The present work is directed to synthesize new tolerance binary pyrazolylquinolinone such as pyrazolylquinolinone, 1-phenylpyrazolyl)quinolinone and 1,2,4-triazolyl)pyrazolyl)quinolinone and fused pyrazolo-/pyridoquinolinone hybrids as pyrazolo[4,3-]quinolinone, benzo[][1,6]naphthyridinedione, tetrahydrobenzo[][1,6]naphthyridine-3-carbonitrile and 2,7-triazaindeno[4,5,6-]anthracenol as prospective ingredients with the aim of assessment for their antioxidant and insecticidal potentiality. Additionally, and insecticidal bio-responses, cotton leafworm, () and the cotton aphid were screened for the synthesized compounds. Interestingly, the most potent compounds were 11 and 5 with (LC 119.79 and 164.63 mg L) against . Furthermore, the influence of the tested compounds on biochemical parameters, including AChE, ATPase, total protein levels, detoxifying enzymes CaE, and GST were also inspected. Furthermore, the targeted compounds showed promising antioxidant activity comparable with ascorbic acid as the presence of both of functionalized quinolinone and pyrazole moieties increasing the scavenger radical inhibition. Finally, DFT calculations were implemented to investigate the electronic and structural properties of the synthesized scaffolds.
目前的工作旨在合成新的耐受性二元吡唑基喹啉酮,如吡唑基喹啉酮、1-苯基吡唑基喹啉酮和1,2,4-三唑基)吡唑基)喹啉酮,以及稠合的吡唑并/吡啶并喹啉酮杂化物,如吡唑并[4,3-]喹啉酮、苯并[][1,6]萘啶二酮、四氢苯并[][1,6]萘啶-3-腈和2,7-三氮杂茚并[4,5,6-]蒽醇,作为潜在成分,以评估它们的抗氧化和杀虫潜力。此外,还对合成的化合物进行了棉铃虫()和棉蚜的杀虫生物反应筛选。有趣的是,最有效的化合物是11和5,对棉铃虫的LC分别为119.79和164.63 mg/L。此外,还考察了受试化合物对生化参数的影响,包括乙酰胆碱酯酶、ATP酶、总蛋白水平、解毒酶羧酸酯酶和谷胱甘肽S-转移酶。此外,由于官能化喹啉酮和吡唑部分的存在增加了清除自由基的抑制作用,目标化合物显示出与抗坏血酸相当的有前景的抗氧化活性。最后,进行了密度泛函理论计算,以研究合成支架的电子和结构性质。
