Calculated ADMETox parameters of the designed analogs revealed their good pharmacokinetic profiles indicating lipophilic characteristics. In vitro AChE enzyme test showed that obtained a-aminonitriles could be considered as AChEIs with micromolar IC50 values ranging from 42.0 to 478.0 mM (10.3e124.0 mg/mL). Among this series, the best AChE inhibitor was the pyrrolidine a-aminonitrile 3 (IC50 ¼ 42 mM), followed by the piperidine a-aminonitriles 2 and 6 (IC50 ¼ 45 mM and IC50 ¼ 51 mM, respectively), and the compound 7 (IC50 ¼ 51 mM). In vivo insecticidal activity of more active AChEIs against Aedes aegypti larvae was also performed showing a good larvicidal activity at concentrations less than 140 ppm, highlighting products 2 and 7 that could serve as lead compounds to develop new potent and selective insecticides.pdf9 páginasenginfo:eu-repo/semantics/embargoedAccessArtículo científicoContiene 44 referencias bibliográficas.
