All approved drugs for Alzheimer disease (AD) in clinical practice ameliorate the symptoms of the disease. Among them, acetylcholinesterase inhibitors (AChEIs) are used to increase the cholinergic activity. Among new AChEI, tacrine compounds were found to be more toxic compared to 7-MEOTA (9-amino-7-methoxy-1,2,3,4-tetrahydroacridine). In this Letter, series of 7-MEOTA analogues (N-alkyl-7-methoxytacrine)
在临床实践中,所有批准用于阿尔茨海默氏病(AD)的药物均可改善该疾病的症状。其中,乙酰胆碱酯酶抑制剂(AChEI)用于增加胆碱能活性。在新的AChEI中,发现他克林化合物的毒性比7-MEOTA(9-氨基-7-甲氧基-1,2,3,4-四氢ac啶)高。在这封信中,合成了一系列的7-MEOTA类似物(N-烷基-7-甲氧基他克林)。评价了它们对重组人乙酰胆碱酯酶(AChE)和血浆人丁酰胆碱酯酶(BChE)的抑制能力。三种新型化合物显示出对hAChE优于THA或7-MEOTA的有希望的结果。产生了三种化合物作为hBChE的有效抑制剂。SAR结果突出了C 6 –C 7 N-抑制胆碱酯酶的烷基链。
