摘要: Abstract To provide a further test of the dual binding site hypothesis proposed for acetylcholinesterase (AChE) inhibitor heptylene-linked bis-(9-amino-1,2,3,4-tetrahydroacridine) A7A , short-tether (ethylene–hexylene) homologs A2A – A6A were prepared. En route to these compounds, convenient and scaleable syntheses useful pharmaceutical intermediate 9-chloro-1,2,3,4-tetrahydroacridine 3 developed. AChE butyrylcholinesterase (BChE) inhibition assays A10A confirm that seven methylene tether ( ) optimizes potency AChE/BChE selectivity. Finally, studies indicate simultaneous alkylene-linked 9-amino-1,2,3,4-tetrahydroacridine dimers catalytic peripheral sites is possible with length as short 5 methylenes. ©
