Terreulactone A is a meroterpenoid isolate of Aspergillus with anti-acetylcholinesterase activity. [1]
Cholinergic agents are compounds which mimic the action of acetylcholine and/or butyrylcholine. In general, the word "choline" describes the various quaternary ammonium salts containing the N,N,N-trimethylethanolammonium cation. Found in most animal tissues, choline is a primary component of the neurotransmitter acetylcholine and functions with inositol as a basic constituent of lecithin. Choline also prevents fat deposits in the liver and facilitates the movement of fats into cells.
The enzyme cholinesterase (EC 3.1.1.8, choline esterase; systematic name acylcholine acylhydrolase) catalyses the hydrolysis of choline-based esters:
Parathion, also called parathion-ethyl or diethyl parathion and locally known as "Folidol", is an organophosphate insecticide and acaricide. It was originally developed by IG Farben in the 1940s. It is highly toxic to non-target organisms, including humans, so its use has been banned or restricted in most countries. The basic structure is shared by parathion methyl.
A parasympathomimetic drug, sometimes called a cholinomimetic drug or cholinergic receptor stimulating agent, is a substance that stimulates the parasympathetic nervous system (PSNS). These chemicals are also called cholinergic drugs because acetylcholine (ACh) is the neurotransmitter used by the PSNS. Chemicals in this family can act either directly by stimulating the nicotinic or muscarinic receptors, or indirectly by inhibiting cholinesterase, promoting acetylcholine release, or other mechanisms. Common uses of parasympathomimetics include glaucoma, Sjögren syndrome and underactive bladder.
Diisopropyl fluorophosphate (DFP) or Isoflurophate is an oily, colorless liquid with the chemical formula C6H14FO3P. It is used in medicine and as an organophosphorus insecticide. It is stable, but undergoes hydrolysis when subjected to moisture.
Pralidoxime or 2-PAM, usually as the chloride or iodide salts, belongs to a family of compounds called oximes that bind to organophosphate-inactivated acetylcholinesterase. It is used to treat organophosphate poisoning in conjunction with atropine and either diazepam or midazolam. It is a white solid.
Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H25. Like monoterpenes, sesquiterpenes may be cyclic or contain rings, including many unique combinations. Biochemical modifications such as oxidation or rearrangement produce the related sesquiterpenoids.
Gliotoxin is a sulfur-containing mycotoxin that belongs to a class of naturally occurring 2,5-diketopiperazines produced by several species of fungi, especially those of marine origin. It is the most prominent member of the epipolythiopiperazines, a large class of natural products featuring a diketopiperazine with di- or polysulfide linkage. These highly bioactive compounds have been the subject of numerous studies aimed at new therapeutics. Gliotoxin was originally isolated from Gliocladium fimbriatum, and was named accordingly. It is an epipolythiodioxopiperazine metabolite that is one of the most abundantly produced metabolites in human invasive Aspergillosis (IA).
Acetylcholinesterase (HGNC symbol ACHE; EC 3.1.1.7; systematic name acetylcholine acetylhydrolase), also known as AChE, AChase or acetylhydrolase, is the primary cholinesterase in the body. It is an enzyme that catalyzes the breakdown of acetylcholine and some other choline esters that function as neurotransmitters:
Minaprine is a monoamine oxidase inhibitor antidepressant drug that was used in France for the treatment of depression until it was withdrawn from the market in 1996 because it caused convulsions.
Eseroline is a drug which acts as an opioid agonist. It is a metabolite of the acetylcholinesterase inhibitor physostigmine but unlike physostigmine, the acetylcholinesterase inhibition produced by eseroline is weak and easily reversible, and it produces fairly potent analgesic effects mediated through the μ-opioid receptor. This mixture of activities gives eseroline an unusual pharmacological profile, although its uses are limited by side effects such as respiratory depression and neurotoxicity.
Acetylcholinesterase inhibitors (AChEIs) also often called cholinesterase inhibitors, inhibit the enzyme acetylcholinesterase from breaking down the neurotransmitter acetylcholine into choline and acetate, thereby increasing both the level and duration of action of acetylcholine in the central nervous system, autonomic ganglia and neuromuscular junctions, which are rich in acetylcholine receptors. Acetylcholinesterase inhibitors are one of two types of cholinesterase inhibitors; the other being butyryl-cholinesterase inhibitors. Acetylcholinesterase is the primary member of the cholinesterase enzyme family.
Andrastin A is a farnesyltransferase inhibitor isolate of Penicillium species including Penicillium albocoremium and Penicillium roqueforti. It has been produced bio-synthetically by porting the relevant gene sequence into Aspergillus oryzae.
Corydaline is an acetylcholinesterase inhibitor isolated from Corydalis yanhusuo.
Oreobeiline is an morphinan alkaloid of Beilschmiedia with anti-acetylcholinesterase, anti-alpha-glucosidase, anti-leishmanial, and anti-fungal activities.
Sarcococca saligna, the sweet box or Christmas box, is a species of flowering plant in the family Buxaceae. This shrub is native to northern Pakistan. Its common name in Pakistan is sheha.
Huprine X is a synthetic cholinergic compound developed as a hybrid between the natural product Huperzine A and the synthetic drug tacrine. It is one of the most potent reversible inhibitors of acetylcholinesterase known, with a binding affinity of 0.026nM, as well as showing direct agonist activity at both nicotinic and muscarinic acetylcholine receptors. In animal studies it has nootropic and neuroprotective effects, and is used in research into Alzheimer's disease, and although huprine X itself has not been researched for medical use in humans, a large family of related derivatives have been developed.
Fumigatonin is a meroterpenoid of the fungi Aspergillus fumigatus with the molecular formula C28H38O11.
Aspergillus funiculosus is an anamorph species of fungus in the genus Aspergillus. Aspergillus funiculosus produces the funiculolides A-D and the antibiotic funicin.
Anditomin is an oxygenated meroterpenoid produced by Aspergillus stellatus or Aspergillus variecolor.
