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].

Cyclic N-Acetyl-D-mannosamine is a monosaccharide used as a precursor in the chemical or enzymatic synthesis of neuraminic acid found in glycolipids and glycoproteins.N-Acetyl-D-mannosamine is a specific substrate for the synthesis of n -acetylneuraminic acid, an essential precursor for bacterial podoplanar polysialic acid (PA).N-Acetyl-D-mannosamine is used in the synthesis of sialic acid. mannosamine is used in the synthesis of sialic acid. It is also an intermediate in the synthesis of many carbohydrate-derived bioactive compound families and drug candidates.N-Acetyl-D-mannosamine is used in the study of cognitive disorders and aging.

Sarcosine (Methylglycine) is a competitive inhibitor of the type I glycine transporter (GlyT1) and an N-methyl-D-aspartate receptor (NMDAR) co-agonist.

2,3-Dihydroxy-4-methoxyacetophenone (2',3'-Dihydroxy-4'-methoxyacetophenone) is a natural product,it improves cognitive function and may be helpful for the treatment of Alzheimer's disease.

1. Orientin (Luteolin-8-glucoside) may be regarded as a candidate therapeutic agent for treatment of vascular inflammatory diseases via inhibition of the HMGB1 signaling pathway. 2. Orientin protects vascular barrier integrity by inhibiting hyperpermeability, expression of CAMs, and adhesion and migration of leukocytes, thereby endorsing its usefulness as a therapy for vascular inflammatory diseases. 3. Orientin has neuroprotection effect by the intracellular mediation of caspase activity; may alleviate cognitive deficits and oxidative stress in AD mice; can exert antidepressant-like effects on CUMS mice, specifically by improving central oxidative stress, neurotransmission, and neuroplasticity.

Galactose prevents cognitive deficits in male Wistar rats.

Paxilline is an indole alkaloid mycotoxin from *Penicillium paxilli*, acting as a potent BK channel inhibitor via an almost exclusively closed-channel block mechanism. Paxilline possesses significant anticonvulsant activity.

24(S)-hydroxy Cholesterol (24S-OHC) is the terminal product of the cholesterol elimination pathway in neural tissues. It is an LXR agonist and a selective positive allosteric modulator of NMDARs. It can serve as a biomarker for NPD, induce cognitive decline in mice, and is useful for studying neurological diseases.
