Acetylcholinesterase inhibitory potencies of new pyrazoline derivatives

Alzheimer's disease (AD) has no current cure and its mechanism is not fully known, but treatments forsymptoms are available. Acetylcholinesterase (AChE) has been reported to be an applicable therapeutic target inpatient with AD. Acetylcholinesterase inhibitors (AChEIs) are commonly used for it. For this purpose, novel series ofpyrazoline based compounds [2-(3-(4-methoxyphenyl)-5-aryl-4,5-dihydro-1H-pyrazol-1-yl)benzo[d]thiazole, 1-9] were synthesized and AChE inhibitory potencies were reported here. The results indicated that compound 1 (Ki=0.13±0.004 μM) possessed the highest AChE inhibitory effect in series, which is two times more potent than thereference compound Tacrin (Ki= 0.26±0.045 μM). So, pyrazoline derivative 1 can be considered as a lead inhibitor in designing new AChE inhibitors.
