that compounds 2, 4, 6, 7, 8, 11 and 13 showed notable larvicidal activity. Furthermore, compounds 6 and 10 showed promising adulticidal activity. Based on the mosquitocidal properties of these compounds, docking studies were also carried out in the active site of the AeSCP2 enzyme to explore any insights into further in vitro enzyme studies. Docking results indicated that all these active compounds showed reasonable interactions with critical residues in the active site of this enzyme. This outcome suggested that these compounds might show their larvicidal and adulticidal effects via the inhibition of AeSCP2. According to in vitro and in silico studies, compounds 2, 4, 6, 7, 8, 10, 11 and 13 stand out as candidates for further studies.
《摘要》
Aedes aegypti与许多人类和动物疾病的传播有关,如黄热病、登革热、基孔肯亚病毒,以及最近的寨卡病毒。新兴的
杀虫剂抗性已经导致需要开发新的蚊虫杀灭剂来进行有效的控制操作。对一系列
苯并噻唑-
哌啶衍
生物(
1-24)进行了研究,以评估它们对
Ae. aegypti的幼虫和成虫的杀虫效果。观察到化合物
