Glycitin (4'-Hydroxy-6-Methoxyisoflavone-7-D-Glucoside) is a soy isoflavone. Isoflavone mixtures from soybean containing glycitin exert anti-obese and antidiabetic, antineoplastic, antioxidant effects. Isoflavone supplementation in healthy males may enhance cognitive processes which appear dependent on oestrogen activation. Glycitin underwent hydrolysis of the beta-glycoside moiety and little further biotransformation, leading to high plasma glycitein concentrations.

Astragaloside A (Astragaloside IV) is the primary pure saponin isolated from Astragalus membranaceus, which has been widely used for the treatment of cardiovascular diseases. Astragaloside IV improves post-ischemic heart function and ameliorated reperfusion arrhythmias accompanied by a significant increase in myocardial antioxidative enzyme superoxide dismutase activity in rat hearts in vitro. While, Astragaloside IV's protective effect on heart function can be partially abrogated by the nitric oxide synthase inhibitor, Nomega-nitro-L-arginine methyl ester. Astrageloside IV has multiple pharmacologic effects, including anti-inflammatory, antifibrotic, antioxidative stress, anti-asthma, antidiabetes, immunoregulation, and cardioprotective effect via numerous signaling pathways. According to the existing studies and clinical practices, Astragaloside A possesses potential for broad application in many diseases.

Malvidin-3-O-glucoside is a polyphenolic anthocyanin. Anthocyanins are flavonoids widely distributed in fruits and vegetables that exhibit antioxidative and anti-inflammatory bioactivities. Among other polyphenolic components, malvidin-3-glucoside is present in ViNitrox™ a natural dietary supplement from apple and grape, it offers a number of exceptional sports nutrition properties including enhanced and lasting performance.

Citiolone (N-acetylhomocysteine thiolactone) is an antioxidant drug used in the treatment of liver diseases.

Alpha-ketoglutarate (AKG), an endogenous intermediary metabolite in the Krebs cycle, is a molecule involved in multiple metabolic and cellular pathways. As an intermediate of the tricarboxylic acid cycle, AKG is essential for the oxidation of fatty acids, amino acids, and glucose. Extracellular AKG is a significant source of energy for cells of the gastrointestinal tract. As a precursor for the synthesis of glutamate and glutamine in multiple tissues (including liver, skeletal muscle, heart, brain, and white adipose tissue), AKG bridges carbohydrate and nitrogen metabolism for both conservation of amino acids and ammonia detoxification. Additionally, emerging evidence shows that AKG is a regulator of gene expression and cell signaling pathways (including the mammalian target of rapamycin and AMPactivated protein kinase). Thus, AKG is an attractive dietary supplement in animal and human nutrition to improve cellular energy status, immunity, and health.AKG can decrease protein catabolism and increase protein synthesis to enhance bone tissue formation in the skeletal muscles and can be used in clinical applications. In addition to these health benefits, a recent study has shown that AKG can extend the lifespan of adult Caenorhabditis elegans by inhibiting ATP synthase and TOR. Orally, AKG is used for kidney disease, gastrointestinal disorders, bacterial overgrowth, intestinal toxemia, liver dysfunction, and chronic candidiasis. It is also used for improving peak athletic performance, improving amino acid metabolism in hemodialysis patients, and cataracts. Intravenously, AKG is used for preventing ischemic injury during heart surgery, improving renal blood flow after heart surgery, and preventing muscle protein depletion after surgery or trauma.

Acetylcysteine amide (NACA) is a novel thiol-containing antioxidant. NACA is a modified form of its parent compound N-acetylcysteine (NAC) that is a precursor of the most abundant endogenous antioxidant, glutathione (GSH). NACA demonstrated the multiple therapeutic abilities, including antioxidant, anti-apoptotic, and anti-inflammatory properties with greater efficacy compared to its parent compound. NACA treatment significantly maintained acute mitochondrial bioenergetics and normalized GSH levels following spinal cord injury. It is a new neuroprotective drug, that might be effective at slowing down nigral neuronal degeneration and illness progression in patients with Parkinson's disease.

