An efficient and economical synthesis of a series of rationally
designed novel
9,9′-(alkane-1,ω-diyldiimino)-1,2,3,4-tetrahydroacridines
(ω = 7–10) and a second series of new analogues,
9-(ω-phenylalkylamino)-1,2,3,4-tetrahydroacridines
(ω = 4–10), is reported. Compounds in the first
series are found to be up to 10 000-fold more selective and
1000-fold more potent in reversibly inhibiting rat acetylcholinesterase
(AChE) than the monomer, 9-amino-1,2,3,4-tetrahydroacridine (THA). Some
members in the latter series (ω = 7–8) are
slightly more potent than THA in inhibiting AChE but still more selective.
These compounds can serve as (i) important chemical tools to evaluate the
role of AChE inhibition by THA, a clinical drug, in treating
Alzheimer’s disease, (ii) effective, safer and low-cost insecticides
and parasiticides, (iii) potential blockers of the K+ channel
and the N-methyl-D-aspartate receptor channel, and
perhaps (iv) improved therapeutics for Alzheimer’s
disease.
报道了一种高效经济的合成一系列合理设计的新型9,9′-(烷-1,ω-二亚氨基)-1,2,3,4-四氢吖啶(ω=7-10)及其第二系列新类似物,9-(ω-苯基烷基氨基)-1,2,3,4-四氢吖啶(ω=4-10)的方法。第一系列化合物对大鼠乙酰胆碱酯酶(AChE)的可逆抑制作用比单体9-氨基-1,2,3,4-四氢吖啶(THA)的选择性高10000倍,效力高1000倍。在后一系列化合物中,某些成员(ω=7-8)抑制AChE的效力略高于THA,但仍更具选择性。这些化合物可作为(i)重要的化学工具,评估临床药物THA在治疗阿尔茨海默病中抑制AChE的作用,(ii)有效、更安全、低成本的杀虫剂和驱虫剂,(iii)潜在的钾通道和N-甲基-D-天冬氨酸受体通道阻滞剂,以及(iv)改进的阿尔茨海默病治疗药物。
