DOI: 10.1002/cmdc.202100272
Abstract: Novel pyridine‐containing sultones were synthesized and evaluated for their cholinesterase (ChE) inhibitory activity. Most of compounds showed selective acetylcholinesterase (AChE) inhibitory activity. The structure‐activity relationship (SAR) showed: (i) the fused pyridine‐containing sultones increase AChE inhibition,… read more here.
