Cholinesterase (ChE) is a family of enzymes present in the central nervous system, particularly in nervous tissue, muscle and red cells, which catalyze the hydrolysis of the neurotransmitter acetylcholine into choline and acetic acid, a reaction necessary to allow a cholinergic neuron to return to its resting state after activation. It is one of many important enzymes needed for the proper functioning of the nervous systems of humans.

There are two types: acetylcholinesterase (AChE, acetylcholine hydrolase) and butyrylcholinesterase (BChE, acylcholine acylhydrolase), also known as nonspecific cholinesterase or pseudocholinesterase. AChE is primarily found in the blood on red blood cell membranes, in neuromuscular junctions, and in neural synapses, while BChE is produced in the liver and found primarily in plasma. The difference between the two types of cholinesterase is their relative preferences for substrates: AChE hydrolyzes acetylcholine faster while BChE hydrolyzes butyrylcholine faster.

    HUHS2002
    HUHS2002 is a free fatty acid derivative with the ability to enhance α7 cholinergic receptor activity. HUHS2002 enhances whole-cell membrane currents of α7 ACh receptors expressed in Xenopus oocytes in a concentration-dependent manner. The effects of HUHS2002 were blocked in the presence of the Ca2 /calmodulin-dependent protein kinase II (CaMKII) inhibitor KN-93. HUHS2002 activated CaMKII in cultured rodent hippocampal neurons, and this activation was abolished by KN-93. HUHS2002 also partially inhibited the activity of protein phosphatase 1 (PP1) in a cell-free PP1 activity assay.
