Acetophenone is an organic compound with major use in the chemical industry for the polymerization of olefins, and organic synthesis as a photosensitizer and as a specialty solvent for plastics and resins. It is also a chemical intermediate for the odorant ethyl methyl phenylglycidate, the riot control agent 2-chloroacetophenone and 2- bromoacetophenone for dyes. It is used in the manufacture of pharmaceuticals, rubber, dyes, and corrosion inhibitors. Acetophenone was approved by the FDA as a flavoring substance and adjuvant in food. It is used as a flavoring agent in non-alcoholic beverages, ice cream, candy, baked goods, gelatins, puddings, tobacco, and chewing gum. It is used to impart an orange-blossom fragrance in soaps, detergents, creams, lotions, and perfumes.

Clothiapine is a neuroleptic of dibenzoepine class that ise used for the treatment of mental disorders. It is supposed that clothiapine acts by blocking GABA (A) receptors. The drug is marketed in some European countries under the name Entumin.

β-ionone shown to be a key intermediate in the synthesis of vitamin A. Can be isolated from the volatile oil of Boronia megastigma Nees, Rutaceae or by condensing citral with acetone. From animal experiments it can be concluded that β¬-ionone is absorbed after oral exposure. Metabolism takes place mainly in the liver. ¬ β-Ionone has only low acute toxicity after oral ingestion. The substance naturally occurs as a biogenic volatile organic compound and shows a ubiquitous occurrence in the air due to emissions from plants or surface waters.

Butyric acid (butanoic acid) belongs to a group of short-chain fatty acids and is thought to play several beneficial roles in the gastrointestinal tract. The butyric anion is easily absorbed by enteric cells and used as a main source of energy. Moreover, butyric acid is an important regulator of colonocyte proliferation and apoptosis, gastrointestinal tract motility and bacterial microflora composition in addition to its involvement in many other processes including immunoregulation and anti-inflammatory activity. Butyric acid shows a protective effect in inflammatory response secondary to inflammatory bowel diseases. A beneficial effect of butyric acid as one constituent of a multifaceted mechanism modulating gastrointestinal function has also been stressed in patients with the stoma and coexisting constipation. Butyric acid supplementation combined with the use of probiotics should be adopted as one of the basic therapeutic strategies in this patient group, preceding treatment with laxatives. Sodium butyrate in the form of enemas (combined in a mixture with A-300 silicon dioxide) may be a successful method of therapeutic management in patients with radiation proctitis. Sodium butyrate may also prevent diarrhea through an increased passive absorption of water in the colon and its effects on the gut microflora.
