Evaluation of derivatives of 2,3-dihydroquinazolin-4(1H)-one as inhibitors of cholinesterases and their antioxidant activity: In vitro, in silico, and kinetics studies

In search of potent inhibitors cholinesterase enzymes and antioxidant agents, synthetic derivatives dihydroquinazolin-4(1H)-one 1-38 were evaluated as potential anti-Alzheimer agents through in vitro acetylcholinesterase (AChE) butyrylcholinesterase (BChE) inhibitions radical (DPPH ABTS) scavenging activities. The (SAR) was mainly based on the different substituents at aryl part which showed a significant effect inhibitory kinetic studies most active compounds noncompetitive mode inhibition for AChE competitive BChE enzyme. Additionally, molecular modeling carried out to investigate possible binding interactions quinazolinone with site both enzymes.
