Acetylcholinesterase is a member of the alpha/beta hydrolase protein super family, with a significant role in acetylcholine-mediated neurotransmission. Research in the modulators of AChEs has moved from a potent poison (Sarin, Soman) in war times to the potent medicine (physostigmine) in peaceful times. Natural anti-AChE includes carbamates, glycoalkaloids, anatoxins derived from green algae; synthetic anti-AChE includes highly poisonous organophosphates used as nerve gases and insecticides. Recently, the role of anti-AChE was reassessed from neurotoxins to neuron-protective in the diseases characterized by impaired acetylcholine-mediated neurotransmission like Alzheimer's disease (AD). So, the AChE has been proven to be the most viable therapeutic target for the symptomatic treatment of AD. This review article gives a spectrum of strategies to design AChE inhibitors used in the Alzheimer therapy.
