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.

  • HY-118275
    FK960
    		Activator
    FK960 is a potential anti-dementia agent that reverses the reduction in cerebral blood flow (rCBF) caused by sensory stimulation by enhancing cholinergic neurotransmission. In macaque experiments, physostigmine (AChE inhibitor; HY-N6608) was able to completely eliminate the rCBF in the sensory cortex increased by vibrotactile stimulation. FK960 (1-1000 μg/kg) can restore the eliminated rCBF response, and the action time can last for 1 hour. However, FK960 cannot restore the rCBF response eliminated by HA-966 (NMDA modulator; HY-100822), indicating that its function is not dependent on non-glutamatergic neurotransmission.
