N-isopropyl-N'-phenylparaphenylenediamine (IPPD), an amine antiozonant, is used in rubber manufacture and is a human allergen.

Valine is an α-amino acid that is used in the biosynthesis of proteins. It is essential in humans, meaning the body cannot synthesize it and thus it must be obtained from the diet. There is a mixed scientivic evidence that as a dietary supplement valine improves training efficacy, delays central fatigue.

Alanyl-glutamine is a widely used alternative supplement to L-glutamine in the production of biopharmaceuticals. The primary advantage of using L-alanyl-glutamine in place of L-glutamine is that it reduces the level of ammonia generated during cell culture. L-alanyl glutamine also acts as an antioxidant (peroxide) and anti-apoptosis (LPS-induced) factor. Ala-Glu may be used in cell culture and insect cell culture applications. It can be used in studies on injury and sepsis, and in the effects of irradiation on leucine and protein metabolism in vivo. Alanyl-glutamine is used as dipeptide infusion solution, which is given as part of parenteral and/or enteral nutritional therapy. When the intake of nutrients or food into the mouth or directly into the gut is not possible or it is not enough to supply the body’s needs then nutrients or foods can be given intravenously or through the gastrointestinal tract or a combination of both. This is especially important for people whose bodies are under physical stress from illness or recent surgery. During illness or after surgery the body requires nutrition or food. Amino acids are the building blocks used by the body to make proteins. Dipeptiven is usually given as a supplement to amino acid solutions or an amino acid containing infusion regimen as part of complete nutritional support.

Acetyl-11-keto-beta-boswellic acid (AKBA), a pentacyclic triterpene, is a component of gum resin of Boswellia serrata. It inhibits 5-lipoxygenase in a selective, enzyme directed, non-redox, and noncompetitive manner. In addition, AKBA inhibited topoisomerase I. It induces apoptosis and exerts antineoplastic properties. 5-LOXIN, a dietary supplement ingredient (Boswellia serrata extract enriched with 30% 3-O-acetyl-11-keto-beta-boswellic acid) is effective in reducing pain and improving physical functioning in osteoarthritis patients.

Cafedrine, also known as norephedrinoethyltheophylline, is a chemical linkage of norephedrine and theophylline and is a cardiac stimulant used to increase blood pressure in people with hypotension. There are few data available for cafedrine. Cafedrine has a half-life of 60 min following both oral and intravenous administration Cafedrine is metabolized to norephedrine and several minor metabolites, but nearly 90% of the administered norephedrine is excreted via the kidneys, mostly unchanged, within 24 h. The effects of cafedrine on cardiac output are believed to be mediated via β- adrenoceptors. Cafedrine has a positive inotropic effect in humans, and this can be abolished by administration of the non-selective β-adrenoceptor antagonist propranolol. A combination of cafedrine and theodrenaline called Akrinor® is used for the treatment of hypotension in adults that occurs during emergency situations, general anesthesia, and regional anesthesia, especially during cesarean sections. Cafedrine/theodrenaline may have advantages over other vasopressor drugs. For example, it can be administered via bolus while catecholamines normally need to be diluted and administered via syringe pumps. Bolus injection is faster, which may be beneficial in emergency situations, plus it is more cost efficient with respect to the disposables. Cafedrine/theodrenaline has been widely used in Germany since 1963

Lymecycline is a tetracycline broad-spectrum antibiotic marketed by the pharmaceutical company Galderma. It is approximately 5,000 times more soluble than tetracycline base and is unique amongst tetracyclines in that it is absorbed by an active transport process across the intestinal wall, making use of the same fast and efficient mechanism by which carbohydrates are absorbed. Lymecycline's side effects can include rash, headache, diarrhoea, ulcerative colitis, nausea, vomiting, dermatitis, dysphasia, inflammation of the liver, hypersensitive reactions, and visual disturbances. When taken for a long period of time, it can cause reflux oesophagitis.
