sn-Glycero-3-phosphocholine (Choline glycerophosphate) is a natural choline compound found in the brain and in milk. It is also a parasympathomimetic acetylcholine precursor which may have a potential for the treatment of Alzheimer's disease and dementia. sn-Glycero-3-phosphocholine rapidly delivers choline to the brain across the blood–brain barrier and is a biosynthetic precursor of the acetylcholine neurotransmitter. It is a non-prescription drug in most countries due to its Generally Recognised As Safe (GRAS) status [1]. Studies have investigated its efficacy for cognitive disorders including stroke and Alzheimer's disease. An Italian multicentre clinical trial on 2, 044 patients suffering from recent stroke were supplied Glycerylphosphorylcholine in doses of 1, 000 mg day for 28 days and 400 mg three times per day for the five ensuing months. The trial confirmed the therapeutic role of alpha-GPC on the cognitive recovery of patients based on four measurement scales, three of which reached statistical significance [2].

1. Swertianolin (Bellidifolin-8-O-Glucoside), mangiferin, rhodenthoside A-C, isoorientin, isovitexin, and amarogentin would serve as potential chemotaxonomic markers to differentiate Gentianaceae species. 2. Swertianolin and swertiamarin show significant hepatoprotective effect in the liver damage model induced by alpha-naphthylisot hiocyanate. 3. Swertianolin shows anti-acetylcholinesterase activity effects. 4. Swertianolin shows that it can scavenge superoxide and hydroxyl radicals with the studying method of the autoxidation of Pyrogallol and afenton.

Coumaran (2,3-Dihydrobenzofuran), an acetylcholinesterase (AChE) inhibitor isolated from the leaves of L. camara, can be used as a biopesticide and belongs to the class of 1-benzofurans as the 2,3-dihydro derivative of benzofuran with a role as a metabolite.

Physostigmine, a parasympathomimetic alkaloid, is a reversible cholinesterase inhibitor. It extracts from the Calabar bean.

Protriptyline Hydrochloride is the hydrochloride salt form of protriptyline, a tricyclic secondary amine with an antidepressant property. Protriptyline hydrochloride (Protriptyline HCl) blocks the re-uptake of norepinephrine and serotonin by nerve terminals, thereby increasing available norepinephrine and serotonin. In addition, this agent exhibits anticholinergic activity.

Galanthamine N-Oxide, an alkaloid extracted from Zephyranthes concolor bulbs, effectively inhibits acetylcholinesterase (AChE) from electric eel with an EC50 of 26.2 μM. It acts as a significant inhibitor of substrate accommodation within the active sites of Torpedo californica AChE (TcAChE), human AChE (hAChE), and human BChE (hBChE) enzymes.

Garcinol also inhibits histone acetyltransferases (HATs, IC50= 7 μM) and p300 CPB-associated factor (PCAF, IC50 = 5 μM). Garcinol has anti-inflammatory and anti-cancer activity. Garcinol, a polyisoprenylated benzophenone harvested from Garcinia indica, exerts anti-cholinesterase properties towards acetyl cholinesterase (AChE) and butyrylcholinesterase (BChE) with IC50s of 0.66 μM and 7.39 μM, respectively.

Epi-galantamine, a diastereomer of galantamine, is an alkaloid extracted from the bulbs and flowers of the Caucasian snowdrop (Galanthus woronowii). It acts as an AChE inhibitor, featuring an EC50 of 45.7 μM.

Neostigmine bromide is a cholinesterase inhibitor used in the treatment of myasthenia gravis and to reverse the effects of muscle relaxants such as gallamine and tubocurarine. Neostigmine, unlike PHYSOSTIGMINE, does not cross the blood-brain barrier.

Isoimperatorin is an anti-inflammatory agent, exhibits significant inhibitory effects on acetylcholinesterase (AChE).

(-)-Huperzine A (HupA) , an active Lycopodium alkaloid extracted from the traditional Chinese herb, is a potent, selective and reversible acetylcholinesterase (AChE) inhibitor and has been widely used in China for the treatment of Alzheimer's disease (AD).

Rhodiosin is a compound with antioxidant activity.

Demecarium bromide (BC-48) is a potent cholinesterase inhibitor,and is treatment glaucoma agent.

N-Acetyl-L-aspartic acid is a derivative of aspartic acid, synthesized in neurons from the amino acid aspartic acid and acetyl coenzyme A. N-Acetyl-L-aspartic acid has antioxidant activity.

N-p-trans-Coumaroyltyramine is a natural product and an acetylcholinesterase (AChE) inhibitor with an IC50 of 122 μM. It also exhibits anti-trypanosomal activity with an IC50 of 13.3 μM for T. brucei rhodesiense.

Isomerazin (Isomeranzin) has anti-inflammatory activity, it suppresses inflammation by inhibiting M1 macrophage polarization through the p65, NF-κB and ERK pathway.

Manghaslin (Quercetin 3-O-rutinoside-(1->2)-O-rhamnoside) has considerable α-glucosidase inhibitory activity, illustrating the anti-diabetic potential of phenolic-rich litchi pulp extracts. Manghaslin also shows inhibitory activity against AChE

Sophoflavescenol is a mixed inhibitor of PDE5 with a K(i) value of 0.005 microM. Sophoflavescenol has antioxidant, anti-inflammatory, and apoptotic effects , these effects might contribute to the antitumor activity without severe side effects. Sophoflaves
