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.

    Cubebin
    		Inhibitor
    Cubebin ((-)-Cubebin), a dibenzyl butyrolactone lignan, is an orally active AChE inhibitor. Cubebin binds to active sites of NF-κB, TNF-α, and TGF-β1 via hydrogen and hydrophobic interactions, obstructing critical residues to inhibit pro-inflammatory or renal fibrosis-related activity. Cubebin enhances p38 MAPK phosphorylation to increase tyrosinase gene expression, stimulating melanogenesis via elevated tyrosinase activity, expression, and mRNA levels. Cubebin reduces oxidative stress via enhanced endogenous antioxidant enzyme activity and inhibited lipid peroxidation, regulates lipid metabolism, improves glycemic control, and exerts renoprotective effects via reduced renal dysfunction markers and improved renal architecture. Cubebin shows antimicrobial activity. Cubebin exerts larvicidal activity against Angiostrongylus cantonensis larvae, with no cytotoxicity toward monkey or human cell lines or Caenorhabditis elegans. Cubebin can be used for the research of diabetic nephropathy, melanoma, colon adenocarcinoma, neuroangiostrongyliasis, Alzheimer’s disease (AD) and depression.
