Highly selective carbamate-based butyrylcholinesterase inhibitors derived from a naturally occurring pyranoisoflavone

This current study described the design and synthesis of a series of derivatives based on a natural pyranoisaflavone, which was obtained from the seeds of Millettia pachycarpa and displayed attractive BChE inhibition and high selectivity in our previous study. The inhibitory potential of all derivatives against two cholinesterases was evaluated. Only a few compounds demonstrated AChE inhibitory activity at the tested concentrations, while 26...
