New Tetrahydroacridine Hybrids with Dichlorobenzoic Acid Moiety Demonstrating Multifunctional Potential for the Treatment of Alzheimer’s Disease

Abstract: A series of new tetrahydroacridine and 3,5-dichlorobenzoic acid hybrids with different spacers were designed, synthesized, and evaluated for their ability to inhibit both cholinesterase enzymes. Compounds 3a, 3b, 3f, and 3g exhibited selective butyrylcholinesterase (EqBuChE) inhibition with IC50 values ranging from 24 to 607 nM. Among them, compound 3b was the most active (IC50 = 24 nM). Additionally, 3c (IC50 for EeAChE = 25 nM and IC50 for EqBuChE = 123 nM) displayed dual cholinesterase inhibitory activity a… Show more

“…An evaluation of the inhibitory potency towards AChE (EC 3.1.1.7, Electrophorus electricus ) and BuChE (EC 3.1.1.8, equine serum) was performed using a modified spectrophotometric Ellman’s method [ 29 , 34 ]. All necessary reagents for the study were purchased from Sigma Aldrich (Steinheim, Germany).…”

“…14,15 β-secretase (BACE1) and γ-secretase cleave their amyloid precursor protein (APP) to produce Aβ. 16 Aβ exists mainly in two main forms which are Aβ 1−40 and Aβ 1−42 . They had significant neurotoxicity and were also hallmark predictor of Alzheimer's disease (AD) disease.…”

“…The obtained results for 3,5-dichlorobenzoic acid derivatives inspired us to expand the syntheses and the scope of research for these promising hybrids. In this way, developed this group of molecules (presented in this publication) and design new structures cyclopentaquinoline that have never been published 36 . We elaborated new therapeutic compounds against ROS-mediated damage in AD.…”
