Dibutyl fumarate (DBF) is a plasticizer compound used in a number of products. However, it is banned from use in consumer products in the European Union after causing a widespread outbreak of dermatitis. The status of DBF as a skin irritant has been confirmed in animal studies. DBF apparently facilitates the trafficking of FITC-presenting CD11c(+) dendritic cells from the skin to draining lymph nodes and increases the cytokine production by draining lymph nodes.

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.

2,4-Dichlorophenoxyacetic acid (2,4-D) was the first synthetic herbicide to be commercially developed and has commonly been used as a broadleaf herbicide for over 60 years. It is a selective herbicide that kills dicots without affecting monocots and mimics natural auxin at the molecular level. 2,4-D was developed during World War II as one of many so-called phenoxy herbicides by aiming to increase crop yields for a nation at war. It was commercially released in 1946 becoming the first successful selective herbicide and allowed for greatly enhanced weed control in wheat, maize, rice, and other similar cereal crops because it specifically targets dicots. This herbicide family is said to have “initiated an agricultural revolution and laid the corner stone of present-day weed science” when it was first marketed in the 1940s.

Cuprous Sulfide (Cu2S) occurs in nature as the mineral and has very different two-dimensional lattice structures, along with excellent electro-catalysis and high conductivity. Recently published article has shown that nanocomposites incorporated with Cu2S nanoflowers can be used for skin tumor therapy and wound healing.

Valnemulin (marketed under the trade name Econor) is a pleuromutilin antibiotic used to treat swine dysentery, ileitis, colitis and pneumonia. It is approved for veterinary use only. Valnemulin is an antibiotic belonging to the pleuromutilin group, which acts by the inhibition of the initiation of protein synthesis at the level of the bacterial ribosome. Valnemulin has activity against a range of bacteria including those responsible for enteric and respiratory disease in pigs. Valnemulin shows high activity against Mycoplasma spp. and spirochaetes such as Brachyspira hyodysenteriae and Brachyspira pilosicoli. Valnemulin has little activity against Enterobacteriaceae, such as Salmonella spp. and Escherichia coli. There appears to be no resistance development to valnemulin to date by M. hyopneumoniae and L. intracellularis. There have been some increases of MICs of valnemulin against B. hyodysenteriae and to a lesser degree B. pilosicoli, some of which appear to have developed resistance. Valnemulin binds to the ribosome and inhibits bacterial protein synthesis. Resistance development primarily occurs because of changes at the binding site associated with mutations of the ribosomal DNA genes. Econor 10% and 50% is indicated for: The treatment and prevention of swine dysentery. The treatment of clinical signs of porcine proliferative enteropathy (ileitis). The prevention of clinical signs of porcine colonic spirochaetosis (colitis) when the disease has been diagnosed in the herd. Treatment and prevention of swine enzootic pneumonia. At the recommended dosage of 10 - 12 mg/kg bodyweight lung lesions and weight loss are reduced, but infection with Mycoplasma hyopneumoniae is not eliminated. Econor 0.5% and 1% is indicated: For the treatment and prevention of swine dysentery. The treatment of clinical signs of porcine proliferative enteropathy (ileitis). The prevention of clinical signs of porcine colonic spirochaetosis (colitis) when the disease has been diagnosed in the herd.

Pirlimycin is an antibiotic which was approved in the US and Europe for the treatment of subclinical mastitis in lactating dairy cattle associated with common mastitis pathogens, mostly Gram-positive bacterias. The drug exerts its action by binding to the 50S ribosomal subunit, therefore hindering the aminoacyl-tRNA binding and inhibiting the peptidyltransferase reaction, which interferes with protein synthesis within the bacteria.

Pyroglutamic acid (also known as PCA, 5-oxoproline, pidolic acid, or pyroglutamate for its basic form) exists as two distinct enantiomers: (2R) or D and (2S) or L. L-form is a metabolite in the glutathione cycle that is converted to glutamate by 5-oxoprolinase. L-Pyroglutamic acid is produced in the skin through the arginine-citrulline-ornitine-glutamic pathway. The free acid is not hygroscopic; however, the sodium salts of this acid are more hygroscopic than glycerine. Therefore, formulation of this acid is suggested as a defense against dehydration, for skin conditions involving desquamation. Hydromol Cream (main component of that is sodium pyrrolidone carboxylate (L form)) is a soft cream which moisturises the skin. Hydromol Cream contains a naturally occurring moisturising agent as well as oils, which prevent moisture loss from the skin. This helps to relieve itch, lubricate and soften the skin. Hydromol Cream is used to treat any condition in which dry skin is a feature such as eczema, ichthyosis (hereditary dry skin) and senile pruritus (itching that may occur in old age). L-Pyroglutamic acid is present in living cells has been reported from archaebacteria to humans, and its occurrence in living cells has been known for over a century. Despite its almost ubiquitous presence, the role of pyroglutamic acid in living cells is poorly understood. Pyroglutamic acid is found as an N-terminal modification in many neuronal peptides and hormones that also include the accumulating peptides in Alzheimer’s disease and familial dementia. The modification is also observed in proteins that include many antibodies, some enzymes and structural proteins.

Sodium dehydroacetate, a water-soluble antiseptic, is a food and feed additive with antimicrobial effects. Recently published studies have shown that sodium dehydroacetate in patients with leg ulcers could cause allergic contact dermatitis.