Tocopherol (alpha tocopheryl nicotinate) is an ester of tocopherol and nicotinic acid. Vitamin E (Tocopherol) is sold commercially as the esterified form (alpha tocopheryl acetate, alpha tocopheryl succinate and alpha tocopheryl nicotinate). Alpha tocopheryl nicotinate has antioxidant and vasodilatory properties. It can be used as a mild warming agent, without producing the redness typical for nicotinic acid. Tocopherol (alpha tocopheryl nicotinate) has been available in Japan since 1967. Tocopherol under the brand name Juvela N is approved in Japan for the treatment of symptoms accompanying hypertension, hyperlipidemia, peripheral circulatory disturbance resulting from arteriosclerosis obliterans. Tocopherol has being shown to inhibit platelet aggregation.

Tetraethylenepentamine (TEPA) is a low-molecular-weight linear polyamine exerting metal-chelating properties. TEPA is widely used in industrial applications. The principal hazards that arise in working with TEPA are those associated with similar organic amines; namely, a corrosive action on skin and eyes. TEPA biological activity was attributed to its effect on cellular Cu levels as (a) treatment with TEPA resulted in reduction of cellular Cu, and (b) excess of Cu reversed TEPA's activity and accelerated differentiation. TEPA was shown to attenuate the differentiation of ex vivo cultured hematopoietic cells resulting in preferential expansion of early progenitors. A phase I/II trial was performed to test the feasibility and safety of transplantation of CD133+ cord blood (CB) hematopoietic progenitors cultured in media containing stem cell factor, FLT-3 ligand, interleukin-6, thrombopoietin and TEPA. Transplanting a population of CD133+ CB cells which were expanded ex vivo for 21 days using SCF, FLT3, IL-6, TPO and the copper chelator TEPA (StemEx) was feasible. The expanded cells were well tolerated, with no infusion-related adverse events observed.

Saffron is a spice derived from the flower of Crocus sativus, commonly known as the "saffron crocus". Crocin is a water-soluble carotenoid pigment of saffron,that has been used as a spice for flavoring and coloring food preparations, and in Chinese traditional medicine as an anodyne or tranquilizer. Saffron is now used worldwide in folk medicine and is reputed to be useful in treating various human disorders such as heart and blood disorders. Stroke and heart attack are involved in reputed folkloric uses of saffron. Saffron is orally administrated as a decoction. Saffron extract exerts a protective effect on renal ischemia reperfusion induced oxidative damage in rats. Crocin suppresses tumor necrosis factor (TNF) alpha-induced apoptosis of pheochromocytoma (PC12) cells by modulating mRNA expressions of Bcl-2 family proteins, which trigger downstream signals culminating in caspase-3 activation followed by cell death. Depriving cultured PC12 cells of serum/glucose causes a rapid increase in cellular ceramide levels, followed by an increase in the risk of cell death. The accumulation of ceramide was found to depend on the activation of neutral sphingomyelinase (nSMase). Crocin prevented the activation of nSMase by enhancing the transcription of gamma-glutamylcysteinyl synthase, which contributes to a stable glutathione supply that blocks the activity of nSMase.

Levocarnitine propionate or Propionyl L-carnitine (PLC) is the propionyl ester of L-carnitine. Propionyl-L-carnitine stimulates energy production in ischaemic muscles by increasing citric acid cycle flux and stimulating pyruvate dehydrogenase activity. The free radical scavenging activity of the drug may also be beneficial. Propionyl-L-carnitine improves coagulative fibrinolytic homeostasis in vasal endothelium and positively affects blood viscosity. It exhibits a high affinity for the muscle enzyme, carnitine acyl transferase, and as such readily converts into propionyl-CoA and free carnitine. Most studies of the therapeutic use of PLC are focused on the prevention and treatment of ischemic heart disease, congestive heart failure, hypertrophic heart disease, and peripheral arterial disease. PLC is marketed under the trade name Dromos®. It is indicated for patients with peripheral arterial occlusive disorders and for exercise intolerance enhancement in patients with chronic congestive heart failure. Dromos is marketed in Italy.
