diselenides containing electron-donating and electron-withdrawing groups, affording the corresponding 4-aryl-7-chloroquinolines in high yields. The synthesized compounds were screened for their in vitro acetylcholinesterase (AChE) activity and our results demonstrated that the 7-chloro-4-[(4-fluorophenyl)selanyl]quinoline inhibited the AChE activity and improved memory in mice, making this compound is a potential
我们在这里描述了通过4,7-二氯喹啉与有机基硒醇的反应合成4-芳基戊基-7-氯喹啉的另一种方法,该反应是由二有机基二硒化物与H 3 PO 2(在H 2 O中为50 wt%)反应原位生成的)。这些反应在60°C的N 2气氛下有效地进行,并且适合于一系列包含给电子和吸电子基团的二有机基二硒化物,以高收率提供了相应的4-芳基-7-氯喹啉。筛选合成的化合物的体外 乙酰胆碱酯酶(AChE)活性,我们的结果表明7-氯-4-[(4-氟苯基)硒基]喹啉可抑制AChE活性并改善小鼠的记忆力,从而使该化合物成为治疗阿尔茨海默氏病的潜在治疗剂和其他神经退行性疾病。
