the substituents in position 7 of tacrine and (b) a tentative assignment of the hydrophobic character to the favorable effect exerted by the substituents in position 6. Finally, a new previously unreported tacrine derivative designed on the basis of both the classical and the 3D QSAR equations was synthesized and kinetically evaluated, to test the predictive ability of the QSAR models. The 6-bromo-9-amino-1
在这项研究中,我们试图获得与他克林有关的乙酰胆碱酯酶(AChE)抑制剂类别的综合SAR图像,他克林是目前用于治疗阿尔茨海默氏病的药物。为此,我们合成并测试了一系列9-氨基-1,2,3,4-四氢ac啶衍生物,这些衍生物在the啶核的6和7位上取代,并在9-氨基官能团上带有选定的基团。通过Hansch方法,获得了QSAR方程,定量考虑了位置7的取代基的有害空间效应和9-氨基-1,2位置6和7的取代基所施加的有利的电子吸引作用, 3,4-四氢ac啶衍生物。通过对由12个9-氨基-1,2,3,4-四氢ac啶和13个11H-茚三酮制得的一系列AChE抑制剂进行CoMFA分析,考虑了抑制剂的三维(3D)特性。以前在我们实验室开发的2-b] quinolin-10-ylamines。通过利用对接模型计算待提交CoMFA程序的分子的比对,该模型针对未取代的9-氨基-1,2,3,4-四氢ac啶和11H-茚并[1
