Dimethyl malonate is a competitive inhibitor of succinate dehydrogenase (SDH). Dimethyl malonate is able to cross the blood-brain barrier and hydrolyse to malonate. Dimethyl malonate reduces neuronal apoptosis.

Xanthine, a plant alkaloid found in tea, coffee, and cocoa, is a mild stimulant of the central nervous system. Xanthine also acts as an intermediate product on the pathway of purine degradation.

Choline chloride is an orally active methylxanthine derivative. Choline chloride exhibits weak antihistaminic and anticholinergic activities and potentiates the effects of histamine and acetylcholine. Choline chloride relaxes bronchial smooth muscle, dilates coronary and peripheral blood vessels, increases urine output and electrolyte excretion, stimulates locomotor activity in the central nervous system, and induces transient hypotension following a pressor phase. Choline chloride modulates sleep architecture by increasing wakefulness time and reducing slow-wave sleep, without altering the frequency or severity of nocturnal hypoxemia, apnea, or hypopnea events. Choline chloride is used in studies of bronchospasm, nocturnal asthma, and chronic asthma.

Vitamin A (Vitamin A1) is an endogenous metabolite.

Lycopene is naturally occurring carotenoids found in tomato, tomato products, and in other red fruits and vegetables; exhibits antioxidant effects.

Trimethylamine N-oxide is a gut microbe-dependent metabolite of dietary choline and other trimethylamine-containing nutrients. Trimethylamine N-oxide induces inflammation by activating the ROS/NLRP3 inflammasome. Trimethylamine N-oxide also accelerates fibroblast-myofibroblast differentiation and induces cardiac fibrosis by activating the TGF-β/smad2 signaling pathway.

Benzo[a]pyrene shows lung carcinogenicity in animal models, and it is frequently used in chemoprevention studies.

Phytohemagglutinin P (PHA-P) is a mitogen known to selectively stimulate cells of hematogenous or lymphoid monocytic origin.

5Z-7-Oxozeaenol is a natural anti-protozoan compound from fungal origin, acting as a potent irreversible and selective inhibitor of TAK1 and VEGF-R2, with IC₅₀s of 8 nM and 52 nM, respectively.

6-Mercaptopurine is a purine analogue which acts as an antagonist of the endogenous purines and has been widely used as antileukemic agent and immunosuppressive drug.

Urea is a powerful protein denaturant via both direct and indirect mechanisms. A potent emollient and keratolytic agent. Used as a diuretic agent. Blood urea nitrogen (BUN) has been utilized to evaluate renal function. Widely used in fertilizers as a source of nitrogen and is an important raw material for the chemical industry.

Phosphatidylcholine is the main phospholipid component in eukaryotic biofilms. Phosphatidylcholine exists in commensal or pathogenic bacteria associated with eukaryotes in prokaryotes. Phosphorylcholine exhibits a surprising range of immunomodulatory properties.

S-Adenosyl-L-methionine (S-Adenosyl methionine) is an orally active methyl group donor. S-Adenosyl-L-methionine is a dietary supplement with potent antidepressant effects. S-Adenosyl-L-methionine also has anti‑proliferative, pro‑apoptotic and anti‑metastatic roles in cancers. S-Adenosyl-L-methionine has the potential for, cancer, liver disease and osteoarthritis research.

Uridine 5’-diphosphoglucose (UDP-glucose) disodium, secreted by cardiomyocytes during ischemia and reperfu, is a potent agonist of the proinflammatory P2Y14 receptor. It acts an important role in the regulation of inflammation and neutrophil polarization in neutrophils. Uridine 5’-diphosphoglucose disodium is also the precursor of glucose-containing oligosaccharides, polysaccharides, glycoproteins, and glycolipids in animal tissues and in some microorganisms. Uridine 5’-diphosphoglucose disodium is promising for research in counteracting myocardial infarction/reperfusion (MIR)-induced inflammation in the heart tissue.

Cabazitaxel is a semi-synthetic derivative of the natural taxoid 10-deacetylbaccatin III with potential antineoplastic activity.

6-Thioguanine (Thioguanine; 2-Amino-6-purinethiol) is an anti-leukemia and immunosuppressant agent, acts as an inhibitor of SARS and MERS coronavirus papain-like proteases (PLpros) and also potently inhibits USP2 activity, with IC₅₀s of 25 μM and 40 μM for Plpros and recombinant human USP2, respectively.

Calcifediol (25-hydroxy Vitamin D3) is an effective VDR ligand and VD supplement. Calcifediol is a prohormone of the vitamin D endocrine system (VDES) and is hydroxylated in the liver to produce the active form, calcitriol. Calcifediol can rapidly increase serum VD levels.

D-erythro-Sphingosine (Erythrosphingosine) is a very potent activator of p32-kinase with an EC₅₀ of 8 μM, and inhibits protein kinase C (PKC). D-erythro-Sphingosine (Erythrosphingosine) is also a PP2A activator.

Gastrodin, a main constituent of a Chinese herbal medicine Tianma, has been known to display anti-inflammatory effects. Gastrodin inhibits ethanol-induced hepatocellular apoptosis. Gastrodin inhibits H₂O₂-induced ferroptosis through its antioxidative effect. Gastrodin can be used for study of dizziness, epilepsy, stroke and dementia.

Phosphorylethanolamine (Monoaminoethyl phosphate) is a membrane phospholipid and an important precursor of Phosphatidylcholine (HY-N18891). It is found in most animal tissues and various human extracranial tumors, playing a critical role in membrane integrity, cell division, mitochondrial respiratory function, and more. Studies have shown that changes in the abundance of Phosphorylethanolamine are associated with Alzheimer's disease and Parkinson's disease. Lowering the ratio of Phosphorylethanolamine to Phosphatidylcholine in the liver can improve insulin signaling. Phosphorylethanolamine holds promise for research in the fields of cancer, neurodegenerative disorders, and metabolic diseases.
