Betaine is a methyl derivative of glycine first isolated from the juice of sugar beets. Betaine is found in many common foods, but concentrated significantly in beets, spinach, wheat foods, and shellfish. In addition, betaine can be synthesized within the human body. Betaine participates in the methionine cycle, which produces vital biomolecules including proteins, hormones, phospholipids, polyamines, and nutrients. Betaine is used as a dietary supplement and has a beneficial effect on the human health. In the USA, FDA approved a betaine-containing drug Cystadane for the treatment of homocystinuria. The drug acts as a methyl group donor in the remethylation of homocysteine to methionine.

Since its discovery as component of the tea leaf by Albert Kossel in 1888, the history of theophylline (CAS 58-55-9) has been a long and successful one. At the turn of the century, theophylline became less expensive due to chemical synthesis and was primarily used as diuretic in subsequent years. It was Samuel Hirsch who discovered the bronchospasmolytic effect of theophylline in 1992, however, despite this pioneering discovery theophylline continued to be used primarily as diuretic and cardiac remedy. The molecular mechanism of bronchodilatation is inhibition of phosphodiesterase(PDE)3 and PDE4, but the anti-inflammatory effect may be due to histone deacetylase (HDAC) activation, resulting in switching off of activated inflammatory genes. Theophylline is indicated for the treatment of acute exacerbations of the symptoms and reversible airflow obstruction associated with asthma and other chronic lung diseases, e.g., emphysema and chronic bronchitis.

CHLORAL BETAINE, a chemical complex of chloral hydrate and betaine, is a nonbarbiturate sedative and hypnotic. It is indicated for sleep induction, preoperative sedation, and daytime sedation. CHLORAL BETAINE is converted to chloral hydrate in the body and its action on the central nervous system is identical with that of chloral hydrate.
