Palmidrol (palmitoylethanolamide, PEA) is a natural fatty acid amide found in a variety of foods, which was initially identified in egg yolk. It is an endogenous compound, locally synthesized in animal and human tissues and body fluids, to protect against perturbing inflammation. In addition to its anti-inflammatory activity, palmidrol (palmitoylethanolamide, PEA) also produces analgesia, neuroprotection, and possesses anti-epileptic properties. It also reduces gastrointestinal motility and cancer cell proliferation, as well as protecting the vascular endothelium in the ischemic heart. The physiological stimuli that regulate palmidrol (palmitoylethanolamide, PEA) levels in mammalian tissues are largely unknown, however, multiple studies indicate that this lipid accumulates during cellular stress, particularly following tissue injury. Palmidrol (palmitoylethanolamide, PEA) is a potent and selective agonist of orphan receptor GPR55.

Chrysin (aka 5,7-dihydroxyflavone) is a naturally occurring flavone found in honey, propolis, honeycomb, passion flowers, and Oroxylum indicum. Chrysin is used as an ingredient in dietary supplements and topical medications which are marketed to improve physical performance o treat various conditions. It has also been investigated for its immunoregulatory, anti-inflammatory an neuroprotective properties. Chrysin appears to be poorly absorbed and readily metabolize.

Tramiprosate is a glycosaminoglycan mimetic designed to interfere with the actions of beta-amyloid peptides (Abeta) early in the cascade of amyloidogenic events. It is a patented variant of the amino acid taurine, which is reported to inhibit the interaction of Abeta with endogenous glycosaminoglycans and thereby prevent beta-sheet formation. Preclinical data have shown that tramiprosate reduces brain and plasma levels of Abeta, prevents fibril formation and exerts cytoprotective effects in the brain. The pharmacological effects have also been demonstrated in clinical trials of patients with mild to moderate Alzheimer's disease. Promising findings for the efficacy of tramiprosate, indicated by improvement or stabilization of cognitive function, have been shown in phase II clinical trials and open-label extensions of these studies. Furthermore, tramiprosate appears to be well tolerated with no reports of safety concerns. Tramiprosate is in phase III clinical trial for the treatment of Alzheimer's disease.

Polydatin (PD, also named pieceid, (E)-piceid, (E)-polydatin, trans-polydatin, 3,40 ,5-trihydroxystilbene-3-b-D-glucoside) is a monocrystalline compound originally isolated from the root and rhizome of Polygonum cuspidatum Sieb. et Zucc. (Polygonaceae), a traditional Chinese medicine that has long been used in China as an analgesic, anti-pyretic, diuretic and expectorant. It is a glucoside of resveratrol (3,40 ,5-trihydroxystilbene) in which the glucoside group bound to the position C-3 substitutes a hydroxyl group, belonging to stilbene phytoalexins. Polydatin can also be detected in grape, peanut, hop cones, red wines, hop pellets, cocoa-containing products, chocolate products and many daily diets. Polydatin is the most abundant form of resveratrol in nature. Polydatin shows many pharmacological effects confirmed by numerous investigations, including cardiovascular protection, neuroprotection, anti-inflammation, immunoregulation, anti-oxidation, anti-tumour and liver and lung protective effects. Polydatin has found its way into clinical trials for the treatment of hemorrhagic shock and irritable bowel syndrome.

Octacosanol, a low–molecular-weight primary aliphatic alcohol, is the main component of a natural product wax extracted from plants. Most studies have used a wheat-germ oil extract, or policosanol, a natural mixture of primary alcohols isolated from sugar cane wax, of which octacosanol is the main component (approximately 67% of policosanol is octacosanol). It has a number of indications for its use, many of which are currently being researched. Moreover, a small controlled study showed that some patients with mild Parkinsonism claimed of benefit from octacosanol. Although some research has been conducted using policosanol, little research is currently available that focuses on octacosanol alone. Studies have also found that octacosanol may inhibit the production of cholesterol. In the early 1990s, researchers at Dalmer Laboratories in La Habana Cuba isolated and produced the first policosanol (PC) supplement. The original PC supplement has been approved as a cholesterol-lowering drug in over 25 countries throughout the Caribbean and South America. Cuban studies claim that 1 to 20 mg/day of the original PC supplement are effective at producing significant reductions in total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C). These studies also show that PC supplements are potent antioxidants, promote proper arterial endothelial cell function, inhibit platelet aggregation and thrombosis, and serve as effective treatments for intermittent claudication. However, for the most part, those studies reporting therapeutic efficacy of PC were carried out by one research group situated in Cuba. Conversely, research groups outside of Cuba have failed to validate the cholesterol-lowering and antioxidant efficacy of PC. Cuban researchers, however, continue to claim that the efficacy is attributed to the unique purity and composition of the original PC preparation, a mixture not found in PC products used by external research groups. The absence of independent and external studies confirming the therapeutic benefits of PC in disease prevention and treatment raises questions regarding their true efficacy. Octacosanol also may prevent from atherosclerosis through activation of the PI3K/Akt and MAPK/Erk1/2 signaling pathways.

Mangiferin, a bioactive compound derived primarily from Anacardiaceae and Gentianaceae families and found in mangoes and honeybush tea, has been extensively studied for its therapeutic properties. Mangiferin has shown promising chemotherapeutic and chemopreventative potential. In traditional medicine, different cultures have cultivated and processed mangiferin rich plants for the treatment of a range of illnesses including cardiovascular disease, diabetes, infection and cancer. Mangiferin is primarily implicated in down-regulating inflammation, causing cell cycle arrest, reducing proliferation/metastasis, promoting apoptosis in malignant cells and protecting against oxidative stress and DNA damage. Mangiferin also enhances the capacity of the monocyte-macrophage system and possesses antibacterial activity against gram-positive and gram-negative bacteria.

ERGO (Ergothioneine) is naturally occurring antioxidant derived from the diet and abundantly contained in golden oyster mushroom (Pleurotus cornucopiae var. citrinopileatus. It is hydrophilic and membrane impermeable, but is well absorbed from the gastrointestinal tract due to the presence of a specific carrier‐mediated transport system, carnitine/organic cation transporter OCTN1/SLC22A4, essential for the beta-oxidation of fatty acids. Numerous in vitro assays have demonstrated the antioxidant and cytoprotective capabilities of ERGO against a wide range of cellular stressors, but an antioxidant role has yet to be fully verified in vivo. Nevertheless, the accumulation, tissue distribution, and scavenging properties, all highlight the potential for EGT to function as a physiological antioxidant. Because ERGO is highly distributed into the brain after oral ingestion, OCTN1 may contribute to the alleviation of oxidative stress and promotion of neuronal differentiation via the uptake of ERGO in the brain, perhaps abating symptoms of neurological disorders.
