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.

Phenibut (beta-phenyl-gamma-aminobutyric acid or 4-amino-3-phenylbutyric acid) is a neuropsychotropic drug that was discovered and introduced into clinical practice in Russia in the 1960s. It has anxiolytic and nootropic (cognition enhancing) effects. It acts as a GABA-mimetic, primarily at GABA(B) receptors. Pharmacological activity of racemic phenibut relies on R-phenibut and this correlates to the binding affinity of enantiomers of phenibut to the GABAB receptor. In addition R-phenibut binds to the α2-δ subunit of voltage-dependent calcium channels. It is highly effective in treating anxiety, post-traumatic stress disorder, depression, asthenia, insomnia, alcoholism, stuttering, and vestibular disorders. It also improves mental performance (attention, memory, speed and accuracy of sensory-motor reactions), physical performance, reduces sleep disorders as well as movement and speech disorders.

Higenamine HCl (norcoclaurine) is a plant-based alkaloid widely used as nutritional supplement in food and beverage industries. It exists in variety of plants including Tinospora crispa, Nandina domestica, Gnetum Parvifolium C.Y. Cheng, sarum Heterotropoides, Nelumbo nucifera. It was initially isolated from Aconitum and identified as the active cardiotonic component of this medicinal plant used as local and traditional medicines in many Asian regions for the treatment of various diseases such as collapse, syncope, painful joints, oedema, bronchial asthma etc. Various pharmacological properties and potentially multi-spectral medical applications of higenamine have been reviled in many in vitro and in vivo studies conducted in animals and humans. Pharmacological properties of higenamine include positive inotropic and chronotropic effect, activating slow channel effect, vascular and tracheal relaxation effect, anti-thrombotic, anti-apoptotic and anti-oxidative effect, anti-inflammatory and immunomodulatory effect. Studies on higenamine showed potential therapeutic effects for diseases like heart failure, disseminated intravascular coagulation (DIC), shock, arthritis, asthma, ischemia/reperfusion injuries and erectile dysfunction. Higenamine has been tested as a candidate of pharmacologic stress agent in the detection of coronary artery diseases (CADs) in human clinical studies in China. In animal models, higenamine has been demonstrated to be a β2 adrenoreceptor agonist. It partly exerts its actions by the activation of adenylate cyclase, responsible for boosting the cellular concentrations of the adrenergic second messenger, cAMP. Via a beta-adrenoceptor mechanism higenamine, induced relaxation in rat corpus cavernosum, leading to improved vasodilation and erectile function. Related to improved vasodilatory signals, higenamine has been shown to possess antiplatelet and antithrombotic activity via a cAMP-dependent pathway, suggesting it may contribute to enhanced vasodilation and arterial integrity. Anti-apoptotic and cardiac protective effects of higenamine were shown to be mediated by the β2-AR/PI3K/AKT cascade. Higenamine is marketed as a dietary supplement for weight loss and sport performance, and is added to many fat burning supplements. Along with many other β2 agonists, higenamine is prohibited by World Anti-Doping Agency for use in sports.

Kavain is the main kavalactone found mostly in the roots of the kava plant. Kavain interacts with voltage-dependent Na+ and Ca2+ channels, GABAA ion channels. Kavain is found to be involved in TNF-alpha expression in human and mouse cells via regulation transcriptional factors. Kavain exhibits neuroprotective effects in models of Alzheimer's and Parkinson's diseases, and produces anxyolitic effect.

Citrulline malate (CM) is an organic salt made up of the non-essential amino acid L-citrulline and L-malic acid, an intermediate in the citric acid cycle. The main dietary source of citrulline is watermelon (Citrullus vulgaris), while malic acid is common to apples (Malus pumila) and grapes (Vitis vinifera). Initially, Citrulline malate was utilized as a pharmaceutical drug (STIMOL©, BIOCODEX Gentilly, France), for the treatment of patients suffering from asthenia to mitigate recovery time following physical activity. Citrulline malate has been purported to improve performance in both aerobic and anaerobic exercise modalities via a variety of mechanisms including improved ammonia and lactic acid metabolism, increased oxygen delivery capacity via increased vasodilation and increased adenosine triphosphate production via increases in Krebs cycle intermediates. Citrulline malate has been shown to increase lactate and ammonia clearance following exercise; this is via acting as a nitrogen ion acceptor during the first stage of the urea cycle. Supplementation may, therefore, improve ammonia-buffering capabilities reducing acidosis which occurs during intense exercise, as well as reducing muscle soreness post-exercise.

METHYLMETHIONINE (S-Methionine methyl sulfonium, SMMS) chloride is a derivative of methionine metabolism in some plants. Methylmethionine has therapeutic effects on gastrointestinal ulceration potentially via its ability to promote dermal fibroblast migration and growth. The natural derivative Methylmethionine is biosynthesized from L-methionine which is first converted to S-adenosylmethionine. The subsequent conversion, involving replacement of the adenosyl group by a methyl group is catalyzed by the enzyme methionine S-methyltransferase. Methylmethionine is particularly abundant in plants, being more abundant than methionine. S-Methylmethionine is sometimes referred to as vitamin U, but it is not considered a true vitamin. The term was coined in 1950 by Garnett Cheney for uncharacterized anti-ulcerogenic factors in raw cabbage juice that may help speed healing of peptic ulcers.

Thiamine disulfide is a vitamin B1 derivative. It is used as a component of vitamin complexes for the treatment of neurological and other disorders associated with disturbance of metabolic functions influenced by B-complex vitamins, including diabetic polyneuropathy, alcoholic peripheral neuritis and post-influenzal neuropathies, for the treatment of neuritis and neuralgia of the spinal nerves, especially facial paresis, cervical syndrome, low back pain, and ischialgia. It has being shown to be a potent inhibitor of human immunodeficiency virus (type-1) production, suggesting that thiamine disulfide may be important for AIDS chemotherapy.

Noopept (DVD-111) is a peptide promoted and prescribed in Russia and neighbouring countries as a nootropic. Noopept was patented by Russian-based pharmaceutical company JSC LEKKO Pharmaceuticals in the 1996. Research shows Noopept has similar effects, but works differently than other nootropics in the racetam-family. The compound is patented in both the US and Russia with patent of Russian Federation number 2119496, U.S. Patent 5,439,930 issued 8/8/1995. Noopept exhibits a combined neuroprotector effect both in vitro and in vivo. Noopept decreases the extent of necrotic damage caused by photoinduced thrombosis of cortical blood vessels. It was established that the neuroprotector effect of noopept is related to its action upon the well-known "triad", whereby the drug reduces neurotoxic effects of excess extracellular calcium, glutamate, and free radicals. Two additional components of the neuroprotector action of noopept are related to the antiinflammatory and antithrombotic activity.

Epicatechin gallate is one of the flavonoids, found in green tea and it acts as an antagonist of the mu/kappa/delta opioid receptors. Recently was studied the effect of epicatechin gallate on fructose uptake in human intestinal epithelia. Based on the result was made a conclusion, that epicatechin gallate could be a good candidate for preventing diseases caused by excessive fructose intake.

Vitexin, identified as apigenin-8-C-β-D-glucopyranoside, is a flavonoid compound found in Anthurium versicolor, Ficaria verna Huds. (Ranunculaceae), Cucumis sativus L. (Cucurbitaceae), and Acer palmatum (Aceraceae). Vitexin is an active component of many traditional Chinese medicines. Vitexin has recently received increased attention due to its wide range of pharmacological effects, including but not limited to anti-oxidant, anti-cancer, anti-inflammatory, anti-hyperalgesic, and neuroprotective effects.
