Abstract:

Selective human butyrylcholinesterase (BChE) inhibitors such as cymserine have shown considerable promise for restoring cognition in Alzheimers disease. Recently, (-)-debromoflustramine B, 1, a hexahydropyrrolo-[2,3-b]indole natural product isolated from the marine bryozoan Flustra foliacea, has demonstrated micromolar potency as a selective BChE inhibitor. Since (±)-demethyldebromoflustramine B, (±)-2, has an even lower IC50, and the active enantiomer is (-)- 2, derivatives of (-)-2 were constructed in silico and docked into the active site of BChE. Several compounds exhibited improved inhibitor potency and could be candidates for future synthesis and in vitro enzyme inhibition study.
