Pentetrazol (pentylenetetrazole, BTD-001) is a pharmaceutical agent that displays activity as a central nervous system and respiratory stimulant. It is considered a non-competitive gamma-aminobutyric acid (GABA) antagonist. Pentetrazol (pentylenetetrazole) has been used experimentally to study seizure phenomenon and to identify pharmaceuticals that may control seizure susceptibility. GABA is thought to play a role in promoting sleep and its function is believed to be elevated in idiopathic hypersomnia. By blocking GABA’s function, pentetrazol (pentylenetetrazole, BTD-001) is expected to reduce excessive daytime sleepiness.

Fructose, or fruit sugar, is a simple ketonic monosaccharide found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. At a commercial scale, fructose is often derived from sugar cane, sugar beets, and maize. Fructose is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed directly into the bloodstream. A growing body of research suggests that diet high in fructose may be contributing to incidences of obesity, insulin resistance, and diabetes.
Coumarin itself was first isolated from the tonka bean Coumarouna odorata. Coumarin and its derivatives are alpha-benzopyrones. Coumarin is metabolized in humans to 7-hydroxycoumarin. Coumarin is a secondary phytochemical with hepatotoxic and carcinogenic properties. For the carcinogenic effect, a genotoxic mechanism was considered possible. Coumarins have a significant effect on physiological, bacteriostatic and anti-tumor activity. Coumarins have potent edema protective function and thus involved in the treatment of lymphedema, elephantiasis and other high protein edema conditions. Coumarin has appetite-suppressing properties.

Propionic acid (PA), also known as propanoic acid, with chemical formula C3H6O2, is an organic acid used as a food additive and found naturally on the skin and in the gastrointestinal tract. It is a byproduct of fermentation reactions and is also produced industrially from ethylene or ethanol and carbon monoxide. Propionic acid is a fungicide and bactericide, registered to controlfungi and bacteria in stored grains, hay, grain storage areas, poultry litter,and drinking water for livestock and poultry. As a food preservative, propionic acid prevents mold in bread and baked goods, and it is used as a flavoring agent in cheese and other packaged goods. The U.S. Environmental Protection Agency considers it safe and therefore, has no limitation on its use. It has been demonstrated that PA lowers fatty acids content in liver and plasma, reduces food intake, exerts immunosuppressive actions and probably improves tissue insulin sensitivity. Thus increased production of PA by the microbiota might be considered beneficial in the context of prevention of obesity and diabetes type 2. The molecular mechanisms by which PA may exert this plethora of physiological effects are slowly being elucidated and include intestinal cyclooxygenase enzyme, the G-protein coupled receptors 41 and 43 and activation of the peroxisome proliferator-activated receptor γ, in turn inhibiting the sentinel transcription factor NF-κB and thus increasing the threshold for inflammatory responses in general. Taken together, PA emerges as a major mediator in the link between nutrition, gut microbiota and physiology. The sodium salt of propionic acid was previously approved in Canada as an active ingredient in Amino-Cerv (used to treat inflammation or injury of the cervix).

Pastaron (Urea) is a waste product of many living organisms, and is the major organic component of human urine. It is a very important starting material in a number of chemical syntheses, and is used on an industrial scale for the manufacture of fertilizers, pharmaceuticals, and resins. Urea is an osmotic diuretic similar to mannitol but more irritant. Applied topically, urea promotes hydration of keratin and mild keratolysis in dry skin. It increases water uptake by the stratum corneum and has an antipruritic effect. Pastaron is used to soften rough or dry skin caused by skin conditions such as eczema, psoriasis, keratosis, and others.

Melatonin (5-methoxy N-acetyltryptamine) is a hormone synthesized and released from the pineal gland at night, which acts on specific high affinity G-protein coupled receptors to regulate various aspects of physiology and behaviour, including circadian and seasonal responses, and some retinal, cardiovascular and immunological functions. Melatonin is also made synthetically and available without a prescription as an over-the-counter (OTC) dietary supplement in the U.S. Melatonin supplementation has many uses, however, it has been widely studied for treatment of jet lag and sleep disorders. Parents may consider using melatonin to help their child who has a trouble falling asleep. A medical professional should always evaluate insomnia or other sleeping disorders in children. Additionally, melatonin has been shown to protect against oxidative stress in various, highly divergent experimental systems. There are many reasons for its remarkable protective potential. In mammals, melatonin binds to a number of receptor subtypes including high-affinity (MT1 and MT2) and low-affinity (MT3, nuclear orphan receptors) binding sites, which are distributed throughout the central nervous system and periphery.

Chlorobutanol, or trichloro-2-methyl-2-propanol, is an analgesic and sedative hypnotic in man, and an experimental general anesthetic. It has antibacterial and antifungal properties. It is also used chemical preservative for parenteral drugs. It was found, that chlorobutanol inhibited mammalian Nav 1.2 channels at concentrations less than those used to preserve parenteral solutions. Its mechanism of inhibiting Na channels differs from that of local anesthetics in that it does not show use dependent or state dependent inhibition.
