Synthesis and cholinesterase inhibitory activity studies of some piperidinone derivatives

Autor: Sülünay Parlar

Publikováno v: Organic Communications, Vol 12, Iss 4, Pp 202-209 (2019)

AA series of a,β-unsaturated carbonyl based piperidinone derivatives were synthesized and evaluated for their abilities to inhibit AChE and BuChE. All compounds exhibited AChE and BuChE inhibitory activity in different ratios. Among the series, comp
