Tryptophan-derived selective nanomolar butyrylcholinesterase inhibitors with great potential for symptomatic therapy against Alzheimer's disease are disclosed.
The core structure of a natural product was selected as scaffold for combinatorial library synthesis. The key step for the construction of the 3,9-diazabicyclo[3.3.1]non-6-ene core is a novel Dakin-West/Pictet-Spengler reaction sequence. Route selection for library synthesis was determined by solution-phase experiments. The solid-phase synthesis was developed based on the synthesis worked out in solution. A number of resins and linkers were studied to obtain the best loading and cleavage conditions. Potential target scaffolds using tryptophan, histidine and phenylalanine as building blocks were investigated. These efforts led to the development of a synthesis protocol for a tetracyclic scaffold incorporating tryptophan, useful for the preparation of a combinatorial library.
