DL-Menthol ((±)-Menthol) is a racemic mixture of the monoterpene alcohols (–)-menthol and (+)-menthod, which have been found in Cannabis. (–)-Menthol is more common than (+)-menthol in nature and exhibits analgesic, antibacterial, and anticancer properties, as well as inhibits cholinesterase.2 (+)-Menthol inhibits the growth of F. verticillioides (MIC: 1.5 mM) but, unlike (–)-menthol, does not exhibit analgesic, antibacterial, anticancer, or cholinesterase inhibitory activities.

T443928319-77-9
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].

Bioactivity
Chemical Properties
| Description | Donepezil (Aricept) is a piperidine-based, potent, specific, and reversible inhibitor of acetylcholinesterase (AChE). It can be used for the treatment of mild to moderate dementia of the Alzheimer's type. |
| Targets&IC50 | AChE (bovine):8.12 nM, AChE (human):11.6 nM |
| In vitro | Donepezil has 500-1000-fold more selective for AChE over butyrylcholinesterase (BuChE). Short- and long-exposure of SH-SY5Y human neuroblastoma cells to donepezil induces a concentration-dependent inhibition of cell proliferation unrelated to muscarinic or nicotinic receptor blockade or apoptosis. Donepezil reduces the number of cells in the S-G2/M phases of the cell cycle, increases the G0/G1 population, and reduces the expression of two cyclins of the G1/S and G2/M transitions, cyclin E and cyclin B, in parallel with an increase in the expression of the cell cycle inhibitor p21. In addition, donepezil increases action potential-dependent dopamine release and modulates nicotinic receptors of substantia nigra dopaminergic neurons[1]. |
| In vivo | In plasma, urine, and bile, most donepezil metabolites are O-glucuronides. After oral ingestion, peak plasma concentrations are achieved in 3-5 hours and its absorption is not affected by food. Donepezil is slowly absorbed from the gastrointestinal tract and has a terminal elimination half-life of 50-70 hours in young volunteers (>100 hours in elderly subjects). After extensive metabolization in the liver, the parent compound is 93% bound to plasma proteins. Donepezil is metabolized in the liver via the cytochrome P450 system (CYP1A2-, CYP2D6-, CYP3A4-related enzymes). In animals, donepezil is found unchanged in the brain, and no metabolites are detected in the nervous tissue. Donepezil has linear pharmacokinetics over a dose range of 1-10 mg/day. 96% of circulating donepezil is protein bound [1]. |
| Cell Research | Cell lines: retinal ganglion cells (RGCs). Concentrations: 0.1-10 μM. Incubation Time: 3 days. RGC survival after exposure to each reagent (glutamate, donepezil, tacrine, galanthamine, and HA14-1) is measured by calcein-AM staining after 3 days in culture, Briefly, cells are incubated in 1 μM calcein-AM in PBS for 15 minutes at 37℃. After the medium is replaced with fresh PBS, cells are examined under a fluorescence microscope using a fluorescein filter. The total number of surviving RGCs defined as cells with a calcein-AM stained cell body and a process extending at least two cell diameters from the cell body is counted in each well. The number of surviving RGCs without any drug served as a control. |
| Animal Research | Animal Models: male C57BL/6 wild-type and CGRP(?/?) mice (10-12 weeks old, 21–24 g). Formulation: added to the food powder. Dosages: 1.5 mg/kg (i.g.) |
