Cetyl oleate is a cosmetic emollient ester

2,5-Dimethyl-N-Phenyl-3H-diazaphophol-4-imine is a quinonoid tautomer of GABAA and GABAB agonist progabide. According to quantum mechanical calculations, a quinonoid form is predominant in polar solvents, while aromatic tautomer is prevalent in apolar solvents. Progabide is a prodrug of gamma-aminobutyric acid and was investigated for the treatment of epilepsy, Parkinson's disease, schizophrenia, clinical depression, anxiety disorder, and other diseases. Progabide was marketed in France by Sanofi Aventis under tradename Gabrene for use in monotherapy and also as adjunctive therapy for generalized tonic-clonic, myoclonic, partial seizures, and for Lennox‐Gastaut syndrome, in both children and adults.

Doconexent (Docosahexaenoic acid, DHA) is an omega-3 fatty acid that is a primary structural component of the human brain, cerebral cortex, skin, and retina. DHA is widely used as a food supplement, and is beleived to support healthy brain development in young childred, prevent cardiovascular disease and cognitive decline during Alzheimer's disease. Most of these claims, however, were not supported by clinical trials. DHA spray is used as a tanner.

Carnosine is a dipeptide composed of the amino acids beta-histidine and l-alanine. It is widely present in muscle and brain tissues. It possesses strong and specific antioxidant properties, protects against radiation damage, and promotes wound healing. The antioxidant mechanism of carnosine is attributed to its chelating effect against metal ions, superoxide dismutase (SOD)-like activity, ROS and free radicals scavenging ability. In addition, was shown, that carnosine significantly protects against TCA-induced liver carcinogenesis in rats, through its antioxidant, antinutritive, and anti-inflammatory effects, and induction of apoptosis. It also may be a therapeutic agent against Parkinson's disease. Experiments on animal have shown the sepsis healing therapeutic potential of carnosine.

Creatine is an amino acid that occurs in vertebrate tissues and in urine. It is synthesized mainly in the liver from three different amino acids: arginine, glycine, and methionine. In skeletal muscles, which store 95% of it, creatine generally occurs as phosphocreatine. The rest is stored in the brain, heart, and testes. Creatine functions as part of the cell's energy shuttle. It is excreted as creatinine in the urine.

Selenocysteine is a naturally occurring amino acid. It is analog of cysteine where thiol (-SH) group is replaced by selenol (-SeH) group. 54 human proteins are known to contain selenocysteine. Among them are eukaryotic elongation factor, glucose-6-phosphate dehydrogenase, glutathione peroxidase, and others. Selenocysteine is contained in meat, fish, cheese, cereals, Brazil nut and walnuts.

Glutathione (GSH, also called as reduced glutathione) is a tripeptide with many roles in cells. It conjugates to drugs to make them more soluble for excretion, is a cofactor for some enzymes such as, glutathione reductase, glutathione peroxidases, peroxiredoxins. Glutathione S-transferases catalyse the conjugation of GSH via a sulfhydryl group to electrophilic centers on a wide variety of substrates in order to make the compounds more water-soluble. As a part of homeopathic product, glutathione is used for temporary relief of symptoms related to Free Radical Toxicity including tingling in hands and feet, mood changes, frequent colds, poor digestion, fatigue, and constipation. In addition, for temporary relief of pain in the back from urinating, constant urging and frequent urination, kidneys sensitive to pressure, and pain from back extending down the thigh. Glutathione is an important nutrient for brain function and loss of glutathione has been implicated in Parkinson's disease. In phase II of the clinical trial was investigated whether administration of either dose of glutathione, as a nasal spray, improves PD symptoms over time in a population of individuals with Parkinson's disease (PD). In addition in phase II of clinical trial was shown, that reduced glutathione, an ingredient of RayGel™, has been helpful in decreasing some radiation therapy side effects to the skin. Reduced glutathione plays a vital role in both making DNA and cell repair. Cystic fibrosis (CF) is the most common inherited disease among the Caucasian population with considerable morbidity and reduced life expectancy. Glutathione (GSH) represents the first-line defence of the lung against oxidative stress-induced cell injury. Therapeutic approaches with inhaled GSH could improve the reduced lung antioxidant capacity in order to counterbalance the oxidant stress linked to the chronic airway inflammation and bacterial infection.

Zinc Pidolate (Zinc PCA) is a topical skin product with purifying, astingent, anti-inflammatory, antiseptic activity. It has long been used as a cosmetic ingredient, because of its astringent and anti-microbial properties. Zinc Pidolate has also being shown to be effective against halitosis. Zinc PCA prevents the UV-induced MMP-1 production in vitro by suppressing the activation of AP-1. Zinc PCA was also able to enhance type I collagen synthesis in NHDFs, by increasing the expression of the mRNA encoding the ascorbic acid transporter SVCT2 in non-UV irradiated NHDFs, which suggests its promising effect against not only photoaged skin but also for the simple atrophic change of intrinsic skin ageing. Zinc PCA is able to suppress sebum secretion by inhibiting 5-α reductase in hyperseborrhea, to suppress body odor by forming zinc salts with short-chain fatty acids, to suppress wrinkles by inhibiting AP-1 to and inhibit bacterial growth including acne related Propionibacterium acnes.

Mandelic acid is an aromatic alpha hydroxy acid that is used for the treatment of urinary tract infections. The drug is marketed in Canada under the name Mandelamine (as a complex with methenamine). Mandelic acid exerts its antibacterial effect mainly by increasing urine acidity. Moreover, mandelic acid is used as a serum for the treatment of wrinkles.
